ABSTRACT:
A multilumen catheter having a distal portion with a soft tip and reduced cross-section. The multilumen catheter of the present invention includes a flexible, elongated first catheter tube and a flexible, elongated, dual-lumen catheter tube which has a first and second lumens integrally formed and is disposed within the first catheter tube. The cross-section of the dual-lumen catheter tube is smaller than that of the first catheter tube and therefore, an independent, single lumen is defined in the space between the first catheter tube and the dual-lumen catheter tube. The dual-lumen catheter tube extends beyond the distal end of the first catheter tube thereby providing an overall reduced cross-section of the distal portion of the present multilumen catheter. Furthermore, the dual-lumen catheter tube may be formed from a softer material than that of the first cathether tube thereby providing a softer distal portion of the present multilumen catheter. A protective hub encapsulates and secures the proximal ends of the first and dual-lumen catheter tubes, and facilitates fluid communication between each of the lumens and fluid transfer devices.
