    摘要: The present disclosure comprises handle assemblies for intravascular treatment devices. In one embodiment, a handle assembly comprises an actuator for deflecting a distal region of an intravascular treatment device. In one embodiment, a handle assembly comprises a rotator for rotating an intravascular treatment device independently of the handle assembly. In one embodiment, a handle assembly comprises a rotation limiting element for limiting independent rotation of an intravascular treatment device relative to the handle assembly. Methods and systems for intravascular delivery, deflection and placement of an intravascular treatment device via a handle assembly of the present invention are also provided.

    摘要: Systems and methods are disclosed to detect current for an output load with an inductor. The system includes a high side power transistor a low side power transistor coupled to the high side power transistor; and a controller coupled to the high and low side power transistors to provide cycle by cycle conduction of the low side power transistor, said controller adaptively turning off the low side power transistor when the high and low side power transistors are off and an inductor current is non-positive. Adaptation of the turn off of the low side transistor is based on the time position of the detection of the non-positive inductor current and serves to improve the power efficiency of the system.

    摘要: A regulator with a high side pass device and a low side pass device coupled in series to the high side pass device is disclosed. The apparatus further includes a control module coupled to the high side pass device and the low side pass device. The control module is coupled to the high side pass device and the low side pass device to control the high side pass device and the low side pass device. The control module is operable to lock out the high side pass device under certain conditions.
