摘要： A lymph conduction system implant (10) includes a stent graft (12) and a porous membrane (14). The stent graft has a non-porous tubular side wall (16) with a proximal end (18) and a distal end (20). The non-porous tubular side wall is configured to define a lumen having an inflow port (24) at the proximal end (18) and an outflow port (26) at the distal end (20). All exposed surfaces of the stent graft are made of a first biocompatible material. The porous membrane (14) is connected to the proximal end of the non-porous tubular side wall of the stent graft and is configured to span an entirety of a transverse area of the inflow port of the lumen of the stent graft. The porous membrane is made of a second biocompatible material. In a preferred embodiment the porous membrane (14) is configured as a drug eluting porous membrane that carries a drug.

摘要： The invention relates to a mechanical prosthetic heart valve (10) comprising an annular support (12) having an internal peripheral wall (14) centered about a longitudinal axis (X) and delimiting an internal passage, and at least two mobile leaflets (40), preferably three leaflets (40), arranged in such a way as to each be able to effect a rotational movement about an axis of rotation perpendicular to said longitudinal axis (X) so that the valve (10) can pass from a closed configuration to an open configuration and vice versa. Each leaflet comprises a central part (46), and two lateral winglets (48a, 48b) flanking the central part (46) symmetrically with respect to a plane of symmetry (Z) of the leaflet. Each winglet (48a, 48b) comprises one of two terminal portions (49a, 49b). The annular support (12) comprising two opposite edges (26, 28) and as many extensions (30) as the number of leaflets, which extend axially from one of the opposite edges (26, 28), a profiled recess (32) being created on two opposite sides of each extension (30), the recesses (32) acting as guide surfaces for the respective terminal portions (48a, 48b) of each leaflet (40) as the valve (10) passes from an open configuration to a closed configuration, and vice versa. A contact zone of each leaflet (40) in the open position with the internal peripheral wall (14) is less than 15% of the total width of the leaflet (40) extending between the extremities of the two terminal portions (49a, 49b).
