Publication number: 20230173184Abstract: An auto-injector includes a drive assembly within a housing carrying a syringe including a needle adjacent an activation cap within the housing's distal end. The drive assembly includes a first chamber carrying a gas canister, a plunger within a second chamber coupled to the syringe, and proximal and distal chambers. The activation cap is pressed against a subject's skin to direct the drive assembly proximally to open an outlet of the canister to release pressurized gas into the first chamber, whereupon the gas enters the proximal chamber to generate a distal force to advance the drive assembly to direct the needle into the subject and enters the second chamber to advance the plunger to deliver agents from the syringe into the subject. After the plunger advances, the gas enters the distal chamber to generate a proximal force to retract the drive assembly to direct the needle back into the housing.Type: ApplicationFiled: December 6, 2022Publication date: June 8, 2023Inventors: Matthew McCawley, Jack R.

Publication number: 20230119081Abstract: An injection device for delivering an agent into a patient’s body including a drive module and an injector module. The drive module includes a canister and puncture mechanism in a first chamber, a plunger in a second chamber communicating with the first chamber, and an actuator that moves the puncture mechanism to cause a puncture pin thereon to penetrate a septum of the canister and cause the gas within the canister to flow through the first chamber into the second chamber. The plunger includes a proximal end including a piston and a distal end and is configured such that gas entering the second chamber causes the plunger to move from an initial position to an extended position for delivering one or more agents from the injector module, the piston including one or more passages that allow gas from the canister to pass through the piston into the second chamber around the plunger.Type: ApplicationFiled: October 13, 2022Publication date: April 20, 2023Inventors: Matthew McCawley, Jack R.

Publication number: 20230014573Abstract: Devices and methods are provided for delivering gas. In one example, the device includes a syringe body including a proximal end, a distal end including an outlet and a gas chamber communicating with the outlet, and a plunger carrying a piston slidably received within the syringe body. A canister containing a gas is provided within the plunger adjacent a passage through the piston communicating with the gas chamber. A drive actuator is movable to cause an opener pin to open a septum of the canister and release the gas, whereupon the gas travels through the passage into the gas chamber, thereby displacing the piston proximally to fill the gas chamber. Once activated, the plunger may be advanced to deliver the gas within the gas chamber through the outlet into a patient's body, e.g., into an eye via a cannula connected to the outlet.Type: ApplicationFiled: July 12, 2022Publication date: January 19, 2023Inventors: Quinton A.

Publication number: 20220257863Abstract: Syringe drivers and injector devices are provided. The driver includes a housing including a port communicating with a gas chamber therein and connectable to an external air source, and a cavity that receives a syringe containing an agent. A drive piston within the housing includes a first end disposed adjacent the gas chamber and a second end including a plunger connectable to the syringe. A damping mechanism is provided within that housing that is coupled to the drive piston that includes a damper piston within a damping fluid chamber such that, when the drive piston is advanced by gas delivered into the gas chamber from the external source to deliver the agent from the syringe, damping fluid within the damping fluid chamber flows through an orifice or valve from a first region to the second region, thereby limiting movement of the drive piston.Type: ApplicationFiled: February 12, 2022Publication date: August 18, 2022Inventors: Jack R.
