INSTRUMENT SURFACE

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to U.S. Provisional Patent Application Serial Number 62/675,371, filed May 23, 2018, the entire contents of which are incorporated herein by reference.

BACKGROUND INFORMATION

In certain instances it can be desirable to clean a surface of an elongated instrument while the surface is held in a cavity. For example, during laparoscopic surgery the vision through the laparoscope may be impaired. For example, the scope may become fogged, or the scope may be smeared by blood or other bodily fluids or tissues ( e.g . interstitial fluid or fat tissue).

Currently, two different scope cleaning methods are commonly utilized. One method is to remove the laparoscope from the body, wipe the lens with a cloth, and reinsert it into the body. This method, though effective, is time consuming and causes the surgeon to lose visual of the surgical site, which can be considered dangerous, as surgical instruments typically remain inside the body.

The action of cleaning the laparoscope increases the length of time each surgical procedure takes, as well as decreases the amount of operating room (OR) time available to the hospital. Additionally, as patients undergo longer procedures, their time spent under anesthesia increases. As increased time under anesthesia has been shown to correlate to a rise in surgical complication rates and post-surgical infection rates, this excess time is not only wasteful, but also potentially medically and financially costly.

{00662631} 1 The other method is to wipe the laparoscope lens upon a nearby organ or tissue. While the laparoscope remains inside the body and takes less time to clean, this method is not often effective. When using either method, the surgeon must spend time relocating the surgical site within the body. The entire process is a hindrance and an annoyance for surgeons at minimum. Also, it is costly for hospitals, patients, and insurance companies due to wasted time, and possibly surgical complications and post-surgical infections.

Methods comparable to those discussed above (i.e. referring to the field of laparoscopy), are commonly utilized in different fields at the appropriate scale. For example, in down hole drilling applications, instruments that become dirty with debris may need to be removed from the hole and cleaned before resuming use.

There is presently a shortage of methods and devices that provide for effective devices and methods to clean a surface of an elongated instrument held within a cavity. Exemplary embodiments of the present disclosure address these shortcomings. SUMMARY

Exemplary embodiments of the present disclosure allow for rapid and easy cleaning of an instrument held within a cavity. For example, this may include cleaning a laparoscope in vivo, negating the need for instrument removal from the body.

Embodiments of the present disclosure allow for users of elongated instruments (including for example, laparoscopes or other medical instruments, down hole drilling cameras and equipment, etc.) to clean a surface of the instrument without having to notably remove the instrument from its place of use. For example, in the case of an technology application for a laparoscope, the present disclosure would allow for the user to clean a surface of a laparoscope ( e.g . a lens) in vivo, without having to remove the scope from the body. It therefore

{00662631} 2 significantly decreases the time it takes to clean the instrument surface as compared to current technologies, relieving a vast amount of the technical and financial pains placed on stakeholders. For example, in the case of a laparoscopic application, vast amounts of medical and financial pains may be significantly mitigated by the improvement of an in vivo laparoscope cleaner, thereby benefiting hospitals, clinicians, patients, and third-party payers.

Exemplary methods of cleaning an instrument include mechanical, optical, and pneumatic applications to clear unwanted objects, contaminants, particles, etc. from lens of the instrument.

One mechanical embodiment utilizes a proximal member that extends for the length of a laparoscope. This proximal member has a cleaning tip at the distal (lens) end of the laparoscope that allows for cleaning of the laparoscope lens. It also have a base end as well, where the user primarily interacts with the system/device.

This application may use a surface cleaning material at the distal tip to be swept, dragged, rotated, etc. across the lens. The mechanism of this cleaning actuation may be designed to actuate with a passive mechanism that only cleans with relative translation between the scope and proximal member. The mechanism may also be designed to actuate with an active mechanism that cleans when the user implements fine-tuned control of the cleaning tip.

This application may implement materials including one or multiple types of cleaning components, such as deformable, flexible, and/or absorbent components (i.e. rubber, bristles, sponges, etc.) (will be referred to as“components” for the remainder of this document). These components may allow for the cleaning of the scope without any further addition. These components may also provide for enhanced cleaning with the inclusion of additional cleaning material, such as a cloth, foam, sponge, ribbon, etc. (will be referred to as“ribbon member” for the remainder of this document). This cloth may have a material or geometrical alteration for

{00662631} 3 improved cleaning performance (e.g. napped/fuzzy surface, microfiber structure, ideal porosity and absorbance) in addition to improved interaction with the rest of the device (distal, proximal, and base ends of device) (e.g. ideal friction relationship, thickness for trocar compatibility, etc.). As these aforementioned components deform, they allow for the ribbon to conform about the scope surface, applying an adequate force/pressure on the ribbon to improve cleaning efficacy of the ribbon. As the components deform, their deformation may prove two-fold in application, as they (1) store energy, and generate higher cleaning forces/pressures on the surface (possibly translated via a ribbon) and (2) allow for more ideal conformation and improve force/pressure distribution to the surface, and possibly allow for more ideal conformation and improve force/pressure distribution of a cleaning ribbon to the surface.

