Abstract:
A controllable stiffness catheter comprising 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.

Claim (Index 43):
A controllable stiffness catheter, comprising:\n a shaft comprising:\n an inner sheath defining an access lumen; \n an outer sheath surrounding the inner sheath and defining an annulus therebetween, the annulus comprising a proximal portion having a vacuum connection at which a vacuum is applied to the annulus; \n a mechanical stiffener disposed at least at a longitudinal portion of the annulus, the inner and outer sheaths and the mechanical stiffener being sized to have at least the longitudinal portion sized for neurological vascular procedures; and \n a vacuum device fluidically connected to the vacuum connection and configured to apply the vacuum to the annulus and, responsive to the vacuum being applied to the vacuum connection:\n pressure is lowered within the annulus; \n the outer sheath contacts the mechanical stiffener; and \n responsive to the vacuum being applied to the annulus through the vacuum connection, the shaft is stiffened at least at the longitudinal portion at which the mechanical stiffener is disposed without substantially straightening the shaft at the longitudinal portion.
