摘要：
An implant includes a collar configured for disposal within tissue. The collar defines an axial bore. A shaft extends between a first end and a second end. The shaft is configured for disposal with the bore of the collar. A base defines an axial bore having an inner surface configured for engagement with the shaft such that the base is axially movable relative to the shaft. At least one arm extends between the collar and the base. The at least one arm is movable via axial movement of the base relative to the shaft between a first position and a second position such that the at least one arm is expanded in a configuration to engage tissue. Methods of use are also disclosed.
