DIVERTICULUM INVERSION USING A CLIP PLACEMENT DEVICE

摘要

Several embodiments disclosed herein relate to apparatus and methods for treating a diverticulum. In some examples, disclosed is a clip placement device for diverticulum inversion. The clip placement device can include a clip tube, a clip, a clip attachment structure, and an expansion apparatus. A method for clip placement for diverticulum inversion can also be included. The method can include positioning the distal end of a clip placement device along an outer wall of a colon at a diverticulum, inverting the diverticulum, and advancing a portion of the clip placement device into the inverted diverticulum. The diverticulum can then be expanded with the expansion apparatus. The method can then include engaging the clip with the diverticulum, and withdrawing the clip placement device in a proximal direction such that that clip attachment structure disengages from the clip from the clip placement device.

1. A method of clip placement for diverticulum inversion, the method comprising:
positioning the distal end of a clip placement device along an outer wall of a colon at a diverticulum; inverting the diverticulum into the lumen of the colon with a distal end of a pusher structure within the clip placement device; advancing a portion of the clip placement device into the inverted diverticulum, wherein the clip placement device comprises the pusher structure, a clip tube, a clip, a clip attachment structure configured to reversibly engage the clip at the distal end of the clip tube, and an expansion apparatus; expanding the diverticulum with the expansion apparatus such that the volume of the diverticulum increases; engaging the clip with the diverticulum; and withdrawing the clip placement device in a proximal direction such that the clip attachment structure disengages the clip from the clip placement device.
