Abstract

A support device for endoscopic suturless anastomosis between tubular organs include at least a first tubular member provided with a longitudinal slit which permits introduction of the organs to be anastomosed in the device and additional second tubular members in physical continuity with the first tubular member through an opening on the first tubular member. The size of the opening is substantially equal to the luminal area of the second member. The inner and outer diameters of any radial cross section of the second members are constant along its length. The device allows apposition of the two tubular organs to be anastomosed in a variety of spatial patterns and their fixation to each other without sutures or clips, either manually or via remote control, and the creation of luminal continuity between them.

Dependent claims

A device for endoscopic suturless anastomosis of tubular organs selected from the group comprising blood vessels and extravascular tubular structures such as the esophagus, intestines, ureter, biliary ducts, fallopian tubes, etc., said device comprising a first curved member and one or several second tubular members, wherein

the first curved member is a first tubular member provided with an opening for communication with the second tubular member, and a slit which extends longitudinally throughout the whole length of the first curved member, for placement of the device externally to said organs, such that the anastomosis is externally supported by the device;
inner surfaces of the first and the second members are in continuity, such that the size of the opening on the side of the first member is substantially equal to a luminal area of the second members;
and
inner and outer diameters of any radial cross section of the second member are constant along the length of the second member.
