An intravascular catheter such as a dilatation catheter for angioplasty procedures having a removable distal shaft section. The catheter construction allows the original distal shaft section of the catheter to be removed and a replacement distal shaft section to be secured to the proximal section which is useful with angioplasty catheters when the dimensions of the balloon on the original distal shaft section are inappropriate for dilating a particular stenotic region. Such catheter construction is also useful when there is a need to implant a stent into a dilated stenotic region to maintain its patency.

Intravascular catheter with replaceable shaft section

The ventricular drainage system includes an antisiphon device comprising a flow through body which has an interior chamber and which is adapted to be positioned for vertical flow therethrough. The device further includes an inflow tract at the lower end of the body, adapted to be coupled to a ventricular catheter, and an outflow tract at the upper end of said body adapted to be coupled to a drainage tubing. The device also includes a ball in the chamber which is capable of closing the inflow tract when there is no flow of fluid from the ventricular catheter, capable of allowing fluid flow through the body during normal flow of liquid from the catheter and capable of closing the outflow tract upon a rush of fluid from the catheter.

External drainage antisiphon device

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.
