Lidwill’s knowledge and expertise extended not only to his invention of the cardiac pacemaker but to the design and manufacture in 1910 of his mechanical-anaesthesia apparatus, the “Lidwill Inter-tracheal Anaesthetic Machine”, which remained in use in operating theatres in hospitals throughout Australia for more than 30 years.
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 .
After successfully testing the hand-made device in the laboratory, Bakken returned to create a refined model for patients. However, much to his astonishment, when he came in the next day, he found the pacemaker already in use on a patient. (The Food and Drug Administration did not start regulating medical devices until 1976.) [4]
