ABSTRACT:
Indwelling catheter having an upper distal end having a portion that can expand within a bladder type spaces without having to be inflated. An embodiment allows for at least one slit on an upper side of the catheter tube and a head member that when pulled down by a stylette moving inside the catheter causes a bulge wing portion(s) that holds the catheter safely and painlessly within the bladder. Magnetic and electret valves can be included inside the tube of the catheter that can cycle between open and closed positions when activated by normal bladder pressure when urination is desired. The novel catheter tube can naturally conform to an opening and closing urethra during natural bladder drainage. The catheter tube surface can include an anti-microbial layer that is either or both coated and impregnated thereon with either an antibacterial and/or hydrophyllic materials. Sampling ports can be located on both inside catheter tube valves and on an externally attached magnetic valve.