It should be noted that the ribbon itself may act as its own deformation component or compressible member if its structure allows for it. This could include its material or geometrical configuration. It has been shown that altering its contact approach (e.g. parallel vs. perpendicular, flat vs. twisted orientation, etc.) can alter cleaning performance and interaction performance with the rest of the device.

It should also be noted that the ribbon member may be a belt that cycles on a single spool or it may be fed by one spool, in one direction, and received by a different spool (e.g. one spool feeds ribbon while another spool receives ribbon). These spools may be on the same shaft, or a different shaft. These spools, and/or the ribbon, may be held with tension that allows for potentially more convenient device interfacing, or held with slack, allowing for potentially improved conformation to scope surface. Actuation of the spools may be controlled by the user, or may be automated. It is important to recognize that the inclusion of tension in the ribbon may alter cleaning performance, as the contact points of the ribbon on the scope may actually cause the ribbon to reduce contact/contact force on the scope surface. This highlights the

{00662631} 4 importance of the aforementioned components, and their ability to conform to the scope surface (possibly via/translated to the ribbon).

The aforementioned components may or may not be soaked/coated in a solution that assists in the removal of unwanted objects, contaminants, particles, etc. from the surface of the elongated instrument that is to be cleaned. Delivery of this solution may be actively controlled by the user, or passively controlled by the cleaning actuation mechanism. This solution may be housed in the cleaning tip, along or inside the proximal member, or at the base of the proximal member, or all of the above. This solution may or may not be a saline solution, or a surfactant solution that appropriately and adequately removes bodily fluids and tissues from the surface, including but not limited to condensation, blood, interstitial fluid, fat tissue, etc.

In another embodiment, a cut may be made in the wall of the proximal member. This cut may alter the geometry of the proximal member to allow for storage of energy, and translation/rotation of the proximal tip. One example is a slit on a single side of the distal tip. When the scope contacts the components/ribbon in the distal tip, energy storage occurs, and eventually, the geometry and energy storage/release causes the distal member to deflect/fall out of view of the surface, allowing for the surgeon to see again. Another example is the cut of a spring-like geometry into the proximal member. This geometrical cut operates similarly to the single slit, but also allows for improved energy storage, in addition to a torsional/rotational motion that is translated to the distal tip, potentially increasing surface coverage. Additionally, the tip itself may be made into a coil-spring geometry after geometrical cuts and potential forming techniques, offering comparable benefits as previously explained.

In another embodiment, an elastic component may drag over the scope surface to allow for energy storage, component deformation, and improved cleaning via applied force/pressure and conformation to surface. This elastic component may/may not have a ribbon included, for reasons and interactions previously mentioned. It is worth noting that if a ribbon is included,

{00662631} 5 the tensioning, or even the cycling of a slack ribbon, when interacting with this elastic component, may lead to the stretching of the elastic component. This means that actuation could be made separate from contact, as was described in previously mentioned embodiments. It should be noted that such an actuation could also be included in previous embodiments, with proper integration of this elastic component.

Exemplary embodiments of the present disclosure fit around or beside the laparoscope and inside a trocar port. The scope is retracted back until it is a set/particular distance above the aforementioned components/ribbon/combination. It is then pushed into contact with and eventually passed the components/ribbon/combination, and cleaning may occur. The cleaning may occur within this passively actuated cleaning event. During this cleaning event, the ribbon, if included, may be held“fixed” relative to the spool/components, and still allow cleaning. The ribbon would be rotated/cycled/fed either before or after each cleaning event. Alternatively, the ribbon may be actively rotated/cycled/fed during the cleaning event (i.e. ribbon is rotated as comes into contact and eventually passes the aforementioned components. It has been shown that the latter method may prove to be a more effective cleaning approach (i.e. extended pressure with new cleaning material passing over scope) while the former method may still clean effectively with a minimal number of actuations (currently estimated 1-5 actuations), though may stand to be less repeatable and reliable, when compared to the latter method.

