ABSTRACT:
A partially collapsible catheter is formed as a substantially-flattened tube of flexible, collapsible plastic; a spacing member disposed within such tube allows the tube to substantially flatten and collapse in the absence of infusion fluid, but maintains at least one channel open within the tube for allowing fluid to be aspirated therethrough. During infusion, infusion fluid expands the catheter to a generally rounded configuration. The spacing member can be incorporated within a single lumen catheter; alternatively, the spacing member can divide the tube into first and second lumens for providing a dual lumen catheter.
