ENDOSCOPIC FIXATION OF A MEDICAL DEVICE USING MUCOSAL CAPTURE

摘要

An endoscopic method of fixing an intraluminal device in a lumen or hollow organ lined with mucosa includes positioning the intraluminal device in the lumen or hollow organ lined with mucosa and having a fixation device at a distal end portion of the endoscope. A fixation device at a distal end of an endoscope includes a body having a distal sealing portion. The sealing portion is positioned against the wall of the intraluminal device over a mucosal capture opening. Suction is applied through the endoscope and body to at least partially draw mucosa into the mucosal capture opening. The mucosa is retained in the mucosal capture opening.

主权项

1. An endoscopic intraluminal device fixation device that is adapted to fix an intraluminal device in a lumen or hollow organ lined with mucosa, said intraluminal device having a device wall and at least one mucosal capture opening in said wall, said endoscopic intraluminal device fixation device comprising:
a body having a proximal support portion and a distal sealing portion defining a distal surface; said support portion has sufficient strength to support said body from a distal end of an endoscope and said sealing portion configured to form a fluid seal with the wall of the intraluminal device; and said body defining a suction passage, said suction passage adapted to communicate suction from the endoscope to said distal surface to at least partially draw mucosa into the mucosal capture opening.
