Abstract

A tapered sleeve is provided that includes a hydrophilic coating on an inner surface. In use, the device is typically removed from sterile packaging and soaked to activate the lubricous properties of the coating. An implant (e.g., a pre-filled silicon breast implant) is introduced into a large end of the sleeve and extruded into a surgical pocket of minimal access incision size through a small-sized end of the device.

Description

    CROSS-RELATED APPLICATIONS
  • This application is a continuation of U.S. patent application Ser. No. 12/387,215, filed Apr. 29, 2009, which is fully incorporated herein by reference.
  • BACKGROUND
  • Silicone breast implants were re-approved in the United States in November 2006 after having been withdrawn from the market. Implant recipients cite safety, scarring, and “natural” look and feel to be the top three indicators in selecting between saline- and silicone-filled implants for breast augmentation. Given that the more natural look and feel offered by silicon is a pre-requisite for many patients, silicone implants have already achieved nearly 50% market share following their return to the market.
  • But because silicone implants are pre-filled (to alleviate leakage concerns) they have generally required larger access incisions than saline implants. Due to the possibility of visible scars associated with the larger incisions, some patients have remained apprehensive about selecting silicone implants.
  • An additional consideration that has thus-far weighed against silicone implant selection involves the amount of time required for insertion. Hand manipulation can be time consuming even a highly skilled surgical practitioner. The time spent has a direct bearing on the expense of the procedure.
  • The extent (and nature) of such manipulation also impacts the safety of the procedure. Stated plainly, the poking and pushing required to manually insert a prefilled silicone implant can be quite rough. Indeed, clinical studies have shown that the majority of silicone implant leaks/ruptures are attributable to sharp instrument damage and/or local stress forces exerted on the implant at the time of insertion.
  • Advances have been made in the construction methods and materials used in silicone breast implants over the last decade (e.g., the introduction of cohesive gels, textured shells, and anatomical shapes). However, little improvement has been made in the method of inserting the implants. That is, until use of the device described in U.S. patent application Ser. No. 12/228,072 to Keller.
  • The Keller filing describes a device and methods addressing each of the above-referenced issues. It discloses a specially-adapted pastry bag type device for implant introduction. The device enables silicon implant insertion though smaller incisions at dramatically reduced introduction time as compared to the common practice for silicon implant introduction. Likewise, the potential for implant damage has been significantly reduced. By addressing the cited delivery challenges through use of the Keller device, the popularity of silicon-based implants is poised to overtake that of saline-filed counterparts. This scenario is made more likely given ultimate market introduction of the Keller device with improvements as described herein.
  • SUMMARY
  • Like the original Keller device, the present invention comprises a truncated conical sleeve. The frustum-shaped device is adapted to receive a silicon breast implant and by squeezing the sleeve, expel the implant from its smaller end into a tissue pocket. The implant delivery sleeve is constructed of a flexible fabric and similar in size to store-bought pastry bags.
  • More specifically, since the size of silicone implants may vary in a range from about 150 cc to about 800 cc, the dimensions of the sleeve may vary. A proximal opening sized to fit any implant in this size range and a distal opening sized to fit the smallest implant may be desirable. The distal/tip opening then may be enlarged by trimming the sleeve to provide a larger opening. Indicia may be present on the exterior of sleeve as a guide for cutting to the proper dimensions.
  • In use, the small end of the delivery sleeve is placed through a skin incision into a tissue pocket and pressure is applied to force the implant from the sleeve into the pocket in use. Such action avoids rough or gross manipulation as required by manual implantation. As such, use of the sleeve makes for a more “gentle” procedure reducing the potential for implant damage and/or adjacent tissue trauma.
  • In addition, the small size of the delivery sleeve opening allows the physician flexibility in his/her surgical approach by allowing the access through the inframammary, periareolar, or axillary sites. In all cases, the incision is smaller and less noticeable than otherwise required for inserting silicone implants, thereby diminishing any scarring.
  • While similarly advantageous in regard to the above, the present invention incorporates additional features and advantages in use as compared to the Keller system.
  • For instance, the sleeve is advantageously constructed of rip-stop nylon fabric. In such construction, the fabric is advantageously between about ¾ to about 1½ oz weight material per sailmaker's yard. It may be as heavy 2¼ oz or heavier still by the same standard. To offer maximum translucency when wet-out (a feature useful for determining/confirming implant orientation within the sleeve), the fabric is preferably not pigmented. Other material options are possible as well, but the rip-stop nylon offers particular advantages in terms of durability and ease of handling, especially in connection with its use as further described below.
