Patent ID: 11123461

Abstract:
A method and device for localized treatment of tissues or organs that were exposed to ischemia and reperfusion (IR) injury, in order to reduce their structural damage and loss of function. The method further includes intra-arterial treatment of transplanted tissues or organs, which are exposed to similar damage of IR and are at risk of impaired function. Leptin antagonist is administered as a bolus injection directly into a re-opened artery, which supplies blood to the tissue or organ involved, immediately after reperfusion. In some cases, after administering a bolus injection of leptin antagonist, the effect of leptin antagonist in the involved organ can be prolonged by deploying a double function drug eluting stent, which elutes leptin antagonist into the lumen, e.g., by sustained release, while eluting antiproliferative drug into the vessel wall to prevent local stenosis, which may appear due to stent deployment.
