Non-snag polymer ligating clip
First Claim
1. A polymeric non-snag, low profile surgical clip comprising:
- (a) a first leg and a second leg, each of said legs having an inner vessel-clamping surface, an outer surface and a pair of opposing side surfaces flanking said inner and outer surfaces, said inner surfaces being positioned in opposition to each other;
(b) a flexible hinge section integrally disposed between and joining the proximal ends of said first and second legs;
(c) a female locking member positioned on the distal end of said first leg and a male locking member positioned on the distal end of said second leg, said female and male locking members being formed whereby when said first and second leg members are moved from an open position to a closed position about said hinge section, said male locking member is lockingly engaged in said female locking member so as to removably lock said first and second leg members of said surgical clip in said closed position; and
(d) a first pair of recesses formed in opposite sides of said first leg between said hinge section and the distal end of said first leg, and a second pair of recesses formed in opposite sides of said second leg adjacent the distal end of said second leg, said first and second pair of recesses serving to allow for engagement and application of the surgical clip by a clip applier apparatus.

Abstract
A polymeric, surgical clip having first and second curved legs with each having a pair of opposing side surfaces joined at their proximal ends by a flexible hinge section and movable from an open position to a closed position for clamping a vessel between curved opposing inner surfaces. The first leg terminates at its distal end in a female locking member, and the second leg member terminates in a male locking member complimentary to the female locking member such that when the first and second leg members are moved from an open position to a closed position about the hinge section the male member is lockingly engaged in the female locking member. The clip is provided with low profile boss-like elements on the legs thereof to reduce the risk of snagging a suture during coronary artery bypass graft surgery.
