REINFORCING INCISION DRAPES HAVING STITCHING ZONES BOUNDED BY REINFORCING ZONES FOR CLOSING INCISIONS FORMED IN FRAGILE TISSUE

Abstract

A reinforcing incision drape for tissue, such as fragile tissue, includes an absorbable surgical mesh having top and bottom major surfaces. The absorbable surgical mesh has a stitching zone and first and second reinforcing zones that bound opposite sides of the stitching zone. The stitching zone is less porous and the first and second reinforcing zones are more porous than the stitching zone. A releasable liner covers the top major surface of the absorbable surgical mesh within the stitching zone of the absorbable surgical mesh. A weaker adhesive, such as a pressure sensitive adhesive, covers the bottom major surface of the surgical mesh within the centrally located stitching zone of the absorbable surgical mesh, and a stronger adhesive, such as cyanoacrylite, covers the first and second reinforcing zones of the absorbable surgical mesh.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0062] Referring to FIG. 1A, in one embodiment, fragile tissue 100, such as subcutaneous fragile tissue, may be prepared for a surgical procedure by applying a layer of a tissue adhesive 102 over an exposed surface of the fragile tissue 100.

[0063] Referring to FIG. 1B, in one embodiment, after the layer of tissue adhesive 102 has been applied to the exposed surface of the fragile tissue 100, a reinforcing incision drape 104 may be positioned on top of the tissue adhesive layer 102. The reinforcing incision drape may be a surgical mesh that is absorbable or non-absorbable.

[0064] Referring to FIG. 1C, in one embodiment, a tool 108, such as a prod or rod, may be used for unfurling and/or smoothing out the reinforcing incision drape 104 over the surface of the fragile tissue 100. The tool 108 may also be used to press the reinforcing incision drape 104 into the adhesive tissue layer 102 (FIG. 1B) previously applied to the exposed surface of the fragile tissue 100. In one embodiment, additional tissue adhesive may be applied to the top surface of the deployed reinforcing incision drape 104 to further insure a stable attachment of the reinforcing incision drape to the exposed surface of the fragile tissue 100. In one embodiment, the reinforcing incision drape 104 is porous to allow the additional tissue adhesive to pass therethrough. In one embodiment, the tissue adhesive is initially in liquid form so that it may pass through the drape and hardens as it cures. In one embodiment, the tissue adhesive is allowed to cure and/or harden for reliably securing the reinforcing incision drape 104 in place over the exposed surface of the fragile tissue 100.

[0065] Referring to FIG. 1D, in one embodiment, a cutting tool 110 having a sharpened cutting blade 112, such as a scalpel, is utilized for creating a surgical incision 114 through the reinforcing incision drape 104, the tissue adhesive layer 102 (FIG. 1B), and the fragile tissue 100. After the surgical incision 114 has been formed, a surgical procedure may be conducted through the wound formed by the incision 114.

[0066] Referring to FIG. 1E, in one embodiment, after a surgical procedure has been completed, a surgical fastening element, such as a suture 116, may be utilized for closing the incision 114 to approximate the opposing edges of the fragile tissue 100 lying on opposite sides of the incision 114, and the opposing cut edges of the reinforcing incision drape 104. The suture 116 is desirably passed through the reinforcing incision drape 104 located on both sides of the incision 114 formed in the reinforcing incision drape for drawing together both the opposing edges of the reinforcing incision drape 104 and the opposing edges of the fragile tissue 100.

[0067] In one embodiment, the surgical closure element may be a suture, an absorbable or non-absorbable suture, a barbed suture, surgical staples, and/or surgical adhesives.

[0068] Referring to FIG. 1F, in one embodiment, the suture 116 preferably passes through the reinforcing incision drape 104 and into the fragile tissue 100 for approximating the opposing edges of the fragile tissue at the incision line 114. In one embodiment, the suture 116, the reinforcing incision drape 104, and the tissue adhesive layer 102 (FIG. 1B) are absorbable so that the components do not have to be removed from a patient after healing of the wound created by the incision 114. The reinforcing incision drape 104 supports the fragile tissue during suturing and healing so that the fragile tissue is not torn by the suture 116.

