Abstract

A system and method for the installation and operation of a cardiac assist device. Flexible guides are advanced into a prepared space using minimally invasive techniques. A heart pump construct is advanced into position in the pericardial area along the flexible guides. Once in position, the heart pump construct is activated while still engaged with the flexible guides. The flexible guides provide structural integrity to the heart pump construct needed in order for the heart pump construct to function properly. The forces supplied to the heart by the heart pump construct are affected by the presence of the flexible guides. The structure of the flexible guides, the position of the flexible guides and the structure of the heart pump construct are customized to supply the forces needed by a particular heart in order to assist the heart in pumping more efficiently.

Claims (10)

1. A cardiac assist device, for applying controlled forces externally to a heart that improve both the systolic and diastolic functions of the heart, comprising:

a plurality of flexible guides;

an outer shell lined with inflatable membranes;

conduits extending through said outer shell, wherein said plurality of flexible guides extend into said conduits and said outer shell is free to move along said plurality of flexible guides, and wherein said plurality of flexible guides prevent said outer shell from expanding beyond a maximum diameter and collapsing under a minimum diameter when said cardiac assist device acts upon the heart;

wherein said outer shell, said inflatable membranes and said plurality of flexible guides act together to provide said controlled forces externally to the heart that improve both said systolic and diastolic functions of the heart;

further including a base that attaches to said outer shell to form a cup structure, wherein said plurality of flexible guides pass through said base.

2. The device according to claim 1 , wherein said plurality of flexible guides are free to slide through said conduits in said outer shell.

3. The device according to claim 2 , wherein said outer shell is made from elastomeric materials and is collapsible for insertion in vivo.

4. The device according to claim 3 , wherein said outer shell has a collapsed configuration and an operable configuration, wherein said flexible guides maintain said outer shell in said operable configuration.

5. The device according to claim 1 , wherein said outer shell, said inflatable membranes, and said plurality of flexible guides combine to produce said controlled forces when said inflatable membranes are selectively inflated.
