Teleflex Incorporated announced that the ARROW UltraQuik peripheral nerve block (PNB) needles have received 510(k) clearance from the U.S. Food and Drug Administration (FDA). ARROW UltraQuik peripheral nerve block needles are designed to help increase overall block success for clinicians who use ultrasound-guidance when performing single-injection PNBs. UltraQuik needles maintain many of the same clinician-inspired features of the ARROW(R) StimuQuik(R) ECHO needles, including five grooved rings at the distal tip of the needle to help clinicians identify the needle tip under ultrasound.
