Devices, methods and systems are described that enable achieving a working diameter that is greater than a resting diameter and to stimulate fluid circulation during high-speed rotation. The drag coefficient of the drive shaft is increased and, in some embodiments, the mass is increased. Among other advantages, the resulting drive shaft with an eccentric element integrated with and/or attached thereto will achieve orbital motion at a rotational speed that is less the rotational speed required to achieve orbital motion without the increased drag coefficient. The concomitant increase in fluid flow and/or fluid stirring at a comparatively lower rotational speed is a further advantage. These characteristics may allow, therefore, a smaller diameter abrasive element to be used which is advantageous in small and/or highly tortuous vessels.

Devices and methods for generating orbital motion in drive shafts for rotational medical devices

The present system is directed in various embodiments to methods, devices and systems for sensing, measuring and evaluating compliance in a bodily conduit. In other embodiments, the methods, devices and systems sense, measure, determine, display and/or interpret compliance in a bodily conduit and/or a lesion within the bodily conduit. In all embodiments, the sensing, measuring, determining, displaying and/or interpreting may occur before, during and/or after a procedure performed within the bodily conduit. An exemplary conduit comprises a blood vessel and an exemplary procedure comprises a vascular procedure such as atherectomy, angioplasty, stent placement and/or biovascular scaffolding.
