摘要： A rotational atherectomy device for removing a stenotic tissue from a vessel of a patient is disclosed. The device comprises a rotatable, flexible, hollow drive shaft having a fluid impermeable wall defining a lumen of the drive shaft and, an abrasive element mounted to a distal end portion of the drive shaft proximal to and spaced away from a distal support element formed at a distal end of the drive shaft. The distal support element is inflatable by pressurized fluid which flows in an antegrade direction through said lumen of the drive shaft and is least partially re-directed into the distal fluid inflatable support element. The distal fluid inflatable support element has an outer wall comprising an outflow opening located such that said outflow opening faces an inner surface of a treated vessel during rotation of the drive shaft so that a flow of fluid through said outflow opening forms a layer of fluid between the outer wall of the rotating fluid inflated distal support element and a wall of the treated vessel to form a fluid bearing between the outer wall of the rotating fluid inflated distal support element and the wall of the treated vessel. The fluid impermeable drive shaft comprises at least one torque transmitting coil and at least one fluid impermeable membrane which extends beyond a distal end of the torque transmitting coil and conveys torque to the abrasive element mounted to the drive shaft distal to and spaced away from the distal end of the torque transmitting coil.

摘要： A rotational device for removing a stenotic lesion from within a vessel of a patient is disclosed. The device comprises a flexible hollow drive shaft having a distal end insertable into the vessel and an abrasive element located on the drive shaft proximal to the distal end of the drive shaft to abrade a stenotic lesion when the drive shaft rotates. The hollow drive shaft defines a lumen for fluid supplied into the drive shaft to flow in an antegrade direction along the lumen and into the vessel from the drive shaft distal to the abrasive element so that the fluid entering the vessel flows in a retrograde direction over the abrasive element and die drive shaft to entrain debris abraded by the abrasive element for removal of said debris from the patient.

摘要： A rotational atherectomy device for abrading a stenotic lesion from a vessel of a patient comprises a flexible drive shaft (1) which extends towards a distal end of the device, a distal fluid inflatable support element (3, 3″) located at a distal end of the drive shaft and an abrasive element (5) mounted to the drive shaft proximal to and spaced away from the distal fluid inflatable support element. Both the abrasive element and the distal fluid inflatable support element are rotatable together with the drive shaft and the drive shaft comprises a torque transmitting coil (2) which defines a long lumen of the drive shaft. The distal fluid inflatable support element is formed from a fluid impermeable membrane (9, 9″) that crosses a longitudinal axis (x-x) common to the torque transmitting coil and the lumen of the drive shaft at the distal end of the device, thereby preventing pressurized fluid flowing along the lumen of the drive shaft from entering the vessel in the direction of said longitudinal axis so that fluid has to pass through the fluid inflatable support element, inflating said support element and exiting from the device through an outflow opening (66) in the fluid inflatable support element in a direction different from the direction of the longitudinal axis of the coil and the lumen.
