1. An anastomotic device for temporarily rejoining and reforming a damaged blood vessel, comprising:
- a first, flexible tubular casing, made of expansible material, having inner and outer faces and two ends, one end of which terminates in a female connector;
a first cylinder, having inner and outer faces, not subject to collapse or kinking, concentrically positioned within said first casing, extending to and open at both ends of the casing, and so joined to said first casing as to form an enclosed first chamber around and between the outer face of said first cylinder and the inner face of said first casing;
a means for inflating said first chamber;
a second, flexible tubular casing, made of expansible material, having inner and outer faces and two ends, one end of which terminates in a male connector which interconnects to the first casing'"'"'s female connector;
a second cylinder, having inner and outer faces, not subject to collapse or kinking, concentrically positioned within said second casing, extending to and open at both ends of the casing, and so joined to said second casing as to form an enclosed second chamber around and between the outer face of said second cylinder and the inner face of said second casing; and

Abstract
An anastomotic device for temporary installation in a damaged blood vessel, having a generally tube-like shape, and whose purpose is to maintain blood flow within the blood vessel while substantially halting bleeding. The device is so inserted into the damaged blood vessel that it reconnects and reforms the blood vessel through the damaged area. The device contains an enclosed chamber, inflatable from an external source, concentric about an inner cylinder with open ends. The inner cylinder maintains blood flow while the inflated air chamber causes the device to fit snugly enough within the blood vessel to halt external bleeding.
