Transducers, Pressure, Vascular Aneurysm
Definition : Transducers designed to measure the pressure inside a vascular 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. These devices are typically implantable transducers that convert pressure to radiofrequency or ultrasound signals; the transducers work with an external console that reads the pressure from the transducer and displays the results. 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.
