Abstract:
An improved non-balloon dual mode catheter capable of simultaneous insertion over at least one long guide wire and at least one short guide wire, the long guide wire longer than the short guide wire, the catheter comprising:a substantially tubular member having a proximal control end and a distal functional end; a long guide wire lumen disposed within the tubular member, the long guide wire lumen being substantially coextensive with the tubular member and further comprising a first exit aperture located proximate the proximal control end and a second exit aperture located proximate the distal functional end; the long guide wire lumen adapted to receive a long guide wire therethrough and further adapted to receive fluids therethrough; the long guide wire being moveable with respect to the long guide wire lumen during use; a short guide wire lumen disposed within the tubular member, the short guide wire lumen adapted to receive a short guide wire therethrough, the short guide wire lumen further comprising an exit aperture disposed proximate the distal functional end; and a short guide wire aperture, adapted to receive a short guide wire, the short guide wire aperture disposed through an outer surface of the tubular member and located intermediate the proximal control end and the distal functional end, the short guide wire aperture in communication with the short guide wire lumen whereby the short guide wire lumen is in communication with the outer surface of the tubular member through the short guide wire aperture.
