  • Methods and systems for managing mixed mode electromechanical actuator drive
    Patent number: 11765499
    Abstract: In accordance with embodiments of the present disclosure, a method of driving a playback waveform to an electromagnetic actuator by a transducer driving system may include operating the transducer driving system in a first mode wherein the electromagnetic actuator is driven with the playback waveform in a closed loop to form a closed-loop voltage drive system that includes a negative impedance, operating the transducer driving system in a second mode wherein the electromechanical actuator is driven with the playback waveform in an open loop, and operating a mode switch for transitioning the transducer driving system to operate between the first mode and the second mode.

  • LOCKING ASSEMBLY FOR COUPLING GUIDEWIRE TO DELIVERY SYSTEM
    Publication number: 20220218503
    Abstract: A locking assembly for releasably coupling a first elongate member to a second elongate member is provided. The locking assembly can include a first lumen for anchoring the locking assembly to a catheter and a second lumen for releasably retaining a guidewire to the locking assembly. A release member can interface with the locking assembly and apply a force that decouples the guidewire from the locking assembly.
