Surgical marker clip and method for cholangiography
First Claim
1. A duct marker clip for releasably securing to a duct during surgical laparoscopic procedures for visual identification of a work area, comprising a first arm and a second arm, each arm having a first end and second end and wherein the arms are pivotally connected intermediate the first end and second end, and wherein the first and second arm at the first end each are curved generally inward, with each arm having inner surfaces for frictionally engaging the duct.

Abstract
A surgical marker clip and method for enhancing the safe performance of a cholangiography and cholecystectomy is disclosed. The clips are configured to frictionally engage the outer surface of the duct and are retained in place by light clamping force without damaging the duct. Placement of the clips allows a physician to visually isolate the common bile duct from the cystic duct during laparoscopic procedures which reduces bile duct injury typically caused by misidentification or visual misperception of the anatomy during the procedure.

- 6. A duct marking clip comprising a first leg connected at an apex to a second leg, each leg having a jaw end and a bend intermediate the apex and the jaw end, such that the bends are oriented generally outward from the apex and the jaw ends and accordingly the clip has a substantially diamond shaped cross section.

10. A method for visually identifying a duct during a laparoscopic cholecystectomy, comprising the steps of:
- identifying and dissecting the cystic duct;
marking the cystic duct by placing at least two marking clip around the outer wall of the cystic duct to define a work area;
attenuating the gallbladder percutaneously with a needle, placing a catheter through the gallbladder into the cystic duct;
injecting a contrast into the gallbladder and cystic duct;
visually identifying the defined work area on the cystic duct; and
visually discerning the cystic duct from the common bile duct or hepatic duct. - View Dependent Claims (11)
