Patent ID: 8529427

Claim:
A device for administering brachytherapy to the tissue of a living patient, comprising: a cup of a material at least partially transparent to x-ray radiation and having a longitudinal cup axis; a lid for threaded engagement with the cup and including a peripheral threaded downwardly depending section having a free end; a source guide for receiving an x-ray source attached to and penetrating through the lid of the cup and extending along a source guide longitudinal axis that is coincident with the longitudinal cup axis; a catheter carrying an x-ray source slidable within the source guide in the cup; wherein the cup can be positioned in an open resection cavity so that the catheter can be manipulated axially within the source guide in the cup; a manipulator for moving the source guide so that the x-ray source can be moved to different positions within the cup during the brachytherapy treatment; and a skirt formed integrally with the lid and extending coaxially with the cup axis; said skirt formed as a downwardly depending annular wall member having a free lower end that terminates at substantially the same location as the peripheral threaded downwardly depending section free end of the lid; wherein the skirt is constructed of an attenuating material to protect the skin of the patient against radiation.