[0069] Referring to FIG. 2, in one embodiment, a reinforcing incision drape 202, such as an absorbable, porous surgical mesh, has an outer perimeter 205 that is sized to cover a surgical site located on fragile tissue 200. In one embodiment, the reinforcing incision drape 202 is positioned atop the fragile tissue 200 prior to making an incision in the fragile tissue. In one embodiment, the reinforcing incision drape 202 is positioned directly on an exposed surface of the fragile tissue 200. The reinforcing incision drape 202 may include a porous mesh having a polymerization initiator disposed on the mesh. In one embodiment, the reinforcing incision drape 202 has a pressure sensitive adhesive (PSA) on a wound-facing side of the reinforcing incision drape 202. The PSA is preferably used for initial placement of the drape on the fragile tissue. In one embodiment, after initial placement, the reinforcing incision drape may be attached to the fragile tissue 200 using a second, stronger adhesive (e.g., a rapidly cross-linking adhesive such as cyanoacrylate) to form a reinforced incision drape 202 prior to forming an incision.

[0070] In one embodiment, an incision 214 may be created through the reinforcing incision drape 202 and into the fragile tissue 200. After a surgical procedure has been completed through the incision 214, surgical sutures 216 may be applied directly through the reinforcing incision drape 202 that remains attached to the fragile tissue 200. The surgical sutures 216 preferably approximate and/or draw the opposing edges of the cut fragile tissue 200 together, and also desirably draw the opposing cut edges of the reinforcing incision drape 202 together for closing the wound formed by the incision 214. In one embodiment, the reinforcing incision drape 202 is absorbable and is absorbed by a patient's body during and/or after healing of the incision 214. In one embodiment, the suture material 216 is also absorbable. In one embodiment, the pressure sensitive adhesive and the second, stronger adhesive used to more reliably secure the reinforcing incision drape 202 to the fragile tissue 200 is also absorbable.

[0071] Referring to FIG. 3A, in one embodiment, a reinforcing incision drape 302, such as a porous, absorbable surgical mesh, preferably includes a centrally located stitching zone 320 that is bounded on both sides by first and second reinforcing zones 322A, 322B. The stitching zone 320 is adapted to accommodate an incision 314 formed through the reinforcing incision drape 302. The central stitching zone 320 may have different structural properties than the reinforcing zones 322A, 322B. For example, the central stitching zone may be less porous or less rugged than the reinforcing zones 322A, 322B. In one embodiment, the stitching zone 320 desirably includes a pressure sensitive adhesive on a wound-facing face of the reinforcing incision drape 302. In one embodiment, the reinforcing zones 322A, 322B may also include a pressure sensitive adhesive on the wound-facing face of the reinforcing incision drape 302.

[0072] In one embodiment, the reinforcing incision drape 302 preferably includes a plurality of pores extending through the reinforcing incision drape that desirably enable medical personnel to have visibility through the drape for observing an underlying incision and/or the tissue surrounding a planned incision. In one embodiment, the plurality of openings that extend through the reinforcing incision drape preferably enable an adhesive to be passed through the openings for forming a strong bond between the reinforcing incision drape and the underlying fragile tissue. In one embodiment, the porous openings are located within the first and second reinforcing zones 322A, 322B, and the stitching zone 320 may be less porous or non-porous. In one embodiment, the porous openings are located within the first and second reinforcing zones 322A, 322B and not within the stitching zone 320. In one embodiment, the porous openings within the first and second reinforcing zones 322A, 322B are larger than the porous openings in the stitching zone 320. In one embodiment, the openings or pores in the surgical mesh have a diameter of about 1 mm.

[0073] In one embodiment, the reinforcing incision drape may be a surgical mesh. In one embodiment, the surgical mesh may be a polypropylene mesh. In one embodiment, the surgical mesh may include a substantially flat monofilament polypropylene mesh with reinforcement filaments. The length of the reinforcing incision drape may vary depending upon surgical needs.

