Estimating the term…
A guide wire assembly comprises a tubular body having a distal end and an proximal end. At least a portion of the body comprises a single continuous helical spring to which one or more tubular electrodes are secured. The electrodes are insulated from the spring by means of an insulator. The electrodes can take a variety of forms, including conductive ribbons, longitudinally split conductive tubes, tubular sections, etc. The guide wire assembly may further include a variety of sensors, such as velocity sensors or temperature sensors. In order to allow flowable material to be passed to the distal end of the guide wire, the guide wire can include a catheter tube passable over the tubular body of the guide wire.
A guide wire assembly comprising a tubular body having a single continuous helical spring forming at least a portion thereof, an insulative sleeve covering at least a portion of the helical spring, and a tubular electrode mounted on the body over the insulative sleeve with the sleeve insulating the electrode from the spring.
