DEVICE FOR TREATING A BLOOD VESSEL

摘要

A device comprises an expandable implant (11) and a hollow stent (13) internally defining a central passage (14). Said hollow stent (13) defines a retention opening (23A) of the implant (11) near the distal end thereof (19). The inventive device also comprises a wire-type link (53A) for releasably fixing the implant (11) to the stent (13), which comprises a traction section (75A) introduced into the opening (23A), and extending inside the central passage (14). For the wire-type link (53A), the device comprises an internal insulation channel (29A) arranged in the central passage (14) and axially fixed with respect to the stent (13). The insulation channel (29A) receives only one wire-type link (53A) and defines a channel (41) which is devoid of a link at least between the proximal end (21) of the stent (13) and the retention opening (23A) and is placed in the central channel (14).
