Abstract: 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.

Abstract: 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.

Abstract: A SAS expander includes a switch core, a number of SAS expander phys coupled to the switch core, an SMP originator coupled to the switch core and an SMP receptor coupled to the switch core. In an embodiment, the SMP originator is configured to only send connection requests and the SMP receptor is configured to only receive connection requests. Program instructions stored in non-transient digital storage media include code segments detecting a new connection request, code segments determining whether the new connection request is in conflict with an existing connection request and code segments determining if there is a free destination receptor phy. In an embodiment, the free destination receptor phy is never operationally used for an origination of a connection request.

Abstract: 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 that propagate through the liquid for impinging upon the valve. The shock wave generator is moveable within the balloon to vary shock wave impingement on the valve.

Abstract: Disclosed herein are intravascular systems and methods for modulating the activation of neural activity using shock wave devices. In one embodiment, the system is used to treat the nerves in the renal plexus. In a second embodiment, the system is used to treat the baroreceptors in the carotid sinus. In a preferred embodiment, the shock wave generator is in the form of electrodes mounted within an inflatable balloon.

Abstract: A catheter, for use, for example, in valvuloplasty, includes an elongated body and an inflatable balloon carried by the elongated body. The balloon has an inner surface and an outer surface. The catheter further includes at least one shock wave source within the inflatable balloon and a follower arrangement that maintains the at least one shock wave source a substantially fixed distance from the inner surface of the balloon.

Abstract: A guide wire, for use, for example, in guiding an elongated catheter through an artery or vein of a mammalian body having a stenosis and/or an occlusion therein, includes an elongated conductor having a longitudinal dimension, a proximal end and a distal end. The guide wire further includes an insulator overlying the elongated conductor. The insulator exposes a portion of the longitudinal dimension of the elongated conductor to form an electrode. The elongated conductor is arranged to be connected to a source of high voltage pulses to cause electrical arcs at the electrode that in turn form steam bubbles and shock waves to break the stenosis and/or open the occlusion and permit the guide wire to pass there through. Other embodiments are directed to a system including the guide wire and a method of using the guide wire.

Abstract: A catheter comprises an elongated carrier and a balloon carried by the carrier in sealed relation thereto. The balloon has an outer surface and is arranged to receive a fluid therein that inflates the balloon. The catheter further comprises a shock wave generator within the balloon that forms mechanical shock waves within the balloon, and a medicinal agent carried on the outer surface of the balloon. The medicinal agent is releasable from the balloon by the shock waves.

Abstract: A system for breaking obstructions in body lumens 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 an arc generator including at least one electrode within the balloon that forms a mechanical shock wave within the balloon. The system further includes a power source that provides electrical energy to the arc generator.

Abstract: A pocket sized dispenser houses in coiled form a flexible strip of portions of smokeless tobacco sized for placement between a consumer's cheek and gum, where the flexible strip includes a base tape removably attached to the plurality of portions, and wherein the dispenser and strip are adapted to allow a consumer to separate individual portions from the base tape. The individual portions comprise either a collection of tobacco particles at least partially enclosed by a coating comprising a water-soluble non-crosslinked component and a substantially water-insoluble cross-linked component; or pouches attached to the base tape with a food-grade adhesive, the pouches comprising smokeless tobacco enclosed in a water-permeable wrapper with at least one lap-sealed edge. Methods of preparing such are disclosed.

Abstract: An angioplasty catheter includes an elongated carrier, and an angioplasty balloon about the carrier in sealed relation thereto. The balloon is arranged to receive a fluid therein that inflates the balloon. The catheter further includes a shock wave generator within the balloon that forms a rapidly expanding and collapsing bubble within the balloon to form mechanical shock waves within the balloon. The expanding bubble forms a first shock and the collapsing balloon forms a second shock wave. The shock wave generator is arranged such that the energy of the first shock wave is greater than the energy of the second shock wave.

Abstract: 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.