  • Other constructional features define another optional aspect of the present invention. Specifically, the device is advantageously cut from rip-stop nylon cloth that is adhered along an overlapping seam with double-sided tape. 3M, Inc. offers 5 mill transfer tape that is suitable for this purpose; suitable fabric may be obtained from Challenge Sailcloth, Inc. So-constructed, no binding of the fabric edges is required to prevent unraveling or other problems. Cost is utterly minimized, without any compromise in performance. Still, other constructional approaches may be employed without departing from other aspects of the present invention.
  • Regardless, the interior of the sleeve is packaged and supplied with a user-activated coating thereon. An example of such coating is hydrophilic coating. It is user-activated by soaking the sleeve in fluid (e.g., deionized water or sterile saline solution) as further described below. It is stably adhered to or bonded to the sleeve. A number of coatings and/or suppliers thereof may supply and/or apply the coating. A preferred vendor is AST Products, Inc. applying LUBRILAST hydrophilic coating and/or other coating(s) as described in U.S. Pat. Nos. 6,238,799 and 6,866,936 incorporated herein by reference in their entireties. Other suitable coatings can be applied as well to devices such as the device set forth in Keller U.S. patent application Ser. No. 12/228,072 filed on Dec. 7, 2007, and which is incorporated herein by reference.
  • So-coated, the interior of the sleeve becomes extremely slippery/lubricous when soaked. The lubricous coating adhered to the sleeve, then, controllably allows the silicone implant to be manipulated down and out of the tapered device into place by a squeezing/pushing motion. Preferably, such motion is applied to the sleeve proximal to the bulk of the implant. Delivering an implant by such action avoids damage to the implant and/or further fuss or fiddle in delivering a pre-filled implant, such as a silicone breast implant.
  • The construction of the sleeve facilitates preparing it for use in the manner described by allowing compaction of the sleeve into a basin (i.e., a disposable bowl or other undersized container—such as the implant packaging itself—as typically available in an operating room). Specifically, the foldable (vs. merely flexible) nature of the fabric and non-interfering seam provide advantages. These features allow the device to be easily folded, crumpled or otherwise compacted to fit into such a container and at least substantially submerged in fluid without continued manual effort and/or compression under another object to push or hold it down. Moreover, such action (the compaction) is accomplished without damage to the sleeve. Ideally, no significant trace of the sleeve manipulation is evident when the device is put to use. That does not mean that no visual evidence of the manipulation remains. Rather, no structural damage has occurred.
  • The coating may be applied to the subject device(s) in a number of ways. In one approach, if the end of the sleeve is open, it can be closed-off by an object (such as a ball) and the interior filled with coating fluid that is subsequently poured-out. In another approach, the exterior of the sleeve can be masked with a removable layer (e.g., adhered paper or tape) to avoid coating the outer surface when spraying or dip-coating. In another approach, the interior of the sleeve is blocked from receiving coating (e.g., by taping-off the ends of the sleeve with double-stick tape or otherwise) and only the exterior of the device is coated. After removing the tape (e.g.; by cutting-off the sealed/blocked ends), the sleeve is rolled-over/everted so that now only the interior surface is coated. In any case, it is desirable to avoid hydrophilic coating on the exterior of the finished device in order to permit better physician grip on the sleeve after its soaking.
  • The present invention includes such features as described above. Still further, it includes methods associated with and/or activities implicit to the use of the devices described.

  • FIGS. 2A and 2B illustrate manipulation of the sleeve;
  • FIG. 3A-3F illustrate preparatory acts in using the subject device;
  • FIGS. 4A-4D illustrate use of the present invention in a breast augmentation procedure;
  • FIGS. 5A-5D illustrate use of the present invention in an alternative surgical approach for breast augmentation.
  • Variation of the invention from the embodiments pictured is, of course, contemplated. Moreover, details commonly understood by those with skill in the art may be omitted.
  • DETAILED DESCRIPTION
  • FIG. 1 illustrates a pre-filled silicone implant 2 and sleeve 10 according to the present invention provided to facilitate implant delivery. Sleeve 10 has general conical shape that defines a first opening 12 at a larger end and a smaller opening 14 at a terminal end.
  • The tip of the device may include indica 16 coordinated to various implant sizes to facilitate trimming the opening to the correct size. The indica provide a guide for a practitioner to cut along a selected line in order to size the exit diameter of the device for a given implant in a size range, for example, of between about 150 cc to about 800 cc. By so-trimming the sleeve, exit diameters from between about 3 cm to about 6 cm are provided. For a more typical range of implant sizes, the openings may be sized approximately as follows (width dimension measured with the sleeve laid flat): 4.5 cm for 300 cc implants, 5.0 cm for 300 cc to 450 cc implants, and 5.5 cm for 450 cc to 550 cc implants.
