Abstract
A wound closure assembly includes an insertion tool having a proximal end and a distal section, such as a curved distal section, having a penetrating tip and first and second notches that are formed on opposite sides of the distal section. The assembly includes a tissue anchor having a hollow body and an insertion tool channel extending through the hollow body. First and second spaced tips project distally from the distal end of the hollow body and oppose one another on opposite sides of the insertion tool channel. The distal section of the insertion tool is inserted into the insertion tool channel of the tissue anchor so that the penetrating tip is distal to the first and second spaced tips, with the first and second spaced tips nested within the first and second notches for generating a releasable interference fit between the tissue anchor and the insertion tool.
