Embodiment 400

[0102] Embodiment 400 may utilize components of a urinary circulator described in U.S. Patent Application S.N. 10 / 010,534, filed December 7, 2001, the disclosure of which is incorporated herein by reference, and embodiment 400 may include a chamfered inlet connector 402 and the chamfered outlet connector 404 connected to the opposite end of the non-magnetic main housing 420, the latter may have a male protruding end 424 that clicks into and sealingly connects to a female protruding end 422 within. A vent port 426 may be located on the downstream end of the male housing portion 424 . Secured within the upstream portion 422 of the housing 420 is a valve member 432 formed of a magnetic member and the like and fixedly positioned adjacent a hollow valve port ring 434 whose central flow passage may be formed with a resilient valve seat 436. The movable valve member 438 is opened and closed, and the valve member can move back and forth along the inner channel track 439 in the direct...

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 than 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.
