    en.wikipedia.org/wiki/Telectronics

    In 1971 Telectronics commenced testing samples of a new type of energy source for pacemakers, the lithium cell (lithium battery) being developed by Wilson Greatbatch and in 1972 commenced development of a range of integrated circuits capable of operation from the 2.8 volts of the cell while providing a stimulating pulse of 4.5 volts.

  4. MRI RF shielding - Wikipedia

    en.wikipedia.org/wiki/MRI_RF_shielding

    MRI RF shielding. RF shielding for MRI rooms is necessary to prevent noise of radio frequency from entering into the MRI scanner and distorting the image. The three main types of shielding used for MRIs are copper, steel, and aluminum.

  5. Pacemaker - Wikipedia

    en.wikipedia.org/wiki/Pacemaker

    A pacemaker, also known as an artificial cardiac pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart. Each pulse causes the targeted chamber(s) to contract and pump blood, [ 3 ] thus regulating the function of the electrical conduction system of the heart .

    The new company focused on cardiac rhythm management (pacemakers and implantable defibrillators) and cardiac and vascular intervention products via coronary and peripheral stents, guidewires and balloon dilatation catheters. Less invasive heart surgery was another small business unit of Guidant.

  7. Cardiac pacemaker - Wikipedia

    en.wikipedia.org/wiki/Cardiac_pacemaker

    An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...

  8. Biological pacemaker - Wikipedia

    en.wikipedia.org/wiki/Biological_pacemaker

    The biological pacemaker is intended as an alternative to the artificial cardiac pacemaker that has been in human use since the late 1950s. Despite their success, several limitations and problems with artificial pacemakers have emerged during the past decades such as electrode fracture or damage to insulation , infection , re-operations for ...

    en.wikipedia.org/wiki/Ventricular_assist_device

    The Wireless power transfer technology based on technique called Coplanar Energy Transfer (CET) which is capable of transferring energy from an external transmitting coil to a small receiving coil that is implanted in the human body. In the early postoperative phase, CET operation was accomplished as expected in both patients, which powered the ...
