Abstract
An aspiration system includes a pump and a control system in communication with the pump. The control system includes a microcontroller, an antenna configured to receive a signal, and a pump control board in communication with the microcontroller. The antenna is in communication with the microcontroller. Upon receiving the signal, the pump control board operates the pump to create negative pressure according to the signal.

A method of treating an intracerebral hemorrhage using a repetitive cyclical pattern for aspiration, the method comprising:
- inserting a distal end of a single-lumen cannula through a burr-hole in a skull;
- choosing the cyclical pattern from a plurality of provided cyclical patterns or customizing the cyclical pattern, the cyclical pattern comprising repetition of a first suction level, a second suction level different than the first suction level, and a third suction level different than the first suction level and the second suction level, wherein the cyclical pattern comprises a crescendo suction pattern or a diminuendo suction pattern;
- and
- aspirating blood through the cannula according to the chosen cyclical pattern by negative suction from a pump.
