1. An implantable prosthetic device for connection to native heart valve leaflets, comprising:
a spacer body that is configured such that the spacer body can (i) be disposed between native valve leaflets of a heart, (ii) block blood flow through the spacer body from an atrial side of the spacer body to a ventricular side of the spacer body, (iii) block blood flow through the spacer body from the ventricular side of the spacer body to the atrial side of the spacer body, and (iv) divide an orifice between a ventricle and an atrium such that the native heart valve leaflets can (a) open at two sides of the spacer body into two orifices during diastole to allow blood flow from the atrium to the ventricle through the two orifices, and (b) coapt to inhibit blood flow from the ventricle to the atrium during systole;
wherein the spacer body has a proximal end and a distal end;
wherein the spacer body extends radially outwardly as the spacer body extends away from the distal end toward the proximal end;
at least one anchor portion coupled to the distal end of the spacer body, wherein the at least one anchor portion is placed against a ventricular surface of a corresponding one of the native heart valve leaflets; and
a shaft that extends through the spacer body and that is coupled to the at least one anchor portion, wherein the shaft is configured to change the size of the spacer body.
