    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 assembly including a surgical introducer having a handle portion and a needle element extending to a free distal end, and a sliding mechanism including a compressible member and a sliding button slidably coupled to the handle portion for longitudinal movement relative thereto and having a first retaining device extending outwardly from a distal end and a projection extending outwardly to a position adjacent the compressible member. First and second sheath elements each have a proximal end, a closed tapered distal end region, a channel therein, and a side aperture at a predetermined distance from the distal tip. The needle element slidably extends through the side aperture and into the channel of the first sheath element. An implant having first and second ends is coupled to the proximal ends of the first and second sheath elements respectively. The sliding button is slidable between a first resting position and a second more distal position wherein the retaining element can engage the side aperture, and wherein when so engaged the compressible member exerts a constant force on the sliding button and sheath element in a direction toward the first resting position of the sliding button.

    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.
