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 body of a living being formed during a minimally invasive surgical procedure to prevent the egress of tissue into the puncture, the puncture comprising an opening in internal tissue in the body of the being and a tract extending from the skin of the being to the opening in the tissue, said device comprising anchoring means, filament means, and suturing means, said anchoring means being an elongated substantially rigid member arranged to be extended through the tract and the opening and being orientable for engaging the interior of the tissue adjacent the opening to render said anchoring means resistant to passage back through the opening, said filament means including a first portion and a second portion, said first portion extending between said anchoring means and said second portion and being coupled to said anchoring means for location within the tract, said second portion of said filament means extending out of the tract, said suturing means being coupled to said second portion of said filament means and being operative to cause said second portion of said filament means to penetrate tissue contiguous with the tract for holding said anchoring means permanently in place with respect to the puncture, with said anchoring means blocking at least a portion of the opening to prevent tissue from gaining egress into the 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 sealing device and a deployment instrument. In one embodiment the sealing 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. 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 is operated to place the anchor in the interior of the peritoneum and the plug and the holding member in the puncture tract, with both ends of the filament extending out of the puncture. 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. In an alternative embodiment the sealing device comprises only the anchoring member and the filament.

41. A method of preventing the egress of tissue into a percutaneous puncture formed during a minimally invasive surgical procedure on the body of a living being, said puncture having an opening in internal tissue in the body of the being and a tract extending from the skin of the being to the opening, said method comprising:
-
(a) providing a sealing device comprising anchoring means and filament means, said filament means being coupled to said anchoring means and including at least a first portion, (b) introducing said device through the puncture from the outside of the being'"'"'s body and orienting said anchoring means so that said anchoring means engages the interior of the tissue adjacent the opening to render said anchoring means resistant to passage back through the opening, and (c) causing said first portion of said filament means to extend through the tract and securing said first portion of said filament means in place with respect to the tract for holding said anchoring means in place within the puncture, whereupon said anchoring means serves to block at least a portion of the opening to prevent the egress of tissue into the puncture. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54)
