[A metallic extractor in vascular surgery (author's transl)].

The authors have studied and perfected a series of 5 metallic extrators based on the extension of steel springs. This resulted in fine probe that can be used both in venous and arterial surgery. The authors have tested that the pressure produced by the springs does not exceed the mechanical resistance of normal vascular walls. It was possible to remove atheromatous fragments or clots, after other techniques had failed. These extractors seem well adapted to their task, that is to improve mechanical disobstruction of vessels.
