Abstract:

The invention is an implantable medical device to expand a vascular lumen into various positions, internally or from a remote location. The device is designed as a stent having a framework for radial or longitudinal expansion, including one or more integrated shape memory materials. The shape memory materials, or halos, radially expand to fix the framework into a first radial position. Sensors integrated with the framework mechanically or electro-mechanically monitor and control the positioning of the framework to a fixed second position, or gradually expand the framework to various radial positions. Visualization and communications devices assist in the monitoring and controlling mechanisms to position the implantable device during surgery or catherization, post-surgery, or at follow-up. The device is biocompatible, alleviating complications. The device can be utilized as a substitute, or in combination with another stent. Devices may be utilized in cardiovascular, neurovascular surgery or other intervention.
