Drug Delivery Implantables

Pharmaceutical and medical device companies are constantly exploring new ways to deliver drug molecules to patients. An exciting frontier in drug delivery technology is in the field of implantable drug delivery devices.

Surgically implanted devices already serve a wide variety of functions in modern medicine, from titanium replacements for failed joints to electronic devices that help the human heart maintain its rhythm. Using medical implants in the administration of drugs offers doctors and researchers the ability to monitor and control dosages more closely than ever before. In addition to this, they are able to more effectively localize drug deployment to a specific area of the body. Both of these innovations can lead to improved patient outcomes and better data.

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.


Whether you are just beginning to explore the feasibility of drug delivery flow elements and implant-based disbursement for a new drug product or your project is already well into the design phase, bringing our experienced team on board can help overcome any design obstacles. Additionally, we ensure the viability of your product, analyze your processes, and collect the data you need to move forward with production or make changes so your pharmaceutical drug delivery devices are successful.

    Literature & Data Sheets

    Typical Applications

    • Low-Flow Drug Delivery. Implant-based drug disbursement allows for extremely low-flow drug delivery whereby low doses can be released into a patient’s bloodstream on a tightly controlled timeline.
    • Implantable Sustained Release. Medical implants can release a slow, steady dose of medication more consistently than extended-release oral pills. This allows doctors to better control drug diffusion throughout a patient’s body.
    • Catheter-Based Release. Recent studies have shown promise in using catheter-based treatments to deliver cells directly to the heart, for example.
    • Overdose Protection. Using implants to tightly control the release of medication into the bloodstream makes overdose extremely unlikely.

    Low-Flow Drug Delivery

    Mott can customize delivery devices to meet specific requirements to manage extremely low flows for the release of therapeutic agents to optimize patient outcomes.