Both of these aforementioned mechanical embodiments are unique and different from current technology due at least in part to the fact that the cleaning mechanisms and/or combinations of mechanisms have unique geometric and/or material and/or orientation (arguably geometrical as well) specifications that are key to its performance. This is especially important and novel due to the fact that a single configuration (primarily relating to inner diameter) of the present disclosure can clean multiple styles of laparoscopes ( e.g . different

{00662631} 6 angles) at the same efficiency - e.g. flat scopes, 30° scopes, 45° scopes, etc. Current technologies do not appear to allow for this.

Exemplary embodiments of the present disclosure are compatible with current laparoscope-trocar pairings. Current technology does not appear to allow for this. For example, a 5 mm laparoscope (approximately 5.0-5.5 mm diameter) fits inside a common 5 mm trocar port (approximately 7.1 mm diameter). Current technology seems to require a larger port. Exemplary embodiments of the present disclosure, due to novel and elegant mechanisms, can be made to fit within those smaller tolerances.

One mechanical embodiment utilizes high frequency vibration either onto the laparoscope directly, or onto a mechanical component that in turn vibrates the laparoscope at a high frequency. One optical embodiment utilizes optical intensity, frequency, continuous and/or pulsed light methods to remove debris from the surface. These light parameters can be altered via an attachment, or a built-in system.

Certain embodiments utilize a longitudinal member and a transverse member at the distal (surface) end of the laparoscope to be moved (e.g. swept, dragged, rotated, etc.) across the surface. In such embodiments, the transverse member may or may not be soaked or coated in a solution that assists in the removal of unwanted matter (e.g. objects, contaminants, particles, etc.) from the surface of the laparoscope. In certain embodiments, the solution may or may not be a saline solution, or a surfactant solution that appropriately and adequately removes bodily fluids and tissues from the surface, including but not limited to condensation, blood, interstitial fluid, fat tissue, etc.

Certain embodiments may implement surface cleaning materials, including one or multiple types of transverse members, such as flexible and/or absorbent components such as bristles, wipers, or sponges, with a longitudinal member configured as an elongated tube, rod,

{00662631} 7 bar, or sheet. In some embodiments, the tube or rod fits around the laparoscope and inside a trocar. The distal end of the tube or rod can hold or house the transverse member (or members) that act as cleaning components. The scope can then be positioned (i.e. the scope retracted back or the tube or rod pushed forward) until it is a specific distance above the aforementioned cleaning components. The scope can then be pushed into and past the transverse member(s), which can perform a majority of the cleaning, at effective forces due to the stiffness and/or material properties of the transverse member(s), and the total combined surface area coverage.

In certain embodiments, an absorbent or sponge material may be implemented at the distal end of the longitudinal member to absorb or clean any remaining droplets or particles of elements that were not removed via the transverse member, if necessary. Exemplary embodiments of the device can clean different angled scopes of similar diameters with comparable efficacy.

Exemplary embodiments of the present disclosure comprise cleaning mechanisms and/or combinations of mechanisms with unique geometric, material and/or orientation specifications that provide the ability to effectively remove matter from an elongated instrument surface held within a cavity.

In particular embodiments, a single configuration of the device can clean multiple styles of laparoscopes ( e.g . different angles such as flat scopes, 30 degree scopes, 45 degree scopes and 70 degree scopes) at a relatively equivalent efficiency. Exemplary embodiments are also compatible with current common laparoscope-trocar pairings, in contrast to typical existing systems. For example, a 5 mm laparoscope (approximately 5.0-5.5 mm diameter) can fit within a common 5 mm trocar port (approximately 7.1 mm diameter). Current systems can require a larger port, while exemplary embodiments of the device disclosed herein can be made to fit within these tolerances.

{00662631} 8 Certain embodiments utilize one or more geometrical rubber/foam mats/wipers fixed to the distal end of the device. As a scope is retracted into the sheath, the rubber wiper comes to rest in a passive position. As the scope is then pushed forward into the rubber wiper, the geometry and material of the wiper, in addition to its positioning relative to the scope surface allows the wiper to“scrape”, slide, or drag across the surface, comparable to that of a windshield wiper.

Certain embodiments utilize high frequency vibration either onto the laparoscope directly, or onto a mechanical component that in turn vibrates the laparoscope at a high frequency. Particular embodiments utilize optical intensity, frequency, continuous and/or pulsed light methods to remove debris from the surface. These light parameters can be altered via an attachment, or a built-in system.

Certain exemplary embodiments comprise a sheath that fits around a laparoscope or other type of cylindrical or tubular device that might require cleaning at a distal end (i.e. an endoscope). Particular embodiments include a transverse member that functions as a cleaning mechanism at the distal end of the device. In specific embodiments, the cleaning mechanism may comprise a hook-like, claw-like, broom-like, squeegee-like, or scraper-like geometry or configuration. During operation of exemplary embodiments, a component at a distal end of the transverse member is drawn across the surface, thereby cleaning debris from the surface.