  • Sleeve 10 is advantageously constructed with a seam 18 formed using double-sided tape to close overlapping edges 20, 22 of a cut sheet. Of course, other joining methods (e.g., ultrasonic welding), and/or constructional approaches may be employed.
  • Apart from such optional aspects, sleeve 10, necessarily includes a user-activated lubricious coating 24 adhered to the interior of the sleeve. So-coated, no introduction of further lubricant into the sleeve or over the surface of the implant is required for implant delivery. Instead coating 24 is stably adhered to the sleeve, and simply activated (e.g., by hydration) for use. Such a coating substantially mitigates or altogether eliminates risk associated with the introduction of additional foreign body material (in the form of applied lubricant) into the patient along with the implant.
  • Given that lubricant need not be applied to the surface of the implant and that the implant is neither directly manipulated during delivery nor introduced in such a way that it touches the recipient's skin, the implantation procedure may proceed as a “no touch” approach. Such an approach is advisable in avoiding capsular contracture.
  • Capsular contracture is an abnormal response of the immune system to foreign materials. The exact cause of contracture is not known. However, noted factors include bacterial contamination, silicone breast implant rupture or leakage, and hematoma. Methods which have reduced capsular contracture include limiting handling of the implants and skin contact prior to insertion as well as irrigation with triple-antibiotic solutions. Use of the present invention easily enables practicing these methods and further addresses the noted factors as a gentle, no-touch means of implant delivery.
  • As shown in FIGS. 2A and 2B, when an implant 2, such as a silicone implant, is set into sleeve 10, the sleeve can be manipulated to apply pressure to direct the implant along the length of the sleeve and toward distal opening 14. The flexible sleeve is conformed to the implant where there is slack in the material, and the implant to the sleeve where sleeve material is taut. The larger proximal opening 12 of the sleeve allows for implant introduction into the sleeve with little or substantially no digital force or manual manipulation.
  • With the implant set within the sleeve, the sleeve body 26 may be twisted closed. By any combination of such twisting and progressive compression action (such progression illustrated in transition from FIG. 2A to FIG. 2B) the surgeon is able to apply pressure via the sleeve to the implant and force it out of the delivery device and into a surgical pocket as illustrated in subsequent figures. Generally, a proximal hand 30 grip is used primarily to drive the implant forward, with the distal hand 32 grip more for offering stability and guidance to the end of the sleeve.
  • In addition, when introducing the implant into a surgical pocket, the pocket can be manipulated by a retractor to force the pocket open. Such action opens the void/space into which the implant is to be set, and may further help draw the implant inward by creating a partial vacuum. Moreover (although by no means necessary), the retractor may next be brought to bear on the sleeve to further assist the user's manipulation of the sleeve to extrude the implant into the surgical pocket.
  • FIGS. 3A-3F offer more detail regarding use of the subject delivery sleeve. Specifically, this series of figures illustrates the manner in which the sleeve and an implant are prepared. FIG. 3A shows each an implant 2 in its packaging 4, the sleeve 10 (removed from sterile packaging), scissors 40, and a basin 50 as typically found in a surgical suite. The basin is shown partially filled with saline 52 (optionally including antibiotic solution and/or Betadine®). To activate the lubricious coating inside the sleeve, the sleeve is folded or simply pushed into basin 50 in a compacted state as shown in FIG. 3B to soak. The sleeve preferably remains in fluid until time for use.
  • At least some of the fluid in the basin can be poured-off into the implant packaging container 4 as shown in FIG. 3C in order to bathe the implant in solution (especially useful if loaded with antibiotics) prior to implantation.
  • If trimming the sleeve end is desired in order to better fit a specific implant size, it may occur next as illustrated in FIG. 3D. However, sleeve 10 may be trimmed as soon as it is unpackaged. Alternatively, the delivery sleeve may be specifically sized and/or packaged in coordination with a given size of implant to avoid any such need.
  • FIG. 3E illustrates the sleeve 10 with an implant therein. Because of the translucent nature of the sleeve material, implant orientation can be visually confirmed as indicated in relation to the landmark offered by the tape seam 18. Prior to delivering the implant in a medical procedure, a test run may be performed as illustrated in FIG. 3F by running the implant through the sleeve. After which, the implant is re-loaded in the sleeve for implantation deployment. Performing such a test run offers a valuable fit check, especially when the sleeve end had been trimmed to accommodate larger-sized implants to ensure that the implant will push-out cleanly.
