ACTIVATABLE BIOACTIVE IMPLANTABLE MEDICAL DEVICE AND APPLICATION METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide an activatable bioactive implantable medical device and a method therefor.

SOLUTION: The medical device such as a vascular occlusive device includes a support structure, a bioactive expansible coating film disposed on the support structure, and an outer barrier coating film which serves to prevent a reaction between the bioactive expansible coating film and bodily fluids until the outer barrier is activated and removed by supplying an external agent to the outer barrier thereby permitting expansion of the bioactive coating film.
