Medical devices and compositions for delivering anti-proliferatives to anatomical sites at risk for restenosis

摘要

Methods, compositions and devices for inhibiting restenosis are provided. Specifically, molecular chaperone inhibitor compositions and medical devices useful for the site specific delivery of molecular chaperones are disclosed. In one embodiment the medical device is a vascular stent coated with a molecular chaperone inhibitor selected from the group consisting of geldanamycin, herbimycin, macbecin and derivatives and analogues thereof. In another embodiment an injection catheter for delivery an anti-restenotic effective amount of geldanamycin to the adventitia is provided.
