Delivery systems and methods of implantation for prosthetic heart valves
First Claim
1. A method of deploying an it stented device in an anatomical location of a patient, the stented device comprising a proximal end and a distal end, the method comprising the steps of:
- providing a delivery system comprising first and second stent engagement structures at its distal end, wherein the first and second stent engagement structures each comprise a wire haying a distal end that is coiled for engagement with the first and second structural elements at the proximal end of the stented device, respectively, and wherein the coiled distal end of a first wire includes a first number of windings and the coiled distal end of a second wire includes a larger number of windings than the first wire;
attaching a first structural element at the proximal end of the stented device to the first stent engagement structure and attaching a second structural element at the proximal end of the stented device to the second stent engagement structure;
advancing the stented device to an implantation site; and
sequentially disengaging the first structural element at the proximal end of the stented device from the first stent engagement structure of the delivery system and then disengaging the second structural element at the proximal end of the stented device from the second stent engagement structure.

Abstract
A method of deploying an implantable stented device in an anatomical location of a patient, including the steps of providing a delivery system with first and second stent engagement structures at its distal end, attaching a first structural element of the stented device to the first stent engagement structure and attaching a second structural element of the stented device to the second stent engagement structure, advancing the stented device to an implantation site, and sequentially disengaging the first structural element of the stented device from the first stent engagement structure of the delivery system and then disengaging the second structural element of the stented device from the second stent engagement structure.

10. A method of deploying;
- an implantable stented device having a proximal end and a distal end in an anatomical location of a patient, comprising the steps of;
providing a delivery system comprising a plurality of stent engagement structures at its distal end wherein each of the plurality of engagement structures comprise a wire having a distal end that is coiled for engagement with the proximal end of the stented device, and wherein the coiled distal end of at least one of the wires includes a larger number of windings than at least one of the other wires comprising the plurality of engagement structures; providing a stented device comprising a proximal end, a distal end, and a plurality of structural elements at the proximal end of the stented device; engaging each of the structural elements at the proximal end of the stented device with one of the stout engagement structures; advancing the stented device to an implantation site; and sequentially disengaging the structural elements at the proximal end of the stented device from their respective stent engagement structures of the delivery system. - View Dependent Claims (11, 12, 13, 14, 15)
