Abstract: A connector and method is disclosed for connecting a thoracic catheter to a source of suction. The connector comprises a first tube approximately equal in inner diameter to the inner diameter of the main lumen of the thoracic catheter and a second tube connected to and in fluid communication with the first tube along a common longitudinal axis. The first and second tubes form a continuous non-constricted passage through the first and second tubes. In one embodiment, a connecting tube is placed over and in binding contact with the second tube at one end and in contact with the source of suction at the other end. In another embodiment, primarily for use with catheters with a funnel tip for connecting to the source of suction, the first and second tubes have inner diameters approximately equal to the inner diameter of the main lumen of the thoracic catheter.
