  • Publication number: 20230309978
    Abstract: A mixing and spraying assembly for a tissue sealant includes a mixing assembly, a spray tip assembly, and a malleable section having a proximal end connected with the mixing assembly and a distal end connected with the spray tip assembly for enabling the spray tip assembly to be angulated relative to the mixing assembly. The malleable section includes a flexible shaft having a length, a malleable wire conduit that extends along the length of the flexible shaft, and a malleable wire disposed in the malleable wire conduit. The malleable wire is longer than the flexible shaft and has a proximal end that is connected to the mixing assembly and a distal end that is connected to the spray tip assembly. First and second fluids are mixed within the mixing assembly to form a tissue sealant that is delivered through the malleable section for being expressed from the spray tip assembly.

  • Publication number: 20230035583
    Abstract: A method of dispensing surgical fasteners includes providing an applicator instrument having a housing with a cartridge opening, an elongated shaft extending from the housing, a firing system disposed within the housing for dispensing surgical fasteners, and an actuator for activating the firing system. The method includes forming a surgical opening in tissue, inserting a distal end of the elongated shaft into the surgical opening, inserting a cartridge containing a plurality of first surgical fasteners into the cartridge opening, and engaging the actuator for dispensing one of the first surgical fasteners from the distal end of the elongated shaft.

  • Publication number: 20220313948
    Abstract: A dispensing system includes a hollow tube having an outer wall with an air vent formed in the outer wall. A valve including a flexible flap is disposed inside the tube. The flexible flap, normally biased into a retracted position, is moveable between an extended position for sealing the air vent and the retracted position for unsealing the air vent. A syringe connector interconnects a syringe with the proximal end of the hollow tube and defines a fluid flow path. A flowable viscous fluid is disposed within the syringe. When a syringe plunger is depressed, the flowable viscous fluid is expelled from the syringe and forced through the fluid flow path and into the proximal end of the hollow tube. When the flowable viscous fluid engages the flexible flap, the flexible flap is forced to move into a position that seals the air vent.

  • Patent number: 10667806
    Abstract: An applicator instrument having a reconfigurable handle for dispensing surgical fasteners includes a housing having a proximal end and a distal end, an elongated shaft extending from the housing, a handle coupled with the proximal end of the housing, and a trigger coupled with the handle. The applicator instrument has a firing system including an energy storing assembly that is disposed within the housing, and a gear train disposed within the handle and coupled with the trigger. The trigger is squeezed for commencing a firing cycle and storing energy in the energy storing assembly. The applicator instrument includes a handle reconfiguration actuator having a first position for locking the handle in place relative to the housing and a second position for enabling the handle to rotate relative to the housing between a pistol configuration and an in-line configuration.

  • Patent number: 10588622
    Abstract: An applicator instrument for dispensing surgical fasteners includes a housing, an elongated shaft having a proximal shaft section and an articulating distal shaft section extending from the housing, a firing system disposed within the housing, an actuator that is engageable for commencing a firing cycle of the firing system, and an articulation lever provided on the housing for selectively articulating the articulating distal shaft section of the elongated shaft. The applicator instrument includes a cam plate disposed within the housing that is linked with the articulating distal shaft section and that coupled with the articulation lever for being rotated by the articulation lever between a first or horizontal position for straightening the articulating distal shaft section and a second or vertical position for articulating the articulating distal shaft section.
