LENGTH EXTENSIBLE IMPLANTABLE DEVICE AND METHODS FOR MAKING SUCH DEVICES

摘要

A length extensible implantable device includes a porous member and a longitudinal constraining member. The longitudinal constraining member can constrain at least a portion, up to the entire length of, the porous member in the longitudinal direction. The length of the longitudinally constrained portion can be expanded by applying force to the porous member. The porous member may be a porous tubular member.
