  • Patent number: 11284900
    Abstract: Devices, systems, and methods for inflation are provided. Inflation devices include a housing, a compressed gas canister disposed therein, a syringe disposed within the housing, a plunger slidably disposed in the syringe having an unloaded position and a loaded position relative to the syringe, a puncture mechanism disposed within the housing and configured to open a fluid path between the compressed gas canister and the syringe, and a positive pressure mechanism disposed within the housing and operably coupled to the syringe. Engagement of the puncture mechanism puts the syringe into fluid communication with the compressed gas canister such that gas contained therein loads into the syringe and the plunger moves from the unloaded position and the loaded position. The positive pressure mechanism is configured to maintain the gas within the syringe at a positive pressure relative to ambient pressure in order to prevent air from entering the syringe after loading.

  • Patent number: 11272920
    Abstract: Surgical constructs and methods of use for a one-way adjustable fixation loop are formed by tying two knots in a surgical filament, each knot defining an individual adjustable loop and the individual adjustable loops being interconnected to form the one-way adjustable fixation loop. The knots enable a non-spliceable suture to be used in the creation of the one-way adjustable fixable loop. Embodiments can include a fixation device, such as a cortical button or plate for use in a bone tunnel, and enable the knots to work independent of and suspended below the fixation device. Embodiments can increase the compatibility of the adjustable fixation loop with existing fixation devices and can isolate and protect the knots from damage during use and after implantation.
