Catheter assembly with flexible shaft and multi-core fiber
A recently granted patent (Publication Number: US11998310B2) discloses a catheter assembly featuring a catheter tip assembly with a flexing structure designed to bend in response to external forces. The assembly includes an electrode with a cavity and a multi-core fiber containing fiber Bragg gratings for sensing the shape of the flexing structure. Additionally, the multi-core fiber can sense forces applied to the flexing structure, with different cores dedicated to shape and force sensing using distinct optical sensing methods.
Furthermore, the catheter assembly described in the patent incorporates various configurations for the multi-core fiber, including cores that can be bent or axially compressed. The flexing structure of the catheter tip assembly may include a deformation mechanism, and the distal end of the cores within the fiber can be amalgamated or crushed. The patent outlines different embodiments of the assembly, each emphasizing the ability to accurately sense both the shape and forces acting on the flexing structure, enhancing the functionality and precision of catheter-based procedures.
