Drug Eluting Devices
Biomedical grade silicones for drug eluting devices
Medical grade silicone for drug eluting devices
The growth of drug eluting devices is tied to several key advantages including targeting drug delivery to specific locations (lowering systemic toxicity and minimizing drug dosage) and eliminating reliance on patient compliance (through sustained release over a given time).
Biomedical grade silicones are a great choice for drug eluting devices because silicones form a permeable matrix structure when cured, creating space for API to reside and consistently pass through over time. Silicones have also been used in implantable devices for more than 60 years.
Common Examples of Drug Eluting Devices
- Coronary and peripheral vascular stents to reduce or prevent scar tissue formation
- Women’s Health (IUD, IVR and subcutaneous implants) for contraception, HIV prevention, or hormone replacement therapies
- Ophthalmic Devices (punctum plugs and lenses) to address dry eye or to deliver therapies to the retina
- Catheters and leads as part of larger devices to provide antimicrobial and anti-inflammatory benefits
- Pain Management
- Oncology applications for the treatment of brain tumors, prostate cancer, and bladder cancer
In addition to a comprehensive series of Silbione™ Biomedical M series Liquid Silicone Rubber (LSR) and High Consistency Rubber (HCR), which support the long-term implantable device applications, Elkem offers the Silbione™ Biomedical LSR D series that supports the drug delivery applications.
