Abstract: A catheter system can include an electrical adapter and a catheter. The electrical adapter includes a hollow adapter body having a longitudinally extending channel and an electrical terminal positioned within the channel. The electrical adapter can be configured to connect to an energy source. The catheter can include an elongated body having a proximal end portion and a distal end portion, and an electrical connector coupled to the proximal end portion. The electrical connector forms the outer periphery of the catheter along a portion of the longitudinal length of the catheter. The electrical terminal and the electrical connector contact each other when the electrical connector is advanced through the channel to an electrical contact position in the channel, and are isolated from each other when the electrical connector is proximal of the electrical contact position.

Abstract: A catheter system can include a first catheter having an elongated body that defines a lumen, and a second catheter slidably disposed within the lumen of the first catheter. The second catheter can include an acoustic device. The acoustic device can create a sound for verifying the location of the second catheter within a body lumen. The distal end portion of the second catheter can include a pre-formed bend that extends at a non-zero angle relative to a longitudinal axis of the first catheter. In some embodiments, the second catheter can be used to aspirate a substance from a body lumen.

Abstract: A catheter system can include a first catheter including a first proximal end portion and a lumen. The first proximal end portion has a first key joint component that extends along a partial length of the first proximal end portion. The catheter system can also include a second catheter including a second key joint component that corresponds with the first key joint component. The first key joint component and the second key joint component are configured to be coupled together when the second catheter is slidably disposed within the lumen of the first catheter such that a rotational orientation of the second catheter is fixed relative to a rotational orientation of the first catheter. The first proximal end portion can be a fitting, and the first key joint component can include an opening defined by the fitting.

Abstract: A sprayer system for spraying liquid to fall on a desired area of ground includes a reservoir for storing a liquid and a pump adapted to draw the liquid from the reservoir. At least one operative nozzle is adapted to spray at least some of the liquid drawn from the reservoir by the pump onto the ground. A valve continuously varies the amount of the drawn liquid being supplied by the pump to the nozzle, and a flow-rate meter continuously measures the actual amount of liquid being supplied by the pump to the nozzle. A controller is operatively attached to the flow-rate meter and the valve, and includes a user input for entering a constant value corresponding to a preselected amount of liquid to be sprayer system over a preselected area. The controller is adapted to continuously determine the vehicle's rate of travel, and calculate the amount of liquid that must be supplied to the nozzle based on that rate to distribute evenly the preselected amount of liquid over the preselected area.
