In a small number of cases left ventricular assist devices, combined with drug therapy, have enabled the heart to recover sufficiently for the device to be able to be removed (explanted). [ 7 ] [ 8 ] Several surgical approaches, including interventional decommissioning, off-pump explantation using a custom-made plug and complete LVAD removal ...
Impella heart pumps are percutaneous microaxial pumps that act as mechanical circulatory support devices in patients in need of hemodynamic support. [11] The pumps are mounted on support catheters and typically inserted through the femoral artery, although axillary and subclavian artery approaches are not uncommon. [12]
VADs are used in patients too old or ill for a heart transplant, or to keep a patient alive until a heart becomes available for transplantation surgery. [5] In December 1995 Thoratec received FDA approval to sell its Thoratec Ventricular Assist Device System, an external blood pump with cannulae connecting the pump to the patient's heart and ...
During a protected percutaneous coronary intervention (Protected PCI) procedure, "the Impella 2.5 heart pump helps maintain a stable heart function by pumping blood for the heart. This gives a weak heart muscle an opportunity to rest and reduces the heart’s workload, preventing the heart from being overstressed by the procedure as coronary ...
Berlin Heart manufactures two types of VADs: implantable and paracorporeal. INCOR is an axial-flow pump for support of the left ventricle. In this system, the pump is implanted directly next to the heart and is connected to the heart by cannula. The blood coming from the heart flows into the INCOR axial pump. [7]

The computer determines when the heart needs a jolt to get back on rhythm and delivers the electrical impulses back through the wires to the electrode, stimulating the heart muscle to contract.
The pacemaker generator is a hermetically sealed device containing a power source, usually a lithium battery, a sensing amplifier which processes the electrical manifestation of naturally occurring heart beats as sensed by the heart electrodes, the computer logic for the pacemaker and the output circuitry which delivers the pacing impulse to ...
