TRANSCATHETER DELIVERY SYSTEMS AND DELIVERY CATHETERS FOR PROSTHETIC MITRAL VALVE DELIVERY, AND METHODS FOR PROSTHETIC MITRAL VALVE DELIVERY USING A RETROGRADE APPROACH
First Claim
1. A heart valve prosthesis delivery system, comprising:
- a delivery catheter comprising i) an elongated tubular component, ii) an arm portion, and iii) an elbow portion coupling the arm portion to the elongated tubular component, wherein when the elbow portion is in a state of flexion, the delivery catheter is in a delivery configuration with the arm portion in a closed state in which the arm portion is substantially parallel with a longitudinal axis of the elongated tubular component; and
a heart valve prosthesis releasably attached to the arm portion.

Abstract
Transcatheter delivery systems, delivery catheters and associated methods for percutaneous delivery of prosthetic mitral valves using a retrograde approach are disclosed herein. A heart valve delivery system configured in accordance herewith includes a delivery catheter having an elongated tubular component and an articulation assembly at a distal end thereof. The articulation assembly includes an arm portion coupled to the tubular component by an elbow or hinge portion. In a closed, delivery state, the elbow portion positions the arm portion generally parallel to the tubular component for delivery of the delivery catheter through the vasculature. In an open, deployed state, the elbow portion positions the arm portion in a non-axial direction with respect to a longitudinal axis of the tubular component for orienting and positioning a prosthetic valve device carried by the arm portion, e.g., within the native mitral valve region.

22. A delivery catheter for intravascular delivery of a heart valve prosthesis to a heart valve of a patient, the delivery catheter comprising:
-
an elongated tubular component having a distal segment and an articulation assembly at the distal segment, wherein the articulation assembly includes an arm portion coupled to the elongated tubular component by an elbow portion, wherein in a state of flexion, the elbow portion positions the arm portion generally parallel to the elongated tubular component for intravascular delivery of the distal segment of the delivery catheter, and wherein in a state of extension, the elbow portion positions the arm portion in an outwardly angled direction with respect to a longitudinal axis of the elongated tubular component.
