IMPLANTABLE DEVICE

摘要

The invention relates to an implantable device (1) that comprises a tubular implant (5) that can be expanded between an insertion position, in which it has a tubular configuration, and an implantation position, in which it assumes the configuration of at least one corolla. The implant comprises actuation means (6) for expanding the implant and including: at least a first actuation ring (7) mounted on said implant at a distance D1 from the distal end (8) thereof; an actuation wire (11) extending longitudinally inside said implant and through said first actuation ring (7), and having a front end connected to the distal end (8) of the implant; and at least one blocking part (14) provided on said wire (11) at a distance D2 lower than D1 from the distal end of said implant. Characteristically, the implant is a braid and each ring comprises a portion stiffened by said braid.
