A pin array is connectively disposed between a surface region of a heat sink and a surface region of an entity to be cooled. Cooling fluid flows between the heat sinks surface region and the entitys surface region, the fluid flowing adjacent each surface region and through the space occupied by the pins, the fluid thereby being agitated by the pins. Frequent inventive practice attributes the pins with supportability of the entity. The pins can be made to be thermally nonconductive, the heat transfer thus being primarily founded on thermally convective principles involving the cooling fluid, the invention thus being effective in the absence of significant heat conduction from the entity to the heat sink. Typical inventive practice prescribes that a given array is patterned in an orderly fashion, all pins therein are parallel and each pin therein has the same cross-sectional geometry; however, there can be disparity between or among pins in any or all such respects. A pins cross-sectional geometry can describe any shapeârectilinear, curvilinear or some combination thereof.

A buoy system for treating cardiac valve regurgitation comprising a movable plug having atrial and ventricular ends, wherein a through-hole passes from the atrial to the ventricular end, wherein during systole, the plug travels toward a cardiac atrium, wherein during diastole, the plug travels into a cardiac ventricle; a tether having atrial and ventricular ends, wherein the tether passes through the through-hole of the moving plug, wherein the atrial end of the tether projects into an atrium, wherein the atrial end of the tether includes a cap to engage a delivery tool; at least one distal anchor located in the ventricle, wherein the distal anchor is coupled to the ventricular end of the tether, and wherein the system is percutaneously delivered and optionally recaptured via catheter and recapture tool at the cap of the tether, respectively.
