Delivery system for vascular implant
First Claim
1. A medical treatment system for treating a heart valve, the system comprising:
- a delivery device comprising;
a handle;
a first elongate member having a nose cone at a distal end thereof; and
a second elongate member having a ring mounted thereon, the ring comprising at least one slot;
wherein the first elongate member extends through the second elongate member and wherein the first and second elongate members are operably coupled to the handle; and
an implant supporting a heart valve body, wherein the implant comprises;
a self-expanding frame;
proximal anchors extending from the frame configured to be positioned on a first side of a native heart valve annulus; and
distal anchors extending from the frame configured to be positioned on a second side of the native heart valve annulus, the second side being opposite the first side;
wherein a proximal portion of the implant is configured to be connected to the at least one slot in the ring; and
wherein the delivery device further comprises a distal ring comprising a plurality of slots configured to connect to a distal portion of the implantwherein the implant is configured to be positioned at least partially between the ring and the nose cone in a radially compacted configuration during delivery of the implant; and
wherein self-expansion of the frame is configured to cause the proximal anchors and/or the distal anchors to extend radially outward from the frame for engagement with the native heart valve annulus; and
wherein the delivery device is configured to retain the distal portion of the implant in a radially compacted shape.

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.

17. A medical treatment system for treating a heart valve, the system comprising:
-
a delivery device comprising; a first elongate member having a ring mounted thereon, the ring comprising at least one slot; and a suture received within the at least one slot; and an implant supporting a heart valve body, wherein the implant comprises; a self-expanding frame; proximal anchors extending from the frame configured to be positioned on a first side of a native heart valve annulus; and distal anchors extending from the frame configured to be positioned on a second side of the native heart valve annulus, the second side being opposite the first side; wherein the delivery device is configured to retain the implant in a radially compacted configuration; wherein the implant is configured to be connected to the suture, wherein tension on the suture controls expansion of the implant; and wherein self-expansion of the frame is configured to cause the proximal anchors and/or the distal anchors to extend radially outward from the frame for engagement with the native heart valve annulus. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
