Abstract
An implantable medical device and method of implanting a medical device in a hollow organ or cavity lined with the mucosa includes providing a medical device having a wall configured to the size and shape of a portion of a cavity or hollow organ lined with the mucosa. At least one opening is provided in the wall that is large enough to receive a section of the mucosa extending in the opening. The wall is positioned against the portion of the cavity or hollow organ thereby receiving the section of the mucosa within the opening. A retainer may be provided to retain the section of the mucosa within the opening while maintaining perfusion of the section of the mucosa.
Claims19
A method of implanting a medical device in a hollow organ or cavity lined with mucosa, said method comprising:
- positioning a medical device having an expandable wall in the hollow organ or cavity lined with mucosa, said wall defining a lumen with proximal and distal ends thereof and configured to the size and shape of a portion of the organ or cavity;
- causing said wall to expand when positioned in the portion of the hollow organ or cavity in order to press said wall against the mucosa of the hollow organ or cavity;
- said wall having at least two adjacent openings separated by a bridge, said at least two adjacent openings being between said proximal and distal ends, each of said openings having a size that is large enough to cause the mucosa to bulge into that opening in a manner that maintains perfusion of the mucosa when said wall is expanded in the portion of the hollow organ or cavity;
- and
- said adjacent openings being close enough together that the mucosa that bulges into said openings comes together over said bridge to fix said medical device in said hollow organ or cavity.

- and
- promoting fusion of the mucosa that bulges into said openings.
