1. A system for aspirating thrombi using an operator-selectable suction pattern, the system comprising:
- an external control panel that allows an operator to choose from any of a plurality of stored crescendo suction patterns during a thrombus aspiration procedure,wherein each of the plurality of stored crescendo suction patterns comprises a repetitive cycle pattern having at least two different suction intensity levels,wherein the at least two different suction intensity levels are selected from one of three suction intensity levels,wherein a first suction intensity level is within a range between −
100 and −
350 mm Hg, wherein a second suction intensity level is within a range between −
351 and −
550 mm Hg, and wherein a third suction intensity level is within a range between −
551 and −
769 mm Hg,wherein a first suction pattern of the plurality of stored crescendo suction patterns is configured for aspiration of soft clots,wherein a second suction pattern of the plurality of stored crescendo suction patterns is configured for aspiration of hard clots; and
a vacuum pump comprising power electronics that generate the plurality of stored crescendo suction patterns.

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.
