Estimating the term…
In one embodiment described in the specification, a surgically implantable reciprocating pump employs a check valve as the piston, which is driven by a permanent magnet linear electric motor to assist either side of the natural heart. The pump is implanted in the aorta or pulmonary artery using vascular attachment cuffs such as flexible cuffs for suturing at each end with the pump output directly in line with the artery. The pump is powered by surgically implanted rechargeable batteries. In another embodiment, pairs of pumps are provided to replace or assist the natural heart or to provide temporary blood flow throughout the body, for example, during operations to correct problems with the natural heart.
A monitoring arrangement for monitoring and controlling a device implantable in a human body comprising a secondary coil which is encapsulated in a material which does not substantially attenuate magnetic flux and is locatable internal to a human body wherein the secondary coil is connected to the device, a primary coil locatable external to a human body which transmits electromagnetic energy by electromagnetic carrier waves to the secondary coil, thereby inducing electric current in the secondary coil for supplying power to the device, and an electrical circuit locatable external to a human body for modulating the electromagnetic carrier waves transmitted to the secondary coil, the device comprising a detection circuit for detecting signals induced by modulation of the electromagnetic carrier waves transmitted to in the secondary coil.
A method for monitoring and controlling a device implantable in a human body comprising the steps of:
A monitoring arrangement for monitoring and controlling a device implantable in a human body comprising a secondary coil locatable internal to a human body connected to the device, a primary coil locatable external to a human body which transmits electromagnetic energy by electromagnetic carrier waves to the secondary coil and magnetic means having at least two sides wherein the secondary coil is located on one side of the magnetic means and faces the primary coil and the device is located substantially on another side of the magnetic means and wherein the magnetic means improves electromagnetic coupling of the external primary charging coil and internal secondary coil.
A monitoring arrangement according to claim 26 wherein the magnetic means is a ferrite disk.
