## Indications for use
The BRAVOS Afterloader System is intended for use in the treatment of both benign and malignant disease or other conditions, for both curative and palliative intent, in the delivery of remote-controlled High Dose Rate (HDR) brachytherapy. The Transfer Guide Tubes are intended to connect between the BRAVOS Remote Afterloader system and its range of Applicators. This connection creates a conduit for the source cable to travel through and allows the radioactive isotopes to be positioned within the patient´s tumor site. The Length Assessment Device is intended to allow the user to establish an approximate length of an unknown length channel prior to the afterloader performing definitive length verification.
