摘要:
An irrigated catheter includes a catheter body having both proximal and distal irrigation passageways. A first fluid delivery tube feeds the proximal irrigation passageway and is fluidly isolated from the distal irrigation passageway, while a second fluid delivery tube feeds the distal irrigation passageway and is fluidly isolated from the proximal irrigation passageway. Typically, the first and second fluid delivery tubes will be unitary, at least through the catheter body. The overall shape of the first and second fluid delivery tubes, as well as their respective lumens, may vary as necessary for a particular application of the irrigated catheter. The system also includes an irrigation fluid source and at least one pump to deliver the irrigation fluid through the irrigation passageways. Typically, the pump will be a volume-driven pump, such as a rolling pump.
