Abstract: A connector for use in flushing or drawing fluid through an inner lumen of a tubular member has a body with a proximal end, a distal end, and a flushing lumen extending therethrough. The body has a distal portion wherein the flushing lumen increases in size from a first proximal cross-sectional area to a second larger distal cross-sectional area so that an annular surface within the distal portion presses against an end of the tubular member when the end of the tubular member is inserted into the distal end of the body. A temporary fluid seal is created between the body and the tubular member when the tubular member is pressed against the annular surface. In one preferred embodiment, a flange is disposed within the connector, the flange being designed so that a portion of the flange extends into the inner lumen of the tubular member when the tubular member is pressed against the annular surface, thereby providing a path for leading a guide wire into the inner lumen.

Abstract: A method and apparatus are provided for withdrawing a catheter proximally from a guide catheter lumen while supporting a guide wire in a longitudinal and lateral direction proximal to the guide catheter lumen. The guide catheter lumen has a guide catheter lumen, a proximal end and a distal end. A catheter extends through the guide catheter lumen and has a guide wire lumen at a distal portion thereof having a proximal end and a distal end. A length of the guide wire lumen is shorter than a length of the catheter. A guide wire extends through the guide wire lumen and the guide catheter lumen. A sleeve is provided over a segment of the guide wire extending proximally from the guide catheter lumen. The sleeve maintains that segment of the guide wire in close lateral proximity to the catheter as the catheter is withdrawn proximally from the guide catheter lumen and the guide wire is restrained from such proximal movement.
