Description of event according to initial reporter: the device was introduced via the right jugular vein.The physician attempted to release the filter but the sheath would not be withdrawn properly so the filter hook was still covered.Since the filter was placed in the correct position and legs gripped on the vessel wall, it was released by pushing the metal button.After removal of the delivery system, the sheath was able to be withdrawn but the grasping hook was not present at the tip of the catheter.Additional information received 09oct2013: the grasping hook was not identified under fluoroscopic guidance.Patient outcome: the patient did not experience any adverse effects due to this occurrence.
