Abstract TITLE BODY TISSUE PENETRATING METHOD AND APPARATUS INVENTORS CESAR A. ROMERO-SIERRA ZENON JENNINGS JOSEPH WARWICK ABSTRACT OF THE DISCLOSURE A method and apparatus for making passageways through body tissue to provide access for a surgical operation beneath the tissue and comprises inserting a vibrating tissue penetrating probe into the tissue, inserting a tubular tissue separating member into the passageway and manipulating the member to separate tissue fibers and enlarge the passageway, and if required successively inserting separating members of increasing cross-section to further enlarge the passageway. A frustoconical tubular member may be used for further enlargement and retained in the passageway as a shield to provide an unobstructed passageway for a surgical operation. The invention alleviates bleeding and other deleterious post-operative effects of incisions. .
An apparatus for making a passageway in body tissue comprising: (a) a tissue penetrating probe comprising an elongated member having a blunt end; (b) a vibrating device for detachably connecting to the other end of the probe; and (c) a tubular tissue separating member for slidably positioning over said penetrating probe and for introducing into the tissue to enlarge the passageway formed by the probe.
