Patent ID: 7169167

Claim:
An endoscopic device configured to be loaded into a channel of an endoscope prior to insertion of the endoscope into a body, comprising: an elongate member for insertion into the channel of the endoscope, wherein a length of the elongate member is greater than a length of the channel of the endoscope; and a distal assembly connected to a distal portion of the elongate member and operable to perform an endoscopic operation, wherein the distal assembly has an open configuration and a closed configuration, wherein a proximalmost end surface of the distal assembly substantially transverse to the elongate member has a diameter larger than a diameter of a distalmost end of the channel of the endoscope, and wherein the distal assembly is adapted to be exterior to the channel when the endoscope is inserted into the body, wherein the distal assembly includes a tube and an end effector having a profile in the closed configuration that is smaller than a profile of a lumen of the tube so that at least a portion of the end effector fits within the lumen of the tube when in the closed configuration, wherein the end effector includes only two jaw members operable to open and close.
