ABSTRACT:
A combination catheter and duct clamp apparatus and method. The apparatus includes a hollow member with a substantially planar clamping surface at one end and a sliding member with a substantially planar clamping surface at one end which is telescopically slidable within the hollow member. A spring maintains an essentially constant clamping pressure between the clamping surfaces.
The clamp is ideally suited for use during cholangiography where it may be used for inserting a catheter within the cystic duct and for thereafter clamping the cystic duct around the catheter. The clamping pressure provides an adequate seal of the cystic duct and does not occlude the inserted catheter. Multiple clamping angles give the clamp unique versatility during the surgical procedure. Being constructed out of a radiolucent material, the clamp may be left in place while a cholangiogram is taken without interfering with the completed cholangiogram.
