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. The pouch houses a stiffening layer to provide stiffness to the patch for urging the patch to conform to the generally planar configuration across the hernia as the surgeon withdraws his or her finger. An access slit is formed in one of the layers for insertion of a surgeon's finger or instrument into the pouch to allow the surgeon to facilitate insertion of the patch into the patient and to position the patch across the hernia.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
83 words
A tissue aperture repair patch for implanting within 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, the first layer having a planar configuration, being resilient and having a selected stiffness; and a resilient stiffening layer of inert synthetic material carried by and overlying the first layer for supporting the first layer in the planar configuration, the stiffening layer having a greater stiffness than the first layer.
Claim 2
Dependent Claim
83 words
A tissue aperture repair patch for implanting within 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, the first layer having a planar configuration, being resilient and having a selected stiffness; and a resilient stiffening layer of inert synthetic material carried by and overlying the first layer for supporting the first layer in the planar configuration, the stiffening layer having a greater stiffness than the first layer.
Claim 3
Dependent Claim
34 words
The tissue aperture repair patch according to claim 1 further comprising a second layer joined to the first layer, said first layer and said second layer defining a pouch that encapsulates the stiffening layer.
Claim 4
Dependent Claim
36 words
A patch according to claim 2 , further comprising: a slit in one of said first and said second layers for insertion of a finger into said pouch to position the patch across the tissue aperture.
Claim 5
Dependent Claim
21 words
The patch according to claim 1 , wherein the first layer has an outer periphery that extends beyond the stiffening layer.
Claim 6
Dependent Claim
29 words
The patch according to claim 1 , wherein a slit is in the first layer, and the first layer has an outer periphery that extends beyond the stiffening layer.
Claim 7
Dependent Claim
123 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 to create a pouch between the first and second layers; an opening in the pouch for insertion of a finger into the pouch to position the patch across the tissue aperture; and a resilient stiffening layer within said pouch for supporting the first layer and the second layer, the stiffening layer being carried by the first layer and the second layer so as to remain implanted with the first layer and the second layer in the patient.
Claim 8
Dependent Claim
123 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 to create a pouch between the first and second layers; an opening in the pouch for insertion of a finger into the pouch to position the patch across the tissue aperture; and a resilient stiffening layer within said pouch for supporting the first layer and the second layer, the stiffening layer being carried by the first layer and the second layer so as to remain implanted with the first layer and the second layer in the patient.
Claim 9
Dependent Claim
25 words
A patch according to claim 6 , wherein the opening in said pouch comprises: a slit in one of said first and said second layers.
Claim 10
Dependent Claim
54 words
The patch according to claim 6 , wherein: said first layer is secured to said second layer by a seam extending around a periphery of said pouch; and at least one of said first and said second layers has a border that extends beyond said seam to fill uneven voids in a patient's tissue.
Claim 11
Dependent Claim
29 words
The patch according to claim 6 , wherein the support member is comprised of mesh monofilament fibers and has a greater stiffness than said first and said second layers.
Claim 12
Dependent Claim
155 words
A tissue aperture repair patch, comprising: a first layer of inert synthetic mesh material sized and shaped to extend across and beyond a tissue aperture; a second layer of inert synthetic mesh material overlying the first layer to create a generally planar configuration for the patch; the first and second layers being joined together by a seam that defines a pouch between the layers; an opening in one of the layers for insertion of a finger of a surgeon into the pouch to facilitate insertion of the patch into the patient and to position the patch across the tissue aperture; and a resilient stiffening layer of inert synthetic mesh material located within the pouch and proximate the seam for urging the patch to conform to the generally planar configuration across the tissue aperture as the surgeon withdraws his or her finger, the stiffening layer having a greater stiffness than said first and said second layers.
Claim 13
Dependent Claim
155 words
A tissue aperture repair patch, comprising: a first layer of inert synthetic mesh material sized and shaped to extend across and beyond a tissue aperture; a second layer of inert synthetic mesh material overlying the first layer to create a generally planar configuration for the patch; the first and second layers being joined together by a seam that defines a pouch between the layers; an opening in one of the layers for insertion of a finger of a surgeon into the pouch to facilitate insertion of the patch into the patient and to position the patch across the tissue aperture; and a resilient stiffening layer of inert synthetic mesh material located within the pouch and proximate the seam for urging the patch to conform to the generally planar configuration across the tissue aperture as the surgeon withdraws his or her finger, the stiffening layer having a greater stiffness than said first and said second layers.
