Abstract: A method for commissioning a synchronous or asynchronous electric motor having a stator and a rotor in which electrical power is applied to the motor when the rotor is stationary. The electric power is applied in two stages. The first stage utilizes a DC power that ramps in voltage over the duration of the first test to produce a current response that is employed to determine at least a first motor parameter. The second stage uses relatively high frequency AC power to generate one or more current responses that are employed to determine second and third motor parameters. A related electric motor drive system is also provided.

Abstract: A positioning device is provided for delivering or guiding a surgical device into a lumen of a body vessel to a position adjacent target tissue. The device includes a housing, an elongate sleeve, and a source of pressurized fluid. The sleeve has a first end coupled to a delivery side of the housing, a second end positioned on a return side of the housing, and an inverted distal portion positioned between the first and second ends. One second end of the sleeve can be furled about a support member supported on the housing. A distal portion of the sleeve defines a cavity that communicates with a pressure chamber within the housing. When pressurized fluid is directed into the pressure chamber, the pressurized fluid flows into the cavity of the distal portion of the sleeve to advance the sleeve away from the housing.
