The Enable device allows patients to comfortably self-administer high-volume and/or high-viscosity therapeutics. The selected materials needed to meet a variety of requirements for patient safety, including durability and biocompability while offering good aesthetics.


Covestro supported Enable Injections every step of the way from material selection to in-house part testing and manufacturing support. The housing of the on-body device features Makrolon®Rx1805 polycarbonate in a purple tint. Bayblend® M850 XF polycarbonate/acrylonitrile butadiene styrene (PC+ABS) blend in a white tint is featured on the transfer system, which allows the patient to easily transfer the biologic drug from its original container to the Enable on-body delivery device.
