Abstract: A catheter system for treating stenosis in a body lumen includes a first energy source, a second energy source, and a catheter. The catheter includes an elongate member that is navigable through the body lumen, a first acoustic energy emitter connected to the first energy source and configured to emit acoustic energy when energy is received from the first energy source, and a second acoustic energy emitter connected to the second energy source and configured to emit acoustic energy when energy is received from the second energy source.

Abstract: The embodiments herein relate to apparatuses and methods for electroplating one or more materials onto a substrate. Embodiments herein utilize a cross flow conduit in the electroplating cell to divert flow of fluid from a region between a substrate and a channeled ionically resistive plate positioned near the substrate down to a level lower than level of fluid in a fluid containment unit for collecting overflow fluid from the plating system for recirculation. The cross flow conduit can include channels cut into components of the plating cell to allow diverted flow, or can include an attachable diversion device mountable to an existing plating cell to divert flow downwards to the fluid containment unit. Embodiments also include a flow restrictor which may be a plate or a pressure relief valve for modulating flow of fluid in the cross flow conduit during plating.

Abstract: A back pack for in-line skates includes a relatively large central compartment having a lateral shape in section somewhat resembling that of an in-line skate or ice skate with its integral boot. The sides of the central compartment include fixed loops and openable adjustable straps for removably securing one of a pair of skates to each side. The back of the central compartment includes a removable and adjustable helmet retaining net, providing for the removable retention of an in-line skating helmet or the like externally on the back of the pack. Additional smaller bottom, lower rear, and upper storage compartments may be removably or permanently attached to the central compartment. The pack includes adjustable padded shoulder strap loops extending from the upper front to the lower front of the central compartment, and a padded hip support belt extending from one side to the other across the front of the lower compartment.
