Estimating the term…
The present disclosure concerns microneedles around the exterior surface of a radially expandable medical device that puncture or pierce the vessel wall as the device expands. The microneedles can be embedded and/or coated with one or more therapeutic agents in order to provide localized delivery to the tissue where the medical device is deployed. In further aspects, the microneedles can be of a metal or a biopolymer that is degraded and/or absorbed within a subject. In some aspects, the microneedles may project from an underlying balloon. A protective covering is also contemplated for maneuvering the device within a subject.
A medical device comprising a radially-expandable scaffold structure with at least one microneedle positioned circumferentially thereon, wherein the microneedle comprises a coating layer on at least a portion of an outer surface, wherein the coating layer comprises at least one therapeutic agent.
