A thrombectomy system includes a catheter having a proximal end and a distal end, a valve in fluid communication with the catheter, and a cutting instrument associated with the distal end of the catheter. The cutting instrument may be configured for axial and/or rotational motion. A controller of the system may be configured to detect operational parameters of the cutting instrument. The controller may determine whether the cutting instrument is engaging with occlusive material based on the detected operational parameters. The controller may operate the valve in one or more operating modes to alter a level of pressure in the catheter based on whether the cutting instrument is engaging with the occlusive material.
