Apparatus for in situ radiotherapy
First Claim
1. Apparatus for in situ radiotherapy of a patient, comprising:
- a flexible guide tube having a proximal end for receiving a radioisotope and a distal end for positioning the guide tube within a patient to be treated;
sealing means comprising a plug filling a portion of said guide tube for sealing the distal end of the guide tube; and
an anchor including anchor connector means forto the flexible guide releasably connecting the anchor tube, and patient connection means for connecting the anchor permanently to the patient.

Abstract
Apparatus for in situ radiotherapy has a flexible catheter having a proximal end for receiving a radioisotope and a distal end for positioning the flexible catheter within a patient to be treated. An anchor, which is permanently connectable to tissues deep inside the patient, has a sealing collar connected to it which seals the distal end of the catheter. The catheter also includes a plug near the distal end which seals the distal end in addititon to the seal provided by the sealing collar. The anchor has a penetration point connected to it to assist a surgeon in implanting the catheter within a tumor. A threaded fastener on the anchor is screwed into the catheter. The flexible catheter can be released remotely from the anchor by unscrewing it. A suture eye is connected to the anchor. The suture eye may be sutured to healthy tissue within the patient when the apparatus is implanted to secure the anchor to the patient. When the radioisotope is not being received, the proximal end of the catheter is sealed by a cylindrical plug connected to a manipulation handle.
