Abstract

An improved surgical fastener having at least one head portion and a filament portion arranged in a T configuration, wherein at least one end of the said at least one head portion is sharply pointed, so that when that head portion is implanted in body tissue, the head portion will attach itself securely to the tissue and will remain there despite the application of a substantial pulling force on the filament portion.
