These urodynamic catheters from Mediplus are used to move into the bladder and to be filled easily. It uses a body that is easy to fill in even if the filling lumen is larger than the one that measures pressure levels. About a third of the lumen cross-sectional spot works for measurements. The rest is used for filling. This uses a filling rate that runs at around 100 mL per minute on the Ch.8 and 10 sizes. The diameter is smaller than what is used elsewhere and is made with pressure adjustments to make it suitable. This is convenient and easy to manage in most spaces.
