Abstract: Device for treating lesions of the wall of blood vessels, in particular false aneurysms, by coagulation, which device comprises an introducer with value and with removable needle, a filament which is able to be introduced into the pocket of this aneurysm and to roll up on itself therein, and a introducing the said filament into the pocket through the introducer.

Abstract: A retractor is mounted at the distal end of a catheter. The retractor is constituted of two symmetrically deformable parallelograms. In the closed position, the retractor has substantially the same radial extension as the catheter.

Abstract: The present invention relates to a device for protected angioplasty, intended for the implantation of luminal endoprosthesis (or stent) in critical areas such as carotid or vertebral arteries, where protection of downstream-situated organs is highly desirable. The device comprises a central stent pusher part comprising a microcatheter bearing at its distal end an atraumatic tip, the atraumatic tip being prolonged by a tip balloon part comprising an inflatable occlusive balloon which may be inflated with a physiologically acceptable fluid at predetermined rates, a fluid-releasing section extending at the proximal the of the occlusive balloon, said releasing section being able to release the fluid from the balloon into an upstream section of the vessel when the pressure of the fluid reaches a predetermined level.

Abstract: A luminal endoprosthesis comprising a framework made up of braided filaments. The framework is self-expanding, that is to say that after it has been radially compressed for positioning of the endoprosthesis, it automatically recovers its nominal diameter. The metal of the framework has undergone a thermal treatment bringing about a state transition, at a temperature close to that of the organism, and this confers upon it a suitable rigidity after it has been positioned in an anatomical conduit.

Abstract: A reversible-action endoprosthesis delivery device (1) comprising an axially extending inner tube (8) surrounded by an outer sheath (16) comprising remote-activated retaining device (20) able to maintain or release the endoprosthesis (7) in a fixed axial relationship relative to the inner tube (8) so that up to the end of the placement procedure, the endoprosthesis (7) can be withdrawn and replaced in a more suitable position.
