Abstract
A pericardial implantable cardioverter defibrillator (ICD) may be delivered to the heart through the chest wall using an ultrasound image guided catheter. The ICD may comprise a patch and wire leads which may be secured by a clam shell-like pad at a distal end and comprise a pig-tail shaped securing tail at the other end so that the ICD is firmly attached to the pericardium of a human heart. The ICD may be attached where most needed and serve as either a pacemaker or a defibrillator. In one embodiment, the ICD may emit radio frequency warning signals of heart failure sensed when pacemaker or defibrillator usage is rendered necessary.
Claims4
A heart defibrillator for attachment to the pericardium of the heart at a least one location on the pericardium proximate a chamber of the heart requiring monitoring and periodic application of electrical pulses, the heart defibrillator comprising in combination the following components:
- at least one electrode comprising a wire coil or a circular, rectangular or square patch with an embedded wire coil, the electrode covering, a portion of the pericardium proximate the chamber requiring periodic pulsing,
- a controller for receiving electrical signals from the heart via an embedded wire representing beating of the heart and for transmitting electrical signals to the embedded wire to stimulate a regular heart beat when needed,
- the controller comprising a memory for storing a special purpose computer program for determining when electrical stimulation is required and at what electrical voltage level and the memory for further storing a record of the received electrical signals from the embedded wire over time and further data over time indicating each time of transmission of an electrical stimulating pulse via the embedded wire,
- the defibrillator further comprising a radio frequency transmitter for broadcasting when a battery for powering the defibrillator requires replacement or when electrical signals received from the heart indicate a life-threatening emergency.
