Improved Device for Sutureless Aortic Anastomosis: Applied in a Case of Cancer
AUTOR(ES)
Aluffi, Alessandro
RESUMO
To reduce the time needed for clamping or circulatory arrest (or both) during substitution of a prosthesis for the thoracic aorta, we developed an expandable device that can be used with any commercially available prosthetic graft to enable sutureless aortic anastomosis. Improvements upon a previous version of the device include the use of nickel-titanium alloy (Nitinol) instead of stainless steel. This, together with an improved wire-looping design, now enables continuous control of diameter, even when the device is in contact with blood. A further improvement consists of 4 metallic hooks on the outer surface, which enable firm fixation to the aortic stump.
