    摘要： A co-axial catheter assembly including a first lumen having a first distal end and a first proximal end, and a second lumen having a second distal end and a second proximal end. The second lumen extends co-axially with the first lumen, wherein the second lumen is at least partially disposed within the first lumen and the second distal end extends distally of the first distal end. A catheter hub provides for fluid connections of the inner and outer lumens with respective extension tubes, and includes spacers that maintain the proximal end of the inner lumen concentrically within the proximal end of the outer lumen and the distal end of the inner lumen concentrically within the distal end of the outer lumen, respectively. Methods of manufacturing and of inserting the catheter are also disclosed.

    摘要： A method is provided for inserting a multiple catheter assembly into an area of a body to be catheterized through a single incision. Two independent catheters which are independently movable with respect to each other, or unattached to each other, along their entire length are inserted into the single incision. In use, the first catheter withdraws fluid from the area and the second catheter delivers fluid to the area. As part of the insertion method, the longitudinal distance between proximal portions of the two catheters are adjusted to provide a predetermined longitudinal distance between distal portions of the two catheters within the area.

    摘要： A double-lumen catheter is made of two generally coaxial tubes. The tubes are joined, at their distal ends, by a sleeve inserted between the tubes, the sleeve being bonded to both tubes. The inner and outer tubes are connected, respectively, at their proximal ends, to first and second hubs. The hubs are bonded together. The distal ends of the tubes may be formed into a tapered tip, preferably having a rounded edge. The proximal ends of the tubes can be connected to external fluid devices. The invention also includes a method of making the catheter. According to this method, inner and outer tubes are separately formed, and the proximal end of each tube is connected to a hub. Then, the inner tube is threaded into the outer tube, until the distal ends of the tubes are near each other. A sleeve is inserted between the tubes, at the distal end, and the sleeve is then bonded to both tubes. The hubs are also bonded together. Thus, the tubes are firmly joined to each other, but only at their distal and proximal ends. The outer tube has a plurality of holes, located around its circumference, at the distal end, to provide access to the outer lumen. The distal tip provides an exit port for the inner lumen. The catheter can also be provided with a dilator/stylet which is initially inserted within the inner lumen, and which is withdrawn after the catheter has been inserted into a patient.
