Abstract
The invention is a catheter, which is formed from flexible material and has two basic configurations: An initial configuration, in which the catheter is supplied to the surgeon for insertion into the lumen of a patient, resembles a tension coil spring and a final configuration, which is an essentially linear configuration that is much longer and has a considerably smaller outer diameter than when it is in its initial configuration. The catheter is adapted to undergo a transformation from the initial configuration to the final configuration as it is pulled from its proximal end in order to withdraw it from the lumen of the patient.
