Real Time Monitoring of Hemodinamic Variables using Smart Stents (iSTENT) based on Capacitive and Bioimpedance Sensors

The coordinated proposal Real Time Monitoring of Hemodinamic Variables Using Smart Stents (iSTENT) Based on Capacitive and Bioimpedance Sensors aims to progress towards the design and manufacture of microsystems for the real-time monitoring of Intra Stent Restenosis (ISR) and Heart Failure (HF) by means of measuring relevant parameters for the diagnosis of cardiovascular diseases. In short, collaborating to improve the life quality of patients, thanks to the advancement in eHealth, increasing the effectiveness of biomedical monitoring systems.
The SubProject 1 (SP1) Integrated Microsystem based on bioimpedance measurements for the monitoring of arterial restenosis, focuses its work hypothesis on the implementation of electrical bioimpedance measurements to obtain the required useful information of the stent that allows to evaluate the degree of the coronary artery obstruction where it is implanted, as well as the hemodynamic variables involved in its state. The SubProject 2 (SP2) Integrated heterogeneous system for the monitoring of heart failure based on capacitive pressure sensors, proposes to use capacitive MEMS pressure sensors for the monitoring of blood pressure and HF by means of the left ventricle preload. Thus, SP1 pursues the realization of an iStent with the ability to monitor its internal obstruction (ISR) once implanted, avoiding the invasive and high risk procedure for the patient that involves performing a catheterization. Similarly, SP2 proposes the design, characterization and manufacture of an iStent for the monitoring of the HF, based on an heterogeneous integrated circuit for the pressure measurement in the distal pulmonary artery without having to use invasive diagnostic techniques. Besides, both proposals target the adquisition of additional measurements of other hemodynamic variables.
