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. One or both of the layers has a border that extends beyond the seam. A plurality of border slits extend from an outer edge of the border through the border substantially to the seam. An access slit is formed between the layers for insertion of a finger of a surgeon into the pouch to allow the surgeon to deform the planar configuration of the patch to facilitate insertion of the patch into the patient and to position the patch across the hernia. A resilient monofilament spring is located within the pouch at the seam for urging the patch to conform to the generally planar configuration across the hernia as the surgeon withdraws his or her finger.

Claims

1. A tissue aperture repair patch for implanting within a patient, comprising:

at least one layer of inert synthetic mesh material sized and shaped to extend across and beyond a tissue aperture in a patient;

a resilient support member adjacent a periphery of the layer and configured in an open loop to urge the layer into a planar configuration, said support member carried by the layer so as to remain implanted with the layer in the patient; and

the layer of inert synthetic mesh material having a periphery extending beyond the support member that defines a border having a free outer edge to fill uneven voids in a patient'"'"'s tissue.

2. The patch according to claim 1 wherein the support member is comprised of monofilament fiber.

3. The patch according to claim 1, further comprising a seam between said layers that restrains said resilient support member in said configuration.

4. The patch according to claim 1 wherein said resilient support member has two ends that are spaced apart from each other by a gap.

5. The patch according to claim 1 wherein:

said line has two ends that are spaced apart from each other by a gap; and

wherein said line has a length greater than a length of said gap.

6. 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 providing access to an interior of the pouch to position the patch across the tissue aperture; and

a resilient support member adjacent a periphery of the pouch and configured in an open loop to cause the layers to assume a flat shape, the support member being carried by the layers so as to remain implanted with the layers in the patient.

7. The patch according to claim 6, wherein:

the support member is a monofilament fiber located within the pouch.

8. The patch according to claim 6, further comprising a seam between said layers that restrains said resilient support member in said configuration.

9. The patch according to claim 6 wherein said resilient support member has two ends that are spaced apart from each other by a gap.

10. The patch according to claim 6 wherein:

said support member has two ends that are spaced apart from each other by a gap; and

wherein said support member has a length greater than a length of said gap.

11. The patch according to claim 6, wherein:

the opening in the pouch comprises a slit in one of the first layer and the second layer.

12. 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 which defines a pouch between the layers;

an opening in one of the layers that enables 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 support member located within the pouch and adjacent to 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, said resilient support member being a monofilament fiber loop having a curved portion, said resilient support member restrained in a configuration of an open loop by said seam.
