Abstract
This invention is a transfer device and catheter assembly for the delivery of treatment elements to a selected location within the intraluminal passageways of a patient as part of an intraluminal radiation system. The transfer device includes a gate member that permits the treatment elements to leave the transfer device only if the catheter is attached thereto. A pressure indicator provides a visual indication of the fluid pressure within the transfer device, and a pressure relief valve provides for a release of the fluid if the pressure exceeds a predetermined pressure. Transfer device also includes a treatment element detection system, low power indicator, a counter system, and an electromagnetic locking mechanism to prevent the opening or closing of the gate member when less than all of the treatment elements are in the transfer device.
