RADIATION EMITTING FLOW-THROUGH TEMPORARY STENT.

摘要

The invention is directed to an intravascular catheter with expandable region suitable for maintaining patency of a body lumen for a period of time sufficient to permit delivery of a radiation source to the body lumen. The expandable region centers the radiation dose within the body lumen, such as a coronary artery, and permits blood flow through the expandable region while radiation therapy is provided.
