First Claim
Patent Images
1. An after-loader for providing an implant to a hollow needle, the after-loader comprising:
- a body having a distal end and a proximal end, the distal end including a bevel and a bore;
wherein the bevel is adapted to receive a hub of a first type of brachytherapy needle and the bore is adapted to receive a hub of a second type of brachytherapy needle; and
a radiation shield adapted to be provided over at least a portion of the body; and
wherein the distal end further includes a taper along a portion of a distance from the distal end to the proximal end for providing a friction fit to the shield.
