Abstract
Described is a collapsible atrial cage for percutaneous delivery and implantation of an atrioventricular valve within an atrium of the heart. The atrial cage includes an atrial portion and a ventricular portion. The ventricular portion is attached with and separated from the atrial portion by a valve juncture portion. Notably, the cage includes at least one interlock shaped to lock with and secure an atrioventricular valve proximate the valve juncture portion. Thus, when deployed and expanded, the atrioventricular valve is secured at the atrioventricular juncture.
Claims19
An atrial cage for placement, securing and anchoring of atrioventricular valves, the atrial cage comprising:
- an atrial portion;
- and
- a ventricular portion attached with and separated from the atrial portion by a valve juncture portion.
A method for percutaneously delivering and implantation of an atrial cage, comprising acts of:
- delivering an atrial cage with a delivery system to a desired location inside a subject's heart chamber, such that during delivery, the atrial cage is collapsed within a sheath of the delivery system;
- retracting the sheath to deploy the atrial cage at the desired location, such that upon deployment the atrial cage expands at the desired location;
- delivering a valve with a delivery system to a desired location within the deployed atrial cage;
- and
- releasing and implanting the heart valve at the desired location within the deployed atrial cage.
A method for percutaneously delivering and implantation of an atrial cage having a valve therein, comprising acts of:
- delivering an atrial cage having valve therein with a delivery system to a desired location inside a subject's heart chamber, such that during delivery, both the atrial cage and valve are collapsed within a sheath of the delivery system;
- retracting the sheath to deploy the atrial cage at the desired location, such that upon deployment, both the atrial cage and valve expand at the desired location;
- and
- releasing and implanting the atrial cage with attached heart valve at the desired location.
