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. |

DETAILED DESCRIPTION The present invention comprises an automated catheter based radiation delivery system and its method of use for treatment of a desired area within the body of a patient.
The system includes a delivery catheter, treatment elements, and a transfer device that electromechanically delivers the source train through the catheter to the selected location within a patient's body.
The transfer device prompts the user to proceed appropriately through the procedure by displaying graphics and text via a LCD (Liquid Crystal Display) with a series of individual display prompts combining with operative input controls allows for an intuitive user interface.
The assembled transfer device can be seen in FIGS.
1 3.
The exterior of the transfer device 10 is ergonomically designed to be easily held with either or both hands, making it equally adaptable for right and left-handed clinicians.
As can be seen in FIGS.
1 and 2, curved handgrips 12 with finger rests 14 and thumb rests 16 are located on both the left and right sides of the transfer device 10.
Alternatively, the device 10 can rest in the palm of the user's hand or on a flat surface.
The controls are easily reachable with the thumbs when both hands are supporting the device.
An upper housing portion 18 and a lower housing portion 20 fit together to create the shell that holds the internal components openings in the upper housing portion 18 allow a user to access a display 22, control buttons 24, 26, 28, 30, indicator LEDs (Light-emitting Diodes) 32, 34, 36, and a latch member 38.
The upper portion 18 also includes a window 40 for viewing a sleeve 42, which houses a source train 43 (comprising treatment elements and marker seeds), and a pin gate 44.
The sleeve 42 is preferably made of a radiation-blocking material, such as quartz, synthetic fused silica, polycarbonate plastic, etc.
The lower housing portion 20 has a central opening for mounting the power supply for the device, most likely a replaceable or rechargeable battery pack 48
