摘要： A multilumen catheter assembly is provided, which includes a unitary portion and at least two distal end tubes extending distally from the unitary portion. The unitary portion includes an exterior having a generally round or oval shape in cross section and includes at least two distal end tubes of generally circular (or other) cross sectional shape extending longitudinally therethrough. The catheter assembly may be made by extruding a unitary tube having internal longitudinally extending lumens (of circular or other shape), then splitting the tube on its distal end portion to form distal end tubes. The tubes are then ground and polished, the finished tubes retaining in combination the generally oval cross sectional shape of the unitary extrusion, or the finished tubes can each be finished to a circular, or other, cross sectional shape, or the finished tubes could include a combination of cross sectional shapes over its longitudinal length.

摘要： A co-axial catheter is disclosed. The catheter includes a first lumen having a first distal end, a first proximal end, and a longitudinal axis extending therethrough. The catheter further includes 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. The second distal end extends distally of the first distal end. The second distal end includes a distal tip and a bulbous projection disposed between the distal tip and the first distal end. A method of manufacturing and of inserting the catheter is also disclosed.

摘要： A multilumen catheter assembly and methods for making and inserting the same are provided. The catheter assembly includes a unitary catheter and at least two distal end tubes which extend distally from the unitary catheter. The at least two lumens in the unitary catheter are in fluid communication with passageways through the distal end tubes. The catheter assembly may be made by extruding a unitary catheter tube having internal longitudinally extending lumens, then splitting the tube on its distal end portion to form distal end tubes. The tubes are then ground and polished to form a smooth surface on the exterior of the tubes. The catheter assembly may also be made by forming an outer layer on at least two longitudinally extending catheters while leaving two distally extending portions of the tubes outside the outer layer to form the distal end tubes. The multilumen catheter assembly may be inserted in a patient for acute and chronic catheterization and subcutaneously tunneled and inserted using a single insertion procedure while leaving the distal end tubes within the vessel capable of free movement and sealing the insertion site into an area to be catheterized.
摘要翻译：提供了一种多腔导管组件及其制造和插入方法。导管组件包括整体导管和从整体导管向远端延伸的至少两个远端管。整体导管中的至少两个腔与通过远端管的通道流体连通。导管组件可以通过挤出具有内部纵向延伸的内腔的整体导管，然后在其远端部分上分裂管以形成远端管来制造。然后将管研磨和抛光以在管的外部形成光滑表面。导管组件也可以通过在至少两个纵向延伸的导管上形成外层，同时将管的两个远端延伸部分留在外层之外以形成远端管。多腔导管组件可以插入患者中用于急性和慢性导管插入，并且使用单次插入程序皮下穿刺并插入，同时将远端管留在容器内能够自由移动并将插入部位密封到待导管的区域中。
