Device for treating a blood circulation canal and process for preparing this device
First Claim
1. Device for treating a blood circulation canal, of the type comprising:
- a hollow support delimiting, in the vicinity of a distal end, at least one transverse retention opening;
an endoprosthesis which can be deployed between a state retracted against a lateral surface of the support and an expanded state in which the endoprosthesis can be released from the support;
at least one filamentary connection forming a clamping ring surrounding the endoprosthesis and forming a loop engaged in the support through the retention opening;
the clamping ring being extensible between a configuration for maintaining the endoprosthesis in its retracted state and a configuration for deploying the endoprosthesis; and
, for the or each filamentary connection,a retention rod which is mounted to be movable in the support between a position for retaining the loop and a position for releasing the loop;
wherein the retention rod comprises at least one hook for retaining the loop, the displacement of the retention rod from its release position to its retention position bringing about the tightening of the clamping ring from its configuration for deploying the endoprosthesis to its configuration for maintaining the endoprosthesis.

Abstract
This device comprises a hollow support (13) delimiting, in the vicinity of a distal end (19), a transverse retention opening (23A). It comprises an endoprosthesis (11) which can be deployed between a state retracted against the support (13) and an expanded state. The device comprises a filamentary connection (33A) forming a clamping ring (43) surrounding the endoprosthesis (11) and forming a loop (45) engaged in the support (13) through the retention opening (23A). The device comprises a retention rod (31A) mounted to be movable in the support (13). The retention rod (31A) comprises a hook (35) for retaining the loop (45). The displacement of the retention rod (31A) from a release position to a retention position brings about the tightening of the clamping ring (43).
