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catheter can also be provided with a dilator/stylet which is initially inserted within the inner lumen, and which is withdrawn after the catheter has been inserted into a patient.
摘要翻译：双腔导管由两个大体上同轴的管制成。这些管在其远端处通过插入在管之间的套筒连接，套筒连接到两个管。内管和外管分别在其近端连接到第一和第二毂。集线器结合在一起。管的远端可以形成为锥形尖端，优选地具有圆形边缘。管的近端可以连接到外部流体装置。本发明还包括制造导管的方法。根据该方法，分别形成内管和外管，并且每个管的近端连接到毂。然后，将内管拧入外管，直到管的远端彼此靠近。在管之间插入套管，在远端处，然后将套筒粘合到两个管上。轮毂也结合在一起。因此，管彼此牢固地接合，但仅在其远端和近端处。外管在远端处具有围绕其圆周设置的多个孔，以提供对外腔的通路。远端提供用于内腔的出口。导管还可以设置有最初插入内腔内的扩张器/管心针，并且在导管插入患者体内之后将其取出。
