Abstract
A delivery system for an implantable stented device having a handle with a plurality of actuation members, each actuation member connected to one or more stent attachment elements, a sheath having a proximal end attached to the handle, and a plurality of tubes extending within the sheath. The stent attachment elements extend from distal ends of the tubes. A first actuation member is configured to move a first stent attachment element proximally toward the handle and a second actuation member is configured to move a second stent attachment element proximally toward the handle, sequentially releasing specific portions of the stented device by causing distal ends of the stent attachment elements to contact an exterior of the distal ends of the tubes, thereby disengaging the first and second stent attachment elements from the stented device.

22. A delivery system for an implantable stented device, comprising:
-
a handle comprising a plurality of actuation members, each actuation member connected to one or more stent attachment elements; a sheath having a proximal end attached to the handle; and a plurality of tubes extending within the sheath, wherein the stent attachment elements extend from distal ends of the tubes, and wherein a first actuation member is configured to move a first stent attachment element proximally toward the handle and a second actuation member is configured to move a second stent attachment element proximally toward the handle, sequentially releasing specific portions of the stented device by causing distal ends of the stent attachment elements to contact an exterior of the distal ends of the tubes, thereby disengaging the first and second stent attachment elements from the stented device. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A method of sequentially deploying an implantable stented device, comprising:
-
inserting a delivery system with the stented device into a body lumen; advancing the delivery system to an implantation location; manipulating a first actuation member on a handle of the delivery system to proximally retract a sheath containing the stented device; manipulating a second actuation member on the handle of the delivery system to proximally retract a first group of stent attachment elements, each stent attachment element being housed within a tube, thereby releasing the first group of stent attachment elements from the stented device by causing distal ends of the first group of stent attachment elements to contact exterior distal ends of the tubes, thereby disengaging the first group of stent attachment elements from the stented device; and manipulating a third actuation member on the handle of the delivery system to proximally retract a second group of stent attachment elements, each stent attachment element being housed within a tube, thereby releasing the second group of stent attachment elements from the stented device by causing distal ends of the second group of stent attachment elements to contact exterior distal ends of the tubes, thereby disengaging the second group of stent attachment elements from the stented device. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41)
