Abstract
Embodiments are described herein that relate to prosthetic heart valves, and devices and methods for use in the delivery and deployment of such valves.
Claims (15)
1. A method for delivering a valve, the method comprising the steps:
advancing a guidewire to a desired location within a body, the guidewire having an outer sheath and an inner shaft;
advancing a delivery catheter over the guidewire to the desired location;
mounting a valve capsule onto a proximal end of the guidewire, the valve capsule containing a valve in a compressed configuration, the valve having a central axis and a distal tension arm extending laterally from the valve, the distal tension arm having a guidewire collar, the guidewire collar having an aperture sized to permit the inner shaft of the guidewire to extend through the aperture and to block the outer sheath of the guidewire from extending, through the aperture;
loading the valve capsule into a proximal, end of the delivery catheter;
advancing the valve in the compressed configuration from the valve capsule into a lumen of the delivery catheter such that the central axis of the valve is perpendicular to a lengthwise axis of the delivery catheter and the distal tension arm is distal to the central axis; and
advancing the valve in the compressed configuration through the lumen of the delivery catheter to the desired, location by advancing the outer sheath of the guidewire over the inner shaft of the guidewire.
2. The method of claim 1 , further comprising:
compressing the valve in a first direction that is co-axial with the central axis and in a second direction that is co-axial with a lateral axis of the valve, the lateral axis being perpendicular to the central axis.
3. The method of claim 2 , wherein the valve in an expanded configuration has a first height along the central axis and a first lateral width along the lateral axis, the valve in the compressed configuration has a second height along the central axis that is less than the first height, and a second lateral width along the lateral axis that is less than the first lateral width.
4. The method of claim 3 , further comprising:
deploying the valve in the expanded configuration in an annulus of a native valve between an atrium of a heart and a ventricle of the heart such that a portion of the valve including the distal tension arm is disposed below the annulus in the ventricle.
5. The method of claim 1 , wherein the valve includes a self-expanding valve frame.
6. The method of claim 5 , wherein the valve frame forms a plurality of compressible wire cells having an orientation and cell geometry substantially orthogonal to the central axis.
7. The method of claim 1 , wherein the valve has a long-axis oriented perpendicular to the central axis, the advancing the valve in the compressed configuration from the valve capsule into the lumen of the delivery catheter is such that the long-axis of the valve in the compressed configuration is substantially parallel to the lengthwise axis of the delivery catheter.
