Abstract
An implantable medical device for sealing and repairing defects in a body tissue or for creating an anastomosis includes a frame and a covering material. In some embodiments, the frame includes a single continuously wound wire that defines an apposition portion, a defect-occupying portion, and a sealing portion. In some embodiments, the tissue-sealing and anastomosis devices provided herein are well-suited for use in the GI tract including the small bowel and colon. In some embodiments, a two-part frame construct facilitates independent tailoring of apposition forces and radial forces exerted on tissues by the two-part frame.
Claims5
An implantable medical device, said implantable medical device comprising:
- a single elongate member forming:
- a first flange having a plurality of first arms configured about a central axis and forming a circumferential sealing portion at the outer edges of said first flange;
- a second flange having a plurality of second arms configured about said central axis, wherein said plurality of first arms has a geometry different from said plurality of second arms;
- and
- a connecting region interconnecting said first and second flanges and adapted to bridge a defect in a lumen wall,
- wherein said first arms and said second arms have a pre-strained geometry such that an apposition force exists in the absence of a lumen wall.
