초록 ▼

A multilumen catheter having a plurality of flexible, elongated catheter tubes concentrically and coaxially disposed, each catheter tube defining a separate lumen, each catheter tube having a distal end which extends outwardly from the distal end of the next surrounding catheter tube, and each catheter tube having a proximal end which is secured and encapsulated by a manifold which facilitates fluid communication between each of the separate lumens and fluid transfer devices or pressure monitoring devices via separate extension tubing.

대표청구항 ▼

A triple lumen venous catheter comprising: an inner venous catheter tube defining a first lumen having a proximal end, and a distal end with the inner catheter tube having a first opening to the first lumen at the proximal end and a second opening to the first lumen at the distal end; a middle venous catheter tube defining a second lumen and having a proximal end, a distal end and a cross-section which is greater than the cross-section of the inner tube, the middle tube being disposed concentrically and coaxially with the inner tube, and the distal end of the inner tube extending longitudinally outward from the distal end of the middle tube with the middle catheter tube having a first opening to the second lumen at the proximal end and a second opening to the lumen at the distal end; an outer venous catheter tube defining a third lumen and having a proximal end, a distal end and a cross-section which is greater than the cross-section of the middle tube, the outer tube being disposed concentrically and coaxially with the middle tube and the inner tube, and the distal end of the middle tube extending longitudinally outward from the distal end of the outer tube; the outer tube having an outer diameter corresponding to the inner diameter of a patient\s vein in which the outer catheter tube is to be inserted and the outer catheter tube having a first opening to the third lumen at the proximal end and a second opening to the third lumen at the distal end; a manifold securing and encapsulating each of the proximal ends of the inner, middle and outer venous catheter tubes to provide separate and noncommunicating passages to each of the inner, middle and outer tubes; and a plurality of extension tubes coupled to the manifold, each separately coupled to a respective one of the lumens.
