Transducers, Pressure, Vascular Aneurysm, Ultrasound

Definition : Transducers designed to convert pressure to ultrasound energy to measure the pressure in an aneurysm sac that is excluded from the blood circulation (usually in an area of thrombus) by a stent-graft implanted to repair the vascular aneurysm. The transducer works with an external unit including a handheld probe that makes contact with the skin to read the pressure from the transducer signal. These transducers are typically a hermetically sealed device that is fixed to the outside of the stent-graft; the transducer includes a piezoelectric membrane that charges a capacitor when energized by ultrasound waves from a handheld probe; once charged the transducer sends back an ultrasound signal to the external unit that varies according to the value of the pressure. Ultrasonic vascular aneurysm pressure measuring transducers, in combination with a matching external unit, are used during endovascular procedures intended to repair vascular aneurysms (typically abdominal aortic aneurysms); comparing the value of the pressure in the aneurysm sac before and after the exclusion of the sac from the blood circulation during the aneurysm repair procedure facilitates the detection of internal leaks.

In 1969, fascinated by the possibility of bringing pioneering medical devices and treatments to patients across the world, John Abele joined Medi-Tech, a company that was developing alternatives to traditional surgery. Pete Nicholas was looking for an investment, and when he met John, the pieces came together.
