“…This technology results in small sizes. However, it has a disadvantage of shorter operation distance of around 0.5 to 20 cm [121]. CardioMEMS has a passive telemetry based implanted wireless blood pressure sensor system working over a distance of 20 cm and size of 5x30 mm 2 [122].…”

“…Contrary to the foregoing, if the elastic module of the outer ring is much lower than the other two, the factor tends to be 0, a condition that presents sensitivity problems in the measurement system because variations in the fluid pressure in the inner cavity of the ring would be very small with respect to those from the arterial wall. Therefore, it is recommended to use scale values in the range of 0.1 − 0.3 [2].…”

“…Within these systems, one of the greatest challenges is in-situ blood pressure measurement for the corresponding monitoring and control. The most common technique used is through an invasive catheter that comes in contact with the blood flow as it is inserted into the artery [2]. However, this technique requires a surgical procedure and promotes blood pressure increase, bleeding, coagulation problems, and sensory reduction over time [1].…”

Abstract-This paper explains the use of a model to design an implanted blood pressure monitoring system through simulations in COMSOL Multiphysics® by using FSI Module. These measurement systems need to have a minimal blood contact to reduce the thrombus formation, bleeding, and avoid vessel occlusion, which are associated with the conventional catheter-tipbased technique. The model employs an elastic sensing cuff, wrapped around the artery section, made of silicone filled with biocompatible fluid with an immersed MEMS pressure sensor. From this mechanical interaction, the measured waveform represents a down-scaled version of the blood pressure waveform, where the simulation scale factor was 0.2859. From the analytical study, the scale factor was 0.2921, which results in an error of 2.1%. With this factor it is possible to adjust the measurement system for different medical applications.Keywords-Blood pressure, MEMS (Microelectromechanical System), measurement cuff, blood vessel.

“…Research on implantable pressure sensors is very active and has been supported and justified by the need of continuous pressure monitoring for patients with congestive heart failure, as an early diagnostic mechanism for some risk patients and for post-EVAR surveillance [24][25].…”

“…Implantable pressure sensors are typically categorized into extra-arterial blood pressure devices and intra-arterial blood pressure devices [25]. The firsts are placed around the blood vessel and perform an indirect pressure measurement through the wall or through the expansion and contraction of the artery.…”

Abdominal aortic aneurysms (AAA or triple A's) are indolent and deadly diseases. Their treatment options involve either an invasive procedure or a minimally invasive one. When the minimally invasive procedure, endovascular aneurysm repair (EVAR), was introduced, it revolutionized the treatment of AAA's due to advantages such as shortened hospital stays and reduced costs. As EVAR requires periodic imaging exams, questions are nowadays being raised regarding the procedure's long-term cost-benefit relation. In order to reduce followup costs, new technological solutions are being pursued, namely EVAR stentgrafts with sensing capabilities. In this chapter, the suitability of aneurysm sac pressure measurement for EVAR surveillance is evaluated using an AAA computer model. In addition the design drivers underlying EVAR stent-grafts are reviewed and the development of a new flexible pressure sensor integrated into a stent-graft is described.
