Automated system for the radiation treatment of a desired area within the body of a patient
First Claim
1. A transfer device comprising a lumen usable in a system for intraluminal treatment of a selected site in a body of a patient by at least one discrete treating element adapted to be advanced through the lumen in the transfer device into a lumen of a separate catheter by means of pressurized fluid, the transfer device and the catheter defining a closed fluid path for pressurized fluid, the transfer device further comprising an integral pump for pressurizing and circulating the fluid through the fluid path and a removable fluid cartridge including a reservoir from which fluid is drawn by the pump and to which fluid is returned after being circulated through the closed fluid path.

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.
