Abstract
The invention concerns a vascular occlusion device. The invention is characterised in that it comprises two expandable members (3, 4) enabling it to be fixed by pressure on two portions of the vessel; it further comprises an intermediate part (5) deformable in twisting to an adjustable degree depending on the relative position of the two expandable members (3, 4); thereby producing a maximum constricted region (6) defining the extent of occlusion. The invention also concerns a apparatus for setting and a method for using such a device.
Claims13
Occlusion device (1) adapted to be introduced into a vessel (2) characterized by the fact
- that it comprises two hollow expansible members (3, 4) for its securement by bearing against two portions of the wall of the vessel (2) and an intermediate portion (5), which is hollow and deformable in torsion to a degree adjustable according to the relative positions of the two expansible members (3, 4) to create a zone of maximum constriction (6) defining the degree of occlusion.
