Catheter assembly with guard

This medical catheter delivers drugs inside the body using an inflatable balloon-like structure. A protective guard bonded to the balloon creates tiny pockets, or reservoirs, that hold a drug coating. When the balloon expands, the drug coating protrudes from these pockets to release medication directly where it's needed.

Why it matters: Since 2011, advancements in micro-fabrication and biocompatible drug coatings have made precise, localized drug delivery more feasible. This could enhance the controlled release from the catheter's guarded reservoirs.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedBiocompatible materials, precision bonding, drug coating.
