  • Patent number: 12239824
    Abstract: A needle-free injector includes a housing, a cartridge positioned within the housing, and a plunger slidably coupled to and disposed within the chamber, a motor operatively coupled to the plunger, the motor operable to actuate the plunger in the chamber, and a controller operatively coupled to the motor. The controller is operable to selectively operate the plunger according to any of a first delivery profile, a second delivery profile, and a third delivery profile. The controller may transition from the first delivery profile to the second delivery profile responsive to compression of a gas in the chamber, e.g., upon detecting a spike in a measured current applied to the motor. The controller may transition from the second delivery profile to the third delivery profile responsive to detecting a steady state condition between the measured current and a velocity of the plunger. Methods of delivering an injectate using the needle-free injectors are provided.

  • Patent number: 12115353
    Abstract: An apparatus for injectate delivery includes a cartridge, a linear actuator, a rotary motor mechanically coupled the actuator, and a controller coupled to the motor. The controller controls a linear motion of the actuator by controlling an electrical input supplied to the motor in a first interval during which the motor is stationary with the linear actuator engaged with the cartridge to displace an injectate in the cartridge, a second interval following the first interval during which the controller accelerates the motor from stationary to a first speed selected to create a jet of the injectate from the cartridge with a velocity sufficient to pierce human tissue to a subcutaneous depth, a third interval during which the controller maintains the motor at or above the first speed, and a fourth interval during which the controller decelerates the motor to a second speed to deliver the injectate at the subcutaneous depth.

  • Patent number: 11980743
    Abstract: An apparatus for use in injectate delivery includes an actuator including a linkage, a force generating mechanism mechanically coupled to the linkage, and a controller coupled to the force generating mechanism. The force generating mechanism includes a passive force generator and an active force generator. In operation and on the basis of a control signal, the controller is configured to control the force generating mechanism to provide an input force to the linkage that is a combination of the first force provided by the passive force generator and a second force provided by the active force generator.

  • Patent number: 11344677
    Abstract: An injection guide globally aligns an injector to an angle selected for consistent subcutaneous delivery of an injectate, while locally aligning a patient's skin normal to the injection path at the location where the injection pierces the skin. This arrangement advantageously maintains controlled contact between an injector and a subject's skin in order to deliver the full, intended volume of injectate into the patient's subcutaneous layer while avoiding misdelivery into adjacent layers such as the patient's dermis or muscle.
