摘要： A rotational device for removing an occlusion from inside a tubular structure, the device comprising a drive shaft for insertion over a guidewire into a tubular structure and an abrasive element on the drive shaft having its centre of mass offset from a longitudinal axis of the drive shaft. A solid counterweight is disposed on the drive shaft spaced from the abrasive element and having its centre of mass offset from the longitudinal axis of the drive shaft so that the abrasive element moves in an orbital path around said axis to abrade an occlusion from inside the tubular structure when the drive shaft rotates around the guidewire.

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 method system and controller for controlling fluid flow in a rotational atherectomy device. A source of fluid is provided through a pump to the rotational atherectomy device, wherein the pump maintains the fluid flow at a minimal rate during a time period when a drive shaft of the device is not rotating. A first control is activated to increase a rate of the fluid flow and second control is activate to initiate a rotation of the drive shaft during another time period when the fluid flow is at the increased rate.

摘要： A rotational atherectomy device having a flexible, elongated, rotatable drive shaft with an eccentric enlarged diameter section. At least part of the eccentric enlarged diameter section has a tissue removing surface. The eccentric enlarged diameter section of the drive shaft has a center of mass and/or geometric center spaced radially from the rotational axis of the drive shaft, facilitating the ability of the device to open the stenotic lesion to a diameter substantially larger than the outer diameter of the enlarged diameter section.

摘要： A rotatable atherectomy device having an exchangeable drive shaft cartridge and a rotatable prime mover coupling. The cartridge has a rotatable drive shaft socket carried by a carriage. The coupling radially expands during rotation such that it interlocks with the socket to drive a tissue removal implement on the end of a drive shaft attached to the cartridge. Upon slow or no rotation of the socket, the coupling disengages from the socket to allow for exchange of the cartridge.

摘要： An ultrasound imaging balloon catheter for imaging near a wall of a cavity or passageway. The apparatus includes an elongated catheter having a primary lumen with a distal opening enveloped by the balloon. A pre-shaped ultrasound catheter carrying ultrasound transducer elements can be advanced through the catheter and inserted into the inflated balloon. The shape of the distal portion of the ultrasound catheter positions the ultrasound transducer elements radially outwardly of the catheter lumen, and preferably adjacent to the wall of the balloon, thus centering the image close to the wall of the cavity or passageway, giving greater depth of image at the portion of the wall of interest.
