Vasco-occlusive devices with bioactive elements

摘要

Vaso-occlusive devices for occluding a body cavity include an internal element located within a lumen of the device. The internal element may comprise or otherwise include an agent carrier that comprises a bioactive material capable of eliciting a biological reaction after the device is placed in-situ. For example, the bioactive material can be a part of a composition of the agent carrier, absorbed by the agent carrier, or coated as a layer on the agent carrier.
