“…45 In the following years, similar sensors with vibrating membranes located at the tip 39,97,98 or at the side of a catheter have been proposed. 123,124 Side membranes should contribute to reduce pressure artifacts due to tip collisions with the blood vessels or the ventricular walls (the so-called wall or piston effect) [124][125][126] and to avoid clot formation occurring for long periods of monitoring. 123, 124 An earlier application of a pressure sensor incorporating a side membrane was proposed by Matsumoto et al 124 ( Fig.…”

Abstract. As optical fibers revolutionize the way data is carried in telecommunications, the same is happening in the world of sensing. Fiber-optic sensors (FOS) rely on the principle of changing the properties of light that propagate in the fiber due to the effect of a specific physical or chemical parameter. We demonstrate the potentialities of this sensing concept to assess pressure in biomedical and biomechanical applications. FOSs are introduced after an overview of conventional sensors that are being used in the field. Pointing out their limitations, particularly as minimally invasive sensors, is also the starting point to argue FOSs are an alternative or a substitution technology. Even so, this technology will be more or less effective depending on the efforts to present more affordable turnkey solutions and peer-reviewed papers reporting in vivo experiments and clinical trials. © The Authors.

“…Meanwhile, a good example of novel applications of light intensity-modulated sensors supported by reflective membranes is the radiofrequency (RF) ablation catheter with force feedback, presented by Polygerinos et al [91,92], from the Department of Mechanical Engineering of King's College of London. Three plastic optical fibers were aligned inside a plastic catheter in a circular pattern to provide a three axes force sensing system (Fig.…”

Fiber optic intensity-modulated sensors: a review in biomechanics

et al. 2012

Fiber optic sensors have a set of properties that make them very attractive in biomechanics. However, they remain unknown to many who work in the field. Some possible causes are scarce information, few research groups using them in a routine basis, and even fewer companies offering turnkey and affordable solutions. Nevertheless, as optical fibers revolutionize the way of carrying data in telecommunications, a similar trend is detectable in the world of sensing. The present review aims to describe the most relevant contributions of fiber sensing in biomechanics since their introduction, from 1960s to the present, focusing on intensity-based configurations. An effort has been made to identify key researchers, research and development (R&D) groups and main applications.

“…PCI is carried out using a catheter. During a cardiac catheterization procedure, the physicianattempts to reach certain locations through the blood vessels andperform an examination or treatment on the tissues of the heart [1]. The catheter exertsvarious forces onto the blood vessel walls from its tip and sides asit moves inside the patient's vasculature system.…”

Abstract:Avoiding the electromagnetic interference is one of the most difficult technical challenge during catheterization. The use of an optical fiber force sensor in the catheter can be an alternative. Herein, two flexure structures were designed for catheter tip and simulated using ANSYS to verify their sensitivity and durability. Fiber Bragg Grating sensors were configured to measure the tri-axial force exerted on the catheter tip. Calibrated result shows that an optical fiber force sensor can measure an axial force of up to 50 gF with an accuracy of 1 gF. Our calibration results demonstrate reliable measurement with high accuracy with repeatability.
