When introduced to the world in 2009, SonoPlex STIM quickly become recognized as the standard against which all competing Single Shot nerve block needles would be compared. A pioneering embossed needle surface, CORNERSTONE REFLECTORS, provides clear and certain needle imagery under Ultrasound guidance, while the patented NANOLINE ultra-thin coating ensures the ultimate in smoothness of needle surface while eliminating the problem of increased needle diameter presented by conventional thick insulation coatings.

What has changed?
Small, but significant evolutions are found in SonoPlex STIM ll's needle hub alone: 

• DETACHABLE STIMULATION LEAD WIRE.
SonoPlex STIM ll may be placed under Stimulaton guidance or Ultrasound guidance or both. For those who wish to use Ultrasound guidance only, SonoPlex STIM ll's new hub design permits the lead wire to be detached - rather than cut - thus preserving the sterile field. 

• INTEGRATED NON-DETACHABLE  INJECTION TUBING
SonoPlex STIM ll's new hub design incorporates its injection tubing as a non-removable component of the needle, thus creating a closed system and so eliminating the possibility of leakage.

• COLOUR CODED NEEDLE HUB
For quick needle size (guage) identification.

What has not changed?

• CORNERSTONE REFLECTORS
The revolutionary embossed surface that permits Ultrasound reflection "In" or "Out-of-plane" and at any angle of needle placement, thus providing always a clear reflective Ultrasound image.

• NEEDLE TIP GRINDING IN 2 INCLINATION ANGLES
Where conventional needle tips are cut in a single bevel, SonoPlex STIM and SonoPlex STIM ll are cut and ground with 2 bevel angles for increased Ultrasound reflectivity at the tip.

• ULTRA-THIN NANOLINE INSULATION COATING
Ultra-thin and ultra-smooth, NanoLine provides absolute insulation while promoting a free-gliding needle to minimize insertion resistance. Further, NanoLine coating is applied on both the outer needle surface and the inner lumen of the needle - with only the tip left bare - thus providing the absolute in insulation performance and pin-point stimulation at the needle tip.
