RECTAL BALLOON PROBE FOR PROTECTING THE RECTAL WALL DURING RADIOTHERAPY

摘要

Probe, for example for protection of the rectal and anal wall tissues during radiotherapy, for example an insertable intracavity probe, for example to be used during radiotherapy of a prostate gland, wherein the probe at least includes a shaft having a closed distal tip, wherein the shaft is provided with an inflatable device, for example a balloon and/or a elastic membrane, wherein the inflatable device substantially abuts an outer surface of the shaft when the inflatable device is in a deflated position. The invention also provides a system for planning and delivering radiation therapy treatment of an internal organ of a patient by a radiation emitting device, comprising a radiation emitting device; and a probe according to the invention to be inserted within a cavity of a patient during delivery of a dose from the radiation emitting device.
