Abstract

A patch is made from a rolled up first flat sheet of polypropylene or polytetrafluroethylene surgical mesh. One end of the rolled up mesh has multiple slits to provide multiple flared out flaps stitched to a second flat sheet of surgical mesh. The patch is compressed into a longitudinal cylindrical structure and is inserted through a trocar into an opening of a hernia. The rolled up first flat sheet is inserted through the opening and the flaps and second flat sheet are stapled to the patient'"'"'s tissue adjacent the opening.

Claims

1. A surgical flared patch for use in laparoscopic hernia repair comprising

a rolled up sheet of a surgical plastic mesh maintained in a rolled up form by at least two bands and multiple longitudinal cuts in a first end of the rolled up mesh to form multiple flared out flaps,

a planer sheet of a surgical plastic mesh permanently attached to the flaps in a flared out position, the flaps and planer sheet being capable of compressing together as a longitudinal extension of the rolled up sheet of surgical plastic mesh and inserted into a cylindrical plastic delivery tube.

2. The surgical flared patch according to claim 1 wherein the rolled up sheet and planar sheet of surgical plastic mesh is polytetrafluoroethylene.

3. The surgical flared patch according to claim 1 wherein the rolled up sheet and planar sheet of surgical plastic mesh is polypropylene.

4. The surgical flared patch according to claim 1 wherein the planar sheet of surgical plastic mesh is stitched to the flaps by a plastic suture thread.

5. The surgical flared patch according to claim 4 wherein the plastic suture thread is polytetrafluoroethylene.

6. The surgical flared patch according to claim 4 wherein the plastic suture thread is polypropylene.

7. The surgical flared patch according to claim 1 wherein the bands maintaining the rolled up surgical plastic mesh are cat gut.

8. The surgical flared patch according to claim 1 wherein five longitudinal slits are made in a first end of the rolled up mesh to form five flared out flaps.

12. The method according to claim 7 wherein the patch is compressed into a cylindrical tube for delivery to the hernia site.

9. In a method of repairing an inguinal hernia using laparoscopic surgical procedures wherein an incision is made in a patient'"'"'s umbilicus and in the right lower abdomen and in the left lower abdomen and a patch is delivered via a trocar to an opening to be repaired, the improvement wherein,

the patch inserted into the opening is a rolled up sheet of a surgical plastic mesh maintained in a rolled up form by attaching at least two bands around the rolled up mesh and then making multiple longitudinal cuts in a first end of the rolled up mesh to form multiple flared out flaps, the flaps then being stitched to a planar sheet of plastic surgical mesh, the patch then inserted into the opening by a second end of the rolled up sheet of surgical plastic so that the rolled up portion of the patch enters the opening and the flaps and planar sheet of plastic surgical mesh are displayed out over an entrance to the opening, and then the planar sheet of plastic surgical mesh is stapled to adjacent tissue to retain the patch in position.

10. The method according to claim 9 wherein the surgical mesh employed is polypropylene.

11. The method according to claim 9 wherein the surgical mesh employed is polytetrafluoroethylene.
