  • Publication number: 20120109157
    Abstract: A surgical fastener apparatus, for securing a surgical mesh material to body tissue including a pair of anchors each having retaining means formed on an outer surface thereof; and a suture tether interconnecting the pair of anchors to one another. The pair of anchors having a substantially cylindrical body having a conically tapered distal end and a planar proximal end. The retaining means includes a series of semi-circular angled projections having a planar proximal surface and a tapered distal end, wherein a center of each of the angled projections is spaced a distance from a longitudinal central axis of the body portion. The surgical fastener is made from a bioabsorbable material which reabsorbs into said body tissue at an appropriate rate, such as for example, polyglycolic acid and polylactic acid.

  • Publication number: 20120046689
    Abstract: A wound closure material applicator is provided which includes a handle assembly having a movable handle, a body portion extending distally from the handle assembly and a tip assembly supported adjacent the distal end of the body portion. The tip assembly includes a housing defining a bore, a tip member and a seal member. The tip assembly housing defines an inlet channel and a valve seat positioned adjacent the outlet of the inlet channel. The seal member is movable distally within the housing bore from a closed position in which the valve member abuts the valve seat to an open position in which the valve member is spaced from the valve seat. The tip assembly is configured such that movement of the seal member from the open to the closed position causes a reduction of pressure within a discharge channel of the tip assembly to minimize drippage of wound closure material from the applicator.
