A suprapubic puncture set for the Seldinger technique with a 4 Fr (Ch) / 17.5 G first puncture, placing the INTEGRAL pure-silicone balloon catheter for suprapubic bladder drainage.
The INTEGRAL dilating balloon catheter at Ch 12 with a 5 ml balloon, a Lunderquist guidewire at 0.035 inch and 70 cm with its introducer, a puncture cannula at 17.5 G and 1.3 mm with an 18.5 cm needle, two fascial dilators at Ch 10 and Ch 14, and a catheter plug. The carton holds five sets.
Because the tract is opened in stages after it: a first puncture at Ch 4 and 17.5 G, then a two-stage dilation with the long tapered Ch 10 and Ch 14 tips. The cannula and the dilators read on the X-ray, so each step is checked.
