Claim Text:
1. A biopsy device comprising: a moveable hub coupled to a first end of a cannula and having a needle port and a vacuum port, the vacuum port being in communication with the cannula; a vacuum line in communication with the vacuum port; a stationary housing surrounding a portion of the cannula between the first end and an opposing second end, the stationary housing being distal to the hub and separated by a distance from the hub; and a biasing member coupled with the moveable hub and the stationary housing, the biasing member extending from the moveable hub to the stationary housing along the distance, and the biasing member imparting a biasing force on the hub in a direction away from the stationary housing, wherein an application of force on the hub sufficient to overcome the biasing force of the biasing member translates the moveable hub and the cannula in a direction toward the stationary housing, and wherein when the cannula is inserted in the body of the patient, a vacuum is provided via the vacuum line to aspirate liquid and cellular samples from the body of the patient into the cannula.
