Patent ID: 8226680

Claim:
A system for embolizing a target site in a vasculature of a body, comprising: a vaso-occlusive device detachably coupled to a distal end of a delivery wire insertable through a delivery catheter for deploying the vaso-occlusive device at a target site in a vasculature of a body, wherein the vaso-occlusive device is coated with a therapeutic bioactive agent, and additionally having a polymeric material coating substantially covering the bioactive agent coating; and an external energy emitting device configured to deliver energy from a location outside the body to thereby heat the vaso-occlusive device after the vaso-occlusive device has been deployed at the target site in the body, wherein, when heated by energy emitted from the external energy emitting device, the polymeric material coating at least partially melts or softens so that the bioactive agent is released or activated at the target site.
