Abstract: A method of controlling an external counterpulsation apparatus includes selecting a patient treatment pressure; outputting a signal corresponding to the selected treatment pressure; detecting a pressure of a compressed fluid reservoir; comparing the selected treatment pressure to the compressed fluid reservoir pressure; and controlling a pressure regulator valve based on a difference between the patient treatment pressure and the compressed fluid reservoir pressure. The compressed fluid reservoir pressure may be decreased when the compressed fluid reservoir pressure is greater than a preset difference from the patient treatment pressure, particularly by venting the compressed fluid reservoir to atmosphere. The compressed fluid reservoir pressure may be necessary when the compressed fluid reservoir pressure is less than a preset difference from the patient treatment pressure, particularly by operating a compressor.

Abstract: An external counterpulsation apparatus and method for minimizing end diastolic pressure includes a fluid distribution assembly interconnecting a plurality of inflatable devices adapted to be received about the lower extremities of the patient and a source of compressed fluid to be distributed by the fluid distribution assembly to the inflatable devices. The controller in communication with the fluid distribution assembly controls inflation and deflation of the inflatable devices to minimize end diastolic pressure. The controller controls deflation of the inflatable devices without reducing venous return and then minimizes energy spent in ventricular isovolumetric contraction. Further, the controller controls inflation of the inflatable devices to inflate a distal inflatable device prior to inflating a proximal inflatable device.

Abstract: The present invention provides a high efficiency external counterpulsation apparatus having accurate and reliable timing of inflation and deflation and reduced temperature of the pressurized gas, such that the gas flow temperature of the inflatable devices is near to room temperature, as well as faster and more responsive inflation/deflation equipment. The external counterpulsation apparatus includes a plurality of inflatable devices received about the lower extremities of the patient, a source of compressed fluid in communication with said plurality of inflatable devices, and a fluid distribution assembly interconnecting said source of compressed fluid and said inflatable devices. The fluid distribution assembly includes a selectively operable inflation/deflation valve interconnected between each of said inflatable devices and said source of compressed fluid. The fluid distribution assembly separately operates each inflation/deflation valve to sequentially inflate and deflate each inflatable devices.

Abstract: A heart failure treatment method includes administering external counterpulsation therapy sessions to a subject from about 10 to about 80 days. Each counterpulsation therapy session is preferably from about 20 to about 90 minutes. Administering external counterpulsation therapy includes providing pressure devices adapted to be received about the lower extremities of the subject, interconnecting a source of compressed fluid with the pressure devices, interconnecting a fluid distribution assembly with the pressure devices and the source of compressed fluid, distributing compressed fluid from the source of compressed fluid to the pressure devices, providing a controller in communication with the fluid distribution assembly, and inflating and deflating the pressure devices using the controller so as to minimize end diastolic pressure.

Abstract: The present invention provides an external counterpulsation apparatus and computer-implemented system for recording patient information for a patient who is receiving treatment from an external counterpulsation device. A patient treatment data structure stores treatment information for one or more patients receiving treatment and a computing device connected to the external counterpulsation device controls operation of the external counterpulsation device and receives the treatment information. The patient data structure also may store demographic information for one or more patients receiving treatment. The computing device receives the treatment information and patient demographic information, and stores the received information in the patient data structure. The computing device is able to output and communicate the treatment information and patient demographic information.
