Implantable prosthesis
First Claim
1. An implantable prosthesis for repairing a defect in a muscle or tissue wall, the prosthesis comprising:
- a seamless preformed flexible body having a three-dimensional contoured shape and comprising a first end, a second end opposite the first end, and a perimeter incorporating the first end and the second end;
wherein the preformed flexible body independently assumes the contoured shape, the contoured shape comprisingan open sided bowl at the first end of the preformed flexible body;
a substantially planar area at the second end of the preformed flexible body; and
a transitional area coupling the open sided bowl of the first end with the substantially planar area of the second end, the transitional area comprising an arch region coupled with a curved and banked region; and
wherein, following along the perimeter, the arch region leads to the open sided bowl which leads to the curved and banked region which leads to the substantially planar area which leads to the arch region, thereby completing the perimeter, wherein rigidity of the preformed flexible body is substantially uniform throughout.

Abstract
An implantable prosthesis can have a three-dimensional shape that is invertible, so as to assume either a right configuration or a left configuration, which can be substantially mirror images of each other, so as to eliminate the need for separately manufacturing a left prosthesis and a right prosthesis. An implantable prosthesis can be preformed to independently assume a contoured three-dimensional shape that more adequately fits the extraperitoneal laparoscopic inguinal space, while simultaneously maintaining a relatively large area for fixation of the prostheses (e.g., through suturing or integration with the surrounding tissue). An implantable prosthesis can have a three-dimensional contoured shape that is formed from a single piece of continuous material, such as a mesh, and can possess substantially uniform rigidity. An implantable prosthesis may be trimmed, cut, or altered at an outer perimeter with no detrimental effect on its ability to independently maintain a predetermined three-dimensional contoured shape.

17. An implantable prosthesis for repairing a defect in a muscle or tissue wall, the prosthesis comprising:
a preformed body configured to independently assume a predetermined three-dimensional contoured shape, the preformed body comprising a single, seamless, and continuous piece of mesh having strands forming intersections; a coating disposed at least partially within the intersections of the strands of the mesh; and an inner portion and a perimeter surrounding the inner portion, wherein rigidity of the perimeter is substantially uniform. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. An implantable prosthesis for repairing a defect in a muscle or tissue wall, the prosthesis comprising:
a preformed flexible body comprising a single, continuous piece of preformed coated mesh, wherein the preformed flexible body is configured to independently assume a predetermined three-dimensional contoured shape that possesses no sharp point, the shape comprising a substantially planar area; and one or more non-uniform curvatures deviating away from the substantially planar area; wherein the preformed flexible body is invertible between a left orientation and a right orientation, the left orientation and the right orientation being substantially mirror images of each other, and wherein the preformed coated mesh comprises coated strands forming a plurality of intersections, and wherein the three-dimensional contoured shape is maintained by interaction of the plurality of intersections with each other imparting structure to form and maintain the three-dimensional contoured shape. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

46. A method for fabricating an implantable prosthesis for repairing a defect in a muscle or tissue wall, the method comprising:
-
providing a coating to a single piece of mesh comprising strands forming a plurality of intersections, such that the coating is disposed at least partially within the intersections of the mesh; curing the coating on the mesh at one or more predetermined temperatures for one or more predetermined times; providing a template having a predetermined shape; placing the mesh in the template; heating the mesh in the template at one or more predetermined temperatures for one or more predetermined times so that the mesh retains the predetermined shape, thereby forming the implantable prosthesis; and removing the implantable prosthesis from the template, wherein the implantable prosthesis comprises a preformed flexible body comprising a single, continuous piece of preformed coated mesh, wherein the preformed flexible body is configured to independently assume a predetermined three-dimensional contoured shape that possesses no sharp point, the shape comprising a substantially planar area; and one or more non-uniform curvatures deviating away from the substantially planar area; wherein the preformed flexible body is invertible between a left orientation and a right orientation, wherein the left orientation and the right orientation are substantially mirror images of each other, and wherein the preformed coated mesh comprises strands forming a plurality of intersections, and wherein the three-dimensional contoured shape is maintained by interaction of the plurality of intersections with each other imparting structure to form and maintain the three-dimensional contoured shape. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53)
