Abstract: A device for removing tissue by means of laparoscopy or thoracoscopy with an operating part and an optionally partially open hollow tube with a guide for operating a removing part. The removing part has the form of a zeppelin with one or more ribs. The removing part is provided on the upper side with longitudinal connecting elements. Further described is an application of such a device in a surgical treatment wherein, by use of the operating part, the removing part with the form of a zeppelin is opened out, the removed tissue is collected in the expanded bag of the removing part, and the removing part with tissue is pulled optionally at least partially into the open part of the hollow tube. The connecting elements of the removing part can then be brought together and snapped or zipped closed.

Abstract: The present invention relates to an oil-in-water emulsion, wherein the oil comprises an acid functional unsaturated polyester which acid functional unsaturated polyester comprises unsaturated dicarboxylic acid units, diol units, units of an emulsifier with HLB value of from 9 to 20 and further comprising chain extender units. The present invention further relates to a fibre mat comprising fibres and a binder comprising such acid functional unsaturated polyester.
