MUCOSAL CAPTURE FIXATION OF MEDICAL DEVICE

摘要

A medical device adapted to be fixed in a hollow organ or cavity lined with mucosa includes a wall having an outer surface with a size and shape that is configured to a portion of a cavity or hollow organ lined with mucosa and a fixation mechanism. The fixation mechanism is adapted to fix the wall with the portion of the cavity or hollow organ. The fixation mechanism has at least two adjacent openings in the wall between proximal and distal ends of the wall. The openings being large enough to receive a section of the mucosa extending in the openings when said wall is positioned in the hollow organ or cavity. The openings are separated by a bridge and are close enough together that the mucosa that extends into the openings comes together over the bridge to fix the medical device in the hollow organ or cavity.
