1. A surgical instrument for fixation of tissues, comprising:
- a main body portion having a sharpened distal end and a proximal end;
a shaft portion, having distal and proximal ends, slidingly disposed within said main body portion such that the distal end of said shaft portion may extend beyond the distal end of said main body portion; and
a repair member configured and dimensioned to be received within said main body portion and cooperate with the distal end of said shaft portion for ejection from said main body portion, said repair member having at least one end adapted for placement within biological tissue and including tissue securing means adapted to hold at least two sections of said tissue in close proximity to one another;
wherein said shaft portion and said main body portion cooperate together to position said repair member within said tissue and activate said tissue securing means to hold together separated tissue layers.
