Abstract:
Superselective catheterization of even very tortuous vessels is possible, with very low risk of arterial spasm and plication of the catheter, when very flexible catheters are used. The thermoplasticity as a new additional quality of very flexible catheters offers new possibilities to guide such catheters. Thus, the catheter extremity may be curved in order to overcome difficult anatomic pathways, or a bulb-shaped dilatation of the catheter tip can be achieved in order to increase the flow-dependent guidance of the catheter.
