Definitions

  • the present invention provides a medical device which can employed in a minimally invasive medical procedure, e.g., by deploying it in a blood vessel through a catheter. While a variety of such medical devices can be made in accordance with the invention, the invention is particularly useful as a filter for use in a blood vessel or other channel in a patient's body.
  • Filters can be deployed in channels or vessels in patient's bodies in a variety of medical procedures or in treating certain conditions. For example, rotating burrs are used in removing atheroma from the lumen of patients' blood vessels. These burrs can effectively dislodge the atheroma, but the dislodged material will simply float downstream with the flow of blood through the vessel. Filters can be used to capture such dislodged material before it is allowed to drift too far downstream, possibly occluding blood flow through a more narrow vessel.
  • this trap is optimally carried on a mandrel 260 further enhances its utility as most common angioplasty balloons and atherectomy devices are used in conjunction with such mandrels. While this trap is very useful and shows great promise in many common procedures, it may be possible to improve the ease with which it may be deployed and/or retracted.
  • occlusion devices can be used to occlude an arterial vessel or a septal defect. Some of these occlusion devices may radially expand into an enlarged configuration wherein they substantially fill the lumen of the vessel or extend over the margins on either side of a septal defect.
  • the friction between the occlusion device and the wall of the catheter can make it difficult to deploy the device at a precisely selected location.
  • the present invention provides a medical device which can easily be deployed and retracted during a minimally invasive medical procedure.
  • the medical device may take the form of a filter useful in any channel of a patient's body, be it in a blood vessel, urinary tract, or other type of vessel.
  • One embodiment of the invention provides a collapsible medical device including a mandrel and a functional element of any desired shape to achieve a particular end.
  • the mandrel has a distal end and a stop spaced proximally of the distal end.
  • a proximal length of the mandrel extends proximally of the stop and a distal length of the mandrel extends distally of the stop.
  • the functional element includes a radially expandable body having a proximal slider and a distal slider.
  • the proximal slider is slidably carried along the proximal length of the mandrel and the distal slider is slidably carried along the distal length of the mandrel.
  • the proximal and distal sliders are slidable along the mandrel independently of one another such that the distance between the proximal slider and the distal slider can be varied to effect different configurations of the functional element.
  • a medical device in accordance with another embodiment of the invention includes a mandrel and a suitably shaped functional element.
  • this mandrel has a distal end and a stop spaced proximally of the distal end.
  • a proximal length of the mandrel extends proximally of the stop and a distal length of the mandrel extends distally of the stop.
  • the functional element of this embodiment has a radially expandable body having a radially expanded configuration and adapted to resiliently assume the radially expanded configuration in the absence of a countervailing biasing force.
  • the radially expandable body is attached to the mandrel by a proximal slider and a distal slider.
  • the proximal slider is slidably carried along the proximal length of the mandrel and the distal slider is slidably carried along the distal length of the mandrel.
  • the proximal and distal sliders are slidable along the mandrel independently of one another such that the distance between the proximal and distal sliders can be varied to effect different configurations of the body.
  • the medical device has a mandrel generally as described above and also includes a functional element.
  • the functional element of this embodiment is formed of a resilient tubular braid which has a preferred radially expanded configuration but will assume a radially reduced profile upon axial elongation.
  • Proximal and distal sliders are attached to the tubular braid with a length of the braid extending therebetween.
  • the proximal slider is slidably carried along the proximal length of the mandrel and the distal slider is slidably carried along the distal length of the mandrel.
  • the proximal and distal sliders are slidable along the mandrel independently of one another.
  • Yet another embodiment of the invention provides a filter system which may be temporarily deployed in a channel of a patient's body.
  • This device includes a mandrel having a distal end and an enlarged diameter stop carried proximally of the distal end.
  • a filter is formed of a resilient tubular braid and includes proximal and distal sliders.
  • the proximal slider is slidably carried along the mandrel proximally of the stop and the distal slider is carried along the mandrel between the stop and the distal end of the mandrel.
  • the filter has a collapsed configuration wherein the sliders are spaced from one another a first distance along the mandrel and the filter has a first diameter.
  • the filter also has an expanded configuration wherein the sliders are spaced a second, shorter distance along the mandrel and the filter has a second diameter.
  • the filter's first diameter is less than its second diameter.
  • the present invention also contemplates a method of employing a medical device in a lumen vessel.
