20080286206Composition and Method for Medical Imaging of Body Cavities - The present invention relates to an image enhancing composition for the enhancement of contrast in a body cavity, wherein the viscosity of the composition is between 2000 and 4000 mPa·sec. It also relates to a method for enhancing contrast of an image of a body cavity, which method involves introducing one single small aliquot of an image enhancing composition into the body cavity. In another aspect, the present invention provides a high contrast image of a body cavity obtained by the method of the invention, in particular a 3-dimensional high contrast image.11-20-2008
20090062770SEALING STOPPER AND ASSEMBLY COMPRISING SUCH A SEALING STOPPER - In order to enlarge the uterus, inter alia for diagnostic purposes, it is proposed to seal the cervix once a liquid, such as a gel, has been introduced, by means of a sealing stopper, so that liquid does not constantly have to be supplied to the uterus. The sealing stopper is preferably coupled to a gel feed device which may comprise a simple syringe-type structure. This system comprises a non-return valve, as a result of which a gel can only be displaced in the direction of the uterus. In order to ensure that the sealing stopper can be removed, return means, such as a piece of string, are attached thereto.03-05-2009
