Automated system for the radiation treatment of a desired area within the body of a patient
First Claim
1. In a transfer device usable in a system for intraluminal treatment of a selected site in a body of a patient by at least one treating element advanced through a lumen in the transfer device into a lumen of a separate catheter by means of pressurized fluid, the transfer device and catheter defining a fluid path for pressurized fluid and a treating element residing in a cartridge removably received by the transfer device, the transfer device further comprising:
- a gate moveable between first and second positions to selectively permit or prevent the treating element from moving from the treating element cartridge to the catheter;
a first release button to permit disassembly of the catheter from the transfer device upon manipulation of the first button;
a second release button to permit the treating element cartridge to be separated from the transfer device upon manipulation of the second button;
an actuator assembly to control the gate and to permit manipulation of the first and second release buttons only when the actuator assembly controls the gate to prevent the treating element from moving from the treating element cartridge to the catheter.

Abstract
A transfer device usable in a system for intraluminal treatment of a selected site in a body of a patient in which the transfer device comprises an integral pump for pressurizing and circulating fluid through a fluid path defined by the transfer device and associated catheter. A removable fluid cartridge is provided including a reservoir from which fluid is drawn by the pump and into which fluid is returned after being circulated through the fluid path. The pump may be a peristaltic pump and the fluid cartridge may include an elongated fluid pick-up having an inlet through which fluid is introduced into the transfer device. The fluid pick-up is sized in length so that the inlet is always submerged in the fluid regardless of the orientation of the transfer device. A removable treatment cartridge having a lumen forming part of the fluid path may also be provided, and a storage sleeve for the treatment cartridge may be of a radiation-blocking material, such as quartz. Further, the treatment cartridge may have a memory for storing and indicating selected information about the treating element.
