Abstract

The present invention also features a brachytherapy system comprising a spiral cut tube having a first end and a second end; a radioactive brachytherapy source (RBS) disposed on the first end of the spiral cut tube; and a handle and a generally hollow cannula disposed on the handle, wherein a channel is disposed in the handle aligned with the hollow cannula, and the spiral cut tube and RBS are adapted to slide within the channel and the hollow cannula.

Claims

1. A brachytherapy device comprising a handle having a radiation shielding PIG for shielding a RBS, at least a portion of the radiation shielding PIG is generally visually clear, transparent, or translucent.

2. The brachytherapy device of claim 1, wherein the portion of the radiation shielding PIG that generally visually clear, transparent, or translucent is a window.

3. The brachytherapy device of claim 1, wherein the handle is constructed from a material comprising plastic, glass, a polyetherimide, poly (methyl methacrylate), acrylic polysulfone, polycarbonate, polypropylene, or a combination thereof.

4. The brachytherapy device of claim 1 further comprising a distal portion for placement around a portion of a globe of an eye, the distal portion has a radius of curvature between about 9 to 15 mm and an arc length between about 25 to 35 mm;

a proximal portion having a radius of curvature between about an inner cross-sectional radius of the cannula and about 1 meter; and

an inflection point which is where the distal portion and the proximal portions connect with each other;

wherein the handle is attached to the proximal portion.

5. The brachytherapy device of claim 1, wherein the radiation shielding PIG is constructed from a material comprising a polyetherimide, polysulfone, polycarbonate, or polypropylene.

6. The brachytherapy device of claim 1, wherein a visual landmark is disposed on the PIG, the visual landmark functions as a reference point for orientation before or during a surgical procedure.

7. The brachytherapy device of claim 1 further comprising a means of moving a RBS within the handle.

8. The brachytherapy device of claim 7 further comprising a control cable system for manipulating the means of moving the RBS.

9. The brachytherapy device of claim 8, wherein an actuator handle is disposed on a second end of the control cable system.

12. The brachytherapy device of claim 1 further comprising a secondary radiation shield attachable to the handle.

38. A cannula comprising a sensor for detecting a presence of an RBS at a position within the cannula, the sensor is operatively connected to both a power source and an alert system, wherein upon detection of the presence of the RBS at the position within the cannula the sensor triggers the alert system to notify a user that the RBS is at the position within the cannula.

39. The cannula of claim 38, wherein the sensor detects the presence of the RBS in a treatment zone.

40. The cannula of claim 38, wherein the sensor activates a light source when the RBS is detected in the treatment zone.

41. The cannula of claim 38, wherein the sensor is an electrical system.

52. A PIG having an internal chamber, the PIG comprising a sensor adapted for (i) detecting presence of a radioactive source or a carrier within the internal chamber, (ii) detecting removal of a radioactive source or a carrier within the internal chamber, or (iii) both detecting presence of a radioactive source or a carrier within the internal chamber and detecting removal of the radioactive source or the carrier within the internal chamber, the sensor is operatively connected to both a power source and an alert system, wherein upon detection of presence of the radioactive source or the carrier within the internal chamber the sensor triggers the alert system to notify a user that the radioactive source is within the internal chamber of the or wherein upon detection of removal of the radioactive source or the carrier within the internal chamber the sensor triggers the alert system to notify a user that the radioactive source is removed from the internal chamber of the PIG.

53. The PIG of claim 52 wherein the sensor can detect the presence of a mass being stored within the internal chamber, the mass includes a radioactive source.

55. The PIG of claim 52 wherein the alert system provides an audio alert.

56. The PIG of claim 52 wherein the sensor is an optical sensor.

57. The PIG of claim 52 wherein the sensor is an electrical system.
