Multiple hemoclip system for an endoscope

A method, comprising:

• inserting a distal portion of a tissue clipping device into a living body such that distal ends of an inner and outer sleeve are positioned adjacent to a target tissue, the outer sleeve extending longitudinally from a proximal end to a distal end and including a first lumen extending therethrough, the inner sleeve within the outer sleeve and movable relative thereto, the inner sleeve extending longitudinally from a proximal end to a distal end and including a second lumen extending therethrough;
• pushing a plurality of clips distally through the second lumen until a distal-most one of the clips contacts ramped surfaces of a clip opening element fixedly attached to the distal end of the inner sleeve such that contact between the ramped surfaces and the distal ends of the jaws spread opposing jaws of the distal-most clip apart into a tissue receiving configuration, the jaws being biased toward a closed configuration, the pushing element being within the second lumen and positioned proximally of a proximal-most one of the clips;
• and
• receiving the target tissue between the opposing jaws of the distal-most clip in the tissue receiving configuration.

A tissue clipping system, comprising:

• an outer sleeve extending longitudinally from a proximal end to a distal end and including a first lumen extending therethrough;
• an inner sleeve within the outer sleeve and movable relative thereto, the inner sleeve extending longitudinally from a proximal end to a distal end and including a second lumen extending therethrough;
• a plurality of clips slidably received within the second lumen, each of the clips including a pair of opposing jaws coupled to one another at a proximal end, the jaws being biased toward a closed configuration in which distal ends of the jaws are adjacent one another;
• a pushing element within the second lumen proximal of a proximal-most one of the clips and longitudinally movable relative to the inner sleeve to push the clips distally through the second lumen;
• a clip opening element fixedly attached to the distal end of the inner sleeve including ramped surfaces positioned so that, when the pushing element pushes a distal-most one of the clips out of the distal end of the inner sleeve, contact between the ramped surfaces and distal ends of the jaws of the distal-most one of the clips spread the jaws apart from one another away from the closed configuration to a tissue receiving configuration;
• and
• an actuator coupled to the pushing element via a control wire such that, in an operative position, the actuator remains outside of a living body accessible to a user to move the pushing element proximally and distally relative to the inner sleeve.
