DELIVERY SYSTEM FOR VASCULAR IMPLANT
First Claim
1. A method of delivering a self-expanding vascular implant to a native valve, comprising:
- delivering a self-expanding vascular implant on a delivery system to a native valve, the delivery system retaining the vascular implant in a radially compacted configuration;
allowing the self-expanding vascular implant to expand and moving distal anchors extending from the self-expanding vascular implant into engagement with an annulus of the native valve while the proximal end of the self-expanding vascular implant remains connected to the delivery system; and
after engaging the annulus of the native valve, releasing the proximal end of the self-expanding vascular implant from the delivery system.

Abstract
A medical treatment system and method of treatment is described having an implant that can be positioned and deployed, then undeployed to allow repositioning of the implant. The system includes a self-expanding medical implant that longitudinally foreshortens upon radially expanding from a radially compacted state, a distal interface configured to attach the implant to a distal mount of a delivery device, and a proximal interface configured to attach the implant to a proximal mount of the delivery device. Moving the distal mount longitudinally away from the proximal mount applies a longitudinal tension to the implant causing the implant to expand longitudinally and contract radially, and moving the distal mount toward the proximal mount reduces a longitudinal tension in the implant allowing the implant to expand radially toward a fully expanded state.
