Patent Issued for Finding elongation of expandable distal end of catheter (USPTO 12156977).

The patent issued for finding the elongation of the expandable distal end of a catheter involves a system with an expandable distal-end assembly, proximal and distal position sensors, and a processor. The system estimates the position and longitudinal direction of the sensors to calculate the elongation of the assembly. The patent aims to improve medical systems by accurately measuring and indicating the degree of elongation of expandable catheter assemblies. [Extracted from the article]
