This perfect needle for percutaneus injection of alcohol is made to perfection. Percutaneous injection of ethanol (PEI) in liver tumours leads to necrosis of the neoplasia . The homogeneous diffusion of ethanol inside the tumour is fundamental in achieving a complete necrosis, where the wide side ports follow a spiral path on the cannula for enhanced and improved diffusion of the ethanol.Due to available size range, one may chose in three different forms. They are Gauge: (20-21-22G), centimeter length: (9-15-20 cm) and length of perforated tract: (4-12-20 mm). Capsulated tumours has a PIA® available with both, closed (PIA®-B) and open (PIA®-A) point. Such PIA® is provided with an inner obturator, which imparts stiffness to needle during penetration and allows the emptying of alcohol before withdrawing it. Few of its striking features are:- -It is provided with smooth sliding stopper which facilitates accurate depth placement. -It has a comfortable plate and needle to syringe connection. -For determination of needle size (gauge), it comes with a Colour code.
