Device for treating a blood circulation conduit and method of preparing this device

摘要

The device has a endoprosthesis (11) deployable between a retracted state and a dilated state in which the endoprosthesis is liberated from a hollow stent (13). A retaining rod including a hook (35) is movably mounted in the stent between a retaining position of a grommet (45) and a liberation position of the grommet. The rod is displaced from its liberation position toward its retaining position that provokes tightening of a tightening buckle (43) from a deployment configuration of the endoprosthesis toward a maintenance configuration of the endoprosthesis. An independent claim is also included for a method of manufacturing a device.
