Abstract: Replacing a defective atrioventricular heart valve, in particular a tricuspid valve, may include stent devices, prosthetic heart valves, delivery systems, and corresponding methods, which provide an improved fixation without distortion of the native anatomy. A stent device for a prosthetic heart valve has an axially extending mesh-shaped body, configured to fit an orifice and defining an inner channel as a passageway from a proximal to a distal end. At least three outer support arms extend from the distal end of the body towards the proximal end. Each support arm has a distal end first support region and a proximal end second support region. The second support region extends radially outwards in the deployed state. Each support arm has a flexible region between the first and second support regions, which is formed as an axially tapered section of the support arm and/or each support arm is tapered towards the proximal end.

Abstract: The present invention relates to an assembly for the tricuspid orifice of a human heart, comprising an external frame (100) connected to an internal stent (200) carrying a tricuspid valve bioprosthesis (210) and a sealing skirt (610). The external frame (100) is configured to hold its position in the native tricuspid annulus. The internal stent (200) is connected to the external frame by one or more fixing strands. The sealing skirt (610) covers the interstitial space existing between the external frame (100) and the internal stent (200). Developments are described which comprise in particular the use of a deformable region of the frame, various alternative embodiments of the sealing skirt, the use of a frame composed of multiple sub-sections, the use of fixing strands between the stent and the frame and of fixing elements for fixing the assembly to the native tissue, the use of sensors and/or actuators, and also the use of a stent in the inferior vena cava. Method aspects are described.

Abstract: The invention relates to a system for treating lesions on a blood vessel bifurcation presenting a first branch (B1) and a second branch (B2), said system comprising: a first endoprosthesis (100) designed to be positioned in the first branch; a second endoprosthesis (200) designed to be placed in the second branch (B2) by engagement through an orifice (140) of the first endoprosthesis (100) once said orifice (140) has been dilated; and an insertion instrument (400) which has a longitudinal axis (1) and which comprises: a first balloon (500) designed to be introduced into the second branch through the orifice (140) of the first endoprosthesis (100) and to dilate said orifice (140); and a second balloon (600) which is aligned with the first balloon (500) along the longitudinal axis (1) and which is designed to receive the second endoprosthesis (200) and dilate it.

Abstract: An endoprosthesis for the treatment of blood vessel bifurcation stenosis. The endoprosthesis comprises three tubular sections and two connections. A distal section is aligned at least approximately with a proximal section. The first distal section is intended for insertion into a first blood vessel branching off on the bifurcation. The first distal section is linked to the proximal section by a first lateral connector. A second distal section, located at the side of the first distal section, is intended for insertion into a second vessel branching off from bifurcation. The two distal sections have their proximal ends linked by a second connector.

Abstract: An endoprosthesis for the treatment of blood-vessel bifurcation stenosis. The endoprosthesis comprises three tubular sections (110, 120 and 140) and two connectors (130 and 150). A distal section (120) is aligned at least approximately with a proximal section (110). The first distal section is intended for insertion into a first blood vessel (T2) branching off on the bifurcation. The first distal section (120) is linked to the proximal section (110) by a first lateral connector (130). A second distal section (140), located at the side of the first distal section (120) is intended for insertion into a second vessel (T3) branching off from the bifurcation. The two distal sections (120 and 140) have their proximal ends linked by a second connector (150).

Abstract: The present invention relates to an anti-pulmonary embolism filter of the pe made of a remanent spring effect resilient wire, characterized in that it is shaped into a spiral (1) having three non-touching turns (2, 3, 4) with the middle turn (3) having a diameter (d3) greater than the diameters (d2, d4) of the other two turns, and in that this diameter (d3) is selected to be close to the half-circumference of the vena cava in the zone where the filter is to be implanted so as to ensure that the function of holding the filter in place by flattening of the vena cava is optimized.

Abstract: The invention describes a pulmonary embolism prevention filter of the type made from an elastic wire with remanent spring effect, characterized int hat it comprises at least two wires (100, 200), each spirally shaped. The said two wires (100, 200) have at least substantially the same length and are connected in the vicinity of their ends.
