  • Diagnostic method for inflammatory conditions in the intestines
    Patent number: 6183416
    Abstract: Method for diagnosis of inflammatory conditions in the intestinal canal of humans, characterized in that NO is measured in the lumen of the intestines. The NO level obtained is then compared with the level obtained for healthy individuals or with the level obtained for the same individual at another occasion. An increased level compared to the normal levels in the intestines of the healthy population is an indication of an inflammatory condition in the intestine.

  • Method and device for use in the diagnosis of inflammatory states in the urogenital tract
    Patent number: 6149606
    Abstract: Device and method for collecting endogenous gaseous nitric oxide (NO), in the urogenital tract, for example in the urinary tract and in the uterus and oviducts. According to one embodiment, a NO permeable, liquid impermeable inflatable body (16) is positioned in the urethra (5) surrounded by the prostate gland (17), whereby an additional inflatable body (4) positioned in the bladder (2) serves to seal off the bladder from the urethra and helps in the positioning of the device. The present invention further relates to a method and a system for use in the diagnosis of inflammatory states in said organs.