In particular embodiments, the transverse member may be formed from a material comprising (or include a coating comprising) rubber, foam, plastic, or cloth material that does not scratch, harm, or impede the surface to be cleaned. In certain embodiments, the transverse member may include bristles, wipers, or an absorbent material (e.g. a material that is foam or sponge-like in nature). In specific embodiments, the transverse member may include a particular surface texture, including for example a surface finish of 0.01 microns - 1000 microns, or more particularly 0.1 - 100 microns, or more particularly 1.0 - 10 microns.

{00662631} 9 In specific embodiments, the transverse member may include a surface porosity of 0 - 75 percent porosity, or more particularly 10 - 50 percent porosity, or more particularly 20 - 35 percent porosity.

In specific embodiments, the transverse member may include a particular rigidity, resilience, and/or flexibility to promote effective matter removal from the surface of the elongated instrument. In certain embodiments, the material of the transverse member may have an elastic modulus of 0.005 - 5 gigapascals (GPa), or more particularly 0.05 - 2.0 GPa, or more particularly 0.5 - 1.5 GPa.

In some embodiments, the distal end of the transverse member may comprise a particular geometry of the cleaning edge ( e.g ., sharpened, rounded, multi-pronged, etc.). In certain embodiments, the transverse member may include particular component angles and radii of approach and implementation where the transverse member is coupled to the longitudinal member (which may be configured as a sheath). For example, the angle between the transverse member proximal end and the longitudinal member may be between 0 - 90 degrees, or more particularly between 15 and 60 degrees, or more particularly between 30 and 45 degrees. In addition, the angle between the transverse member distal end and the surface to be cleaned may be between 0 - 180 degrees, or more particularly between 15 and 135 degrees, or more particularly between 30 and 90 degrees or more particularly between 45 and 60 degrees. In addition, the transverse member can be configured so that it is able to remain out of view of the elongated instrument, including adjacent to or near the elongated instrument, as the user desires.

During operation of the device, it can expel dirty material from the surface and/or cleaning surface of the transverse member. Certain embodiments may also include an

{00662631} 10 additional mechanism with the ability to convert stored potential energy to kinetic energy, including for example, a vibrational or“flick” mechanism. In certain embodiments, such a mechanism could be activated after transverse member initially moves across the surface of the elongated instrument. In certain laparoscopic embodiments, the device can be configured such that it is compatible with current commonly paired apparatus (e.g. a 5 mm diameter laparoscope with a commonly paired trocar). In certain embodiments, the device may be used in conjunction with an elongated instrument having a shaft with a diameter of approximately 2.7 mm - approximately 12.0 mm and a trocar having a diameter of approximately 3.0 mm - 13.0 mm. In particular embodiments, the device may include a transverse member that is curved and has a radius of curvature of 1.3 mm - 12.5 mm, or more particularly 2.0 mm - 10.0 mm, or more particularly 3.0 mm - 9.0 mm, or more particularly 4.0 mm- 8.0 mm, or more particularly 5.0 mm to 7.0 mm. In specific embodiments, the device may include a longitudinal member that is tubular and had a diameter between approximately 3.0 mm and approximately 13.0 mm. In certain embodiments, the device may comprise a constraint that aligns the transverse member appropriately with the surface of the elongated instrument to be cleaned. This can be particularly important for compatibility with different angled surfaces. Exemplary embodiments can be actuated easily and quickly by manual or automated means, potentially via human input, robotic or mechanical input, or pneumatic input. Exemplary embodiments include a device configured to clean a surface of an elongated instrument held within a cavity. In certain embodiments, the device comprises a longitudinal member comprising a proximal end and a distal end, and a flexible transverse member comprising a proximal end and a distal end, where the proximal end of the flexible transverse member is coupled to the distal end of the longitudinal member.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

Referring now to FIG. 1, an exemplary embodiment of a device 100 is shown during use cleaning an elongated instrument 200. In the embodiment shown, device 100 is configured to clean a surface 210 ( e.g . a lens) of elongated instrument 200 held within a cavity (e.g. in vivo). In this embodiment, device 100 comprises a longitudinal member 110 comprising a proxmial end H i and a distal end 112. Device 100 also comprises a flexible transverse member 120 comprising a proximal end 121 and a distal end 122, where proximal end 121 of flexible transverse member 120 is coupled to distal end 112 of longitudinal member 110. As used herein, distal end 112 of longitudinal member 110 comprises a region of longitudinal member 110 that is distal from proximal end 112. Accordingly, a portion (e.g. 5, 10 or 20 percent) of longitudinal member 110 may extend beyond the coupling point of flexible

{00662631} 32 transverse member 120 and longitudinal member 110 (e.g. may extend aw'ay from proximal end I l l). in certain embodiments, longitudinal member 110 and flexible transverse member 120 may be formed from a unitary component, while in other embodiments, longitudinal member 1 10 and flexible transverse member 120 may be separate components.

