Abstract
The present embodiments provide medical apparatuses and methods for rapidly forming an anastomosis between two viscera. The medical apparatus generally comprises affixing a clamp to an elongate member. The method generally comprises positioning and then deploying the medical apparatus between and within two stomas via an elongate member.
Claims20
An apparatus for facilitating the creation of an anastomosis in bodily tissue, the apparatus comprising:
- a first clamp comprising a first exterior clamp member and a first interior clamp member, the first clamp operable between a deployed configuration and a delivery configuration, the first clamp being biased towards the deployed configuration;
- a second clamp comprising a second exterior clamp member and a second interior clamp member, the second clamp operable between a deployed configuration and a delivery configuration, the second clamp being biased towards the deployed configuration;
- the interior and exterior clamp members of the first clamp connected together at their ends by hinged regions, and the interior and exterior clamp members of the second clamp connected together at their ends by the hinged regions;
- the exterior and interior clamp members of the first clamp being coplanar in the deployed configuration, and the exterior and interior clamp members of the second clamp being coplanar in the deployed configuration;
- and
- the exterior and interior clamp members of the first clamp being moved away from each other, out of plane, in the delivery configuration, and the exterior and interior clamp members of the second clamp being moved away from each other, out of plane, in the delivery configuration.

- and
- an elongate tubular member defining a longitudinal axis, wherein the first and second clamps are sized to fit within the elongate tubular member in their delivery configuration and maintain their bias towards the deployed configuration, and upon release from the tubular member automatically move towards the deployed configuration.

An apparatus for facilitating the creation of an anastomosis in bodily tissue, the apparatus comprising:
- an exterior annular member being elongated in a lateral direction, the exterior annular member forming an enclosed elongated ring and defining a first interior space;
- an interior annular member being elongated in the lateral direction, the interior annular member being received within the first interior space, the interior annular member forming an enclosed elongated ring and defining a second interior space;
- and
- hinged regions connecting the exterior and interior annular members, the hinged regions structured to permit the exterior and interior annular members to move relative to each other.
