Abstract

An implantable vascular device comprises an expandable and compressible implant body, a housing, a rotatable member, and a locking member. The housing is coupled to a first end portion of the implant body. The rotatable member is coupled to the housing and to a second end portion of the implant body such that rotating the rotatable member relative to the housing and the implant body expands or contracts the implant body. The locking member is coupled to the rotatable member and configured to move between an unlocked state and a locked state. In the unlocked state, the locking member allows the rotatable member to be rotated relative to the housing and the implant body. In the locked state, the locking member prevents the rotatable member from being rotated relative to the housing and the implant body.
