The set consists of a long needle (16G), a guide wire, a trocar with an outer sheath and a choice of 8, 12, 14 or 16 Fr silicone catheters. The catheters are available in either open tip or closed tip. (8 and 12Fr are only available in closed tip)
The anaesthetised tract is created in the normal way, but the needle is left in the patient. The guide wire is then inserted through the needle into the bladder. It will curl upon the posterior wall preventing the trocar from being pushed in too far. The needle can then be removed. The trocar is then inserted in a controlled manner, helping to reduce user anxiety and ensuring it enters the bladder.
