Abstract
An intraventricular pump (IVP) is a surgically-implanted orthotoxic heart pump capable of augmenting either one or both of the heart's ventricles. The IVP pumps blood using an internal diaphragm which is hydrualically activated by a physiologically-controlled pacemaker pump system. The entire system is contained within the human body and is powered by a rechargeable battery system. An artificial valve is incorporated into the right-sided IVP which is hydraulically-activated to work in conjunction with the IVP.
Claims12
A method of augmenting the pumping mechanism of a heart, comprising the steps of:
- forcing hydraulic fluid into a hydraulic access chamber formed between a sac of flexible material for containing blood and an outer shell disposed within a ventricle of the heart to evacuate blood from said sac through an outlet valve of the heart;
- and
- removing hydraulic fluid from the hydraulic access chamber such that the sac may receive blood from an atrium.
A method of augmenting the pumping mechanism of the heart comprising the steps of:
- placing a sac formed of a flexible material and an attached outer shell into a ventricle of the heart, said sac and outer shell forming a hydraulic access chamber therebetween;
- transmitting hydraulic fluid into the hydraulic access chamber to evacuate blood from said sac through an outlet chamber of the heart;
- and
- removing hydraulic fluid from the hydraulic access chamber to receive blood from an atrium into said sac.
