1. A method of manipulating tissue comprising:
navigating an endoscope to a target location;
advancing a device having a grasper at a distal end thereof through a working channel of the endoscope;
using a handle at proximal end of the device to engage tissue with the grasper, the handle comprising an inner collet and an outer sleeve that tightens the collet around the device;
locking the grasper using the handle such that the grasper remains engaged with the tissue, then;
detaching the handle from the device while the grasper remains engaged with the tissue;
retracting the endoscope over the device while leaving the device in place; and
reattaching the handle to the device, then;
unlocking the grasper using the handle such that the grasper disengages the tissue; and
removing the device from the target location.
