摘要：
An implantable medical device for sealing and repairing defects in a body tissue or for creating an anastomosis includes a frame (1000, 100, 1410, 1610, 1810, 1910, 191, 1, 2210, 2310, 400, 700) and a covering material (1110, 1412, 1612, 1812, 1912, 210, 2214, 2314, 510, 810). In some embodiments, the frame (1000, 100, 1410, 1610, 1810, 1910, 191, 1, 2210, 2310, 400, 700) includes a single continuously wound wire that defines an apposition portion (1020, 120, 130, 1420, 1820, 1920, 1, 420, 720), a defect-occupying portion, and a sealing portion (1030, 130, 1430, 1830, 1930, 430, 730). In some embodiments, the tissue-sealing and anastomosis devices provided herein are well-suited for use in the Gl tract including the small bowel and colon. In some embodiments, a two-part frame (1000, 100, 1410, 1610, 1810, 1910, 191, 1, 2210, 2310, 400, 700) construct facilitates independent tailoring of apposition forces and radial forces exerted on tissues by the two-part frame (1000, 100, 1410, 1610, 1810, 1910, 191, 1, 2210, 2310, 400, 700)
