Problems solved by technology

[0014] This kit is not entirely satisfactory
In order to provide adequate fixation of the valve support in the vessel, the collar must have a significant length which increases the length of the valve support and makes its positioning difficult and imprecise

Embodiment Construction

[0036] The first kit 10 according to the invention is in figure 1 with 2 Shown in.

[0037] This kit can be used for implantation, for example, to replace the natural pulmonary valve against the inner wall 12 of the ventricular outflow tract that defines the blood circulation vessel 14.

[0038] The kit 10 includes a valve support 16 that can be used to squeeze against the internal wall 12; and a removable artificial valve 18 that is carried by the valve support 16 to provide a one-way circulation of blood flow in the blood vessel 14.

[0039] The kit 10 further includes a release device (not shown) for the support body 16; and a tool 20 for releasing the valve 18, which can be figure 2 Seen in.

[0040] Such as figure 1 As shown, the valve support 16 includes an outer peripheral wall 22 for rigidly joining the inner surface 12; an inner peripheral wall 24 arranged in the wall 22 to support the valve 18; and a mechanism 26 for connecting the inner wall 24 and the outer wall 26, which ...

Abstract

The kit (10) of the invention includes a valve bearing (16) that can be radially deformed. The bearing (16) includes an outer peripheral wall (22) defining a central passage (40) having an axis (X-X'). The bearing (16) further includes an inner peripheral wall (24) defining an inner lumen (44) having a radial dimension lower than that of the central passage (40). The kit (10) includes a prostheticvalve (18) to be placed on the inner peripheral wall (24). The inner peripheral wall (24) extends in the central passage axially relative to the outer wall (22). The valve bearing (16) includes a means (26) for maintaining the inner peripheral wall (24) radially remote from the outer peripheral wall (22). The inner peripheral wall (24) and the maintaining means (26) define an inner blood circulation region (56) containing the lumen (44) which is tightly isolated from an outer region (58).

Description

Background technique [0001] The present invention relates to a kit for treating blood circulation and blood vessels. This kit includes: [0002] ——Valve support body, which can deform radially between the contracted state and the expanded state, the valve support body includes: [0003] At least one outer peripheral wall for pressing against the wall of the blood circulation vessel, the outer peripheral wall defining a central channel with a central axis; [0004] The inner peripheral wall fixedly engages the outer peripheral wall and defines an inner aperture with a radial diameter, which is smaller than the radial dimension of the central passage; and [0005] A mechanism for keeping the inner peripheral wall at least partially radially spaced from the or each outer peripheral wall; and [0006] -Artificial valves, including shutters, which are radially deformable and are used to be placed in the aperture on the inner peripheral wall to selectively close the aperture; [0007] The reta...