In FIG. 1, device 100 is shown during use with progression of steps from left to right in the far left view, device 100 is shown in its unaltered position (e.g. before surface 210 has moved distal end 122 of flexible transverse member 120). In the view's moving to the right in FIG. 1, elongated instrument 200 is moved relative to device 100 in the direction indicated by arrow's 220. As elongated instrument 200 is moved in this direction, surface 210 is moved in a direction parallel to longitudinal member 110 and away from distal end 111. Surface 210 exerts a force on distal end 122 of flexible transverse member 120 during the movement of elongated instrument 200 relative to device 100.

When surface 210 exerts a force on distal end 122, transverse member 120 is configured such that distal end 122 moves away from proximal end 121 of flexible transverse member 120. In exemplary embodiments, distal end 122 is configured to remove matter 213 from surface 210 when distal end 122 moves across surface 210 toward proximal end 121 of transverse member 120.

When surface 210 is a lens (e.g. and elongated instrument 200 is a laparoscope) the removal of matter 213 from surface 210 can allow a user to more clearly view a subject area being examined by elongated instrument 200. A simulated view 215 through elongated instrument 200 is shown below device 100 and elongated instrument 200 in FIG. 1. As shown in the progression of steps from left to right, as matter 213 is removed from surface 210, the

For example, m certain embodiments, longitudinal member 110 may be configured as a tubular member such that a shaft of elongated instrument 200 is disposed within the tubular member. In specific embodiments, longitudinal member 1 10 may be a tubular member configured to be disposed within a trocar, such that longitudinal member 110 is located between the trocar and elongated instrument 200.

The embodiment of FIG. 1 illustrates elongated instrument 200 moving in a direction of arrow 220. However, it is understood that device 100 may instead be moved in a direction opposite of arrow 220. Device 100 is configured to remove matter 213 from surface 210 when the relative position between device 100 and elongated instrument 200 is changed while distal end 122 is engaged with surface 210 (such that the distance between proximal end 111 and surface 210 is increased). Accordingly, device 100 is configured to clean surface 210 whether device 100 is held stationary' and elongated instrument 200 is moved, or device 100 is moved and elongated instrument 200 is held stationarjg or if both device 100 and elongated instrument 200 are moved.

It is understood that transverse member 820 may be configured such that second end 822 is located closer to intermediate member 815 when device 800 is not in use (re. transverse member 820 may be substantially parallel to intermediate member 815 when not in use).

Referring now to FIG. 8, another embodiment comprises a device 900 for cleaning a surface of an elongated instrument held within a cavity. This embodiment includes a longitudinal member 910 configured as a tubular member. In addition device 900 comprises a transverse member 920 coupled to a distal end 912 of longitudinal member 910. In this embodiment, transverse member 920 comprises a first flexible member 925 and a second flexible member 926 that extend across distal end 912. First and second flexible members 925 and 926 are configured to move across a surface at an angle to the longitudinal member when the surface moves past the distal end of the longitudinal member. Accordingly, first and second flexible members 925 and 92.6 can assist in removing matter from a surface of an elongated instrument during use.

In certain embodiments, first and second flexible members 925 and 926 can be spaced apart such that the surface passes between flexible members. It is understood that the spacing first and second flexible members 925 and 926 shown in FIG. 8 is merely exemplary for illustration purposes. In certain embodiments, first and second flexible members 925 and 926 may be adjacent such that both flexible members pass to one side of the surface as the surface extends past distal end 912. In particular embodiments, first and second flexible members 925 and 926 may be formed from a unitary loop of material (e.g. rubber or other suitable material) that is coupled to distal end 912.

{00662631} 38 Referring now to FIG. 9, another embodiment of a device 1100 is shown during use cleaning an elongated instrument 1200. In the embodiment shown, device 1100 is configured to clean a surface 1210 ( e.g . a lens) of elongated instrument 1200 held within a cavity (e.g. in vivo). In this embodiment, device 1100 comprises a longitudinal member 1110 comprising a proximal end 1111 and a distal end 1112. As used herein, the term“distal end” refers to an end portion of a device that is distal to a user during operation of the device, while the term “proximal end” refers to an end portion of a device that is proximal to a user during operation of the device. In exemplary embodiments disclosed herein, the distal end of the device would be located in a cavity during use, while the proximal end would be located external to the cavity during use.

