Abstract
An implantable distraction device includes a tubular member oriented along a longitudinal axis, and curved first and second attachment members coupled to the tubular member and configured to be sutured within a body lumen. The second attachment member is spaced apart from the first attachment member along the tubular member. The device further includes at least one magnet coupled to the tubular member and movable relative to the tubular member. At least one of the first attachment member or the second attachment member is axially movable relative to the other to vary an axial distance between the first and second attachment members. The at least one magnet is configured such that motion of a magnetic field relative to the distraction device causes corresponding motion of the at least one magnet, and corresponding motion of one attachment member relative to the other.
