Title: Surgical clip applier
Inventor: PETERS STEPHEN F
IPC: A61B17/128
Filed: 2001-02-02
Abstract: A surgical clip applier (10) for application of surgical clips (12) to body tissue is disclosed. The clip applier includes an elongated housing (18) having proximate (20) and distal (22) ends. This housing also defines a feed surface for the surgical clips.  The clip applier also includes first and second jaws (30) extending from the distal end of the housing. The jaws open and close to apply the surgical clips to the body tissue of the patient.
