Abstract
Abstract A hernia patch has a first layer of inert synthetic mesh material selectively sized and shaped to extend across and beyond a hernia. A second layer of inert synthetic mesh material overlies the first layer to create a generally planar configuration for the patch. The first and second layers are joined together by a seam that defines a periphery of a pouch between the layers and provides stiffness to the patch for urging the patch to conform to the generally planar configuration across the hernia, which helps to prevent folding of the patch as the surgeon withdraws his or her finger. The seam may be straight, zig-zag, sinusoidal or other configurations that effectively urge the patch to conform to a planar configuration. One of the layers has a border that extends beyond the seam and that has a free outer edge. A plurality of border slits extend from the outer edge through the border substantially to the seam. An access slit is formed in one of the layers for insertion of a surgeon's finger into the pouch to facilitate insertion of the patch into the patient and to position the patch across the hernia.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
94 words
A tissue aperture repair patch for implanting within a patient, comprising: two layers of inert synthetic mesh material, at least one of said layers being sized and shaped to extend across and beyond a tissue aperture in a patient; a seam joining said layers that imparts stiffness to the patch for biasing the patch in a planar configuration; and at least one of said layers of inert synthetic mesh material having a periphery extending beyond said seam that defines a border having a free outer edge to fill uneven voids in a patient's tissue.
Claim 2
Dependent Claim
94 words
A tissue aperture repair patch for implanting within a patient, comprising: two layers of inert synthetic mesh material, at least one of said layers being sized and shaped to extend across and beyond a tissue aperture in a patient; a seam joining said layers that imparts stiffness to the patch for biasing the patch in a planar configuration; and at least one of said layers of inert synthetic mesh material having a periphery extending beyond said seam that defines a border having a free outer edge to fill uneven voids in a patient's tissue.
Claim 3
Dependent Claim
24 words
The patch according to claim 1 , wherein said layers of inert synthetic mesh material are ultrasonically joined to each other at said seam.
Claim 4
Dependent Claim
22 words
The patch according to claim 1 , wherein said seam is arranged in one of an oval, ovoid, loop or ring configuration.
Claim 5
Dependent Claim
22 words
The patch according to claim 1 , wherein said patch is configured in one of a circular, loop, ovoid, or oval shape.
Claim 6
Dependent Claim
14 words
The patch according to claim 1 , wherein said layers have the same size.
Claim 7
Dependent Claim
21 words
The patch according to claim 1 , wherein said seam is located approximately one centimeter inward from said free outer edge.
Claim 8
Dependent Claim
107 words
A tissue aperture repair patch for implanting in a patient, comprising: a first layer of inert synthetic mesh material sized and shaped to extend across and beyond a tissue aperture in a patient; a second layer of inert synthetic mesh material secured to the first layer by a seam to create a pouch between the first and second layers; an opening in the pouch for providing access to an interior of the pouch to position the patch across the tissue aperture; and the seam defining a periphery of said pouch between said layers, and imparting stiffness to the patch for biasing the patch into a planar configuration.
Claim 9
Dependent Claim
107 words
A tissue aperture repair patch for implanting in a patient, comprising: a first layer of inert synthetic mesh material sized and shaped to extend across and beyond a tissue aperture in a patient; a second layer of inert synthetic mesh material secured to the first layer by a seam to create a pouch between the first and second layers; an opening in the pouch for providing access to an interior of the pouch to position the patch across the tissue aperture; and the seam defining a periphery of said pouch between said layers, and imparting stiffness to the patch for biasing the patch into a planar configuration.
Claim 10
Dependent Claim
39 words
The patch according to claim 7 , wherein: the seam is spaced inwardly from a periphery of at least one of said first layer and said second layer, said seam defining a border between said seam and said periphery.
Claim 11
Dependent Claim
15 words
The patch according to claim 7 , wherein: said seam is in a zig-zag configuration.
Claim 12
Dependent Claim
149 words
A tissue aperture repair patch, comprising: a first layer of inert synthetic mesh material sized and shaped to extend across and beyond hernia; a second layer of inert synthetic mesh material overlying said first layer to create a generally planar configuration for the patch; said first layer and said second layer being joined together by a seam that defines a periphery of a pouch between said layers, said seam imparting stiffness to the patch for biasing the patch to a planar configuration; an opening in one of said layers for providing access to an interior of said pouch to facilitate insertion of the patch into the patient and to position the patch across the tissue aperture; and wherein the seam is spaced inwardly from a periphery of at least one of said first layer and said second layer, said seam defining a border between said seam and said periphery.
Claim 13
Dependent Claim
149 words
A tissue aperture repair patch, comprising: a first layer of inert synthetic mesh material sized and shaped to extend across and beyond hernia; a second layer of inert synthetic mesh material overlying said first layer to create a generally planar configuration for the patch; said first layer and said second layer being joined together by a seam that defines a periphery of a pouch between said layers, said seam imparting stiffness to the patch for biasing the patch to a planar configuration; an opening in one of said layers for providing access to an interior of said pouch to facilitate insertion of the patch into the patient and to position the patch across the tissue aperture; and wherein the seam is spaced inwardly from a periphery of at least one of said first layer and said second layer, said seam defining a border between said seam and said periphery.
Claim 14
Dependent Claim
15 words
The patch according to claim 10 , wherein: said seam is in a zig-zag configuration.
