Publication number: 20220218339Abstract: An applicator instrument for dispensing surgical fasteners includes a housing, an elongated shaft, surgical fasteners disposed in the elongated shaft, a firing system for dispensing the surgical fasteners, a firing rod disposed within the elongated shaft and movable within a first plane, and an advancer disposed within the elongated shaft and moveable within a second plane. An actuator is coupled with the advancer for moving the advancer back and forth between retracted and extended positions. A staging assembly at the distal end of the elongated shaft aligns a leading surgical fastener with the first plane. The staging assembly includes a biasing device that is configured to be deflected away from the first plane by the advancer when the advancer is in the extended position and the staging assembly is configured to spring back into alignment with the first plane when the advancer returns back to the retracted position.Type: ApplicationFiled: March 29, 2022Publication date: July 14, 2022Inventors: Simon Cohn, Michael Cardinale, Richard P.

Patent number: 10729433Abstract: An applicator instrument for dispensing surgical fasteners includes a housing having an actuator and an elongated shaft extending from the housing. The applicator instrument includes a top stamping disposed within the elongated shaft, and a bottom stamping disposed within the elongated shaft that opposes the top stamping. The applicator instrument has a firing system for dispensing at least one surgical fastener from the distal end of the elongated shaft. An end cap is assembled with the distal ends of the top stamping, the bottom stamping, and the elongated shaft for stabilizing the distal end of the applicator instrument. The end cap has a distal end face with castling for engaging an opposing surface such as surgical mesh overlying tissue. The castling prevents the distal end of the applicator instrument from sliding or moving relative to the opposing surface.Type: GrantFiled: October 21, 2016Date of Patent: August 4, 2020Assignee: Ethicon, Inc.Inventors: Simon Cohn, Robert Nering, Anthony Miksza, Matthew Rohr Daniel, Jeremy David Jarrett, Richard P.
