  • Publication number: 20250319260
    Abstract: Injector devices and methods for using them to deliver medicament into a patient's body, e.g., sub-retinally within an eye, are provided. The injector includes a cartridge including a piston slidably disposed within an interior for delivering medicament within the interior through an outlet, and a driver including a plunger coupled to the piston, a source of pressurized fluid, and an actuator member for opening a flow path at least partially between the source and the plunger to advance the plunger and piston to deliver medicament from the interior. One or more sensors are operatively coupled to the plunger to measure displacement of the plunger, a processor is coupled to the sensor(s) for analyzing sensor signals to measure volume of medicament delivered from the interior, and an output device, e.g., one or more LEDs or speakers, provide outputs related to the volume of medicament delivered.

  • Publication number: 20250144298
    Abstract: A method for assembling an auto-injector to minimize a gap between a plunger rod and syringe stopper is provided. A rear housing is provided that includes a gas canister and a plunger including a first end within a chamber of the rear housing and a second end extending from a distal end of the rear housing. A forward housing is provided including a syringe loaded into an interior thereof such that a syringe stopper is positioned adjacent a proximal end of the forward housing. The proximal end of the forward housing is aligned with the distal end of the rear housing such that the second end of the plunger is adjacent the stopper, and the housings are directed towards one another, the stopper causing the plunger to retract proximally within the rear housing to a proximal position to minimize a gap between the plunger and stopper.

  • Publication number: 20240417233
    Abstract: Gas canisters are provided that include an elongate body comprising a barrel region defining a first diameter, an enclosed first end, and a neck region extending from the barrel region to an open second end defining an end wall, the elongate body defining a central axis extending between the first end and the second end; a cap attached to the neck region to close the second end of the elongate body and enclose the cavity, the cap comprising an end wall including an opening therethrough communicating with the cavity, and a seat surrounding the opening on an interior of the end wall; and a sealing member within the neck region configured to engage the seat to seal the opening, the cavity filled with pressurized fluid.

  • Publication number: 20230355430
    Abstract: Injector devices and methods for using them to deliver medicament into a patient's body, e.g., sub-retinally within an eye, are provided. The injector includes an injector cannula having a soft injector tip. A retractable tip protector tube is slidably disposed on the flow cannula between an extended position in which the tip protector tube covers the entire injector tip, and a retracted position in which the tip protector tube is retracted proximally thereby exposing at least part of the injector tip. Accordingly, the tip protector tube protects the injector tip from being damaged while advancing the injector tip to a target injection site.