Device 1100 also comprises an intermediate member 1115 and a transverse member 1120, as well as a compressible member 1121 and a control member 1 122. In certain embodiments, longitudinal member 1110, intermediate member 1115 and transverse member 1120 may be formed from a unitary' component, while in other embodiments, longitudinal member 1 1 10, intermediate member 1115 and flexible transverse member 1 120 may be separate components. Exemplary compressible members include foam, rubber and other suitable materials that are capable of being compressed to reduce the thickness of the material when pressed against the surface to be cleaned. In addition, exemplary compressible members include members that may be convex in shape (e.g. bowed outward toward the surface to be cleaned) and slightly deflect or compress when applying a force against the surface to be cleaned. Such convex-shaped compressible member configurations do not necessarily result in a reduced thickness of the material when pressed against the surface to be cleaned.

Device 1100 further comprises a ribbon member 1130 extending across distal end 1112 to assist in cleaning a surface of elongated instrument 1200. As used herein,“ribbon member” includes any long, flexible material capable of conforming to a surface of elongated instrument

{00662631} 39 1200 to assist in cleaning. Examples of suitable materials include silk polyester materials, microfiber, napped material, cloth, foam, rubber, etc. Exemplary ribbon members may comprise cross-sections with round, rectangular, square, polygonal or other suitable shapes in certain embodiments, exemplary ribbon members may be configured as a belt or loop. Ribbon member 1 130 is shown extending through guides 1 131 (configured as slots m transverse member 1 120 in this embodiment) such that ribbon member 1130 extends across elongated instrument 1200 in a direction generally parallel to intermediate member 1115. In other embodiments, ribbon member 1130 may extend generally perpendicular to intermediate member 1115.

During operation, a user can extend elongated instrument 1200 (or retract device 1 100) until elongated instrument 1200 contacts ribbon member 1130 and ribbon member 1130 contacts compressible member 1121. Compressible member 1121 can exert a force on ribbon member 1130 and elongated instrument to ensure ribbon member 1130 maintains contact with elongated instrument 1200. This compressive force can be particularly important in the cleaning of elongated instrument 1200 when the surface of elongated instrument 1200 is not completely flat. For example, if the surface of elongated instrument 1200 includes a raised lip, ridge or bevel around the outer circumference, it can be difficult to clean the area within the raised circumference. The ability of compressible member 1121 to apply a force on ribbon member 1130 in the direction of elongated instrument 1220 is also important in maintaining contact when ribbon member 1130 is pulled across the surface of elongated instrument 1200.

The ability to pull ribbon member 1130 across the surface of elongated instrument 1200 significantly increases the surface area of cleaning material available to clean elongated instrument 1200 held within a cavity . As explained further below, ribbon member 1130 may be pulled from a spool of material that provides orders of magnitude greater surface area than other cleaning configurations. The ability to provide“new” cleaning material (e.g. cleaning

{00662631} 40 material that has not contacted elongated instrument 1200) to the surface to be cleaned provides significant advantages held within a cavity. Medical procedures using laparoscopes (or other devices that require cleaning) can last for significant periods of time and require several cleanings to be effective for the user.

In the embodiment shown, device 1 100 comprises control member 1 122 coupled to transverse member 1 120. Control member 1 122 is configured to move transverse member 1 120 away from elongated instrument 1200 (e.g. in a direction indicated by arrow 1 150) to allow viewing or another desired function from elongated instrument 1200. For example, after cleaning the surface of elongated instrument 1200 in the manner described above, a user can pull on control member 1122 to deflect intermediate member 1 115 away from the center of longitudinal member 1 110 such that elongated instrument 1200 is positioned past transverse member 1 120 and distal end 1112. This can allow elongated instrument 1200 to perform properly without interference from transverse member 1120.

Certain embodiments may also provide for liquid or surfactant delivery for cleaning elongated instrument 1200 or device 1100. In particular embodiments, specific components could be coated in a cleaning liquid, or absorb it for eventual distribution to scope upon contact. The cleaning liquid could be delivered around or next to device 1100 and could be a separate tube, or part of device 1100 in multi-lumen configuration.

Exemplar} embodiments also provide trocar (or other suitable guide) compatibility, e.g. via low-friction channels to guide, align, and constrain the ribbon member relative to distal cleaning tip. Certain embodiments could have one or multiple channels, and the channel(s) could be in addition to or part of the tubular configuration. In addition, the channel(s) could be included inside or be the natural internal channel between tubular member and the elongated instrument. The channel(s) could also include modifying the original tubular member - i.e. cut

{00662631} 41 section of the tube replacing that material with ribbon/tape, create additional channels comparably as needed, by removing tube material or stacking tape channel layers.

