Abstract
An aspiration control device may include a conduit having a distal end and a proximal end. The conduit may define a conduit lumen and an aperture vent open to the conduit lumen. A coupling may be configured to couple the proximal end of the conduit with a vacuum source and an inner cannula of a tissue cutting device. The inner cannula may define an inner cannula lumen wherein the vacuum source is configured to supply a vacuum to each of the coupling lumen and the inner cannula lumen. A sleeve may be movably disposed about the conduit, and a device motor may be in communication with the sleeve and be configured to move the sleeve to a predefined position relative to the vent in response to an input single from a user interface. The predefined position of the sleeve may correspond to a predefined level of vacuum to be supplied to the inner cannula lumen.
