Publication number: 20120046689Abstract: 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.Type: ApplicationFiled: October 31, 2011Publication date: February 23, 2012Applicant: Tyco Healthcare Group LPInventors: Christopher J.
