Drug-releasing stent with ceramic-containing layer

A vascular or endoluminal stent is adapted to be implanted in a vessel, duct or tract of a human body to maintain an open lumen at the site of the implant. The sidewall of the open-ended tubular structure of the stent is a base layer of a metal biologically compatible with blood and tissue of the human body. An intermediate metal particle layer of substantial greater radiopacity overlies the base layer, with particles bonded to the base layer and to each other to leave interstices therebetween as a repository for retaining and dispensing drugs or other agents for time release therefrom after the stent is implanted, to assist the stent in maintaining the lumen open. The particles are composed primarily of a noble metal—an alloy of platinum-iridium. The sidewall has holes extending therethrough, and the particle layer resides along the outward facing and inward facing surfaces, and the edges of the through holes and open ends of the sidewall. The larger particles are bonded to surfaces of the sidewall and progressively smaller particles are bonded to those and to each other up to the outer portion of the particle layer. Exposed surfaces of the particle layer are coated with ceramic-like iridium oxide or titanium nitrate, as a biocompatible material to inhibit irritation of tissue at the inner lining of the vessel when the stent is implanted. One or more anti-thrombotic, anti-platelet, anti-inflammatory and / or anti-proliferative drugs are retained in the interstices, together with a biodegradable carrier for time release therefrom. In an alternative embodiment, the intermediate layer is solid and the biodegradable carrier and drugs or agents therein are applied to the surface of the ceramic-like coating. Gene transfer is alternatively used to control tissue proliferation.

Method of producing personalized biomimetic drug-eluting coronary stents by 3d-printing

A method for using 3D printing technology produces personalized biomimetic drug-eluting coronary stent and the product thereof. The process of manufacturing stent, based on coronary angiography imaging data, measures the diameter of diseased coronary and conducts 3D reconstruction. A personalized stent for each patient according to diameter, length, and morphological characteristics of target vessel that suited to the lesion is produced. The coronary stent is formed from biodegradable poly-L-lactic acid (PLLA) or other materials. The stent is modeled by 3D printing and then coated with polymers carrying antiproliferative drug to reduce restenosis (the polymers is a mixture of antiproliferative drug and PDLLA at a ratio of 1:1). The biomimetic drug-eluting coronary stent produced by 3D printing technology is personalized stent for each patient according to different characteristics of diseased coronary, reduces the incidence of vascular injury, thrombosis, dissection and other complications caused by stent and vessel diameter mismatch.

Devices and methods for reducing scar tissue formation

Disclosed is a cytostatic drug attached to a sterile sheet that is designed to be placed between internal body tissues to prevent the formation of post-operative adhesions, which adhesions are really scar tissue formation. This sheet onto or into which the drug is placed may be either a permanent implant or it may be biodegradable. By impregnating an existing product such as the Johnson & Johnson SURGICEL™ absorbable hemostat gauze-like sheet with an anti-proliferative drug such as sirolimus, the biodegradable, drug impregnated mesh would act as a barrier to cell proliferation and hence be a deterrent to the formation of adhesions or scar tissue. Another embodiment of this invention is a cytostatic drug attached to a sheet that is placed at the site of an anastamosis to decrease scar tissue formation from within the vessel at the site of the anastomosis.

Treatment of ischemia and reperfusion using leptin antagonist

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.
