Abstract
An intravascular device, such as a stylet or catheter, having a flexible, atraumatic tip is disclosed. The intravascular device includes an elongate member having a proximal end, a distal end, and an inner lumen extending between the proximal end and the distal end; a ring electrode disposed at the distal end of the elongate member; an ultrasound sensor disposed at a distal end of the ring electrode; and a first electrical conductor configured to convey an electrocardiogram signal from the ring electrode to a processor. The first electrical conductor may comprise a tapered distal segment or a braided segment.
