Abstract
Catheters which utilize a flexible tube that has been modified at one end or both ends. Such modifications involve modifying a tube end to increase rigidity and strength (while maintaining some flexibility), or involve special placement of an intraluminal cord within the tube. One such catheter has a tube (20) with a cord (26) running therethrough wherein a portion of the tube's proximal end has been reinforced (30), preferably, in such a manner that the reinforced portion of the tube remains flexible. Similarly, another catheter includes a tube having an associated intraluminal cord, wherein the cord is affixed to the interior of the tube's proximal end. Another catheter has a tube and intraluminal cord with an enlarged end (e.g. a ball (28)) extending from the tube's distal end, and is modified by incorporating, within the tube's distal end, a spring (30). The thus placed spring (30) acts to increase the rigidity of the tip of the device, and interacts with the ball if need be to collect a portion of the tube which may break off from the remainder of the tube after placement.
