The Watson-Marlow Pumps Group, Wilmington, MA, introduced a new range of 400RXMD panelmount pumps designed specifically for medical device specialists serving the surgical ablation market. A range of precise pressure settings tailors products for specific customer applications, and the pumps are delivered with pre-set pressure performance for effective catheter ablation. An innovative mechanism has also been introduced giving improved flow accuracy, while a tube holder ensures the tube locates in the right position every time the safety lid is closed, providing rapid, trouble-free tube loading.
This simple, robust and unique pump solution is great for equipment that uses radio frequency ablation, where the pump is part of a larger system that includes an RF generator, and a catheter or needle. The 400RXMD pumps cooling fluid to provide precise temperature control which produces a more effective treatment and prevents scarring. The cooling fluid helps concentrate the RF energy on the target area which is particularly important when ablating large volumes of tissue such as in the treatment of cancer. The 400RXMD pump offers flows up to 450ml/min at 550rpm and delivers the user a pressure range up to 6 bar. With two stepper motors and one brushless motor option available, the 400RXMD pump has the unique ability to set pressure, flow and rotation direction according to each customer’s needs.
