Abstract
An intratubular anastomosis apparatus for joining organ portions of a hollow organ after intussusception which includes an anastomosis ring, and a crimping support element. The anastomosis ring includes a length of a wire formed of a shape memory alloy for crimping adjacent organ portions against the crimping support element so as to cause anastomosis. The anastomosis ring and the shape memory alloy assumes a plastic state, when at a first, lower temperature and an elastic state, when reaching at least a second, higher temperature. The crimping support element provides a support for crimping the organ portions against the support element. Using the anastomosis ring and crimping support element of the present invention reduces the risk of leakage and no staples or sutures remain within the anastomosed organ portion.