Other embodiments of the present disclosure may comprise a ribbon member, compressible member and a flexible transverse member, but do not require a control member to deflect the transverse member after cleaning. Referring to FIG. 10, for example, an embodiment is shown that is generally equivalent to the embodiment of FIG. 9. However, the embodiment of FIG. 10 does not include a control member to deflect intermediate member H I 5 and transverse member 1 120. Instead, transverse member 1120 comprises a split 1 129 that opens up and deflects transverse member 1120 as elongated instrument 1200 is advanced. In certain embodiments, tension can be maintained on ribbon member to assist in deflecting transverse member 1120. In certain embodiments, compressible member 1121 may also comprise a split 1128 that opens up and deflects as elongated instrument 1200 is advanced.

Still other embodiments may comprise a compressible member that extends around a portion of the device. Referring now to FIG. 11, an embodiment of device 1100 is similar to previously described embodiments. In this embodiment, however, compressible member 1121 is configured as an elastic and compressible ring that extends around intermediate member 1 1 15. In this embodiment, compressible member 1121 is configured as an O-ring, while in other embodiments, compressible member 1121 may be configured as a D-ring or other suitable shape in the embodiment shown compressible member 1121 comprises a guide 1131 (configured as a slit in tins embodiment) that is configured to retain ribbon member 1330 such that a first end 1331 of ribbon member 1330 can be pulled between elongated instrument 1200 and compressible member 1121 to remove matter from elongated instrument 1200. in certain embodiments, device 1100 can also comprise transverse member 1120 to assist in retaining compressible member 1121 as elongated instrument 1200 exerts a force on compressible member during cleaning in oilier embodiments, device 1100 may not comprise transverse

{00662631} 42 member 1120, and compressible member 1121 may be retained to device 1100 via the elasticity of compressible member 1 121. After cleaning, a second end 1332 of ribbon member 1330 can be pulled to deflect distal end 1 1 12 so that elongated instrument 1200 can perform viewing or other desired functions without obstruction.

Referring now to FIG. 12, a plurality of different configurations of different configurations of elastic and/or compressible members 1 121 configured as O-rings or D-rings are shown. In the illustrated embodiments, different thicknesses and slit configurations are shown.

Referring now to FIGS. 13-16, a side view of another embodiment of a device 1300 is shown during use cleaning an elongated instrument 1200. In the embodiment shown, device 1300 is configured to clean a surface of elongated instrument 1200 held within a cavity. Some aspects of device 1300 that are equivalent to previously described embodiments will not be repeated in this discussion.

In this embodiment, device 1300 comprises a longitudinal member 1310 with a tubular configuration comprising a proximal end 131 1 and a distal end 1312. Device 1300 also comprises a flexible transverse member 1320, as well as a compressible member 1321 and ribbon member 1330. In certain embodiments, longitudinal member 1310 and flexible transverse member 1320 may be formed from a unitary component, while in other embodiments, longitudinal member 1310 and flexible transverse member 1320 may be separate components. Longitudinal member 1310 comprises guides 1331 configured to guide ribbon

1330 across distal end 1312 of longitudinal member 1310. In the embodiment shown, guides

1331 are shown as slots configured to direct ribbon member 1331 in a direction generally parallel to flexible transverse member 1320. In other embodiments, guides 1331 may direct ribbon member in other directions, including for example, perpendicular to transverse member

1320.

{00662631} 43 During operation, ribbon member 1330 and compressible member 1321 can function in a manner generally equivalent to the previously described embodiment (e.g. ribbon member 1330 is pulled between elongated instrument 1200 and compressible member 1321 during cleaning). In FIG. 13, a distal end 1212 of elongated instrument 1200 is extended just past distal end 1312 of longitudinal member 1310, which extends around elongated instrument 1200 (e.g. elongated instrument 1200 is disposed within tubular longitudinal member 1310). In FIG. 13, distal end 1212 of elongated instrument 1200 has not been advanced sufficiently for ribbon member 1330 to engage compressible member 1321. In FIG. 14, distal end 1212 of elongated instrument 1200 has advanced within longitudinal member 1310 such that ribbon member 1330 is engaged with compressible member 1321. In FIG. 15, distal end 1212 of elongated instrument 1200 has advanced further such that ribbon member 1330 is engaged with compressible member 1321. Also in FIG. 15, compressible member 1321 is compressed such that compressible member 1321 exerts a force on ribbon member 1330 toward the distal end 1212 of elongated instrument 1200. Ribbon member 1330 can be translated across the distal end 1212 of elongated instrument 1200 while compressible member 1321 exerts a force on ribbon member 1330 toward distal end 1221 of elongated instrument 1200 to assist in maintaining contact between ribbon member 1330 and distal end 1212 of elongated instrument 1200. As previously described, this can improved the cleaning efficiency of ribbon member 1330, particularly if distal end 1212 is not completely flat.