[0074] In one embodiment, prior to making an incision, the bottom surface of the reinforcing incision drape may be positioned against the fragile tissue of a patient. The bottom surface may have a slight or weak adhesive layer (e.g., a pressure sensitive adhesive) applied thereto for forming a non-permanent and/or repositionable frictional engagement between the reinforcing incision drape and the fragile tissue. Due to the slight or weak adhesive layer, if an initial positioning of the reinforcing incision drape on a patients fragile tissue is not acceptable (e.g. misaligned), the reinforcing incision drape 302 may be lifted or peeled away from the patients fragile tissue for re-positioning. Once medical personnel are satisfied that the reinforcing incision drape has been properly positioned and/or aligned atop the fragile tissue (e.g. properly aligned with a surgical site where an incision will be made), a stronger adhesive, such as a clear or translucent adhesive may be applied over the top surface of the reinforcing incision drape for passing through the plurality of openings (e.g., pores) to more permanently and/or more firmly affix the reinforcing incision drape to the fragile tissue. In one embodiment, the clear or translucent adhesive preferably includes tissue glue such as Cyanoacrylate.

[0075] In one embodiment, a reinforcing incision drape may be wound into a roll for shipment and storage. In one embodiment, after a surgeon determines a length of an incision required for a surgical procedure, the surgeon may unwind the roll and cut a section of the roll to provide a section of reinforcing incision drape having a desired length. In one embodiment, medical personnel may unwind a section of the reinforcing incision guide onto a flat support surface. In one embodiment, when the reinforcing incision drape has been unwound, a cutting instrument may be used for cutting the reinforcing incision drape to a desired length. In one embodiment, a plurality of reinforcing incision drapes having different sizes, dimensions and/or lengths may be provided to medical personnel. In one embodiment, medical personnel may select one of the reinforcing incision drapes having the proper size, length and/or width that suit the particular surgical needs of a patient. In one embodiment, a plurality of reinforcing incision drapes having different sizes, lengths and/or widths may be provided, and a surgeon may cut or trim a selected one of the plurality of drapes to suit surgical requirements.

[0076] In one embodiment, the pressure sensitive adhesive enables the reinforcing incision drape 302 to be initially positioned over a surface of fragile tissue. If a surgeon determines that the reinforcing incision drape 302 is not properly positioned over the fragile tissue, the pressure sensitive adhesive enables the reinforcing incision drape to be removed from the surface of the fragile tissue and re-positioned over the fragile tissue. In one embodiment, after a surgeon is satisfied that the reinforcing incision drape has been properly positioned over the fragile tissue, a stronger and/or more rugged second adhesive may be used to more permanently secure the reinforcing incision drape 302 to the fragile tissue. In one embodiment, the stronger adhesive is applied to the reinforcing zones 322A and 322B of the reinforcing incision drape 302 and is not applied to the stitching zone 320 of the reinforcing incision drape 302.

[0077] Referring to FIG. 3B, in one embodiment, after the reinforcing incision drape 302 has been positioned over a surgical site on the fragile tissue 300, an outer perimeter 305 of the reinforcing incision drape 302 desirably surrounds an area where the incision 314 is to be formed. The stitching zone 320 of the reinforcing incision drape 302 is desirably aligned with and bounds the incision 314.

[0078] In one embodiment, the stitching zone 320 is secured to the fragile tissue 300 using only a pressure sensitive adhesive provided on the tissue facing face of the reinforcing incision drape. In one embodiment, the reinforcing zones 322A, 322B also include a pressure sensitive adhesive for adhering the reinforcing incision drape 302 to the fragile tissue. In one embodiment, additional adhesive is applied over the reinforcing zones 322A, 322B of the reinforcing incision drape 302. In one embodiment, the additional adhesive preferably passes through pores provided in the reinforcing zones 322A, 322B for forming a stronger bond between the reinforcing zones 322A, 322B and the fragile tissue 300. In one embodiment, the stitching zone 320 portion of the reinforcing incision drape 302 is less porous than the reinforcing zones 322A, 322B of the reinforcing incision drape 302. In one embodiment, the stitching zone 320 does not include any of the stronger, second adhesive used to bond the reinforcing zones 322A, 322B to the fragile tissue 300.

