Abstract:
An apparatus for closing a septal defect, comprising:a clip formed from an elastic material having at least two penetrating tines and an opposing retaining end, the clip having a relaxed configuration in which the tines are inflected back on themselves, the clip being biased so as to project the at least two penetrating tines distal to the opposing retaining end, wherein when the bias is removed, the at least two penetrating tines move laterally apart from one another, a tubular member comprising proximal and distal ends and a lumen therebetween, the distal end having a size for insertion into a blood vessel, the clip being carried within the lumen such that the penetrating tines are disposed distally to the retaining end; a pusher member slidably disposed within the lumen, the pusher member comprising a distal end disposed proximate to the retaining end of the clip, the pusher member being movable axially relative to the tubular member for ejecting the clip distally from the lumen; and at least one axially disposed clip-retaining groove located in an inner surface of the tubular member.
