Abstract: An inguinal hernia prosthesis includes a cord locating structure that provides cord protecting functions. The cord locating structure, which may be a semi-circular or other shaped recess positioned along a longitudinal peripheral edge of the prosthesis, is designed to only surround a portion of the cord, e.g. less than 180 or preferably 120 degrees, with the remaining cord circumference being positioned by the element against appropriate muscle tissue. The cord locating structure may be referenced as a non-encircling lateral cord locating structure. The prosthetic: provides tension free repair; minimizes cord damage through tissue ingrowth/strangulation effects, inadvertent suturing through the cord structure, and abrasion with the prosthetic; and minimizes size of prosthetic used in the repair; and is configured to reconstitutes the pre-hernia muscle physiology.

Abstract: A variety of polymeric synthetic hernia mesh prosthesis with surface treatment on at least one tissue-facing surface to control tissue adhesion are disclosed including heparin surface treatment which provides heparin present in an amount to yield heparin bioactivity of at least one of i) an ATIII binding of at least 2 pmol/cm2, and ii) a thrombin deactivation of at least 0.2 IU/cm2; an acrylic surface treatment for coupling thereto of a heparin surface treatment, a collagen surface treatment or both; and an amino-functional polysiloxane surface treatment for coupling thereto of a heparin surface treatment. The synthetic hernia mesh may be formed of monofilament or multifilament polypropylene or polyester, and may be formed as a multi-layer prosthesis with an outer layer formed of a polymeric synthetic hernia mesh with surface treatment to control tissue adhesion coupled to one or more polymeric synthetic hernia meshes without such surface treatments.

Abstract: A prosthesis for repairing a tissue or muscle wall defect. The prosthesis comprises a layer of repair fabric having first and second and an edge that extends between the first and second surfaces. The prosthesis also includes a barrier that is inhibits the formation of adhesions with adjacent tissues and organs. The barrier may overlap a portion of the first and second surfaces. The barrier may be formed separate from and attached to the layer of repair fabric to permanently cover a portion of the edge. The repair fabric may be formed from a material which is susceptible to the formation of adhesions with sensitive tissue and organs. The cord protector may be formed from material which inhibits the formation of adhesions with sensitive tissue and organs. The barrier may overlie a portion of at least one of the first and second surfaces of the repair fabric.

Abstract: A compression anastomotic device for reconstruction of a tubular body lumen includes a pair of interconnectable open center compression rings or discs adapted to form a closed loop anastomotic ring in the reconstructed hollow lumen. The anastomotic ring defines an anastomotic plane, wherein the anastomotic ring is non-circular in plan view (i.e. within the plane), and wherein the compression rings or discs have a dimension greater in one direction within the anastomosis plane than in an orthogonal direction in the anastomosis plane, whereby the greater dimension defines a long axis for the compression rings or discs. The anastomotic apparatus may be passed through the body lumen with the long axis of the rings of the anastomotic device generally parallel with the axis of the tubular body lumen to ease the insertion or withdrawal of the device, and to provide a more naturally shaped anastomosis.

Abstract: Specifically, the anastomosis device of the present invention provides an anastomosis ring; such as but not limited to a ring of staples, in the form of an oval or ellipse. One specific embodiment of the present invention is a side to end anastomotic stapler with a row of staples formed in an elliptical pattern. Another embodiment of the present invention is a pair of anastomotic compression rings formed in an ellipse. A further embodiment of the invention is compression disc, rather than open ring structure.

Abstract: A suture-less, tension free, one-piece, double layer, inguinal hernia repair prosthetic is preferably formed of a single piece or sheet of repair fabric, such as polypropylene mesh, PTFE mesh, biologic material, or combinations thereof. The prosthetic sheet preferably includes a fold line dividing the sheet into two general halves. Each prosthetic half of the prosthetic sheet is preferably shaped generally to fit within the inguinal canal. Each prosthetic half of the sheet includes an opening in the inner portion of the sheet and a slit extending to the peripheral portion of the prosthetic half. The slits extend to generally opposite side of the prosthetic. Each opening is adapted to receive a patient's spermatic cord structure there through.

Abstract: A universal, surgical prosthesis for hernia repair is provided in the form of a foldable sheet. The prosthesis includes a barrier layer formed of a material adapted to prevent biological adherence thereto, such as polytetrafluoroethylene, and a second surface layer formed of a material adapted to promote biological tissue adherence thereto, such as polypropylene. The second surface may be formed of a series of spaced projections. The prosthesis is adapted to be manipulated into an operative position to exhibit an appropriate exterior when in the operative position. In this manner, the universal, surgical prosthesis can be utilized for a wide range of surgical procedures.

Abstract: A surgical clamp allows for mobilization of an organ or hollow viscus of a patient during a surgical procedure with minimization of trauma to the organ or hollow viscus. The surgical clamp includes at least one handle adapted to be gripped by the user for manipulation of the surgical clamp and the engaged organ or hollow viscus, and at least on jaw attached to the handle, wherein the jaw is adapted to substantially encircle the engaged organ or hollow viscus of the patient. The clamp may be sized to fit through a conventional trocar such that the surgical procedure may be a laparoscopic procedure for operating on the organ or hollow viscus, such as the bowel.

Abstract: A prosthesis and a method for repairing a tissue or muscle wall defect, such as an inguinal hernia, near a cord-like structure, such as the spermatic cord. The prosthesis comprises a layer of repair fabric having a cord opening therethrough that is adapted to receive the cord-like structure when the prosthesis is implanted at the repair site. The prosthesis also includes a cord protector that is attachable to the repair fabric at the opening to isolate the cord-like structure from the fabric in proximity to the opening. The repair fabric may be formed from a material which is susceptible to the formation of adhesions with sensitive tissue and organs. The cord protector may be formed from material which inhibits the formation of adhesions with sensitive tissue and organs. The cord protector may overlie a portion of at least one of the first and second surfaces of the repair fabric.

Abstract: A circular stapler for side to end, side to side or end to side anastomosis includes an actuating head portion attached to an elongated tubular body with a handle on the opposed end of the body from the head. The head includes an anvil and associated stapling mechanism, wherein the anvil and the associated stapling mechanism are positioned perpendicular to a longitudinal axis of the head. The anvil is releasably attached to the head and may be attached to the head through an anvil applicator. The anvil may include an extendable stem.

Abstract: An intestinal intraluminal reconstruction and resection device includes a mechanism for intussusception of the bowel, a bowel anastomosis mechanism and a mechanism for severing the resected bowel. The surgical device allows the user to carry out intraluminally an anastomosis first, prior to resection of the intestine or any hollow viscus, therefore not exposing the dirty intraluminal content to the clean abdominal or thoracic cavities. The above is achieved by first intussuscepting the hollow viscus, then anastomosis and finally intraluminal resection.

Straps are attached to the side edges of the blank for connecting the one-piece surgical mask and cap to the user. The upper portion of the blank above the eye opening forms the cap portion, and the lower portion of the blank below the eye opening forms the mask portion. Elastic bands may be provided surrounding the eye opening to further secure the one-piece surgical mask and cap of the present invention to the user.
