Abstract

Apparatus and methods for an implant are provided. The implant may have a constrained configuration and a relaxed configuration. The implant may include a strut having an end that may be captured by a hub and may define a reference angle in the relaxed configuration. The implant may include a swivel body that may engage a shaft of a delivery cable and may be rotated through the reference angle. The apparatus may include a pusher catheter to push the implant. The delivery cable may engage the implant. The apparatus may include gauge handle that may include a force gauge to indicate the presence of a force acting on the implant. The apparatus may include a bushing that may be fixed to an end of a pusher catheter. The bushing may move along a delivery catheter lumen and may guide the implant to a keyed position at the bushing.
