ABSTRACT:
A collapse-resistant catheter adapted for medical usage includes a central tube having a smooth outer wall rather than a corrugated outer wall characteristic of prior art collapse-resistant catheters. The tube includes an integral, spiral-shaped outer tube which provides the collapse-resistant characteristic. The spiral tube also provides an additional lumen. The center tube is adapted to provide for a multilumen structure not possible with corrugated prior art structures. The resulting structure, single or multilumen, can be made sufficiently small for insertion into the human body.
