Embodiment Construction

[0054] The drug / drug combination and delivery device of the present invention can be used to effectively prevent and treat vascular diseases, in particular, can effectively prevent and treat vascular diseases caused by trauma. Various medical devices used in the treatment of vascular diseases may eventually induce further complications. For example, balloon angioplasty is a type of surgery used to increase arterial blood flow, and it is also the main treatment for coronary artery restenosis. However, as mentioned above, this operation usually causes a certain degree of damage to the blood vessel wall, which may aggravate the disease in the future. Although other surgeries and diseases can also cause similar injuries, the exemplary embodiments of the present invention will combine percutaneous coronary angioplasty and other similar arterial / venous surgeries (including the connection of arteries, veins, and other fluid delivery catheters). ) And the treatment of restenosis and r...

Abstract

The invention discloses a dual drug stent. Implantable medical devices may be utilized to locally delivery one or more drugs or therapeutic agents to treat a wide variety of conditions, including the treatment of the biological organism's reaction to the introduction of the implantable medical device. These therapeutic agents may be released under controlled and directional conditions so that the one or more therapeutic agents reach the correct target area, for example, the surrounding tissue and / or the bloodstream.

Description

Background technique [0001] 1. Technical Field [0002] The present invention relates to the local administration of therapeutic agents and / or combinations of therapeutic agents for the prevention and treatment of vascular diseases, and more specifically, to intracavitary medical devices for local delivery of therapeutic agents and / or combinations of therapeutic agents. [0003] 2. Discussion of related fields [0004] Many individuals suffer from circulatory diseases caused by the gradual blockage of blood vessels that perfuse the heart and other major organs. In these individuals, more severe blood vessel obstruction often leads to hypertension, ischemic injury, stroke or myocardial infarction. The main cause of ischemic heart disease is atherosclerotic disease, which restricts or obstructs coronary blood flow. Percutaneous transluminal coronary angioplasty is a medical procedure designed to increase arterial blood flow. Percutaneous transluminal coronary angioplasty is the mos...
