Abstract
An electrophysiology catheter () includes a catheter distal portion () on which a force sensor () is arranged. The force sensor () includes an elastic tube () and strain gauges (). The elastic tube () has a hollow portion in its wall, and the strain gauges () are disposed external to the hollow portion. Compared to the design with the strain gauges () overlapping the hollow portion, arranging them over solid portions of the elastic tube () allows the strain gauges () to collect more accurate electrical signals while suffering from less interference. This can result in a significant improvement in contact force measurement accuracy of the catheter distal portion ().