  • FIGS. 4A-4D illustrate use of the subject device in delivering an implant employing a transaxillary approach. An incision 60 is created in an axillary site leading to a subcutaneous pocket (not shown) under left breast 62. The pocket may be formed by employing various dissection techniques known to skilled practitioners. The access incision is shown held open by a small retractor 40. The pocket itself may be created in either the subglandular or subpectoral space. The submuscular plane tends to be less vascular, and is associated with fewer sensory alterations of the nipple areolar complex. So, a subpectoral pocket may be preferred.
  • In any case, FIG. 4B illustrates a larger Deaver retractor passing through incision 60 into the breast pocket. In addition, the distal tip of sleeve 10 is received within the incision. As shown in FIG. 4C, while the implant is squeezed forward along the sleeve, the retractor may be used to urge the surgical pocket open and/or bear down on the sleeve as described above.
  • FIG. 4D illustrates left breast 62 enlarged as desired. Once right breast 64 is similarly treated and symmetry confirmed (with any subsequent adjustments made), the breast pocket incisions are closed.
  • Note, prior to undertaking implant delivery, an inflatable sizer will typically be placed in the pocket under each breast. These sizer(s) may be placed to aid in prosthesis size selection, and can also be over-filled to provide intraoperative tissue expansion. FIG. 5A illustrates a first sizer emplaced using a periareolar approach (sizer fill tube 70 shown). With a second sizer in place, FIG. 5B shows the Deaver retractor inserted into the right breast 64 pocket and sleeve 10 being introduced into the incision. In doing so, the tip or distal end of the sleeve may be crimped or crumpled-down as shown to aid in passing through the incision.
  • Indeed, the same technique may be employed irrespective of access approach chosen. However, the technique may be more helpful or necessary for introduction into smaller incisions.
  • FIG. 5C illustrates implant extrusion into the breast pocket much as shown in FIG. 4C. A complete augmentation procedure (save final incision closure) in which both breasts 62 and 64 are filled is presented in FIG. 5D.
  • Regardless of the surgical approach taken, it has been found that the step of inserting a prefilled silicone implant can occur within a timeframe of about 5 to about 20 seconds employing the subject invention as compared to a time interval of up to 5 to 15 minutes for a traditional hand manipulation of the same implant. Additionally, because the implant can be inserted through a small opening, the size of the surgical incision can be made smaller than would otherwise be required for a silicone implant. Essentially, saline implant-size incisions can effectively be used to deliver pre-filled silicone implants.
  • Illustrative examples of such use under confidential clinical site conditions include:

  • Viewed otherwise, a larger silicone implant can be delivered for a given incision-size as will be appreciated by those with skill in the art. Such a consideration may be important especially when considering a periareolar approach as illustrated in FIGS. 5A-5D.
  • The periareolar approach may sometimes be preferred because the color of the areola can offer “camouflage” to help the incision scar blend in. The periareolar approach is often less surgically challenging than a transaxial approach. But since the size of the incision is coordinated with that of the areola in a periareolar approach, the size of pre-filled implant that could previously be inserted therethrough is sometimes limited. Use of the subject device relaxes this limitation, thereby offer each of the patient and surgeon more (often better) options.
  • The invention includes the methods set forth above in terms of method of manufacture, preparation and/or use. The methods may be performed using the subject devices and sometimes by other means.
  • The methods may include the act of providing a suitable device. Such provision may be performed by the end user. In other words, the act of “providing” merely requires that the end user access, approach, position, set-up, grasp or otherwise obtain the requisite device for the subject method. Methods recited herein may be carried out in any order of the recited events which is logically possible, as well as in the recited order of events.
  • Exemplary aspects of the invention, together with details regarding material selection and manufacture have been set forth above. As for other details of the present invention, these may be appreciated in connection with the above-referenced patents and publications as well as generally known or appreciated by those with skill in the art. The same may hold true with respect to method-based aspects of the invention in terms of additional acts as commonly or logically employed.
  • In addition, though the invention has been described in reference to several examples, optionally incorporating various features, the invention is not to be limited to that which is described or indicated as contemplated with respect to each variation of the invention. Various changes may be made to the invention described and equivalents (whether recited herein or not included for the sake of some brevity) may be substituted without departing from the true spirit and scope of the invention. In addition, where a range of values is provided, it is understood that every intervening value, between the upper and lower limit of that range and any other stated or intervening value in that stated range is encompassed within the invention.