[0079] In one embodiment, a cutting tool, such as a scalpel, may be used for forming an incision 314 in the stitching zone 320 of the reinforcing incision drape 302. The incision 314 preferably extends into the fragile tissue 300 for enabling a surgical procedure to be performed through the incision 314. In one embodiment, at the conclusion of a surgical procedure through the incision 314, a surgical suture 316 may be utilized for closing the incision 314 in the fragile tissue 100 and approximating the cut opposing edges of the reinforcing incision drape 302.

[0080] Referring to FIG. 4, in one embodiment, a reinforcing incision drape 402 preferably includes an absorbable, porous surgical mesh having an outer perimeter 405 that is adapted to bound a surgical site that has been identified on fragile tissue. In one embodiment, the reinforcing incision drape 402 preferably includes a central stitching zone 420 and two outer reinforcing zones 422A, 422B that bound opposite sides of the central stitching zone 420. The central stitching zone may extend along the length of the reinforcing incision drape 402. In one embodiment, a removable liner 430 preferably overlies a top surface of the central stitching zone 420, whereby the top surface of the stitching zone faces away from a wound-facing side of the reinforcing incision drape 402.

[0081] In one embodiment, the reinforcing incision drape 402 preferably includes pressure sensitive adhesive applied over the wound-facing side of the reinforcing incision drape 402.

[0082] In one embodiment, after the reinforcing incision drape 402 is positioned over the fragile tissue and with the removable liner 430 in place over the top surface of the stitching zone, a second, stronger liquid adhesive may be applied to the top surface of the reinforcing incision drape 402 that faces away from the fragile tissue. The stronger liquid adhesive preferably passes through the pores located in the reinforcing zones 422A, 422B of the reinforcing incision drape 402. The releasable liner 430 acts as a mask to prevent the stronger liquid adhesive from contacting the stitching zone 420 of the reinforcing incision drape 402. In one embodiment, after the stronger liquid adhesive applied to the reinforcing zones 422A, 422B has cured and/or hardened, the releasable liner 430 may be removed for exposing the top surface of the stitching zone 420. An incision may be formed in the stitching zone 420 of the reinforcing incision drape for making a surgical opening in the fragile tissue. At the conclusion of a surgical procedure, the incision may be closed using surgical closing components, such as surgical sutures.

[0083] Referring to FIG. 5, in one embodiment, a reinforcing incision drape 502 is desirably adapted to cover a surgical site on a surface of fragile tissue. In one embodiment, the reinforcing incision drape 502 has an outer perimeter 505 that is adapted to bound a surgical site on the fragile tissue. The reinforcing incision drape 502 may be made of a porous surgical mesh. In one embodiment, the reinforcing incision drape 502 desirably has a central stitching zone 520 and first and second reinforcing zones 522A, 522B that are located on opposite sides of the central stitching zone 520. The central stitching zone 520 and the first and second reinforcing zones 522A, 522B preferably extend along the length L.sub.1 of the reinforcing incision drape 502. In one embodiment, the reinforcing incision drape 502 includes a releasable liner 530 that preferably extends over top surface of the central stitching zone 520, the top surface of the stitching zone facing away from the wound-facing side of the reinforcing incision drape. In one embodiment, the releasable liner 530 has laterally extending strips 535A, 535B that extend laterally from a central section 533 to lateral side edges 545, 555 of the drape 502. In one embodiment, the spaced sections of first reinforcing zone 522A are preferably exposed between the first laterally extending strips 535A, and spaced sections of the second reinforcing zone 522B are preferably exposed between the second laterally extending strips 535B.

[0084] In one embodiment, after the reinforcing incision drape 502 has been initially positioned over the fragile tissue, a liquid adhesive may be applied to the exposed surface areas of the reinforcing incision drape 502 that are not covered by the releasable liner 530. The liquid adhesive desirably passes through the pores in the first and second reinforcing zones 522A, 522B that are not covered by the respective laterally extending strips 535A, 535B. The stronger liquid adhesive that passes through the exposed pores is desirably cured for strongly adhering the first and second reinforcing zones 522A, 522B to the exposed surface of the fragile tissue. After the stronger adhesive has cured, the releasable liner 530 including the laterally extending strips 535A, 535B may be removed from the exposed top surface of the reinforcing incision drape 502.

