  • an implant body; and

    a selectively adjustable, circumferentially expandable and contractible collar attached to a portion of the implant body and having at least one torque transmission shaft that, when rotated, causes either an expanding or contracting configuration change in the collar and the portion of the implant body and, thereby, permits implantation of the implant body within an anatomic orifice to effect a seal therein under normal physiological conditions.
