Implant assist apparatus
First Claim
1. An implant assist apparatus for implanting material in tissue to be approximated or reinforced comprising:
- cannula means having a hollow body and an open proximal and distal end;
point means detachably fixed to said open proximal end of the cannula means for penetrating tissue;
guide wire means attached to said point means and extending into said open proximal end of the cannula means; and
implant material releasably attached to said guide wire means and extending from said open distal end of the cannula means.

Abstract
An implant assist apparatus is disclosed for implanting material such as a suture in tissue to reapproximate or reinforce the tissue. A cannula is provided having a hollow body and an open proximal and distal end. Point means is detachably fixed to the open proximal end of the cannula for penetrating tissue. A method of implanting the material in tissue for reapproximating or reinforcing the tissue with the implant assist apparatus is also disclosed whereby a length of the implant material is attached to a guide wire for partial containment within the cannula. The cannula with detachable point is passed into the tissue at an entry point remote from one side of the defect and out an exit point on the opposite side remote from the defect such that the distal end of the hollow body extends from the entry point and a proximal end extends from the exit point. The detachable point is removed from the cannula and a guide wire with implant material attached is drawn out of the proximal end of the hollow body until the implant material is exposed at both the distal and proximal ends of the hollow body. Thereafter, the cannula is withdrawn from the tissue leaving the implant material in place and the implant material is anchored to reapproximate or reinforce the defect.

13. A method of implanting material in tissue for reapproximating or reinforcing defects therein comprising the steps of:
-
providing cannula means having a hollow body open at both ends and a detachable point at a proximal end thereof, said detachable point having a guide wire attached and extending into said hollow body; attaching a length of implant material to said guide wire; passing said cannula means with detachable point and implant material into the tissue at an entry point remote from one side of the defect and out of an exit point in an opposite side remote from the defect such that a distal end of said hollow body extends from the entry point and a distal end extends from said exit point; removing said detachable point from said cannula means and drawing the guide wire with implant material attached out of the proximal end of said hollow body until the implant material is exposed at both the distal and proximal ends of the hollow body, withdrawing said cannula means from said tissue, leaving the implant material in place, and anchoring the implant material to reapproximate or reinforce the defect. - View Dependent Claims (14)
