<p>The invention is generally directed to systems and methods for fluid cont rol, and more particularly to systems and methods for power and flow rate co ntrol for aspiration. In accordance with one embodiment, an aspiration syste m includes an aspiration line having distal and proximal ends and an aspirat ion port defined in the distal end; a fluid transport device operatively cou pled to the proximal end of the aspiration line; and a flow restrictor opera tively coupled to the aspiration line in between the fluid transport device and the aspiration port. To measure occlusion within the line, first and sec ond pressure sensors are utilized, the first sensor being operatively couple d to the aspiration line between the port and the restrictor and the second sensor being operatively coupled to the aspiration line between the restrict or and the fluid transport device. The pressure differential between the two sensors can provide an indication of the onset, presence, and/or eliminatio n of an occlusion.</p> |
