  • Device for effecting radiation therapy in an animal body
    Patent number: 7252629
    Abstract: A device for effecting radiation therapy in an animal body has a housing provided with at least one outlet channel, a guide tube connected at one end with the outlet channel and wherein the other end of the guide tube is positionable in the animal body near the site of the intended radiation therapy, one electro-magnetic radiation emitting source connected to a first end of a transport wire, and a transport device for moving the transport wire and the radiation emitting source via the outlet channel through the guide tube to and from the site of the intended radiation therapy in the body. The transport device has a rotatable drum, which is rotationally symmetric around a rotation axis. The drum is provided with two end surfaces, and a circumferential surface is provided with at least one winding groove for at least one transport wire.
