More Information
Summary:Devices, systems, and methods for removing obstructions from body lumens are disclosed herein. In some embodiments, a system for removing a thrombus includes an interventional element configured to be disposed proximate to or adjacent to a thrombus within a blood vessel. The system can include a signal generator in electrical communication with the interventional element. The signal generator can be configured to deliver an electrical signal to the interventional element. The electrical signal can include a waveform having a positive phase having a peak positive current and a first duration, and a negative phase having a peak negative current and a second duration. A magnitude of the peak positive current can be greater than a magnitude of the peak negative current, and the first duration can be greater than the second duration.
