Abstract

A medical device delivery system includes a steering catheter including a first steering ring having a plurality of apertures positioned in the wall of the first steering ring. The plurality of apertures are positioned at spaced distances around a circumference of the first steering ring. A first steering cable passes through a first one of the apertures, and a first return cable passes through a second one of the apertures. A second steering cable passes through a third one of the apertures, and a second return cable passes through a fourth one of the apertures. The first steering cable is positioned about 180 degrees from the second steering cable. A handle is operably coupled to a proximal end of the steering catheter. A first control member controls the first steering and first return cable, and a second control member controls the second steering and second return cable.

Dependent claims

A method of implanting a medical device into a native atrioventricular heart valve of a patient, the method comprising:

advancing a distal end of a catheter of a delivery system through vasculature of the patient and into an atrium of a heart of the patient;
while the distal end of the catheter is in the atrium, performing a first steering operation to create a first bend at a first location on the catheter and to deflect the distal end of the catheter toward the native atrioventricular heart valve;
after performing the first steering operation, performing a second steering operation to create a second bend at a second location on the catheter and to raise the distal end of the catheter toward a superior wall of the atrium, the second location being positioned proximally to the first location;
and
after performing the second steering operation, deploying the medical device from the delivery system into or onto the native atrioventricular heart valve of the patient.

A method of implanting a medical device into a native atrioventricular heart valve of a patient, the method comprising:

advancing a distal end of a catheter of a delivery system through vasculature of the patient and into an atrium of a heart of the patient;
deflecting the distal end of the catheter toward the native atrioventricular heart valve in a first steering operation;
raising a height of the distal end of the catheter toward a superior wall of the atrium in a second steering operation while the distal end of the catheter remains deflected;
and
after performing the second steering operation, deploying the medical device from the delivery system into or onto the native atrioventricular heart valve of the patient.

A method of implanting a medical device into a native atrioventricular heart valve of a patient, the method comprising:

advancing a distal end of a catheter of a delivery system through vasculature of the patient and into an atrium of a heart of the patient;
positioning the distal end of the catheter adjacent to the native atrioventricular heart valve so that the medical device has an orientation that is parallel to a longitudinal axis of the native atrioventricular heart valve;
after the distal end of the catheter is positioned adjacent to the native atrioventricular heart valve, and while the medical device is coupled to the delivery system, raising the distal end of the catheter toward a superior wall of the atrium without changing the orientation of the medical device;
and
after raising the distal end of the catheter, deploying the medical device from the delivery system into or onto the native atrioventricular heart valve of the patient.
