A method of operating a counterpulsation device (CPD) in a human or animal subject is disclosed, the method including: receiving a heart beat signal indicative of the heart beat of the subject; providing counterpulsation therapy by controlling the pressure supplied to a CPD drive line in pneumatic communication with the CPD to cause the CPD to alternately fill with blood and eject blood with a timing that is determined at least in part based on the heart beat signal; while providing counterpulsation therapy, receiving a CPD drive line pressure signal indicative of the pressure in the CPD drive line; and adjusting the pressure supplied to the drive line based at least in part on the drive line pressure signal.

Counterpulsation device driver apparatus, method and system

The present disclosure provides medical devices, systems and methods and in particular to devices and methods useful for anchoring graft materials to bodily structures.

Graft anchor devices, systems and methods

An apparatus is disclosed for attaching a counter pulsation device (CPD) to a blood vessel in a human or animal subject, the apparatus including: an interposition graft having a first end configured to be attached to the blood vessel, a second end, and an interior passage providing fluid connection between the first end and the second end; and a pump graft having first end attached to the second end of the interposition graft, a second end configured to be attached to the CPD, and an interior passage providing fluid connection between the first end and the second end In some embodiments, the interior passage of the interposition graft includes a rough surface configured to promote biological growth on the surface, and the interior passage of the pump graft includes a smooth surface configured to inhibit biological growth on the surface.
