DELIVERY DEVICES AND MEHODS FOR HEART VALVE REPAIR

摘要

Devices, systems and methods facilitate positioning of a cardiac valve annul us treatment device, thus enhancing treatment of the annulus. Methods generally involve advancing an anchor delivery device through vasculature of the patie nt to a location in the heart for treating the valve annulus, contacting the anchor delivery device with a length of the valve annulus, delivering a plurality of coupled anchors from the anchor delivery device to secure the anchors to the annulus, and drawing the anchors together to circumferentiall y tighten the valve annulus. Devices generally include an elongate catheter having at least one tensioning member and at least one tensioning actuator f or deforming a distal portion of the catheter to help it conform to a valve annulus. The catheter device may be used to navigate a subannular space belo w a mitral valve to facilitate positioning of an anchor delivery device.
