The Australian Pacemaker: Telectronics (1965-1995)

In 1965, Australian medical device pioneer Noel Gray established Telectronics – Australia’s first manufacturing facility for producing pacemakers that were designed in-house.  Telectronics was an innovative developer, achieving some major successes in the early cardiac pacing field, for example, Telectronics’ leads allowed narrowing the pacing pulse to its current nominal of 0.5 milliseconds; encapsulating the pacemaker in titanium

DF-4 Connectors for Implantable Cardioverter Defibrillators Enter Use in the US

The DF-4 Connector was recently introduced by a joint group of CRM companies, physicians, and regulatory agencies as a way of easing the implant of ICDs by reducing defibrillation connections from three to one and by minimizing the number of set screws.  Prior to the development of the DF-4, traditional high-voltage connector systems required up to three connections.

Remon Medical’s Implantable Pulmonary Pressure Sensor (1997-2007)

Remon Medical Technologies, Ltd. was founded in 1997 in Caesarea, Israel to develop implantable, wireless pressure sensors. Remon developed an implantable hemodynamic monitor, which allowed on-demand, non-invasive, leadless self-monitoring of pulmonary artery pressure by the patient at home. ImPressure devices were placed in the pulmonary artery, and transmitted pressure readings to a hand-held monitor.  It was hoped that the

Purdue University’s Concept for Music-Powered Implantable Devices

  A group of researchers at Purdue University led by Prof. Babak Ziaie developed a vibrating cantilever that is excited by an external bass source from 200-500 Hz. The excitation causes the cantilever to vibrate, generating electricity and storing a charge in a capacitor. Although playing tones within a certain frequency range would be ideal, the

“Data Block” Percutaneous Implantable Electrical Connector

The development of medical devices, drugs, and treatments depends on accurately retrieving clinical data from implanted animals. Implantable data collecting and sensing devices provide one way to retrieve these data. These device often include sensors or electrodes which must be implanted within the subject in order to provide clinicians with access to the sensed information.
