Modular valve prosthesis, delivery system, and method of delivering and deploying a modular valve prosthesis
First Claim
1. A delivery system for delivering a modular valve prosthesis, the delivery system comprising:
- an inner shaft;
an outer sheath surrounding the inner shaft, the outer sheath including a capsule at a distal portion thereof, the capsule including a first section, a second section, and a first band disposed between the first section and the second section, wherein the first and second sections comprise a first material and the first band comprising a second material different than the first material, wherein the second material is more flexible than the first material; and
a modular valve prosthesis disposed within the capsule in a radially compressed delivery configuration for delivery to a treatment site, wherein the modular valve prosthesis includes a first module and a second module separated by a first gap such that the first and second modules do not contact each other in the radially compressed delivery configuration, wherein the modular valve prosthesis is disposed within the capsule such that the first module is aligned with the first section of the capsule, the second module is aligned with the second section of the capsule, and the first gap is aligned with the first band of the capsule.

Abstract
A modular valve prosthesis includes an inflow stent, a valve component including a valve stent and a prosthetic valve, and an outflow stent. In a radially compressed delivery configuration, an inflow end of the valve stent is separated from an outflow end of the inflow stent and an outflow end of the valve stent is separated from an inflow end of the outflow stent. In a radially expanded deployed configuration, the inflow end of the valve stent is in contact with the outflow end of the inflow stent and the outflow end of the valve stent is in contact with the inflow end of the outflow stent. A delivery system includes a capsule including first, second and third sections and flexible first and second bands between respective sections. The modules of the modular valve prosthesis are aligned with the sections and gaps between the modules are aligned with the bands.
