Abstract:
Medical device with drug delivery technology has improved over the last 20 years to address issues with ease of application or implantation, biocompatibility, durability, bioabsorbability and drug dosage control. These developments have been applied to stents and lenses, heart valves and seats, vascular stents and shunts, hemostasis and embolization, post-surgical closure, liquid bandages, and other areas. The devices have also been used as drug delivery vehicles. New technologies must be tailored to the target physiologic environment since materials that function well in one environment may fail in another. Research has brought about a much greater understanding of the importance of the surfaces of medical devices in terms of the reaction to contact with bodily fluids and tissues, and novel materials have been developed that resist attachment to cells, platelets, calcium deposits, etc. Overall, greater understanding of the specific environment in which a device will be deployed leads to more reliable, durable and functional designs with fewer complications over time. This talk will explore some of the advancements in polymer chemistry and hydrogel-based materials and how these technologies have been applied to medical devices and drug delivery in numerous settings. Significant challenges remain in the medical device and delivery arena, and potential future advancements will be discussed.
