What Are Combination Devices?

A combination device is a medical product that combines multiple components regulated under different categories by regulatory bodies like the FDA. For instance:

• Drug-Device Combination: Inhalers delivering asthma medication.
• Device-Biologic Combination: Bioengineered skin grafts.
• Drug-Biologic Combination: Vaccines combined with adjuvants.

These devices are designed to enhance therapeutic outcomes by merging the strengths of individual components.
