Abstract
An aspiration device can be used to aspirate an obstruction from a blood vessel. The aspiration device is configured to allow controlled one-handed aspiration yet maintain a syringe plunger feel of vacuum. The aspiration device also allows one-handed injection to empty the device when needed. Furthermore, mechanisms enable one-handed locking of a plunger position of the device to maintain vacuum when the user releases the device.
