Abstract:
A controllable stiffness catheter comprises a shaft comprising an inner sheath defining an access lumen, an outer sheath surrounding the inner sheath and defining an annulus therebetween, the annulus having a vacuum connection at which a vacuum is applied to the annulus, and a mechanical stiffener disposed at least at a portion of the annulus and free to move relatively in the annulus with respect to at least one of the inner sheath and the outer sheath.

Claim (Index 9):
The catheter according to  claim 1 , wherein a magnitude of a pressure change between an outside of the shaft and the interior of the annulus affects stiffness of the shaft such that, as the pressure difference increases, the stiffness at least at the portion increases.
