ABSTRACT:
A catheter, having a substantially fluid-tight seal is provided. The seal can be used in a number of catheters, including an angioplasty catheter. The seal includes surfaces that are independently movable relative to one another. The effectiveness of the seal depends on the proximity of the surfaces, the surface are at the interface, pressure differential and viscosity of the fluid. The seal is used in connection with providing fluid-tight channels with surfaces that are relatively movable and to circumvent the need to separate hydraulic channels from other channels so that catheters can be provided with fewer channels. Further, catheters and catheter systems with smaller shaft dimensions or larger hydraulic channel dimensions is made possible. Balloon catheters using this seal have enhanced torque delivery and directional control.