  • This medical device desirably comprises a mandrel having a distal end and a stop spaced proximally of the distal end. It also includes a functional element, which may be formed of a resilient tubular braid and include proximal and distal sliders, with the proximal slider being slidably carried along the mandrel proximally of the stop and the distal slider being carried along the mandrel between the stop and the distal end of the mandrel. The distal end of the mandrel is inserted in the lumen of the vessel.
  • the functional element is urged distally along the lumen to a treatment site by urging the mandrel distally such that the stop engages the distal slider and exerts a distal biasing force thereon.
  • This distal biasing force acts against a restorative force of the functional element to axially elongate the functional element and reduce friction between the functional element and a wall of the vessel.

  • This medical device comprises a filter system 10 which can be deployed in a channel in a patient's body.
  • this filter can be used in any channel in a patient's body, including blood vessels, the urinary tract or biliary tract and airways.
  • This filter system 10 is optimally designed to be deployed in a patient's vessel in a minimally invasive procedure, such as by introducing the filter system into a blood vessel through an introducing catheter (not shown in FIGS. 1 and 2).
  • the filter system 10 of the invention generally includes a mandrel 20 and a filter 50 .
  • the mandrel 20 can be thought of as having a primary function of positioning and controlling the deployment of the filter 50 while the filter can be considered the primary therapeutic or functional element of the system 10 .
  • the mandrel 20 should be fairly flexible to allow the device to be deployed in a curving body passageway without kinking or otherwise inhibiting suitable deployment of the filter 50 .
  • the mandrel can be formed of any material having any dimension suitable for the task for which the filter system 10 is to be employed, in most circumstances, the mandrel 20 will comprise an elongate metal wire.
  • the mandrel 20 is formed of nitinol, a roughly stoichiometric alloy of nickel and titanium having excellent “superelastic” properties.
  • the use of nitinol in medical guidewires and related applications is well known in the art and need not be discussed in detail here.
  • the distal-most length of the mandrel may include a flexible helically wound coil 22 extending thereover. The use of such helical coils to enhance flexibility of the distal tip is well known in the guidewire art.
  • the mandrel 20 has an enlarged diameter stop 40 attached thereto.
  • the stop 40 is spaced proximally from the distal tip 25 of the mandrel 20 .
  • the stop 40 is spaced proximally of the proximal end of the helical coil 22 of the mandrel. This permits the distal slider 60 of the filter 50 to slide relatively freely and unencumbered along the length of the mandrel distally of the stop.
  • the stop 40 can be formed of any desired material and can be attached to the mandrel 20 in any desired fashion.
  • the stop should be attached to the mandrel relatively securely, though, as the stop will be used to urge the filter 50 within the lumen of the vessel in which the system 10 is to be deployed.
  • the stop 40 may comprise a standard radiopaque marker band which has been securely crimped on the mandrel 20 and/or attached to the mandrel using an adhesive or solder.
  • the precise length and shape of the stop 40 is not critical.
  • the drawings illustrate the stop 40 as a relatively short cylindrical body attached about the circumference of the mandrel. However, the stop 40 may have a more bulbous shape and could, in theory, even be formed integrally with the mandrel.
  • the stop 40 effectively divides the mandrel into distal and proximal lengths.
  • the distal length 30 of the mandrel can be thought of as that length which extends distally from the stop 40 to the distal tip 25 of the mandrel.
  • the proximal portion 35 of the mandrel 20 can be thought of as comprising the length of the mandrel extending proximally from the stop 40 to the proximal end of the mandrel.
  • the filter 50 shown in FIGS. 1 - 5 has an elongate, generally tubular body 52 which extends from a distal slider 60 proximally to a proximal slider 65 .
  • the body 52 of the filter can be formed of any material suitable for the application at hand.
  • the filter body 52 typically comprises a length of a braided tubular fabric.
  • the use of a tubular braid of nitinol to make medical devices is described in some detail in International Publication No. WO 96/01591, the teachings of which were incorporated above by reference.
  • this process can employ a tubular braid of a fabric comprising two sets of nitinol wires wrapped helically about a mandrel, with one set of wires being wrapped spirally about the mandrel in one direction and the other set being wrapped in the other direction.
  • This braid is then placed in contact with a molding surface of a molding element which defines the shape of the desired functional element.
  • the body 52 of the filter 50 desirably is made of a fairly flexible, resilient material.
