Serge Barold Florida Heart Rhythm Institute, Tampa, Florida, USA Wilson Greatbatch was born September 6, 1919, in Buffalo, New York State as the only child of Warren Greatbatch a construction contractor and Charlotte Greatbatch who worked as a secretary. He died on September 27, 2011 at the age of 92. Greatbatch trained as an electrical engineer at Cor- nell University and the University of Buffalo where he then taught engineering between 1952 and 1957. While building an oscillator to record heart sounds, Greatbatch made a fortuitous discovery. He grabbed the wrong resistor from a box and plugged it into the circuit he was making. The unit gave off a startling- ly familiar, uneven electrical pulse. The circuit pulsed for 1.8 ms, stopped for 1 s and the sequence was then Figure 1. The “bow tie” trio.

  • Earl Bakken's Little White Box: the Complex Meanings of the First
    David Rhees, Kirk Jeffrey* Earl Bakken’s Little White Box: The Complex Meanings of the First Transistorized Pacemaker† On a brilliant August morning in 1994, a large crowd of officers, employees, and stockholders of the medical device firm Medtronic, Inc., gathered outside the company headquarters in a northern suburb of Minneapolis, Minnesota, U.S.A., for an important ceremony. The occasion was the retirement from the board of directors of Earl E. Bakken, who in 1949 had co- founded the company and had helped make it into the world’s leading manufacturer of cardiac pacemakers.1 There were many speeches that morning, but the highlight of the ceremony was the unveiling of a full-sized statue of Bakken that stood facing the main door of the company headquarters building. Partially encircling the statue was a low stone wall engraved with the mission statement that Bakken had written in the early 1960s, which was still in force more than three decades later. While the words spelled out the values for which the company had become famous in the medical community, the visual symbol of Medtronic’s corporate culture was held in the statue’s outstretched right hand. There, forged in bronze, was a replica of the device that Bakken had invented during the winter of 1957–58—the world’s first wearable transistorized cardiac pacemaker.2 The bronze replica in the statue’s hand represents the crude prototype that Bakken made at the request of a renowned heart surgeon at the University of Minnesota. This prototype, housed in aluminum and containing only two transistors, had been intended for tests with dogs but was used on human patients within days of its invention.

  • Medical Mechanic
    Medical Mechanic Article written by Alice M. Vollmar and published in The World & I, December, 2003 Earl Bakken made a better pacemaker, founded and led a major medical technology company and is leading the merger of high-tech and "high-touch" medicine in Hawaii. Fascinated from childhood with all things related to electricity, Earl E. Bakken, along with his brother-in-law, started a medical equipment repair company named Medtronic, Inc. in a garage in 1949. Under Bakken’s leadership, that company grew into a leading medical technology company based on his belief that "failure is closer to success than inaction." This philosophy, which underscores Bakken’s life, took root in his Minnesota childhood home where his mother supported her precocious son’s tinkering. Born in 1924, to Florence and Osval Bakken in Columbia Heights, Minnesota, in the northeastern corner of Minneapolis, Bakken recalls his mathematician grandfather Lars Bakken always sketching plans for mechanical devices. His own father, an avid reader, constantly worked crossword puzzles. His mathematically inclined mother, with a business training background, gave young Earl remarkable freedom to fool around with electrical gadgets, wiring, and batteries at home. His curiosity about the electrical wiring in his home led his electrician uncle to predict sternly that young Earl would electrocute himself someday. A curious childhood As a child, Bakken had the household to himself. (His only sibling is a sister 18 years younger.) In his autobiography, One Man’s Full Life, published in 1999, Bakken speculated that his mother may have been so tolerant because she shared his enthusiasms, including the Fourth of July firecrackers that Bakken wired to be set off electrically from his perch in the attic window.

  • Implantable Pacemaker (Medical Device: Therapeutic)
    MEDICAL INNOVATION: IMPLANTABLE PACEMAKER (MEDICAL DEVICE: THERAPEUTIC) Physician: Drs. C. Walton Lillehei, William Chardack and Andrew Gage and electrical engineer Wilson Greatbatch Industry: Medtronic Situation A leading cause of death Heart rhythm disorders, or arrhythmias, occur when the heart beats too quickly, too slowly, or in a chaotic manner. These disorders, which affect two million Americans each year, are caused by electrical problems in the heart, and result in fatigue, fainting, dizziness and even sudden death. In addition, five million Americans suffer from congestive heart failure, which causes the main chambers of the heart to pump inefficiently and can cause the heart to beat in an unsynchronized manner, also referred to as ventricular fibrillation. The vast majority of the 335,000 sudden deaths that occur in the United States every year are believed to be caused by ventricular fibrillation. Heart failure is the main cause of hospital stays in the U.S., and its total cost to the economy is over $30 billion annually. Physician-Industry Collaboration Building on a pioneering design In the 1950’s, external heart pacemakers existed to help regulate heart rhythm, however they were bulky, relied on external electrodes, and had to be plugged into a wall outlet, and could fail during a power blackout. One of the co-founders of medical device manufacturer Medtronic, engineer Earl Bakken, collaborated with a pioneer in open heart surgery at the University of Minnesota Medical School, Dr. C. Walton Lillehei, to develop a wearable, external, battery- powered pacemaker not much larger than a paperback book. This signaled the beginning of a new era in the therapeutic application of electrical stimulation for patients around the world.

  • Lithium Batteries for the Silicon Body
    THE digital HUBER MILLS power report March 2002/Vol. 3 Issue 3 Powering the 21st Century Published by Gilder Publishing, LLC Lithium Batteries for the Silicon Body Greatbatch has all the bona fides miniature brushless DC motor, built by Danaher’s Kollmorgen (DHR) (Digital Movers, February 2002), runs the 10,000 rpm of a firmly established leader in A pump in the AbioCor artificial heart. An ultra-high-energy-density digital power lithium battery, implanted inside the heart itself, supplies about 30 minutes of primary power to the motor. That battery is recharged, in turn, via a mag- netic charging system (no wires through the wall of the chest) that links to a larger (VCR-sized) lithium battery pack that the patient wears on a belt. Both batteries are manufactured by Wilson Greatbatch Technologies (GB). If the battery’s going into your body, it almost certainly has lithium inside it, and Wilson Greatbatch’s name on the box. Artificial hearts remain rare, but there are over 500,000 lithium-powered devices implanted in humans every year. When it comes to ultra-high-power density, and equally high reliabil- ity in a stable, safe, temperature-tolerant battery, nothing else comes close. Greatbatch’s core products fall into five broad categories, defined by their chemistry: Lithium-iodine cells used for pacemakers, lithium-silver vanadium-oxide cells used primarily for defibrillators, lithium- thionyl-chloride cells used in drug infusion devices and neurostimulators, lithium-carbon-monofluoride cells that are an alternative to lithium-vanadium-oxide, and lithium-ion rechargeables. Greatbatch sells standardized off-the-shelf batteries; it also customizes systems for the OEMs in the medical implant business.
