An annuloplasty ring has a non-planar shape and different lateral flexibilities at different points as one proceeds annularly around the ring. Each of the well sections has at least one mating feature allowing it to be joined to at least one other well section and to form a liquid tight seal. An upper surface of the donor wafer is bonded to an upper surface of a handle wafer. The docking connector also includes specific keying arrangement to prevent noncompliant connectors from being plugged in, and thereby minimizes potential damage to the multi-communication device. The apparel may be reversible such that either the first surface or the second surface of the substrate faces outward. In particular, the battery could be recharged while the user sleeps in a bed containing an induction coil.