[0085] In one embodiment, an incision 514 may be made in the reinforcing incision drape 502. The incision 514 preferably extends along the length of the central stitching zone 520 of the reinforcing incision drape for providing access to a surgical site within the fragile tissue. The incision 514 preferably extends into the fragile tissue. After a surgical procedure has been completed, a closure element such as surgical sutures may be used for closing the incision 514 formed in the stitching zone 520 and the fragile tissue.

[0086] Referring to FIG. 6A, in one embodiment, a reinforcing incision drape 602 preferably has an outer perimeter 605 that defines a length and a width of the reinforcing incision drape. In one embodiment, the reinforcing incision drape 602 preferably includes a porous surgical mesh having pores extending between a top surface and a bottom surface of the surgical mesh. In one embodiment, the surgical mesh may be absorbable. In one embodiment, a bottom major face of the surgical mesh includes a pressure sensitive adhesive that enables the reinforcing incision drape 602 to be releasably secured to the tissue. In one embodiment, the pores formed in the surgical mesh enable an adhesive, such as a liquid adhesive, to pass through the pores for forming a stronger, more permanent bond between the reinforcing incision drape 602 and the underlying fragile tissue.

[0087] In one embodiment, the reinforcing incision drape 602 desirably includes a central stitching zone 620 that is bounded by first and second reinforcing zones 622A, 622B. In one embodiment, the reinforcing incision drape 602 desirably includes a releasable liner 630 having a central section 633 that preferably overlies and extends along the length of the central stitching zone 620 and first and second laterally extending strips 635A, 635B that extend outwardly from opposite sides of the central section 633 of the releasable liner 630.

[0088] In one embodiment, the reinforcing incision drape 602 desirably has relatively large openings 640 (i.e., larger than the pores) that are initially covered by the laterally extending strips 635A, 635B of the releasable liner 630. In one embodiment, the laterally extending strips 635A, 635B of the releasable liner 630 cover the relatively large openings 640. In one embodiment, the first laterally extending strips 635A of the releasable liner are spaced from one another so that at least some of the pores in the first reinforcing zone 622A of the reinforcing incision drape 602 are exposed between the first laterally extending strips 635A. In one embodiment, the second laterally extending strips 635B are spaced from one another so that at least some of the pores in the second reinforcing zone 622B of the reinforcing incision drape 602 are exposed between the second laterally extending strips 635B.

[0089] In one embodiment, after the tissue-facing surface of the reinforcing incision drape 602 is positioned over fragile tissue, and with the releasable liner 630 in place over the top surface of the reinforcing incision drape 602, a liquid adhesive 625 (FIG. 6B) may be applied over a top surface of the reinforcing incision drape 602. The liquid adhesive desirably passes through the exposed porous sections of the first and second reinforcing zones 622A, 622B that lie between the respective first and second laterally extending strips 635A, 635B.

[0090] Referring to FIGS. 6A and 6B, in one embodiment, after the liquid adhesive 625 cures, the releasable liner 630 including the laterally extending strips 635A, 635B may be removed from the top surface of the reinforcing incision drape 602. After the liner 630 has been removed, the central stitching zone 620 and the openings 640 previously covered by the first and second laterally extending strips 635A, 635B are exposed. The cured adhesive 625 extends over the first and second reinforcing zones 622A, 622B and between the opening 640 and the areas previously covered by the laterally extending strips 635A, 635B (FIG. 6A). An incision 614 may be created in the stitching zone 620 of the reinforcing incision drape 602 and into fragile tissue underlying the reinforcing incision drape. At the conclusion of a surgical procedure, the incision in the fragile tissue and the reinforcing incision drape may be closed using a tissue closing component such as sutures, absorbable sutures, tacks, staples and/or tissue adhesive. The reinforced incision drape preferably supports the fragile tissue during suturing and healing for preventing the fragile tissue from being damaged by the sutures.

[0091] While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, which is only limited by the scope of the claims that follow. For example, the present invention contemplates that any of the features shown in any of the embodiments described herein, or incorporated by reference herein, may be incorporated with any of the features shown in any of the other embodiments described herein, or incorporated by reference herein, and still fall within the scope of the present invention.
