First Claim
Patent Images
1. A polymeric non-snag 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;
(b) a hinge section integrally disposed between and joining 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; and
(d) at least one first recess substantially submerged within one of the pair of opposing side surfaces of said first leg, and at least one second recess substantially submerged within one of the pair of opposing side surfaces of said second leg, said at least one first and second 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. 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.

14. 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; (b) a hinge section integrally disposed between and joining 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; and (d) protuberance means for engaging and applying the surgical clip by a clip applier apparatus, wherein the protuberance means deflects engagement with a suture during a surgical procedure.
