A surgical buttress includes a body portion and a band disposed on each of the distal and proximal ends thereof. The surgical buttress is configured to attach to an end effector of a surgical stapling apparatus. The body portion, having perforations disposed thereon, overlies the working surface of one of the first or second jaws of the end effector. A resilient portion extends transversely beyond the side edges of the first or second jaws. Each band remains attached to the end effector following the firing thereof. The proximal band is removably attachable to a hook feature disposed on one of the first or second jaws of the end effector. The surgical buttress can be made from suitable degradable or non-degradable materials. One embodiment contemplates a detachable and disposable single use loading unit. A method of attaching the surgical buttress to a surgical apparatus is also envisioned.
1. A surgical buttress, comprising: an elongate body having a distal end, a proximal end, a first side edge, a second side edge, and a resilient peripheral portion which extends from at least one of the first and second side edges of the elongate body, the resilient peripheral portion configured as
1. A surgical buttress, comprising: an elongate body having a distal end, a proximal end, a first side edge, a second side edge, and a resilient peripheral portion which extends from at least one of the first and second side edges of the elongate body, the resilient peripheral portion configured as a resilient side skirt of the elongate body that can be resiliently pulled to engage sides of a stapler jaw; anda first side wall extending from the first side edge of the body, and a second side wall extending from the second side edge of the body. 2. The surgical buttress according to claim 1, further comprising: a first band secured to each of the first side edge and the second side edge of the body at the distal end of the body, the first band defining a first opening and being disposed at a transverse angle relative to a plane defined by the body; anda second band secured to each of the first side edge and the second side edge of the body at the proximal end of the body, the second band defining a second opening. 3. The surgical buttress according to claim 2, wherein the second band is disposed in the plane of the body. 4. The surgical buttress according to claim 2, wherein the first and second side walls are formed of a resilient material. 5. The surgical buttress according to claim 2, wherein at least one of the first and second openings have at least two different radii of curvature. 6. The surgical buttress according to claim 2, wherein the body includes a plurality of perforations. 7. The surgical buttress according to claim 2, wherein at least the body is made from degradable materials selected from the group comprising natural collagenous materials, cat gut, or synthetic resins including those derived from alkylene carbonates including trimethylene carbonate, tetramethylene carbonate; caprolactone, valerolactone, dioxanone, polyanhydrides, polyesters, polyacrylates, polymethylmethacrylates, polyurethanes, glycolic acid, lactic acid, glycolide, lactide, polyhydroxy butyrates, polyorthoester, polyhydroxy alkanoates, homopolymers thereof, and copolymers thereof. 8. The surgical buttress according to claim 2, wherein at least the body is made from non-degradable materials selected from the group comprising polyolefins, including polyethylene, polydimethylsiloxane, polypropylene, copolymers of polyethylene and polypropylene, and blends of polyethylene and polypropylene; ultra high molecular weight polyethylene, polyamides; polyesters including polyethylene terephthalate; polytetrafluoroethylene; polyether-esters including polybutester; polytetramethylene ether glycol; 1,4-butanediol; polyurethanes; and combinations thereof; silk; cotton, linen, and carbon fibers. 9. The surgical buttress according to claim 1, wherein the resilient peripheral portion has a resiliency, and wherein the resilient side skirt resiliently constricts the resilient peripheral portion against the stapler jaw to secure the surgical buttress to the stapler jaw. 10. A surgical buttress for use with a surgical stapling apparatus, the surgical buttress comprising: a body having a distal end, a proximal end, a first side edge, and a second side edge, the body configured and dimensioned to substantially overlie a portion of at least one of: fastener slots of a first jaw of an end effector of the surgical stapling apparatus; andfastener pockets of a second jaw of the end effector of the surgical stapling apparatus;a resilient peripheral wall extending from at least the first side edge of the body and the second side edge of the body, wherein the resilient peripheral wall has a resiliency;wherein the resilient peripheral wall is configured as resilient side skirts that can be resiliently pulled to engage sides of a stapler jaw of a surgical stapling apparatus, and wherein the resilient side skirt resiliently constricts the resilient peripheral wall against the stapler jaw to secure the surgical buttress to the stapler jaw. 11. The surgical buttress according to claim 10, further comprising: a first resilient band secured to each of the first side edge and the second side edge of the body at the distal end of the body, the first band defining a first opening and being disposed at a transverse angle relative to a plane defined by the body; anda second resilient band secured to each of the first side edge and the second side edge of the body at the proximal end of the body, the second band defining a second opening. 12. The surgical buttress according to claim 11, wherein the body includes a plurality of perforations. 13. The surgical buttress according to claim 11, wherein at least one of the first and second bands defines an opening having at least two different radii of curvature. 14. The surgical buttress according to claim 11, wherein the second resilient band is disposed in the plane of the body. 15. The surgical buttress according to claim 11, wherein at least the body is made from degradable materials selected from the group comprising natural collagenous materials, cat gut, or synthetic resins including those derived from alkylene carbonates including trimethylene carbonate, tetramethylene carbonate; caprolactone, valerolactone, dioxanone, polyanhydrides, polyesters, polyacrylates, polymethylmethacrylates, polyurethanes, glycolic acid, lactic acid, glycolide, lactide, polyhydroxy butyrates, polyorthoester, polyhydroxy alkanoates, homopolymers thereof, and copolymers thereof. 16. The surgical buttress according to claim 11, wherein at least the body is made from non-degradable materials selected from the group comprising polyolefins, including polyethylene, polydimethylsiloxane, polypropylene, copolymers of polyethylene and polypropylene, and blends of polyethylene and polypropylene; ultra high molecular weight polyethylene, polyamides; polyesters including polyethylene terephthalate; polytetrafluoroethylene; polyether-esters including polybutester; polytetramethylene ether glycol; 1,4-butanediol; polyurethanes; and combinations thereof; silk; cotton, linen, and carbon fibers.
