Abstract:Transcatheter aortic valve implantation has shown superior clinical outcomes compared to open aortic valve replacement surgery. The loss of the natural sense of touch, inherited from its minimally invasive nature, could lead to misplacement of the valve in the aortic annulus. In this study, a cylindrical optical fiber sensor is proposed to be integrated with valve delivery catheters. The proposed sensor works based on intensity modulation principle and is capable of measuring and localizing lateral force. The … Show more
“…Although guidance is provided using X-rays during the procedure, it is of interest to understand the forces exerted by the catheter head on the blood vessel wall to avoid damaging it. In this way, the paper by Bandari et al [ 6 ] proposes a force sensor based on the use of an optical fibre array. This is placed on the catheter head, and the deformation of the optical fibre array caused by the contact forces is used for estimating the interaction forces.…”
There are many definitions for the concept of a robot, perhaps too many; it has even been said that we do not know how to define them, but when we see a robot, we identify it [...]

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