  • the filter 52 desirably has a radially expanded configuration, e.g., the shape shown in FIGS. 1 - 3 , which the device will tend to resiliently assume in the absence of any countervailing biasing force.
  • a body 52 formed of a nitinol tubular braid which has been heat set into the desired shape should suit this purpose well.
  • the body 52 of the filter 50 assumes a generally tubular shape having tapered proximal and distal ends.
  • the outer diameter of the generally cylindrical middle length of the body 52 should be sized to substantially fill the lumen of a vessel to ensure that the filter will effectively trap any emboli which may be entrained in the patient's bloodstream.
  • FIGS. 7 and 8 an alternative configuration of a filter body 152 is illustrated in FIGS. 7 and 8 and medical devices intended to achieve different clinical objectives are shown in FIGS. 11 and 13.
  • FIGS. 7 and 8 an alternative configuration of a filter body 152 is illustrated in FIGS. 7 and 8 and medical devices intended to achieve different clinical objectives are shown in FIGS. 11 and 13.
  • a variety of other filter shapes, as well as shapes of other types of medical devices should be readily apparent to one of ordinary skill in the art in light of the present teachings.
  • the filter 50 is attached to or carried by the mandrel 20 by means of a proximal slider 65 attached to the body 52 adjacent its proximal end and a distal slider 60 attached adjacent the distal end of the body 52 .
  • the distal slider 60 should be free to slide along at least a proximal portion of the distal length 30 of the mandrel while the proximal slider 65 should be free to slide along at least a distal portion of the proximal length 35 of the mandrel.
  • the stop 40 of the mandrel effectively defines a limit on the range of motion of these sliders 60 , 65 .
  • each of the sliders 60 , 65 should be slidable along its respective length of the mandrel, the sliders can take any desired shape.
  • each slider comprises a relatively thin ring which is carried about the mandrel.
  • the thin ring can be attached to the body 52 in any desired fashion, such as by crimping or swaging the fabric of the body between two layers of the ring or soldering, welding or otherwise adhering the fabric to the ring.
  • the structure of one suitable distal slider is schematically illustrated in a more detailed cross section in FIG. 6.
  • the proximal slider may have substantially the same configuration, but is not shown in this view simply for purposes of clarity.
  • the distal slider 60 comprises a relatively rigid annular ring 61 having an inner component 61 a and an outer component 61 b .
  • One or both components of the ring 61 is preferably formed of a radiopaque material to enable a physician to better visualize the position of the slider 60 during a procedure.
  • the inner component 61 a of the ring is received within the outer component 61 b and defines an annular space therebetween.
  • the inner diameter of the inner component is larger than the outer diameter of the mandrel 20 to facilitate sliding of the ring 61 with respect thereto.
  • Movement of the slider 60 with respect to the mandrel can be further facilitated by coating one or both of the inner surface of the inner component 61 a and the outer surface of the mandrel 20 with a friction-reducing coating, such as Teflon or a lubricious hydrophilic coating.
  • a friction-reducing coating such as Teflon or a lubricious hydrophilic coating.
  • a distal length of the fabric of the body 52 is received in the annular space between the interior and exterior components 61 a and 61 b of the ring.
  • the fabric is held in place in this space in any suitable manner, e.g. by means of a suitable solder or adhesive or by crimping the fabric between the inner and outer components.
  • FIG. 6 schematically illustrates both approaches, with the fabric being frictionally grasped between the two components of the ring 61 and held in place by a weldment or adhesive connection 62 at the distal end of the ring.
  • FIGS. 3 - 5 schematically illustrate the filter system 10 of FIGS. 1 and 2 in partial cross section.
  • the filter 50 is shown in cross section while the mandrel 20 and its components are shown in side view. This is intended to better illustrate the interaction of the stop 40 of the mandrel and the sliders 60 , 65 of the filter 50 .
  • the filter 50 is shown in its radially expanded configuration, which it will tend to assume in the absence of any countervailing biasing force.
  • the stop 40 of the mandrel is positioned within the body 52 of the filter and is not exerting any biasing force on either of the sliders 60 , 65 .
  • the mandrel 20 can be moved proximally and distally with respect to the filter 50 without substantially affecting the shape or position of the filter.
  • the limits of this range of free movement of the mandrel with respect to the filter are generally defined by the relationship between the stop 40 and the sliders 60 , 65 .
  • the mandrel can be moved from a distal position wherein the stop 40 abuts but does not exert any force on the distal slider 60 and a proximal position wherein the stop 40 abuts, but does not exert any significant force on, the proximal slider 65 .
