Abstract

The invention is directed to a medical device for endoscopically ligating and cutting a body vessel. The device may be percutaneously inserted into a patient to perform several possible procedures. The improvements to the device include a hinged jaw capable of grasping and crimping body vessels. An improved clip delivery system and an improved clip which ligate body vessels are also described. The instrument includes a rotating cutting member which provides more efficient body vessel cutting means. Furthermore, the entire system allows a simplified and more efficient method of operation.
