Abstract
An aspiration control device may include a conduit having a distal end and a proximal end and defining a conduit lumen, wherein the conduit defines a vent that is open to the conduit lumen, a coupling configured to couple the proximal end of the conduit with a vacuum source and an inner cannula such that a vacuum is supplied to each of the conduit lumen and the inner cannula, a sleeve movably disposed about the conduit and configured to move relative to the vent to achieve a desired level of vacuum delivered to the inner cannula.
Claims20
An aspiration control device, comprising:
- a conduit having a distal end and a proximal end and defining a conduit lumen, wherein the conduit defines a vent that is open to the conduit lumen,
- a coupling configured to couple the proximal end of the conduit with a vacuum source and an inner cannula such that a vacuum is supplied to each of the conduit lumen and the inner cannula, and
- a sleeve movably disposed about the conduit and configured to move relative to the vent to achieve a desired level of vacuum delivered to the inner cannula.
A method of performing a neurosurgical procedure, comprising:
- providing an aspiration control device having:
- a conduit defining a conduit lumen and an vent open to the conduit lumen,
- a coupling configured to couple one end of the conduit with a vacuum source and an inner cannula such that a vacuum is supplied to each of the conduit lumen and the inner cannula,
- a sleeve movably disposed about the conduit ,and
- a motor device in communication with the sleeve, providing a signal to the motor from a user interface, and moving the sleeve relative to the vent via the motor device in response to the signal.
A method of performing a neurosurgical procedure, comprising:
- providing an aspiration control device having:
- a conduit defining a conduit lumen and an vent open to the conduit lumen,
- a coupling configured to couple one end of the conduit with a vacuum source and an inner cannula such that a vacuum is supplied to each of the conduit lumen and the inner cannula, and
- a sleeve movably disposed about the conduit, and
- moving the sleeve relative to the vent to achieve a desired level of vacuum delivered to the inner cannula.
