Definitions
- the present invention relates to a device for placing a seal around an implant in a blood circulation passage, comprising:
- a hollow sheath having a longitudinal axis
- At least one release member deployable relative to the sheath between a retracted position in the sheath and a position extracted from the sheath.
- This device is particularly applicable to the treatment of heart valves.
- the heart has valves that are present at the exit of the right ventricle (pulmonary valve and tricuspid) and the left ventricle (aortic and mitral valve).
- valves provide unambiguous flow of blood, avoiding blood reflux after ventricular contraction.
- valves may suffer from calcification thus allowing reflux or regurgitation to the ventricle or atrium that has expelled blood flow.
- the problem of regurgitation leads to an abnormal dilation of the ventricle which eventually produces heart failure.
- the valve includes a number of sheets lower than that generally observed for this type of valve, which can affect its operation in the long term.
- This endovalve comprises a tubular stent formed by an autoextensible lattice and a flexible closure or valve made most often in a tissue of animal origin.
- the flexible obturator is fixed permanently in the stent.
- Such endovalves are implantable endoluminally, which considerably limits the risks associated with the implantation of the valve, especially in terms of mortality.
- endovalves are not completely satisfactory after implantation. Indeed, although the outer surface of the stent applies spontaneously against the seat of the native valve, by plating the leaflets between the seat and the outer surface of the stent, leakage may remain around the outer surface of the stent. the endoprosthesis, especially at the commissures defined between the leaves of the native valve. These leaks occur in more than 50% of patients who have had such an operation.
- US 2005/0283231 discloses an implant comprising a stent and a prosthetic valve fixed in the stent. The stent prosthetic valve leaflets are extended by collapsible sections around the stent to interpose between the duct wall and the outer surface of the stent. These sections folded around the stent are able to fill at least in part the leakage that may occur around the valve.
- each section is linked to the valve. It is therefore difficult to position it precisely, in particular vis-à-vis the stent and / or the blood circulation conduit in which the implant is disposed. In particular, the position at which the folded section is to be disposed in the native valve is difficult to determine to ensure a good seal around the stent.
- the exact position of the commissures defined by a native valve varies from one patient to another.
- the foldable sections are not necessarily adapted to the particular morphology of some patients.
- An object of the invention is therefore to obtain a treatment device comprising an implant that can be implanted in a sealed manner in a blood circulation conduit, the seal being easily and adaptably made to the anatomical configuration of the patient.
- the invention relates to a device of the aforementioned type, characterized in that the device comprises, for the or each release member, a sealing body having an angular extent strictly less than 360 ° around the longitudinal axis, the sealing body being releasably fixed on the release member to be released from the release member.

- each release member comprises a plurality of release members spaced angularly from each other about the longitudinal axis, each release member carrying a sealing body releasably fixed on the release member to be released from the release body;
- a releasable retaining member of the or each sealing body on the release member the releasable retaining member being movable relative to the sealing body between a configuration engaged with the sealing body and a release configuration of the sealing body;
- the release member defines an inner channel, the releasable retaining member being disposed at least partly in the inner channel; in the extracted position, the or each release member has a flared distal portion protruding transversely beyond the sheath, the flared distal portion advantageously having a first section deviating from the longitudinal axis and a second section parallel to the sheath; the longitudinal axis or approaching the longitudinal axis;
- - It comprises a closure assembly of the sheath comprising a central stent disposed at least partly in the sheath and a nose mounted at the distal end of the central stent, the or each release member being disposed at least partly between the sheath and the central guardian;
- the closure assembly is movable between a proximal position of closing the sheath and a distal opening of the sheath, wherein the or each release member is adapted to move from its retracted position to its extracted position;
- the closure assembly is movable from the distal position, when the or each release member occupies its extracted position, to an intermediate transverse spacing position of the or each sealing body, in which the nose cooperates with each release member to move it transversely away from the longitudinal axis;
- Each release member is slidably mounted on the guardian
- the or each sealing body comprises a block of flexible material, preferably foam, and a rigid central frame, disposed in the block of flexible material.
- the sheath does not contain an implant intended to be implanted in a passage of blood circulation between the or each sealing body.