Unlike the previous embodiment, after elongated instrument 12.00 is cleaned, a separate control member is not needed to deflect flexible transverse member 1320. instead a user can optionally reduce the tension on ribbon member 1330 and move distal end 1212 of elongated instrument 1200 past transverse member 1320 as shown in FIG. 16. When elongated instrument 1330 engages compressible member 1321 with sufficient force, flexible transverse member 1320 will deflect away from the center of longitudinal member 1310 such that the

{00662631} 44 elongated instrument is positioned past transverse member 1320 and distal end 1312. Without compressible member 1321 maintaining contact with ribbon member 1330, ribbon member 1330 can be disengaged from distal end 1212. This can allow the elongated instrument to perform properly without interference from transverse member 1320 or ribbon member 1330.

In certain embodiments, the ribbon member may be controlled by a mechanism that spools the ribbon member. Referring now' to FIG. 17, a device 1400 comprises a housing 1470 and a longitudinal member 1410 comprising a proximal end 141 1 and a distal end 1412. In the embodiment shown, device 1400 comprises a spool member 1480 with a ribbon member 1430 extending from spool member 1480 to distal end 1412. In addition, device 1400 comprises an advancement mechanism 1490 configured to rotate or advance ribbon member 1430 around spool member 1480 and to and from distal end 1412. Distal end 1412 of device 1400 may comprise additional features (e.g. a compressible member, guides for ribbon member 1430, etc.) as shown in other embodiments disclosed herein. In the embodiment shown, advancement mechanism 1490 is configured as a trigger mechanism, while in other embodiments advancement mechanism 1490 may be configured differently (e.g. a crank, thumbwheel, pinch button, etc.).

Still other embodiments may comprise a spiral relief (e.g. a cut or gap) at the distal end of a longitudinal member to provide a mechanism for the distal end to stretch and deflect away from the end of the elongated instrument during use. In addition, the spiral relief can provide rotation of the cleaning component during use and potentially provide improved coverage of the instrument surface. An embodiment of such a device 1500 is shown in perspective and section views in FIGS. 18 and 19, as well as during use in FIGS. 20 and 21. In the embodiment shown, device 1500 includes a longitudinal member 1510 with a proximal end 1511 and a distal end 1512, as well as a cleaning member 1521 coupled to distal end 1512. In addition, device 1500 comprises a spiral relief 1590 near distal end 1512. In certain embodiments, cleaning

{00662631} 45 member 1521 may be configured as a compressible member similar to previously described embodiments. In other embodiments, cleaning member 1521 may not be compressible but may be configured as a rigid element. In some embodiments, cleaning member 1521 may be an integral component of longitudinal member 1510. During use, an elongated instrument 1200 can engage compressible member 1521 to clean a surface of elongated instrument in a manner as previously described herein. As force is applied from elongated instrument 1200, spiral relief 1590 can begin to stretch as shown in FIG. 20. Spiral relief 1590 can be configured such that compressible member 1521 applies sufficient force against elongated instrument 1200 to clean a surface of elongated instrument 1200 as elongated instrument 1200 engages compressible member 1521.

Referring now to FIG. 21, as elongated instrument 1200 is advanced relative to distal end 1512, the amount of force exerted on compressible member 1521 is increased. This increase in force on compressible member 1521 causes distal end 1512 and compressible member 1521 to deflect away from the end of the elongated instrument 1200. Accordingly, elongated instrument 1200 can perform its desired function without interference from compressible member 1521. It is understood that features and aspects of the embodiment shown in FIGS. 18-21 can be combined with features and aspects of other embodiments shown herein. For example, a ribbon member may be combined with a spiral relief in certain embodiments.

All of the devices, systems and/or methods disclosed and claimed herein can be made and executed without undue experimentation in light of the present disclosure. While the devices, systems and methods of this invention have been described in terms of particular embodiments, it will be apparent to those of skill in the art that variations may be applied to

{00662631} 46 the devices, systems and/or methods in the steps or in the sequence of steps of the method described herein without departing from the concept, spirit and scope of the invention. All such similar substitutes and modifications apparent to those skilled in the art are deemed to be within the spirit, scope and concept of the invention as defined by the appended claims.