  • the filter 50 (or any other functional element which is carried by the mandrel) to be fairly precisely positioned within a patient's vessel and retain that position even if the guidewire is moved slightly during use. This can be advantageous in circumstances where other devices are exchanged over the guidewire (e.g., during angioplasty and atherectomy procedures).
  • the inner diameter of the generally annular collars defining the sliders 60 , 65 is desirably larger than the outer diameter of the mandrel, as mentioned above. However, the inner diameter of these sliders should be smaller than the outer diameter of the stop 40 . In this fashion, the stop serves to limit movement of the sliders. As a consequence, the stop 40 serves as an effective limit on proximal movement of the distal slider 60 and distal movement of the proximal slider 65 . Apart from this relationship with the slider 40 and the fact that both sliders are indirectly linked to one another by the body 52 of the filter, the proximal and distal sliders are slidable along the mandrel essentially independently of one another.
  • FIGS. 4 and 5 The advantage of this arrangement is illustrated in FIGS. 4 and 5.
  • the mandrel 20 is being urged distally (to the left in this view, as illustrated by the arrow) and urges distally against the distal slider 60 .
  • the filter would travel with the mandrel without any appreciable alteration in the shape of the body 52 . In most clinical applications, though, this is not the case. Instead, there is typically some force restraining completely free movement of the filter within the channel of the patient's body. As schematically shown in FIG.
  • the body 52 of the filter may resiliently expand into physical contact with the interior surface of the vessel V. This contact with the vessel wall will tend to hold the filter 50 in place as the stop of the mandrel slides proximally and distally between the two sliders 60 , 65 .
  • the mandrel is urged distally until it exerts a distal force against the distal slider 60 (as shown in FIG. 4), this force will tend to axially elongate the body 52 .
  • FIG. 5 is similar to FIG. 4, but schematically illustrates what happens upon proximal retraction of the mandrel.
  • the stop 40 of the mandrel abuts against and exerts a proximal biasing force on, the proximal slider 65 of the filter 50 .
  • this proximal biasing force will act against the restorative force of the body 52 to axially elongate and radially reduce that body. This permits the device to be withdrawn proximally along the lumen of the vessel either for repositioning at a more proximal location or for withdrawal from the patient's body at the end of the procedure.
  • the proximal and distal sliders 60 , 65 are free to move relatively independently of one another, limited primarily by their indirect link to one another through the body 52 of the filter.
  • the proximal slider will slide proximally along the proximal length 35 of the mandrel.
  • the distal slider will be free to drift distally along the distal length 30 of the mandrel.
  • FIGS. 3 - 5 Another salient aspect of the device highlighted in FIGS. 3 - 5 is that the spacing between the sliders 60 and 65 changes in response to the mandrel acting against one of the sliders. Looking first at FIG. 3, the proximal and distal sliders are spaced a first distance from one another, with the body 52 engaging the wall of the vessel. When the stop 40 of the mandrel urges against one of the sliders, though, the body 52 will tend to axially elongate and the distance between the two sliders will increase.
  • FIG. 9 schematically shows the device of FIGS. 1 - 5 being deployed through a catheter C.
  • a length of the mandrel 20 and the entirety of the filter 50 is received within the lumen of the catheter C.
  • the mandrel 20 is being urged distally to exit the distal end of the catheter C.
  • the stop 40 is exerting a distal biasing force against the distal slider 60 within the relatively close confines of the catheter C.
  • the body 52 of the filter 50 will exert an outward force against the interior surface of the catheter C, increasing friction between the filter and the catheter C.
  • FIG. 10 schematically illustrates retrieval of the device of FIGS. 1 - 5 and 9 which has already been deployed in a patient's vessel.
  • the filter 50 is being withdrawn proximally into the lumen of the catheter C. This can be initiated by positioning the distal end of the catheter C just proximal of the proximal slider 65 and then moving the catheter C with respect to the stop 40 . This can be accomplished either by urging the catheter C distally or withdrawing the mandrel 20 proximally, as the operator sees fit at the time.
  • the catheter C will frictionally engage and will tend to radially compress the body 52 of the filter.
  • the slider 65 will be brought in contact with the stop 40 . Further movement of the catheter C with respect to the mandrel will urge more of the length of the body 52 into the lumen of the catheter C.
