Abstract: This invention relates to a medical device comprising an implant for the treatment of an affection of an anatomical duct. A part of the duct (V) wall is lined on the outside with at least one lining (140′a), essentially facing the proximal and/or distal ends of the implant (100). Means of fastening (361) the lining to the implant apply, through the duct wall, the implant against this duct, and means of setting both the lining and the fastening means allow their positioning around said duct. In particular, application to the treatment of an aneurysm.

Abstract: The invention relates to an assembly using a vascular filter accommodated in an implanting sleeve from which is can be partially expelled in the case of temporary filtration use by means of a maneuvring rod to which the filter is connected in separable manner, so that, in the case of definitive use, the filter is separated therefrom, then being expelled from the sleeve. The filter may have legs in the shape of a corolla and extensions, for retaining it in place in the vessel, which naturally define a cylinder. Use in the treatment of risk of embolism.

Abstract: The invention relates to a device for medical use which is capable of being introduced into a duct of a living human or animal body, said device comprising a biocompatible flexible rod which has an axis along which it extends, free of stress, in a rectilinear manner, said rod having a length along this axis, a distal end and a proximal end. This device is characterised in that in order that the rod should remain substantially at a specific implantation location in the duct it is equipped with at least one means for absorbing axial stresses which is disposed along the axis thereof and is distinct therefrom whilst being connected thereto, such that its proximal end is not substantially displaced axially once the rod has reached the specific implantation location in the duct.

Abstract: A vascular prosthesis adapted to be endoluminally inserted into a vascular region, particularly a vascular region having an aneurysm, and a method for implanting the same. The prosthesis features a tubular framework and a sheath bound to the framework for canalizing the flow of blood, with an extension of the sheath extending beyond a free end of the prosthesis. The sheath extension provides an attachment point for a portion of a blood vessel and/or a vessel substitute to be attached chirurgically to the prosthesis. In a preferred embodiment, the prosthesis constitutes a vascular graft extension that is connected to one of the branching portions of an expandable tubular branching vascular graft.

Abstract: The invention is an assembly for positioning an implant that has an axis and at least one axial tubular region having an inside diameter. More specifically, the assembly positions the implant into an internal passageway in a body, such as a blood vessel. The assembly has two removable elements, both having a predetermined cross-section. At the distal end of the first element of the assembly is a lateral protuberance having a radial length. The assembly is further characterized in that the cumulative cross-section dimension of the two elements away from their distal ends and the radial length of the lateral protuberance are both smaller than the inside diameter of the axial tubular region of the implant.

Abstract: A vascular prosthesis to be implanted by the percutaneous endoluminal route is provided according to an embodiment of the invention. The vascular prosthesis includes a flexible sleeve to channel blood therein, and a tubular armature (or stent) to which the sleeve is connected essentially coaxially, the armature being capable of having a first diameter or a second diameter larger than the first, so that the prosthesis is in the form of a single tube or bifurcated tube assuming a radially constricted state for its percutaneous vascular implantation, or a radially opened out state, once it is vascularly implanted, additionally including a vascularly anastomosable terminal portion of sleeve which extends, or is added onto, the flexible sleeve, beyond the armature, this portion being therefore suitable to be anastomosed, in particular by suture, to at least one vessel or vessel substitute.

Abstract: The catheter is a catheter for controlling the circulation of fluid through it, from or to a vessel in which the catheter is inserted. The catheter comprises a long tubular body that is open especially at its distal end (5), over which there is arranged a cap (5) having an essentially flat distal wall (7) in which there is formed at least one slit forming a valve (7).The slit in the cap has a length that is greater than or equal to the inside diameter of the body of the catheter. The said slit preferably extends also into the side of the cap, and a tube is inserted into the distal portion of the catheter in order to support the sleeve during aspiration.

Abstract: The invention relates to a blood filter that is to be positioned within a blood vessel to trap blood clots. The filter includes a head to which there are attached and from which there extend several legs comprising at least one elongated element having two opposite ends. The legs are radially movable and the elongated element of at least some of these legs has a shape folded back upon itself, substantially in the form of a loop. According to the invention, one of the ends of at least some of these elongated elements is disposed at a distance from the inside of the head of the filter.

Abstract: A covered self-expanding vascular occlusion device and a method of making and using the device. The device comprises a braided wire member with at least two axially spaced securing members affixed to the braided wire member and a thin film covering at least half of the device. The braided member can be moved between a larger diameter ball-like shape or conical shape in its relaxed position, and a smaller diameter cylindrical shape in its stretched position. The film covering is applied to the device by first stretching a portion of film to form a shape similar to a portion of a device to be covered by the film, then inserting the device into the shape formed in the film so that the film covers at least half of the device, and trimming the film to separate the covered device from the remaining film. The device is used by installing it on the end of a tubular introducer where it is held in its relaxed position until needed.

Abstract: An endoluminal medical prosthesis has a frame, a flexible sleeve, and means for fastening the flexible sleeve to the frame. The frame includes a plurality of adjacent, axially-spaced undulating or meandering tubular structures, the undulations or meanders being formed by elongate segments arranged in V- or U-formation, with apices therebetween. The flexible sleeve is substantially coaxial with the frame and channels a fluid flowing in the duct. The attaching element, which includes a flexible thread, wraps around and extends from an elongate segment of one meandering structure of the frame to an elongate segment of an adjacent, axially spaced meandering structure of the frame, preferably passing through the flexible sleeve with each wrap or turn around a segment.

Abstract: A prosthesis which can be implanted in a human or animal duct to ensure a passageway in the duct. The prosthesis is formed from several filaments which have corrugations and which are wound to define a tubular surface. The corrugations form an advantageously zig-zagged series of rings that are stepped along the length of the prosthesis, with corrugated portions of the individual filaments constituting portions of two or more separate ones of the rings.

Abstract: The invention generally relates to an intraluminal medical device, that is to say a device intended to be implanted in a passage in the body. This device has a substantially "filiform" structure with elongated legs (11) which have no hooks for anchoring them to the passage. These legs comprise two portions (11a, 11b). The first portion (11a) which bears against the passage has a flattened and substantially solid surface. At right-angles to the main axis (13) of the device, the maximum dimension of the second portion (11b) is less than that of the first portion.Application particularly to temporary/definitive filters.
