Abstract

The clip consists of two separate branches, the facing surfaces of which have profiles which allow the pressure effecting occlusion of the oviduct or vas deferens to be generated only in two separate pressure zones while a cavity is formed as nutrition zone between the two pressure zones to relieve the oviduct or vas deferens of pressure and enable its tissue to be nourished. The branches are connected with one another at both ends by detent closure means.
