Abstract
Implantable medical devices for connecting tissue layers, such as for connecting a gallbladder and a portion of a gastrointestinal tract to create an anastomosis, include a tubular structure having a plurality of apposition portions, a central region, and a covering material. The methods of using the devices include endoscopic deployment, and the devices may include self-expanding frameworks that facilitate a secure connection between the tissue structures.
Claims22
A medical device comprising:
- a frame comprising an elongate member defining:
- a first apposition portion comprising one or more first flange members configured to contact a first tissue surface and to provide an apposition force against said first tissue surface;
- a second apposition portion comprising one or more second flange members configured to contact a second tissue surface and to provide an apposition force against said second tissue surface;
- and
- a central portion having a first end and a second end, said central portion defining a longitudinal axis, said central portion being disposed between and interconnecting said first apposition portion and said second apposition portion,
- wherein at least one of said one or more first flange members and at least one of said second flange members comprises a radius portion and a descending portion that extends longitudinally toward said central portion,
- wherein at least one of said radius portions of said one or more first flange members extends longitudinally beyond said first end, and
- wherein at least one of said radius portions of said one or more second flange members extends longitudinally beyond said second end.

An anastomosis device comprising:
- a frame comprising an elongate member defining:
- a first apposition portion comprising one or more first flange members configured to contact a first tissue surface and to provide an apposition force against said first tissue surface;
- a second apposition portion comprising one or more second flange members configured to contact a second tissue surface and to provide an apposition force against said second tissue surface;
- and
- a central portion having a first end and a second end, said central portion comprised of a framework of one or more elongate elements and defining a longitudinal axis, said central portion being disposed between and interconnecting said first apposition portion and said second apposition portion,
- wherein the central portion includes one or more axial adjustment members extending along the longitudinal axis of the central portion configured to allow the central portion to elastically extend or contract the central portion along the longitudinal axis.
