1. A hemostatic clip application system for dispensing and applying preformed, generally V-shaped hemostatic clips to a blood vessel, said system comprising:

  • at least one clip comprising a pair of legs having first and second regions and a connecting portion extending therebetween and connecting said first regions of said legs;

    a cartridge body base having a longitudinal axis;

    a cartridge body comprising a plurality of substantially parallel walls extending upwardly from said base and substantially transverse to said longitudinal axis, said walls being spaced apart and having first and second substantially parallel, opposed wall faces defining slots to retain said clip, said slots including a saddle extending between said faces for mounting said clip within said slot and being adapted to permit relative movement of said clip with respect to said saddle, said saddle being configured and dimensioned to closely conform to an inner peripheral edge of said clip adjacent said first regions and said connecting portion thereof;

    at least one retaining member protruding from said faces defining said slot, said retaining member interfering with said clip at a pinch point located on an apex thereof to an extent sufficient to hold said clip in said slot while permitting relative movement between said clip and said saddle, said clip being disposed on said saddle such that the clearance between said lower regions of said clip legs and said walls of said slots is of a predetermined dimension; and

    a clip applier for application of said clip about said blood vessel, said clip applier including a pair of opposed, articulating jaws formed thereon, said jaws having a pair of opposed grooves formed therein to grasp and withdraw said clip from said slots within said cartridge body, said jaws being configured to be insertable between said wall faces defining said slots to withdraw said clip without contacting said wall faces thereby eliminating any interference between said jaws and said wall faces to facilitate removal of said clip.
