Wireless Blood Pressure Monitoring with a Novel Implantable Device: Long-Term In Vivo Results

Abstract

The pilot study proved the technical feasibility of wireless BP measurement in the FA via a novel miniature sensor device.

A novel wireless implant for central venous pressure measurement: First animal experience

“…The mean pressures may facilitate the assessment of clinically relevant changes associated with hemodynamic congestion. 29 …”

Miniature implantable telemetry system for pressure-volume cardiac monitoring

“…In [89,192], a fully implantable wireless pressure monitoring system was developed for hypertension patients. Here, both a custom pressure sensor and telemetry system were developed, however, it was designed to monitor femoral pressures and not the higher LV pressure.…”

“…A low-power telemetry system [4] is capable of being implanted for longer periods of time while operating off of smaller capacity batteries. Active measurement cages have been used to provide wireless power to the implants enabling long-term data collection without the need for batteries [21,88] Current state-of-the-art wireless cardiac telemetry systems typically employ blood pressure (aortic), ECG, and temperature sensors [21,22,89]. Although small and advanced, these systems currently do not measure left ventricular blood volume, thus cannot be used to measure PV loops.…”

Telemedicine in Cardiology. Part 2. Personalised Telemonitoring of Blood Pressure and Pulmonary Circulatory Dynamics in Outpatient Settings

“…Единственный прямой способ измерения АД -инвазивный, метод предполагает введение датчика непосредственно в просвет артерии. Проводятся исследования, направленные на разработку имплантируемых аппаратов для прямого измерения АД с функцией дистанционной передачи данных [7].…”
