Patent ID: 7094247

Claim:
An intratubular anastomosis apparatus for joining organ wall portions of a hollow organ after intussusception, said apparatus including: a) an anastomosis ring, including a length of a wire formed of a shape memory alloy defining a closed generally circular shape, having a central opening, and having overlapping end portions, said anastomosis ring for crimping adjacent intussuscepted organ wall portions against a crimping support element so as to cause anastomosis therebetween, wherein, said anastomosis ring and said shape memory alloy assumes i) a plastic or malleable state, when at a first, lower temperature; and ii) an elastic state, when reaching at least a second, higher temperature, thereby enabling said anastomosis ring to retain a preselected configuration at the first, lower temperature, and an elastic crimping configuration upon reverting to the second, higher temperature; and b) said crimping support element for intratubular insertion so as to provide a support for crimping said organ wall portions against said support element, said crimping support element having: i) a generally cylindrical side-wall; ii) proximal and distal end walls formed generally transversely to said side-wall, thereby to define therewith said crimping support element; iii) a generally axial aperture for providing flow communication therethrough; and iv) an attachment means for operationally engaging said crimping support element to a crimping applicator member so as to position said crimping support element adjacent to said anastomosis ring for facilitating crimping of preselected wall portions of a hollow organ therebetween.
