Date Mar. 5, 1998A guidewire for use in endoscopic retrograde cholangio pancreatography (ERCP) includes a proximal section defined by a fiber rod, a tube, and a connection mechanism for attaching the tube and fiber rod together in a collinear relationship. The guidewire also includes a flexible distal section which is attached to the distal end of the tube. The distal section is comprised of a superelastic core having a radiopaque marker disposed about its distal end, and at least a portion of the distal section is enveloped by an insulative sleeve. The superelastic core may be tapered, and the fiber rod may comprise a multiplicity of fibers encapsulated in a resin. |
