Abstract: In some embodiments, without limitation, the invention comprises a catheter having an elongated housing with a channel disposed therein. A laser delivery member is movable and at least partially disposed within the channel. A ramp is disposed within the housing at an angle to its central axis and proximate to its distal end. The ramp is adapted to move the distal end of the laser delivery member outwardly from the central axis of the housing. A guidewire biases the distal end of the laser delivery member generally inwardly toward the central axis of the housing. In some embodiments, without limitation, the offset of the central axis of the tip of the laser delivery member from the central axis of the housing is determined by adjusting the extent to which the laser delivery member travels on the ramp, and disposition of the laser delivery member on the guidewire maintains the offset tip substantially parallel to the central axis of the housing.

The set of interaction options is initiated based upon the detected presence of the chargeable device on the charging surface and the identified device type and, the output signal is presented on a display of the charging device.

Abstract: A device for delivering fluid, such as insulin for example, to a patient. The device includes a flow path having an exit port assembly adapted to connect to a transcutaneous patient access tool, and a reservoir connected to the exit port assembly. The device also includes a flow restriction system having an air removal filter communicating with the flow path and allowing air to exit the flow path and preventing fluid from exiting the flow path, and a flow restrictor positioned within the flow path between the air removal filter and the exit port assembly. Among other features and advantages, the flow restriction system of the present invention allows the flow path of the fluid delivery device to be purged of air, or “primed” prior to operation, such that desired volumes of fluid can be accurately delivered by the device.
