Articulatable prosthetic valve
First Claim
1. Apparatus, for use with a native atrioventricular valve between an atrium and a ventricle of a heart of a subject, the apparatus comprising:
- a delivery tool, comprising;
a rod, transfemorally advanceable to the heart, and having a proximal portion, a steerable distal portion, and an intermediate portion therebetween; and
an extracorporeal rod-controller; and
an implant implantable at the native atrioventricular valve, the implant, comprising;
a first frame, compressed onto the distal portion,a second frame, compressed around the distal portion in tandem with the first frame, and articulatably coupled to the first frame, anda valve member, disposed within the second frame,wherein;
the implant is configured to serve as a prosthetic atrioventricular valve between the atrium and the ventricle, such that the valve member facilitates one-way blood flow from the atrium, via the first and second frames, to the ventricle,the extracorporeal rod-controller is;
coupled to the proximal portion of the rod, andoperably coupled, via the intermediate portion of the rod, to the distal portion of the rod such that operating the extracorporeal rod-controller steers the steerable distal portion of the rod at at least a longitudinal site of the distal portion, causing articulation between the first frame and the second frame, andthe delivery tool is configured to implant the first frame and the second frame at the native atrioventricular valve.

Abstract
A rod (508) is transfemorally advanceable to the heart. An implant (460) comprises (i) a first frame (462), compressed around a first longitudinal site of a distal portion of the rod, (ii) a second frame (464), compressed around a third longitudinal site of the distal portion, (iii) a valve member (50), disposed within the second frame, and (iv) a flexible sheet (466), coupling the first frame to the second frame, and disposed around a second longitudinal site of the distal portion, the second longitudinal site being between the first longitudinal site and the third longitudinal site. An extracorporeal controller (569) is coupled to a proximal portion of the rod, and is operably coupled to the distal portion of the rod. Operating the controller bends the distal portion of the rod causing articulation between the frames. Other embodiments are also described.
