1. A catheter for insertion into the human body comprising:
- an elongate tubular shaft formed from at least one film of material rolled into an elongate tube having a plurality of layers and permanently fixed in said rolled configuration;
said shaft being formed from a biocompatible material and having a proximal end and a distal end, the shaft being constructed to enable the distal end to be inserted into the body of a human patient;
a fitting attached to the proximal end of the shaft;
said catheter including means at the distal end of the shaft for treating a medical condition of the patient, the catheter being manipulable from the proximal portion thereof disposed outside of the patient'"'"'s body.

Abstract
A catheter shaft and catheter are formed by spirally rolling a thin polymeric film about a mandrel into a tubular form and fixing the spirally wound film in the tubular form. Additional elements and films may be incorporated into the spirally wound tube to provide a catheter having varied characteristics and functions.
