Abstract

The present invention provides devices, systems and methods for tissue access and repair at a treatment site. The devices, systems and methods of the present invention will be suitable for use in a variety of therapeutic procedures including endovascular, minimally invasive and open surgical procedures, and may Used in various anatomical regions of bladder, lungs and other organs, blood vessels and tissues. The present invention is particularly useful for those procedures requiring minimally invasive or intravascular access to distal tissue sites, where the instruments utilized must travel along long, narrow and tortuous paths to reach the treatment site. Additionally, many of the devices and systems of the present invention can be reversible and removed from the patient at any point without interfering with or damaging the internal tissue.

Description

technical field 1. Field of the invention

[0001] The present invention generally relates to medical methods, devices and systems. In particular, the present invention relates to methods, devices and systems for endovascular, percutaneous or minimally invasive surgical treatment of body tissue, such as tissue approximation or valve repair. More specifically, the present invention relates to valvular repair of heart valves and venous valves. Background technique

[0002] Mitral regurgitation is characterized by retrograde flow from the left ventricle of the heart through the incompetent mitral valve into the left atrium. During the normal cycle of heart contraction (systole), the mitral valve acts as a check valve to prevent oxygenated blood from flowing back into the left atrium. In this way, oxygenated blood is pumped through the aortic valve into the aorta. Valve regurgitation can significantly reduce the heart's pumping efficiency, putting patients at risk for severe,...
