Heart and peripheral vascular valve replacement in conjunction with a support ring
An implantable valve replacement system for a cardiovascular valve may include an adjustable stabilizing ring. The stabilizing ring may be composed of a body member that is transitionable from an elongate insertion geometry to an annular operable geometry. The stabilizing ring may further include a plurality of anchors deployable in the annular operable geometry to engage the annulus of the cardiovascular valve. The ring may be used in conjunction with an implantable valve frame. The valve frame may be located within the ring and the ring, in turn, may be stabilized through the anchors engaging the valve annulus. The valve replacement system may be applied by engaging the ring in its annular operable geometry with the valve annulus through the anchors. The valve frame may be inserted through the opening of the ring, thereby forming a stabilizing mechanical contact between the frame and the annulus.
1. A method of stabilizing a malformed cardiovascular valve and replacing the malformed cardiovascular valve, the method comprising:
performing a first medical procedure to treat the malformed cardiovascular valve of a patient comprising:
inserting a distal end of a first catheter, the first catheter comprising a first delivery system, into the malformed cardiovascular valve, wherein the first delivery system is configured to move one or more objects from a proximal end of the first catheter to the distal end of the first catheter;
guiding, via the delivery system, an adjustable stabilizing ring in an elongate geometry from the proximal end of the catheter to the distal end such that the adjustable stabilizing ring transitions to an annular operable geometry upon exiting the distal end of the catheter;
deploying a plurality of anchors from the adjustable stabilizing ring to engage an annulus of the malformed cardiovascular valve;
performing a second medical procedure subsequent to the first procedure and separated in time to replace a natural cardiovascular valve of the patient at the malformed cardiovascular valve with an implantable valve frame, comprising:
inserting a distal end of a second catheter, the catheter comprising a second delivery system, into the malformed cardiovascular valve, wherein the second delivery system is configured to move one or more objects from a proximal end of the second catheter to the distal end of the second catheter;
guiding the implantable valve frame comprising the replacement of the malformed cardiovascular valve through the malformed cardiovascular valve and through a center of the adjustable stabilizing ring;
engaging at least a portion of the implantable valve frame with the adjustable stabilizing ring, thereby stabilizing a position of the implantable valve frame with respect to the malformed cardiovascular valve, wherein engaging at least a portion of the implantable valve frame with the adjustable stabilizing ring comprises expanding the implantable valve frame within the adjustable stabilizing ring thereby forming a mechanical contact between the implantable valve frame and the adjustable stabilizing ring; and
coupling at least one frame anchor of the implantable valve frame to the adjustable stabilizing ring such that the at least one frame anchor engages the adjustable stabilizing ring by partially encompassing the adjustable stabilizing ring,
wherein the at least one frame anchor directly engages an inner circumference of the adjustable stabilizing ring.
2. The method of claim 1 , wherein expanding the implantable valve frame comprises allowing the implantable valve frame to self-expand.
3. The method of claim 1 , wherein expanding the implantable valve frame comprises expanding the implantable valve frame with an expansion device.
4. The method of claim 3 , wherein the expansion device is a balloon.
5. The method of claim 1 , wherein the malformed cardiovascular valve is a cardiac valve.
6. The method of claim 5 , wherein the cardiac valve is a mitral valve.
7. The method of claim 5 , wherein the cardiac valve is an aortic valve.
8. The method of claim 5 , wherein the cardiac valve is a tricuspid valve.
9. The method of claim 5 , wherein the cardiac valve is a pulmonary valve.
10. The method of claim 1 , wherein the malformed cardiovascular valve is a venous valve.
11. The method of claim 1 , wherein the implantable valve frame is D-shape.
12. The method of claim 1 , wherein the implantable valve frame is an angled D-shape.
13. The method of claim 1 , wherein an entire inner surface of the at least one frame anchor is in direct contact with the adjustable stabilizing ring.
