Abstract: An aqueous gel composition comprising a) water, at least one polysaccharide and at least one high molecular weight polyethylene oxide, wherein the water content is at least 90% by weight of the composition, and b) a local anaesthetic agent or an analgesic agent, for use as a local anaesthetic or analgesic. The aqueous gel shows transparency, lubricity, stringiness, elongation, extensiveness, and cohesiveness while being devoid of taste and smell and non-tacky or non-sticky.

Abstract: An endoscopic puncture needle device comprising: an elastic catheter introducible into an instrument channel of an endoscope; a flexible hollow puncture needle extending through the catheter; a cylindrical handle casing extending in the longitudinal direction of the hollow puncture needle, the proximal end of the catheter being connected to the distal end of the casing; and a hollow rod connected to the proximal end of the hollow puncture needle, for reciprocating the hollow puncture needle within the catheter, said hollow rod being mounted in the handle casing coaxially with the proximal end of the catheter and displaceably in the longitudinal direction. In order to allow for easy and precise adjustment of the puncture depth of the hollow needle arranged in the catheter of the puncture needle device, the distal end portion of the handle casing is provided with a thread which can be screwed to a threaded hollow pipe socket arranged at the entry of the instrument channel of the endoscope.
