Magnetic cycler valve for catheters

摘要

Indwelling catheter having an upper distal end having a portion that can expand within a bladder type spaces without having to be inflated as dislcosed. Magnetic valves (436) can be included inside the tube (420) of the catheter that can cycle between open and closed positions when activated by normal bladder pressure when urination is desired. The catheter tube can naturally conform to an opening and closing urethra during natural bladder drainage. Sampling ports (410) can be located on both inside catheter tube valves and on an externally attached magnetic valve.
