System for closing a percutaneous puncture formed by a trocar to prevent tissue at the puncture from herniating
First Claim
1. A device arranged for introduction through a percutaneous puncture into the abdomen of a living being formed during a minimally invasive surgical procedure to prevent the formation of a hernia thereat, the puncture comprising an opening in the peritoneum and a tract extending from the skin of the being to the opening, said device including a portion arranged for disposition within the puncture and constructed of a material which serves to improve the long-term strength of tissue forming at the opening when said device is in place within the puncture, said device comprising a first member, a second member, and suturing means, said first member being arranged to be extended through the tract and the opening and into engagement with the interior of the peritoneum adjacent the opening to render said first member resistant to passage back through the opening, said second member being arranged for extension through the tract outside the peritoneum and coupled to said first member and cooperating with said first member for holding said first member in engagement with the interior of the peritoneum adjacent the opening, said suturing means being coupled to said second member and operative to cause a part of said second member to penetrate tissue of the being contiguous with the tract to permanently hold said device in place within said puncture.

Abstract
A system and method for sealing a percutaneous puncture extending into internally located tissue, e.g., the peritoneum, of a living being. The system includes a reinforcing device and a deployment instrument. The device comprises a substantially rigid anchor, a resorbable holding member, a collagen plug, and a resorbable thin filament connecting the anchor, holding member, and plug in a pulley-like arrangement. The anchor or the plug or both may be formed of a resorbable material having a non-resorbable mesh reinforcement embedded therein. The deployment instrument includes a tubular carrier in which the closure and a tamping member are located. The tamping member is operated to expel the closure so that the anchor is in the interior of the peritoneum and the plug and the holding member are in the puncture tract, with both ends of the filament extending out of the puncture and with the holding member fixedly secured to a portion of the filament adjacent one end. The other end of the filament is then drawn proximally while the tamping is pushed distally to draw the anchor member against the tissue contiguous with the opening. The tamper mechanically deforms the plug within the tract. The extending ends of the filament are formed into a knot, a portion of which extends through the skin contiguous with the puncture, to lock the closure in place. The reinforced mesh of the closure reinforces any scar tissue which forms at the opening.

30. A method of strengthening tissue which forms at an opening in internal tissue within the body of a living being, the opening comprising a portion of a percutaneous puncture having a tract extending from the skin of the being to the opening and being formed during a minimally invasive surgical procedure on the being, said method comprising:
-
(a) providing a device arranged for disposition within the puncture to improve the long-term strength of tissue forming at the opening, said device comprising securement means for holding said device in place within said puncture, said securement means comprising a first portion and a second portion; (b) providing an instrument for placing said device within the puncture; (c) using said instrument to insert said device into the puncture from the outside of the being'"'"'s body so that said first portion of said securement means is extended through the tract and the opening and into engagement with the interior of the internal tissue adjacent the opening to render said first portion of said securement means resistant to passage back through the opening; and (d) causing said second portion of said securement means to be located outside the internal tissue but coupled to said first portion of said securement means and cooperating therewith for holding said device in place within the puncture, whereupon the placement of said device within the puncture improves the long-term strength of tissue forming at the opening. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