  • the distal slider 60 may slide distally along the distal length 30 of the mandrel, permitting the body 52 to axially elongate in response to the radial compression induced by the catheter C.
  • the body 52 of the filter will axially elongate and radially reduce in response to movement of the mandrel 20 with respect to the catheter C.
  • the stop 40 urges distally against the distal slider 60 , effectively pushing the filter 50 distally along the catheter C.
  • the stop 40 can be seen as pushing proximally on the proximal slider 65 . Again, this biasing force will tend to axially elongate and radially reduce the body 52 of the filter. This axial elongation and radial reduction of the body 52 in FIGS.
  • FIGS. 7 and 8 illustrate an alternative embodiment of the invention.
  • FIGS. 1 - 6 refer to a filter system 10 having a mandrel 20
  • FIGS. 7 and 8 show a filter system 110 having a mandrel 120 .
  • the primary difference between the filter 150 of FIGS. 7 and 8 and the filter 50 of FIGS. 1 - 6 is the shape of the filter in its fully radially expanded configuration.
  • the filter 50 has a generally tubular body with spaced-apart tapered ends.
  • the filter 150 of FIGS. 7 and 8 has a generally umbrella-shaped body 152 , with a proximal length of the fabric defining the body being inverted and received within the interior of the distal portion of the fabric.
  • the distal slider 160 and proximal slider 165 are positioned much more closely to one another in the fully deployed filter 150 , shown in FIG. 7, than are the spacers 60 , 65 in the fully deployed filter 50 , shown in FIGS. 1 - 3 .
  • FIG. 8 illustrates the filter 150 in an axially elongated, radially reduced state induced by withdrawing the mandrel 120 proximally.
  • the stop 140 will abut and urge proximally against the proximal slider 165 .
  • this tends to axially elongate the body 52 of that filter 50 without any substantial change in the shape of the filter.
  • the filter 150 of FIGS. 7 and 8 is more complex in its fully deployed, expanded state (shown in FIG. 7). Rather than simply axially elongating and radially reducing the shape shown in FIG.
  • the proximal length of the fabric which is received within the interior of the distal portion of the fabric will tend to evert.
  • the distal portion of the fabric i.e., the outer portion of the fabric shown in FIG. 7 will tend to remain in place in frictional engagement with the wall of the vessel during this process.
  • the shape of the interior surface of the umbrella will change first without any significant change in the external shape.
  • the body 152 will take on a shape which looks more like the shape of the filter 50 of the previous embodiment.
  • proximal slider 165 will further elongate the body until it reaches a shape such as that schematically illustrated in FIG. 8. This makes withdrawal of the trap easier, but care should be taken to ensure that any particular material retained within the interior of the umbrella-like body 152 is not inadvertently dumped back into the patient's bloodstream. This can be done, for example, by breaking down trapped thrombus using clot-busting drugs or by aspirating the particulate material through a catheter before proximally withdrawing the mandrel 120 .
  • a catheter C is urged distally along the proximal length 135 of the mandrel until the distal tip of the catheter (not shown in FIGS. 7 and 8) is positioned in the interior of the umbrella-like filter body 152 . If necessary, any particulate material within that interior can be aspirated through the catheter C and out of the patient's body. Thereafter, the mandrel can be withdrawn proximally, drawing the proximal slider 165 into the interior of the catheter C. As discussed above in connection with FIG. 10, this will help collapse the body 152 of the filter into the lumen of the catheter C.
  • the catheter C can be held in the same position while the rest of the filter 150 is drawn inside.
  • the catheter C and the mandrel can be withdrawn together as a unit a short distance so that the distal tip of the catheter C is positioned slightly proximal of the proximal edge of the deployed filter shown in FIG. 7. This will further facilitate drawing the body 152 down into the lumen of the catheter C.
  • the catheter, the filter and the mandrel 120 can be withdrawn together as a unit from the patient's body.
  • FIG. 11 shows a medical device which is similar to the embodiment shown in FIGS. 1 - 5 , 9 and 10 .
  • the shape of the body 52 ′ of the plug 50 ′ has a significantly different shape from the body 52 of the filter 50 discussed above. Whereas the majority of the length of the filter 50 would assume a relatively constant diameter if left unconstrained, the body 52 ′ of the plug 50 ′ has a more complex shape. While this device can also be used to filter fluid which is passing through a vessel, its design is particularly well-suited to occlude a vessel either temporarily or permanently.
