WOUND CLOSURE DEVICE

摘要

A device is provided for closing a wound, such as a percutaneous access site. The device is inserted into the wound, and a helically shaped pusher is actuated to penetrate a wall of the wound. The pusher extends a suture through the tissue wall. After the suture is extending through the tissue wall, the pusher is retracted out of the tissue, while the suture remains extending through the tissue. The suture may then be used to close the wound.

主权项

1. A wound closure device, comprising:
a pusher comprising a distal portion with a helical shape; a housing supporting said pusher, said distal portion of said pusher being extendable along a helical path exterior from said housing; a sharp tip disposed at a distal end of said distal portion of said pusher; and a suture portion engaged with said pusher; wherein said pusher is configured to push said sharp tip along said helical path to penetrate body tissue, said suture thereby being pulled through said body tissue along said helical path, said suture thereafter being separable from said pusher, and said pusher being retractable from said body tissue along said helical path to leave said suture extending through said body tissue.
