Abstract

Devices and methods for cutting a tether are described herein. Devices described herein generally comprise a proximal handle, a catheter, and an inner shaft and a cutting blade disposed within the lumen of the catheter, where the cutting blade is movably disposed over the inner shaft. The proximal handle comprises an actuation mechanism to control the movement of the components of the device. Methods described herein generally comprise advancing a tether-cutting device over a tether, loading the tether through the catheter and inner shaft, applying tension to the tether, and rotating and distally translating a cutting blade in order to cut the tether.
