Abstract: An improved surgical device having unique aspiration and instrument control is disclosed. The device is adapted for one-handed simultaneous or alternate dissection and aspiration through a novel combination of control elements. The device is particularly well-suited for neurosurgery and microsurgery.

Abstract: A protective device for preventing the development of postoperative adhesions between a patient's dura and spinal nerves and other anatomic structures after spinal surgery. Preferably, the protective device provides an intervening barrier between portions of the patient's dura and spinal nerves in the patient's spinal canal following intervertebral disc surgery in which a portion of one of the patient's intervertebral discs and a portion of the patient's vertebra adjacent the disc are removed.