  • a method for making and using a vascular occlusion device having a shape similar to that of the body 52 ′ of FIG. 11 is disclosed in International Publication No. WO 96/01591, the teachings of which were incorporated above. Briefly, though, this body 52 ′ includes a pair of spaced-apart enlarged diameter sections separated by a central section having a reduced diameter. If so desired, the surface of this device may be coated with a thrombogenic agent or nylon fibers or the like can be attached to the body 52 ′. Conversely, if the plug 50 ′ or the filter 50 are to be used solely for purposes of filtering fluids passing therethrough and it is preferred that any blood passing through the functional element not clot thereon, the body can be coated with an anti-thrombogenic agent.
  • withdrawing the mandrel 20 proximally will exert a proximal biasing force on the proximal slider 65 , facilitating withdrawal of the device into the deployment catheter, much as discussed above in connection with FIG. 10.
  • the catheter can be repositioned and the plug can be deployed distally out of the catheter again at the new location.
  • the plug 50 ′ of FIG. 11 can be used as a temporary occlusion device and withdrawn at the end of a procedure or treatment course. In other circumstances, though, it may be preferred to more permanently occlude the channel in which the plug 50 ′ is deployed. While the stop 40 abutting against the sliders 60 , 65 facilitates deployment and repositioning, the attachment of the stop 40 to the mandrel 20 could effectively prevent one from removing the mandrel from the plug.
  • the mandrel 20 can be withdrawn either partially or entirely from the plug in a variety of different manners.
  • the proximal portion 35 of the mandrel can be releasably attached to the stop 40 , e.g., by means of a threaded engagement therebetween.
  • the distal section 30 Without somehow locking the distal section 30 against rotation (e.g., by a splined connection between the distal section 30 and the distal slider 60 ), though, it can be difficult to disconnect these parts from one another.
  • FIG. 12 illustrates one preferred embodiment of a stop 40 ′ which may be used to withdraw the mandrel 20 while leaving the filter 50 or plug 50 ′ in place in the patient's body.
  • the stop 40 and the proximal slider 65 were both essentially annular in shape, with the relatively constant outer diameter of the stop being greater than the relatively constant inner diameter of the slider. As a consequence, one cannot readily withdraw the stop 40 from within the enclosure of the body 52 of the filter 50 .
  • the stop 40 ′ of FIG. 12 can be withdrawn from the interior of a filter 50 , plug 50 ′ or other device having a suitably adapted proximal slider.
  • the stop 40 ′ includes an external thread 42 ′ which extends spirally outwardly from the main body 44 ′ of the stop.
  • the proximal slider (not shown in this view) has a threaded internal surface which is sized and shaped to mate with the outer thread 42 ′ on the stop 40 ′. Aside from the spiral slot or keyway shaped to receive the thread 42 ′ of the stop, the inner diameter of the proximal slider should be slightly greater than the outer diameter of the body 44 ′ of the stop but less than the maximum diameter of the stop including the thread 42 ′. During normal operation, this will ensure that the stop 40 ′ will abut against the proximal slider so the device will operate as described above.
  • the mandrel can be withdrawn from the filter or plug by pulling the mandrel proximally until the stop 40 lightly abuts the proximal slider. Rotating the mandrel about its axis will permit the thread 42 ′ to travel along the slot in the proximal slider. In this manner, the stop can be withdrawn through the proximal slider and the mandrel can be completely removed from the patient's body, leaving the medical device in place within the vessel.
  • the present invention also contemplates a method of employing a medical device in a channel in a patient's body.
  • a medical device for the sake of convenience, the following discussion will make reference to FIG. 1- 5 and the reference numbers used therein. It should be understood, though, that this method can be used with any of a wide variety of medical devices having different functional elements (including the plug 50 ′ and the drainage catheter 250 illustrated in other drawings) and need not be limited to a filter system 10 having a filter 50 as its functional element.
  • the medical device is introduced into a vessel in a patient's body.
  • this would comprise inserting the distal end 25 of the mandrel 20 into the lumen of the patient's vessel V. This may be done either directly or, more commonly, by using an introducer sheath. Such introducer sheaths are commonly used in introducing medical devices for minimally invasive procedures.
  • the mandrel can be urged distally to introduce the functional element, i.e., filter 50 in FIGS. 1 - 5 , and to the vessel, as well.
