[Bipolar radiofrequency energy in arteries--the experimental results with a new catheter system].


PURPOSE To evaluate the effects of radiofrequency heated bipolar probes on the human arterial wall. METHODS Under standardised conditions, lesions were set on the inner layer of a piece of human cadaver arterial wall, using a radiofrequency-heated bipolar catheter. These lesions were measured and described both macroscopically and microscopically. Lesion… (More)
