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

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.

Abstract: The invention relates to a device for implanting a medical prosthesis in a duct of a human or animal body.Thin device comprises a tubular sheath, suitable for containing a prosthesis to be implanted, and a rod for controlling the prosthesis, which rod may slide in the interior of the sheath. The sheath and/or the rod is(are) provided on at least one part of its (their) length with flexible centring means suitable for acting on the profile of the axial line of the sheath, while restricting its distal end to align itself substantially with the axis of the duct when the sheath is disposed therein.The application of the invention is most particularly in the field of blood filters which can be implanted in a blood vessel.

Abstract: An operating handle for the relative sliding of a tubular sheath and a push-stem. The handle includes a hollow body with two opposite ends between which the stem extends axially. A carriage is detachably connected to the sheath and is movable within the body along an axial direction, and a control device is provided for controlling movement of the carriage. The control device includes a pivoting lever which causes the relative axial displacement of the sheath and stem. The invention finds particular application in the medical field for the implantation of medical devices such as blood filters.

Abstract: The invention relates to a blood filtration device which can be implanted in a patient's body and comprises a catheter and a blood filter secured to one end thereof. The catheter has a longitudinally variable rigidity, being stiffer at its end where the filter is secured thereto and more flexible at the opposite end where the catheter can be connected to an implantable chamber adapted for distributing a drug in the patient's body.

Abstract: The invention relates to an implantable blood filter comprising a self-expanding external structure made from a zigzagged thread wound on itself in order to exhibit a closed configuration. A central strainer section is connected to the said thread at various points for the retention of possible blood clots. This strainer section may be made from a biologically absorbable material. Applications include the production of medical blood filters, which are self-centering and absorbable.

Abstract: The filter includes a plurality of resilient fingers (2) which can be unfolded and are provided at their free ends with centering and bearing runners (5) for engaging an interior wall of a blood vessel. In accordance with a preferred embodiment of the invention, the fingers and the runners consist of flexible wires that are assembled with groups of two adjacent fingers being joined by a wire part folded in the shape of a hairpin.
