ABSTRACT:
An exchange guidewire for positioning and exchanging medical catheters within a bodily passage during a medical procedure which uses an endoscope. The guidewire includes a wire of a length sufficient for exchange of the catheters through the endoscope, a radiopaque flexible coil fixed to the distal end of the wire, and a pattern of stripes endoscopically discernable along the guidewire. Optionally, a shrink-wrap, low-friction sleeve jackets the guidewire, the pattern of indicia being endoscopically discernable along the length of the jacketed guidewire. The position of the exchange guidewire indicia relative to the endoscope optical lens may be monitored by viewing the stripes endoscopically. A method of positioning and exchanging medical catheters within a bodily passage during a medical procedure which uses an endoscope is also disclosed.
