Patent ID: 8777871

Claim:
A medical device for penetrating living being tissue, said device comprising: a penetrating member which is vibrated to reduce the force needed to penetrate living being tissue; a driving actuator coupled to said penetrating member and causing said vibration when energized; an electrical power cut off automatically de-energizing the driving actuator when said penetrating member has passed through the living being tissue; and a side port through which fluid pressure is monitored to initiate the automatic electrical power cut off, wherein fluid is introduced through the side port and into the penetrating member, wherein a longitudinal axis of the side port intersects a longitudinal axis of a bore and is oriented at a non-parallel angle at the intersection to the longitudinal axis of the bore, wherein the longitudinal axis of the bore is in turn oriented at a parallel angle to a longitudinal axis of the penetrating member; wherein the driving actuator has a horn that has a displaceable body that is displaced when the driving actuator is energized, wherein the bore is located in the displaceable body, and wherein the side port is located in the displaceable body.
