[New infusion port for intermittent infusion chemotherapy]

We devised a new infusion port for the intermittent infusion chemotherapy to the hepatic artery. This device has the following advantages: 1. A large needle (18 G) may be used to infuse the medicine because of the special urethane gum parts of the port. 2. One need only exchange the port for a new one or to the tube for continuous infusion chemotherapy under local anesthesia. 3. This port can be employed for arterial embolization because of its large inner diameter. In this report we introduce the structure and advantages of this new port device.
