  • Patent number: 7722548
    Abstract: A soft tissue biopsy device is provided which allows for the recovery of a biopsy of tissue flat in shape, particularly suitable for lymph node biopsy. The device includes twin opposing primary blades preferably aligned in parallel planes, to cut the upper and lower surfaces of the biopsy. A detachment blade is provided to cut the side walls and distal ends of the biopsy. In a preferred embodiment, each primary blade has a sharpened tip set at an angle with a sharpened point to assist tissue penetration. The detachment blade, preferably has inwardly curving flexible sharpened tips at its distal end, and is attached to the handle at its proximal end by a slider such that when in a retracted position, the detachment blade is retracted from the tip of the twixt blades; and when in an advanced position, the tip of the detachment blade abuts the tip of the twin blades.

  • Patent number: 6875183
    Abstract: A biopsy needle for sampling bone marrow tissue, comprising a handle, and tissue sampling means comprising a sampling tube with a bore therein to receive a tissue sample, the outer surface of the sampling tube having an abrading formation extending in an axial direction along the tube, for abrading the sampled tissue, to permit the cannula tip to be laterally displaced whilst the tube is inserted into the bone marrow tissue. A biopsy needle for sampling bone marrow tissue, comprising a handle, tissue sampling means comprising a sampling tube with a bore therein to receive a tissue sample, and coupling means, separable from the needle, for coupling the needle to a rotary motor drive, whereby the needle is adaptable to both manual insertion and motor-assisted insertion.
