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 the native valve, the delivery system retaining the vascular implant in a radially compacted configuration, wherein the delivery system comprises a ring mounted on an elongate support member, the ring comprising at least one slot, and wherein a suture received in the at least one slot extends from the ring and connects to the implant;
allowing the self-expanding vascular implant to expand, wherein tension on the suture controls expansion of the implant; and
moving at least one of proximal and distal anchors extending from the self-expanding vascular implant into engagement with an annulus of the native valve while the self-expanding vascular implant remains connected to the delivery system, wherein the self-expansion of the vascular implant causes the proximal and distal anchors to extend radially outwardly and to move closer to each other to grasp at least one side of the annulus of the native valve between the distal anchors and proximal anchors.

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.

10. 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 the native valve, the delivery system retaining the vascular implant in a radially compacted configuration, wherein the delivery system comprises a first elongate member having a ring mounted thereon, the ring comprising at least one slot, and a second elongate member extending through the first elongate member having a nose cone at a distal end thereof, wherein a proximal portion of the implant is connected to the at least one slot in the ring and the implant is positioned at least partially between the ring and the nose cone; allowing the self-expanding vascular implant to expand; and moving at least one of proximal and distal anchors extending from the self-expanding vascular implant into engagement with an annulus of the native valve such that the proximal anchors are located on a first side of the native valve annulus and the distal anchors are located on a second side of the native valve annulus opposite the first side. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
