Problems solved by technology

[0015] To limit this friction, it is possible to slightly increase the radial expansion of the capsule
However, this increases the size of the delivery system and complicates its introduction into the patient's blood network

Embodiment Construction

[0043] A first therapeutic device 10 according to the present invention is shown in Figures 1 to 7 middle. The device 10 is intended to be introduced into a blood flow conduit of a patient.

[0044] Device 10 includes a prosthetic implant 12 for placement within a blood flow conduit, and a system 14 for releasing the prosthetic implant 12 .

[0045] In this example, the prosthetic implant 12 is an internal valve. Implant 12 includes a tubular endoprosthesis 16 , and a prosthetic valve 18 mounted within tubular endoprosthesis 16 .

[0046] as in Figure 7 As seen in , the tubular endoprosthesis 16 consists of a tubular openworked frame 20 with a central axis A-A' comprising a mesh of wires with spring properties. The frame 20 is obtained, for example, by weaving at least one stainless steel wire, from shape memory alloys or polymers.

[0047] Alternatively, frame 20 is obtained by using laser cut tubes or other techniques.

[0048] The frame 20 defines inner and outer pe...

Abstract

The invention relates to a treatment device for a blood circulation conduit. The device includes: a tubular endoprosthesis (16) with a central axis (A-A'), and a release system (14) including a capsule (32) defining an inner volume (72) receiving the tubular endoprosthesis (16) in its contracted condition. The capsule (32) is displaceable with respect to the tubular endoprosthesis (16) along the central axis (A-A') between a position for covering the tubular endoprosthesis (16) and a position for releasing the tubular endoprosthesis (16). The device includes a mechanism (38) for opening the capsule able to be maneuvered in the covering position in order to have the capsule (32) pass from a closed configuration for retaining the tubular endoprosthesis (16) to an open configuration radially expansed for releasing the tubular endoprosthesis (16). The tubular endoprosthesis (16) is able to be kept at least partly retracted in the inner volume (72) upon passing of the capsule (32) from its closed configuration to its open configuration.

Description

technical field [0001] The present invention relates to devices for treating blood flow conduits, said devices comprising: [0002] - a tubular endoprosthesis having a central axis, said tubular endoprosthesis being expandable between a contracted state and an expanded state, [0003] - A system for releasing said tubular endoprosthesis, said system comprising a capsule defining an inner volume for receiving said tubular endoprosthesis in a contracted state, said capsule being inserted relative to said tubular endoprosthesis The prosthesis is movable along the central axis between a position for covering the tubular endoprosthesis and a position for releasing the tubular endoprosthesis. [0004] The device finds particular application in the treatment of heart valves. Background technique [0005] The heart consists of valves located at the outlet of the right ventricle (pulmonary valve and tricuspid valve) and valves located at the outlet of the left ventricle (aortic val...
