Nonsurgical placement of arterial endoprostheses: a new technique using nitinol wire

Radiology. 1983 Apr;147(1):261-3. doi: 10.1148/radiology.147.1.6828742.


A new type of endovascular prosthesis has been developed using a unique metal alloy (nitinol) with a heat-sensitive memory. Nitinol wire coil grafts were straightened in ice water and passed into the canine aorta via catheter, where they reformed into their original shapes. Follow-up aortograms demonstrated long-term patency with minimal thrombus formation. Nitinol endovascular coil grafts may eventually be used in the nonsurgical treatment of several forms of vascular disease.
