Drug Delivery Implantables

Pharmaceutical and medical device companies are constantly exploring new ways to deliver drug molecules to patients. Through passive diffusion, we can control drug flow rates to achieve a therapeutic dosing window for six months or more using an implantable package. Our solutions are ideal for drugs that require frequent injection or dosage or can cause elevated plasma toxicity levels. They also offer manufacturers new drug delivery options to provide a competitive advantage in the marketplace. Mott can also conduct drug diffusion feasibility studies to help guide the design criteria for your next-generation, controlled-release drug delivery product.

    Controlled-Release Drug Diffusion Tech Brief

    Mott's controlled-release drug diffusion studies reduce in vitro test time by more than 90%.

    Product Specs

    Drug Flow Rates

    We can customize passive diffusion membranes in a range of porosities and dimensions to meet drug delivery flow rate requirements and concentration over time.  Therapeutic window can be maintained consistently for extended periods.

    Flow Accuracy

    Achieve consistent zero-order drug release for extended periods at tight dose standard deviation.

    Device Hardware

    Assemble your flow element into an array of hardware options.


    We employ biocompatible titanium and 316L stainless steel, which have been successfully proven for use in implanted devices.  As always, custom alloys and materials are available upon request.

    Our Design Capabilities

    • Customizable, ultra-small components used in implantable devices
    • Integrated device concept manufacturing for proof-of-concept trials or transition to production
    • Extensive partner network for new materials
