Abstract: An orientable catheter (10, 110, 210) comprising a first tubular body (16, 116, 216) having a distal portion with shape memory (26, 126, 226) which is curved at rest, and a second tubular body (38, 138, 238) having a distal stiffening portion (54, 154, 254) forming a stiffening element capable of sliding relative to the first tubular body (16, 116, 216) between a stiffening position in which the stiffening element (54, 154, 254) imposes a straightened configuration on the distal portion with shape memory (26, 126, 226), and a retracted position in which the stiffening element (54, 154, 254) does not interfere with the resting curved configuration of the distal end with shape memory (26, 126, 226).

Abstract: Surgical forceps for removing varicose veins with surgical forceps and related methods are provided. The surgical forceps comprise an elongate tubular sheath, two jaws mounted movably relative to each other around a pivot axis at a distal end of the tubular sheath, two maneuvering branches each having a ring for the insertion of a finger, and a linkage for transmitting the movement of the maneuvering branches to the jaws. The method comprises inserting a finger in each ring, introducing the surgical forceps into a patient's skin, and moving the maneuvering branches towards one another to move the jaws to a gripping position to grip the varicose veins.

Abstract: The invention relates to surgical forceps used for the extraction of varicose veins and having: —a body with an articulation plate (4) and an elongate tubular sheath (1); —two manoeuvring branches (2a, 2b) mounted on the articulation plate (4) and movable relative to each other between an open position and a closed position, each of these branches (2a, 2b) having a ring (5a, 5b) for the introduction of a finger; —a gripper (3) mounted at the distal end of the tubular sheath (1) and having two jaws (7a, 7b) mounted movably relative to each other about an axis A between an open position and a gripping position, the inner faces of said jaws (7a, 7b) being toothed in order to hold the varicose veins; and—means for transmitting the movement of the manoeuvring branches (2a, 2b) to the jaws (7a, 7b), via the tubular sheath (1), said means being designed to move the jaws (7a, 7b) to their gripping position when the manoeuvring branches (2a, 2b) are closed together.

Abstract: Disclosed is a surgical clip for end-to-end or end-to-side vascular anastomosis and for suturing blood conduits, which comprises a V-shaped base from which at least two branches project in a direction opposed to an apex of the V-shaped base. The branches each have a hook pointing toward the base, the branches are parallel to one another before plastic deformation and each branch forms with the corresponding hook a re-entrant corner with an apex angle of between 30° and 80°. The clip has three zones of preferential deformation, at an the apex of the V-shaped base and at connecting zones between the base and the branches. After plastic deformation, the two branches remain substantially parallel. The deformation of the clip has been concentrated on the apex of the base, the angle of which has narrowed under the stress of the gripper, and on the apices, which have opened.

Abstract: The invention concerns a device to inject and/or to take a sample, with the aid of a needle, of a liquid inside the organism of a living being, through the skin in a repeated manner. More particularly, the present invention concerns a device intended to be implanted inside a living, human or animal organism, presenting a vascular system and a skin, to exchange a liquid with the vascular system, through the skin and in a repeated manner, using a needle, the aforementioned device including at least a first tubular puncture site, shaped to be able to be perforated numerous times over all its length, the tubular puncture site being linked up in a watertight manner with a flexible link conduit with the vascular system, the tubular puncture site including an watertight flexible tubing, supported by reinforcement constituted by rigid rings, this being shaped to allow the puncture site to lose its shape to follow the body movements of the patient without causing discomfort.

Abstract: The invention relates to a clip for vascular anastomosis, which makes it possible to perform the anastomosis on blood vessels of any type, including the largest, without perforating the tissues and therefore without causing clot formation. The anastomosis clip according to the present invention also makes it possible to perform the anastomosis rapidly and in a manner that is easy for the surgeon. The invention also relates to a method for the apposition of tissues using such a clip. The clip according to the present invention is plastically deformable and it comprises a base (12) from which at least two branches (10, 11) project, said branches each having an internal face which has a hook (15, 16) pointing downwards (12). These hooks enable anchoring the clip in the vascular walls to be sutured, without, however, perforating them, in order to keep the clip in place, even in the presence of high pressures as is the case in the large-diameter vessels.
