The Seldinger Somatex soft drainage set is ideal for the treatment of localizations that are deep lying and difficult to reach. It allows for percutaneous drainage using the guide wire technique. The drainage catheters are made from soft polyurethane and the high barium sulphate content gives good x-ray contrast. The surface of the catheter is smooth, and the large oval eyes on the side allow for the best possible drainage. This set comes with a secretion bag, three-way valve, attachment tape, dilators, guide wire, puncture cannula, obturator for catheter stretching, and a pigtail drainage catheter with oval side eyes.
