1. A tissue grasping device for use through an endoscope, comprising:
a sheath defining a sheath lumen;
a control wire slidably disposed within the sheath lumen;
a tubular connector fixed to a distal portion of the control wire; and
a helical coil disposed over and fixed to the tubular connector such that the tubular connector is between an outer surface of the control wire and an inner surface of the helical coil, the helical coil including a proximal region in which adjacent windings are in contact, wherein the helical coil is slidable relative to the sheath from an undeployed configuration in which an entirety of the helical coil is disposed completely within the sheath to a deployed configuration in which at least a distal portion of the helical coil extends distally beyond a distal end of the sheath; and
a distal region in which adjacent windings are spaced apart, the helical coil having a sharpened distal tip.
