Fiber optic enabled stylet

Abstract

A catheter placement system that includes a catheter placement device having elongate body configured for insertion into a catheter lumen, where the elongate body includes a body lumen. A compartment at a proximal end of the body is in fluid communication with the body lumen. A saline solution disposed within the compartment and the body lumen defines an electrical path along the elongate body and an electrode at a distal end of the elongate body. A stylet extends along the elongate body, where the stylet includes a multi-core optical fiber extending along the stylet, and where the multi-core optical fiber includes a number of fiber Bragg gratings disposed along the optical fiber to enable shape sensing of the optical fiber. A system module optically and electrically coupled with the catheter placement device displays a shape of the elongate body and ECG waveform.
