1. An elongate medical device comprising:
- an elongate tubular body defining a longitudinal axis with a body proximal portion and a body distal portion;
an electrode comprising an electrically-conductive ink extending circumferentially about an exterior portion of the elongate tubular body, wherein the electrode is located on the body distal portion;
a trace comprising electrically-conductive ink electrically coupled with the electrode, the trace extending longitudinally from the electrode, wherein a first portion of the trace is on the body distal portion and a second portion of the trace is on the body proximal portion; and
a force sensor comprising a semiconductive layer radially disposed between a first electrically-conductive layer and a second electrically-conductive layer, the force sensor extending along a portion of the elongate tubular body,wherein the body proximal portion comprises a first material with a first melting temperature and the body distal portion comprises a second material with a second melting temperature where the second melting temperature is higher than the first melting temperature.

Abstract
An elongate medical device may comprise an elongate tubular body, an electrode, and a trace. The elongate tubular body may comprise a distal end portion and a proximal end portion, the body defining a longitudinal axis. The electrode may comprise electrically-conductive ink extending circumferentially about a portion of the distal end portion. The trace may comprise electrically-conductive ink, electrically coupled with the electrode, extending proximally from the electrode.
