• g) a clip chamber adapted to store at least one surgical clip, said clip pusher extending into said clip chamber and adapted to advance a clip from said clip chamber between said jaws;
• and
• i) at least one clip in said clip chamber having first and second arms and a bridge portion therebetween to together define a generally U-shaped construct, the first arm extending into a deformable retainer,
• wherein when said clip pusher is advanced, said first and second arms of one of said at least one clip are moved through said first and second clip guides, and said deformable retainer of said one of said clips is bent by the anvil toward said second arm to extend into said well and around an end of said second arm of said one of said clips.
