ABSTRACT:
A balloon dissector in which an elastic balloon is positioned on an exterior portion of a rigid tube. The tube is inserted into the patient and then a medium, such as saline solution, is inserted into the hollow tube. The medium is communicated to an interior portion of the elastic balloon causing the balloon to expand and dissect tissue in the area. This dissection permits a subsequent surgical procedure to be performed at the site. Since the tube is rigid, one end of the tube is preferably shaped as a dissector. The rigid tube is graspable by the surgeon and is used as an instrument during its insertion into the site. The rigid tube, in one embodiment of the invention, is rigidly affixed to a syringe containing the medium so that the syringe/tube form one unit which is manipulated by the surgeon.
