    摘要： A connector has a hollow body having a first open end spaced apart from a second open end with a lumen extending between the first and second open ends. At least one channel extends through a sidewall of the body and is recessed from a terminal surface of the first open end. The first open end is sized to be received within an open end of a first tubing. When the first open end is partially inserted into the open end of the first tubing, the at least one channel and a terminal surface of the open end of the first tubing define an opening positioned so that fluid passes through the opening into or out of the lumen. When the first open end is fully inserted into the first tube, the at least one channel is covered by an inner surface of the first tubing to cover the opening.

    摘要： A dual lumen coaxial cannula assembly including a first infusion tube having a proximal end, a distal end, and a sidewall extending circumferentially therebetween, as well as a second drainage tube co-axially aligned with the first infusion tube, the second drainage tube having a proximal end, a distal end, and a sidewall extending circumferentially therebetween. The assembly also includes a connector assembly, which has an inlet portion through which a portion of the first infusion tube is configured to extend and an outlet portion through which a portion of the second drainage tube is configured to extend. The connector assembly is configured to enable selective axial displacement of the first infusion tube through the second drainage tube.

    摘要： A veno-arterial extracorporeal membrane oxygenation system includes a dual lumen drainage cannula configured for withdrawing blood from a patient's vasculature in a manner that provides a perfusion of oxygenated blood with reduced carbon dioxide content while unloading the left ventricle, with two points of access to the patient's vasculature. The dual lumen drainage cannula has a first drainage tube and a second drainage tube co-axially aligned with the first drainage tube. The first and second drainage tubes are fluidly coupled to a connector. A blood pump having a pump inlet is configured for fluidly connecting with the connector, while an oxygenator having an oxygenator inlet is configured for fluidly connecting with a pump outlet. An infusion cannula is configured for fluidly connecting with an oxygenator outlet for infusing oxygenated blood into a patient's bloodstream.
