  • Patent number: 10076384
    Abstract: A microwave ablation system and method is disclosed comprising a balloon catheter apparatus and a control system. The balloon catheter apparatus comprises a catheter configured to house a coaxial cable and one or more coolant channels, an inflatable balloon located at the distal end of the catheter, and an antenna positioned in the inflatable balloon and in communication with the coaxial cable. The control system comprises a fluid pump configured to introduce fluid into a proximal end of the catheter, a power amplifier capable of generating microwave energy for delivery to the target tissue zone for at least one energy application cycle ranging from 60 seconds to 600 seconds at a frequency ranging from 2.4 GHz to 2.5 GHz, and a computer system configured to monitor and/or regulate the delivery of microwave energy to the target tissue, the fluid pump, at least one sensor, and antenna reflected power.

  • Patent number: 8162822
    Abstract: A unit of equipment designed for use in endoscopic surgery includes radio frequency identification (RFID) circuitry and a network interface. The RFID circuitry can be used to store information of various types, such as component usage tracking information, user preferences, usage logs, error logs, device settings, etc. The network interface allows the unit to communicate over an external network with a remote server. Information, such as information stored in the RFID circuitry or in a separate memory, may be sent over the network to a desired destination, such as a server operated by the manufacturer of the equipment.
