Claim Text:
1. A tissue sampling device for removing tissue from a target area in the body comprising: a sheath having a proximal end, a distal end, and an inner surface extending between the proximal end and the distal end and defining a passage; an inner tube disposed within the passage of the sheath, the inner tube having a first end, a second end, an inner surface extending between the first end and the second end and defining a passage, and an outer surface spaced radially outward from the inner surface; and a cutting needle pivotally mounted to the inner tube, the cutting needle being pivotable between a first position radially inward of the inner surface of the sheath and extending into the passage of the inner tube and a second position extending radially outward of the inner surface of the sheath; wherein relative movement between the inner tube and the sheath causes the cutting needle to move between the first position and the second position, wherein rotation of the inner tube relative to the sheath when the cutting needle is in the second position causes the cutting needle to remove tissue from the target area in a helical path.
