Abstract
An applicator for insertion into a body opening for medical treatment or for diagnostic purposes comprises an elongated jacket for insertion into the body opening, a disposable sleeve received on the jacket, and a balloon integrally formed on the disposable sleeve at one side of the jacket. The balloon is inflatable by a fluid to press the opposite side of the jacket and sleeve laterally against the tissue of the body opening, thereby to fix the position of the jacket within the body opening and to conform the pressed body tissue to the shape of the opposite side of the jacket. The applicator further includes a microwave antenna disposed within the jacket, the jacket further including cooling ducts adjacent its outer surface for circulating a cooling fluid therethrough in order to prevent undue heating of the body tissue in direct contact with the jacket.
