Medical device delivery catheter
First Claim
1. A method of endoluminally deploying a prosthesis, comprising:
- advancing an elongate tubular member through an esophagus and into a stomach of a patient;
positioning a retaining member disposed near or at a distal end of the tubular member proximate to a pylorus of the stomach, the retaining member comprising a resilient material disposed in a constraining manner over a removable prosthesis; and
releasing the prosthesis from the retaining member by actuating from outside the patient the resilient material to extend radially from the retaining member by breaking or tearing a weakened portion of the resilient material within the stomach to release the prosthesis.

Abstract
Apparatus for delivering a medical device to a location in a patient'"'"'s body includes an elongate catheter body having a proximal end and a distal end, a pod coupled with the distal end of the catheter body and adapted to house the medical device during delivery to the location and to open to release the medical device, and at least one distal actuator coupled with at least one of the pod and the medical device. The distal actuator is adapted to promote opening of the pod. A method involves advancing a pod at the distal end of an elongate catheter to the location within the body and activating an actuator coupled with the pod and/or the medical device to cause the pod to open. Opening the pod releases the medical device.
