摘要：
A deflectable medical device incorporates a strut that is configured to reduce or eliminate axial shortening of the deflectable portion of the medical device, for example, the deflectable distal end portion of a catheter or access sheath. The strut may is coaxially disposed in the medical device in the section that is contemplated to undergo the repeated deflection. The strut provides improved column strength and axial restoration. The strut may be stent-like device, an elongate device having opposing ends coupled by a connecting lattice involving a plurality of helical connecting elements or a tube having a plurality of circumferentially-extending slots arranged in longitudinally-extending rows.
