Abstract
An expandable medical implant is provided with an implantable cage body. The proximal and distal ends of the cage body may each be provided with a tapered or cam portion. The implant may further include a proximal flexure, a distal flexure, a proximal plug member having a tapered portion configured to mate with the tapered portion of the proximal end of the cage body, and a distal plug member having a tapered portion configured to mate with the tapered portion of the distal end of the cage body. The proximal plug member may be configured to move longitudinally such that the distal flexure moves and the circumference of the proximal end of the cage body resiliently expands. The distal plug member may be configured to move longitudinally such that the proximal flexure moves and the circumference of the distal end of the cage body resiliently expands. Methods are also disclosed.
