Abstract:
An apparatus and method for introducing a secondary wire guide into a patient over an indwelling primary wire guide. The apparatus includes a catheter comprising an elongated shaft having proximal and distal end portions and a main lumen extending through a substantial portion thereof. The distal end portion of the catheter further includes a relatively short secondary lumen defined by an inner partition that subdivides the interior volume of the shaft so as to separate the secondary lumen from the main lumen. A pair of ports are disposed in the distal end of the catheter, one port being in communication with the main lumen and the other being in communication with the secondary lumen. A proximal opening is disposed near the proximal end of the catheter and is in communication with the main lumen. A pair of spaced apart side ports extend through the side wall of the catheter shaft at a location intermediate the distal and proximal ends of the catheter, one port being in communication with the main lumen and the other being in communication with the secondary lumen.
