Automated Drug Microinjection Device with Spring-Loaded Microneedle and Shape Memory Locking Member
Summary
USPTO published patent application US20260097194A1 for an automated drug microinjection device featuring a spring-loaded microneedle with shape memory locking member, pump cavity with actuator, and motor-driven gear assembly for controlled drug delivery. The device enables precise microinjection through a locked-and-retracted microneedle released by a signal. Filing date was October 8, 2025.
What changed
USPTO published application US20260097194A1 claiming an automated drug microinjection device and operating method. The device integrates a container, spring-loaded microneedle with shape memory locking member, pump with cavity and actuator, motor, controller, and gear assembly. The microneedle is spring-biased to extended position and retained in locked retracted position until release signal activation.
Medical device manufacturers and pharmaceutical companies developing drug delivery systems should review the claimed technical features, particularly the spring-loaded microneedle mechanism combined with shape memory alloy locking, which represents a novel approach to controlled microinjection. The motor-driven pump actuator with integrated gears enables precise dosing through the microneedle assembly.
What to do next
- Monitor patent prosecution status for allowance or rejection
- Review device specifications for potential licensing or design-around opportunities
- Assess freedom-to-operate relative to microneedle and pump actuator design

Abstract
An automated drug microinjection device for administering a controlled amount of drug, and a method of operating the device is provided. The device comprises a container storing the drug, a microneedle assembly, a pump, a motor, and a controller. The microneedle assembly comprises a spring-loaded microneedle and a shape memory locking member. The spring-loaded microneedle is biased to be in an extended position and the shape memory locking member is configured to retain the microneedle in a locked and retracted position until a release signal is applied. The pump comprises a pump cavity and a pump actuator. The pump actuator is operable to fill the pump cavity with drug from the container and dispense the controlled amount of the drug from the pump cavity through the microneedle. The motor is configured to drive the pump actuator through a gear assembly comprising one or more gears integrated into the pump actuator.
