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. In another embodiment, a longitudinal groove extends the length of the connector to provide for the lateral removal of the connector from a guide wire.
