Abstract: A needle knife device and system for cutting soft tissue under skin of a patient are provided. The needle knife can include an elongated needle including a lumen and a beveled point configured to allow the elongated needle to be inserted transcutaneously into the skin of the patient. The needle knife can also include a blade that is capable of being oscillated within the lumen of the elongated needle between a retracted position where the blade is disposed within the needle and a deployed position where the blade is disposed outside the needle beyond the beveled point. A motor unit can be operatively arranged with the blade and configured to oscillate the blade.

Abstract: The NEEDLE KNIFE APPARATUSES, METHODS AND SYSTEMS (“NK”) may have a cannula, through which a needle knife may be deployed. The needle knife may oscillate to cut through a patient's tissue, such as muscle tissue in the forehead of a patient to eliminate forehead wrinkles. In certain embodiments, the knife portion of the needle knife is normally sheathed within a cannula during insertion into and removal from a patient. The oscillation may be performed manually or by a motor, which may be attached via a connection mechanism. The connection mechanism may include a colley system or be glued in place. Once inserted into a patient, the oscillating motor mechanism is engaged to rapidly oscillate the needle knife to expose the knife to rapidly cut soft tissue.
