1. Apparatus for applying at least one surgical fastener to body tissue, which comprises:

  • a) a frame;

    b) a tubular member connected to said frame and extending distally therefrom, said tubular member having a generally longitudinal axis, a proximal end portion, and a distal end portion;

    c) at least one surgical fastener supported by said tubular member;

    d) means for advancing said at least one surgical fastener distally for positioning adjacent the body tissue; and

    e) articulating means for pivoting said distal end portion to predetermined angles with respect to said generally longitudinal axis, said articulating means including;

    i) rotatable means rotatable about an axis generally transverse to said longitudinal axis and engageable with at least two pushrods movable in proximal and distal directions for engaging and pivoting the distal end portion, said rotatable means defining a generally V-shaped aperture; and

    ii) control means which includes a generally elongated member extending generally transverse to said longitudinal axis and received by said generally V-shaped aperture for operative engagement therewith whereby movement of said control means proximally and distally causes rotation of said rotatable means about said generally transverse axis to thereby move said push rods for pivoting the distal end portion.
