ABSTRACT:
A tubing assembly is provided which includes a length of elastomeric tubing over which is positioned and affixed a substantially shorter length of tubing having micro orifices ion sputtered therethrough. The tubing assembly is manufactured by a method that includes stretching the elastomeric tubing in association with the application of medical adhesive at an interface between the elastomeric tubing and the ion sputtered tubing, and relaxing the elastomeric tubing to provide an effective seal along the ends of the ion sputtered tubing. These tubing assemblies are particularly suitable for use as ventricular catheters within intracranial pressure relief systems.
