Abstract
This is a medical device for forming an embolism within the vasculature of a patient. More particularly, it is a vaso-occlusion device at least partially coated with a bioactive agent, a collagenous material, or a collagenous coating optionally containing or coated with other bioactive agents. A coated vaso-occlusive device which is highly flexible is also a variation.
Claims42
A vaso-occlusive device comprising:
- a) a vaso-occlusive member;
- b) an adhesive inner coating on at least a portion of said vaso-occlusive member;
- and
- c) a protein-based outer coating on said inner coating.
