ABSTRACT:
A self anchoring catheter and delivery system therefor for performing cholecystectomies through a laparoscope so that the catheter can be properly delivered to the cystic duct and so that the catheter will not undesirably fall out of the cystic duct during the cholangiogram. The anchoring portion can be an inflatable balloon which is inflated only when a material is injected through the catheter into the cystic duct. In the alternative, the anchoring portion can be a hub formed from a foam rubber or cellular plastic material which is compressible and has a non-smooth exterior surface whereby the anchoring portion will snugly engage and frictionally retain the catheter within the cystic duct until a positive force is applied to withdraw the same from the duct. The self anchoring catheter is delivered to the cystic duct through a delivery sleeve which is sized so as to be insertable through a standard laparoscope introducer sheath. The distal end of the sleeve can be straight or can be jointed to allow the distal end to be bent to allow directional control of the catheter into the cystic duct. The bendable delivery sleeve or sheath has other applications in the field of intra-abdominal surgery. Indeed, the delivery sleeve, alone, can be used as a disposable laparoscopic directional tip suction device, to house a laser fiber delivery system, or to house a cautery device.
