Abstract
A tissue sampling device (10) for retrieving one or more tissue samples from a patient is either handheld or mounted to a moveable carriage (184) and advanced so that the needle tip (152) is introduced into the patient. The needle tip (152) is advanced until the tissue receiving basket (154) reaches the tissue sample target zone (190). Vacuum pressure is supplied to the basket (154) via a vacuum tube (144) so that tissue to be sampled is drawn into the basket (154). The cutter (42) is rotated and advanced linearly to cut a tissue sample (212) which is then retrieved by retracting the needle (40).
