Mechanical ventricular assistance assembly

Abstract

Abstract A MECHANICAL VENTRICULAR ASSISTANCE APPARATUS COMPRISED PRIMARILY OF A VENTRICULAR ASSISTOR CUP HAVING A CONFIGURATION GENERALLY CONFORMING TO THE SURFACE CONFIGURATION OF THE VENTRICLES OF THE HEART. THE CUP IS FORMED OF A RIGID OR NONRESILIENT MATERIAL AND INCLUDES A FLEXIBLE LINER OR DIAPHRAGM. THE RIGID OUTER SHELL IS PROVIDED WITH AN OPEN END FOR RECEIVING THE VENTRICLES AND FIRST AND SECOND PORTS FOR SELECTIVE COUPLING TO PRESSURE OR VACUUM SYSTEMS. THE DIAPHRAGM IS SECURED ABOUT THE OPEN END AND IS FURTHER SECURED ADJACENT ONE OF THE TWO PORTS. AT LEAST ONE ELECTRODE IS PROVIDED IN THE REGION OF ONE OF SAID PORTS FOR THE APPLICATION OF SIGNALS TO CARRY OUT FIBRILLATION OR DEFRIBILLATION OF THE HEART. IN THE CASE WHERE IT IS DESIRED TO PROVIDE MECHANICAL ASSISTANCE OF THE HEART PUMPING ACTION IN SYNCHRONISM WITH NORMAL HEART RHYTHM THE ELECTRODE MAY BE EMPLOYED FOR MONITORING THE ELECTROCARDIAC SIGNALS AND HENCE FOR OPERATING THE MECHANICAL PUMPING ACTION IN SYNCHRONISM WITH THE NORMAL HEART RHYTHM. ALTERNATIVELY ADDITIONAL ELECTRODES MAY BE MOUNTED WITHIN THE ASSEMBLY FOR PERFORMING FIBRILLATION AND DEFIBRILLATION FUNCTIONS WHICH ELECTRODES ARE POSITIONED A SPACED DISTANCE AWAY FROM SAID FIRST MENTIONED ELECTRODE AND ALONG SAID DIAPHRAGM.
