Congruence Medical Solutions LLC

The Congruence Autoinjector is a next generation disposable autoinjector platform,  capable of delivering high-dose drugs and suitable for home use (self-injection).

It leverages a compressed-gas power source and proprietary usability features to offer several advantages over legacy devices, including the ability to deliver higher viscosity and/or larger volume drugs, enhanced usability and easier customization – all in a compact format while incorporating standard primary containers. 

The Congruence Autoinjector’s novel usability features, such as Injection Pause™ Technology, mitigate well-known autoinjector user errors, such as premature removal from the skin prior to dose completion.

Congruence Injection Pause™ Technology and novel Visual Dose Progress Indicator
address premature removal from skin, increasing potential for full dose delivery


The Congruence Autoinjector is intended to enable drug delivery by a patient or caregiver in a home or other non-clinical setting. 

The platform’s ability to deliver viscous drugs in a compact format means it is particularly suited to delivering high-dose (concentrated) biologic formulations found in oncology, autoimmune disorders, and other areas.

The platform is highly versatile and therefore also suitable for a wide range of drugs beyond just high-dose formulations. It’s versatility also enables use by Biopharma and Biotech customers across the drug lifecycle (including during drug development) and/or across multiple drugs in a portfolio.



The Congruence Autoinjector platform is designed with versatility in mind. The use of an alternative (non-spring) power source means that it can be readily customized to accommodate a wide variety of specific drug viscosities (100cP+), injection volumes (up to 5mL), target injection times and preferred needle gauges.

The autoinjector accommodates a choice of various ISO 11040 compliant standard glass syringes of size 1mL long, 2.25mL or 5mL. Use of a cartridge is possible for larger volumes. External Look and Feel can also be customized.
