The Potts-Cournand Needle with Obturator and Cannula Extenderis a three-part single-use needle designed for optimum angiography procedures.
The inner cannula'sneedle point has an arterial bevel and is precisely fitted with the outer cannula that facilitate an accurate and efficient penetration. The rounded blunt obturator hemispherical top also assists in threading into the vessel.
The outer needlewith cannula is built with a short bevel tip, which, with the lightweight plastic hub, ensures a safepercutaneous entry with minimum trauma. The slightly protruding cannula also helps to avoid coagulation within the device. The hubs are made non-radiopaque plastic that, coupled with the winged handle, maximizes comfort.
