    摘要： A percutaneous system for bypassing a restriction in an artery of a mammal having an aorta includes providing a graft having a body portion with a first end, a second end and a lumen therebetween. First and second expandable stents are provided at the first and second ends of the graft, respectively. Apertures are formed in the artery, distal of the restriction, and in the aorta and the graft is inserted between the apertures. At least a portion of the first stent is inserted through the aperture in the artery and the stent is deployed to connect the first end of the graft within the artery. The second stent is positioned such that a first expandable portion is outside the aorta and a second expandable portion is within the aorta. The first and second expandable portions of the second stent are expanded to have outer diameters at least as large as the aperture in the aorta to anchor the first end of the graft in the aorta such that the lumen in the graft communicates with the aorta and the artery.

    摘要： A method and composition for inhibiting restenosis. The composition includes an adhesive or polymeric material having a radioactive component dispersed therethrough. A biologically compatible adhesive including a radioactive material is applied to a vessel region where inhibition of restenosis is desired in a preferred method. In one composition, the radioactive material is admixed with the adhesive. In another composition, the radioactive material is chemically bonded to a polymeric adhesive. The adhesive is preferably cured in place. The radioactive material has a preferred half life of less than six months. In one method, the application of adhesive is followed by stent placement, leaving radioactive adhesive extending beyond both stent ends. The application can include forcing adhesive from a double walled balloon having a porous outer wall.

    摘要： Embodiments of the present invention provide a method for treatment of nonvascular body lumen strictures such as benign prostatic hyperplasia (BPH), urethral strictures, ureteral strictures, prostate cancer, esophageal strictures, sinus strictures, biliary tract strictures, asthma and chronic obstructive pulmonary disease (COPD). The method involves delivering, preferably via drug coated balloon catheters, of anti-inflammatory and anti-proliferative drugs (rapamycin or paclitaxel and their analogues) and one or more additives.
