摘要： The catheter includes a multi-lumen tube having an outflow portion and an accessory portion. The accessory portion is integrally formed within an interior volume of the outflow portion. The accessory portion has a cross-section smaller than the outflow portion. The outflow portion is offset from the accessory portion such that they are integrally joined. The space between these portions defines a fluid return passageway and the space within the accessory portion defines an accessory passageway. A flexible outer sleeve cooperates with the multi-lumen tube to form a fluid inlet passageway. During operation, an inlet flow of warming fluid flows through the fluid inlet passageway formed between the outer sleeve and the multi-lumen tube. The flow continues around a distal end of the outflow portion of the multi-lumen tube, thus becoming an outlet flow of the warming fluid which is directed through the fluid return passageway.

摘要： The quick disconnect assembly includes a reusable assembly including a distal end having a male lip thereon; and, a disposable assembly having quick disconnect capabilities when utilized with the reusable assembly. The disposable assembly includes a stem section; a finger lock element; and, a detachable handle assembly. The finger lock element includes a distal finger lock element section having a threaded inner surface for engagement with a threaded outer surface of the stem section; and, a plurality of radially spaced fingers extending proximally from the distal finger lock element section. Each finger has a) a ramped surface for operatively engaging an associated ramp section on the stem section during use; and, b) a female lip at a proximal end thereof. The detachable handle assembly includes a proximal handle section having a distal end having an inner surface that is operatively engaged with an outer surface of the finger lock element so as to resist relative rotation and axial motion therebetween. A distal handle section of the detachable handle assembly includes a distal handle section having an inner surface that is operatively engaged with another outer surface of the stem section so as to resist relative rotation and axial motion therebetween. A breakaway collar of the detachable handle assembly is positioned between the proximal handle section and the distal handle section. When the disposable assembly is attached, the breakaway collar is an integral unit which prevents relative rotation between the proximal handle section and the distal handle section, the female lip engaging the male lip at a distal end of the reusable assembly, thereby securing the reusable assembly to the disposable assembly. The quick disconnect assembly may be used to provide only a mechanical connection or it may be provided with components for providing fluid transfer. In another embodiment, instead of only providing for single use, multiple use of a detachable assembly is provided by eliminating the breakaway collar and utilizing spring biasing means.
