Drug eluting stent and a guide catheter device assembly for implanting the same

摘要

The present invention relates to a drug eluting stent for delivering therapeutic agents to a body lumen. The stent includes an expandable substrate configured for implantation in a vessel of a human body and a therapeutic agent composition coated over the stent. The balloon catheter shaft has a resilient unit that helps to transmit a force to the distal end, thereby helping to cross lesions.