  • the same tendency of the filter body 52 to axially elongate and radially reduce discussed above in connection with FIG. 4 will also reduce friction between the filter body 52 and the interior surface of the introducer sheath as the filter is advanced therealong.
  • the filter 50 may be urged distally along the lumen of the vessel V to a predetermined treatment site.
  • the treatment site may, for example, simply be a convenient location in a patient's vasculature positioned distally of an obstruction which will be treated with an angioplasty balloon or an atherectomy device.
  • the filter 50 can be advanced along the vessel by urging the mandrel distally such that the stop 40 engages the distal slider 60 .
  • This exerts a distal biasing force on the distal slider which, in turn, acts against a restorative force of the body 52 of the filter.
  • the body 52 will tend to axially elongate and take on a radially reduced profile. This reduces friction between the filter 50 and the wall of the vessel, facilitating advancement therealong.
  • the axial force against the mandrel can simply be released. This will permit the body 52 to expand radially and axially contract, drawing the two sliders 60 , 65 toward one another along the mandrel. If it is determined that the filter is not precisely positioned in the desired treatment site, it can be readily repositioned by pushing the mandrel distally or withdrawing it proximally and again allowing the filter to self-expand radially and self-contract axially once the mandrel stops acting against the sliders.
  • the operator can simply pull proximally on the mandrel to radially contract the device and facilitate proximal movement within the vessel, as shown in FIG. 5.
  • a catheter may be positioned adjacent a treatment site in a patient's body. This can be done in any desired fashion.
  • the mandrel 20 and the catheter can be advanced simultaneously through the patient's vessel.
  • the catheter will be positioned at the desired treatment site before the mandrel 20 is inserted into the catheter. This permits the operator to steer the catheter into place without hindrance from the mandrel or to track the catheter over a guidewire if the desired treatment site is positioned in a narrower or more tortuous vessel, after which the guidewire can be removed.
  • the distal tip 25 of the mandrel can be inserted into the proximal end (not shown) of the catheter outside the patient's body.
  • the catheter will frictionally engage the body 52 of the filter. Further distal urging of the mandrel will cause the stop 40 to exert a distal biasing force on the distal slider 60 .
  • this distal biasing force will tend to axially elongate and radially reduce the body 52 , further facilitating entry of the body into the lumen of the catheter.
  • the filter 50 may continue to be urged distally along the length of the catheter.
  • the distal urging of the stop 40 against the distal slider 60 will axially elongate and radially reduce the body, reducing friction between the body and the catheter during such advancement.
  • the mandrel can be urged distally until the device exits the distal end of the catheter.
  • the body will then tend to radially self-expand until it reaches a radially-expanded shape wherein it may engage the walls of the vessel (B in FIG. 9).
  • the distal tip of the catheter may be positioned distally of the desired treatment site.
  • advancement of the mandrel can be stopped when the operator determines by means of the radiopaque sliders 60 , 65 that the filter is in the desired treatment site.
  • the catheter can be withdrawn proximally while holding the mandrel 20 in place.
  • the body will tend to radially self-expand with the distal slider 60 remaining in substantially the same place due to its abutment against the stop 40 .
  • the mandrel be withdrawn from the patient's body either in part or in its entirety.
  • the distal most of those lengths can be detached from one another, leaving the filter 50 and the distalmost length in the patient's body while withdrawing the proximal-most length.
  • These lengths can be connected in any fashion known in the art, such as by means of a threaded engagement or by means of a solder which can be melted or softened by application of electrical resistance heating of the mandrel.
  • the entire mandrel 20 is withdrawn from the patient's body. This can be done by withdrawing the stop 40 through the proximal slider 65 of the filter.
  • One suitable stop 40 ′ is shown in FIG. 12. This stop 40 ′, used in conjunction with a specially adapted proximal slider (not shown, but described above) can be used to withdraw the stop through the proximal slider for removal of the mandrel. As explained previously, this can be accomplished by bringing the stop 40 ′ into abutting engagement with the proximal slider then rotating the mandrel 20 about its axis.
  • the filter 50 can be withdrawn into the lumen of the catheter C either by holding the mandrel stationary and advancing the catheter distally over the filter 50 or by holding the catheter in a fixed position and withdrawing the mandrel 20 proximally.
  • the proximal urging of the stop 40 against the proximal slider 65 tends to axially elongate and radially reduce the body 52 , both facilitating entry of the body 52 into the lumen of the catheter and reducing friction between the catheter and the length of the body 52 which is already received therein.
