    Abstract: A spray device includes side-by-side spray tips that are spaced from one another at a distal end of the spray device. A first spray tip has a first fluid pathway defining a first flow area. The first fluid pathway has a first swirl chamber having an outer perimeter and flutes having inner ends that direct a first fluid into the outer perimeter of the first swirl chamber for rotating the first fluid in a circular pattern. A second spray tip has a second fluid pathway that defines a second flow area that is larger than the first flow area. The second fluid pathway has a second swirl chamber having an outer perimeter and flutes having inner ends that direct a second fluid into the outer perimeter of the second swirl chamber for rotating the second fluid in a circular pattern.

    Abstract: 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.

    Abstract: An applicator instrument for dispensing surgical fasteners includes an elongated shaft, a housing connected with the elongated shaft, a trigger, a gear train, and a firing system disposed in the housing. The trigger is squeezed for commencing a firing cycle. The firing system includes a storage reel, a spool connected to the storage reel, a drive wheel located distal to the storage reel and the spool, a constant torque spring having a proximal end connected to the spool and a distal end connected to the drive wheel, and a flexible member in contact with the drive wheel. The flexible member has a proximal end connected to the storage reel and a length configured to be driven by the drive wheel toward the distal end of the elongated shaft. During an energy storing stage, the gear train is coupled with the storage reel for rotating the storage reel in a counterclockwise direction, which, in turn, retracts and winds the flexible member onto the storage reel, which rotates the drive wheel in a counterclockwise direction and winds the constant torque spring from the spool onto the drive wheel for storing energy in the constant torque spring.

    Abstract: A surgical fastener includes a first leg having a first distal barb and a first proximal barb that extend inwardly, and a second leg having a second distal barb and a second proximal barb that extend inwardly. A bridge interconnects proximal ends of the first and second legs. A first distance between opposing inner tips of the first and second distal barbs is greater than a second distance between opposing inner tips of the first and second proximal barbs. The first leg tapers inwardly between the proximal and distal ends thereof and has a cross-sectional area that is greater at the proximal end than at the distal end. The second leg tapers inwardly between the proximal and distal ends thereof and has a cross-sectional area that is greater at the proximal end than at the distal end. An insertion tool engages a crown on the proximal side of the bridge.

    Abstract: An applicator instrument for dispensing surgical fasteners includes a housing having a cartridge opening, an elongated shaft extending from the housing, and a cartridge insertable into the cartridge opening, the cartridge having a plurality of surgical fasteners pre-loaded into the cartridge. The applicator instrument has a firing system disposed within the housing, and an actuator for activating the firing system to commence a firing cycle for removing one of the surgical fasteners from the cartridge and driving the removed surgical fastener from the housing to a distal end of the elongated shaft. In one embodiment, the cartridge includes a cartridge body having an upper end and a lower end insertable into the cartridge opening. The surgical fasteners are arrayed in a stack that extends between the upper and lower ends of the cartridge body. The cartridge has a constant force spring that normally urges the stack of surgical fasteners toward the lower end of the cartridge body for being fed into the firing system.
