An apparatus for and method of recirculating fluid used in performing hysteroscopic endometrial ablation. The fluid preferably circulates through a closed loop, fluid delivery system (10), including a heater (24) for heating the fluid, and passes through a chamber (12) of known volume having graduated markings disposed thereon so that the amount of fluid circulating within the closed loop system can be continuously monitored. The apparatus is connected to the inlet (8) and outlet (9) ports of a hysteroscopic sheath (7) positioned within the uterine cavity of a patient. Any drop of fluid level within the marked chamber (12) will indicate to the surgeon that the patient is undesirably absorbing fluid so that the procedure may be swiftly terminated before adverse consequences occur.
Dispositif et procédé de recirculation d'un liquide qu'on utilise dans l'ablation de l'endomètre par hystéroscopie. Le liquide circule, de préférence, à travers un système d'alimentation en circuit fermé (10) comprenant un ensemble de réchauffement (24) du liquide et traverse une chambre (12) à volume déterminé, sur laquelle se trouvent des marques graduées, de manière à pouvoir contrôler en continu la quantité de liquide circulant à l'intérieur du circuit fermé. Le dispositif est accouplé à l'entrée (8) et à la sortie (9) d'une gaine hystéroscopique (7) placée à l'intérieur de la cavité utérine de la patiente. Toute baisse du niveau du liquide à l'intérieur de la chambre (12) indiquera au chirurgien que la patiente absorbe anormalement du liquide, ce qui permet de mettre fin à l'intervention rapidement avant l'apparition d'effets secondaires indésirables.
