Claim Text:
1. A system for the treatment of conditions affecting a native mitral valve, the native mitral valve having a native annulus and native leaflets, and the system comprising: a proximal stabilizing structure having a first pair of first arm members pivotally coupled to a second pair of second arm members at joints between individual first arm members and individual second arm members to move between a low-profile axially-elongated configuration positionable in the lumen of the catheter and a laterally-elongated configuration in which the proximal stabilizing structure is configured to engage tissue of a native valve, wherein, in the laterally-elongated configuration, (a) the joints are spaced laterally apart from each other by lengths of the first and second arm members, and (b) each second arm member has a lower surface configured to extend along and engage a periphery of an atrial surface of the native mitral valve annulus; and a distal stabilizing structure having a third pair of third arm members pivotally coupled to a fourth pair of fourth arm members at joints between individual third arm members and individual fourth arm members to move between the low-profile axially-elongated configuration and the laterally-elongated configuration in which the distal stabilizing structure is configured to engage tissue of the native valve, wherein, in the laterally-elongated configuration, (a) the joints are spaced laterally apart from each other by lengths of the third and fourth arm members, and (b) each third arm member has an upper surface configured to extend along and engage a periphery of a ventricular surface of the mitral valve annulus behind the leaflet;
