摘要： Described herein are low-profile electrodes for use with an angioplasty shockwave catheter. A low-profile electrode assembly may have an inner electrode, an insulating layer disposed over the inner electrode such that an opening in the insulating layer is aligned with the inner electrode, and an outer electrode sheath disposed over the insulating layer such that an opening in the outer electrode sheath is coaxially aligned with the opening in the insulating layer. This layered configuration allows for the generation of shockwaves that propagate outward from the side of the catheter. In some variations, the electrode assembly has a second inner electrode, and the insulating layer and outer electrode may each have a second opening that are coaxially aligned with the second inner electrode. An angioplasty shockwave catheter may have a plurality of such low-profile electrode assemblies along its length to break up calcified plaques along a length of a vessel.

摘要： A valvuloplasty system comprises a balloon adapted to be placed adjacent leaflets of a valve. The balloon is inflatable with a liquid. The system further includes a shock wave generator within the balloon that produces shock waves. The shock waves propagate through the liquid and impinge upon the valve to decalcify and open the valve.

摘要： Described herein are shock wave devices and methods for the treatment of calcified heart valves. One variation of a shock wave device includes three balloons that are each sized and shaped to fit within a concave portion of a valve cusp when inflated with a liquid and a shock wave source within each of the three balloons. Each balloon is separately and/or independently inflatable, and each shock wave source is separately and/or independently controllable. Methods of treating calcified heart valves using a shock wave device can include advancing a shock wave device having one or more balloons and a shock wave source in each of the balloons to contact a heart valve, inflating the one or more balloons with a liquid such that the balloon is seated within a concave portion of a valve cusp, and activating the shock wave source.

摘要： A system includes a catheter including an elongated carrier, a balloon about the carrier in sealed relation thereto, the balloon being arranged to receive a fluid therein that inflates the balloon, and first and second electrodes within the balloon arranged to carry a voltage there-across including an initial high electrical voltage at an initial low current. The initial high electrical voltage causes an electrical arc to form across the first and second electrodes within the balloon. The electrical arc causes a gas bubble within the liquid, a high current to flow through the first and second electrodes, a decrease in the initial high electrical voltage, and a mechanical shock wave within the balloon. The system further includes a power source that provides the first and second electrodes with a drive voltage that creates the initial high electrical voltage at the initial current and that terminates the drive voltage in response to the decrease in the initial high electrical voltage.

摘要： A system that breaks calcium in a liquid includes a catheter including first and second electrodes arranged to receive there-across a high electrical voltage at an initial low current. The high electrical voltage causes an electrical arc to form across the electrodes creating a gas bubble within the liquid, a high current to flow through the electrodes, and a mechanical shock wave. A power source provides the electrodes with the high electrical voltage at the initial current and terminates the high electrical voltage in response to the high current flow through the electrodes.
