Abstract
The present invention describes apparatus and methods for tying a filament across subcutaneous punctures. According to some embodiments, the apparatus and methods provide pre-tied knots that are inserted into a bodily lumen. Needles flanking the subcutaneous puncture are inserted into the lumen and grab the pre-tied knots. The pre-tied knots are pulled through tiny holes flanking the subcutaneous puncture by the needles, leaving an internal length of the filament across the subcutaneous puncture. The filament is then externally tied, closing the subcutaneous puncture.
