Versatile modular heart pump for non-blood contacting ventricular function augmentation

A method of positioning a construct about ventricles of a heart, comprising:

• providing at least one active panel, wherein each said active panel includes a top edge, and wherein at least one drain port is disposed along said top edge;
• positioning said at least one active panel against the heart;
• providing an apical hub;
• engaging said at least one active panel with said apical hub in vivo;
• advancing said at least one active panel along the ventricles of the heart while suctioning material out of the pericardial cavity through said drain port.

A method of positioning a pump about the heart, comprising:

• providing a modular heart pumping device having a plurality of separate and distinct parts that include a scanning head;
• assembling said plurality of separate and distinct parts about the heart in vivo, wherein said modular pumping device at least partially encircles the heart and said scanning head is oriented to scan the heart when said modular heart pump is assembled about the heart;
• and
• connecting at least some of said plurality of separate and distinct parts to an external pressure drive.
