摘要:
A medical instrument or device used to decrease blood loss during surgery and/or other medical procedures. The device includes a microwave antenna housed in a handset (or laparoscopic probe) that is placed in close proximity to the tissue of interest. The device runs in the microwave spectrum and receives power from a from a microwave generator. When turned on (triggered), the device delivers microwave energy to tissue, providing a cutting or cautery effect.
摘要:
An improved antenna for microwave ablation uses a triaxial design which reduces reflected energy allowing higher power ablation and/or a smaller diameter feeder line to the antenna.

摘要:
A method and system delivers microwave energy to a vessel, such as a vein for the treatment of varicose veins, in a controllable heating pattern and to provide relatively fast heating and ablation of the vessel. The method and system comprises a microwave delivery device for heating the vessel, and a microwave power source for supplying microwave power to the delivery device. The method and system may also include a cooling system, a temperature monitoring, feedback and control system, an ultrasound or other imaging device, and/or a device for assuring generally uniform energy delivery in the vessel.
摘要:
The present invention relates to comprehensive systems, devices and methods for delivering energy to tissue for a wide variety of applications, including medical procedures (e.g., tissue ablation, resection, cautery, vascular thrombosis, treatment of cardiac arrhythmias and dysrhythmias, electrosurgery, tissue harvest, etc.). In certain embodiments, systems, devices, and methods are provided for treating a tissue region (e.g., a tumor) through application of energy.

摘要:
At least one electrode lead outside the body and leading between an RF ablation power source and the unshielded probes in the patient is shielded to substantially eliminate artifacts during concurrent electronic imaging and RF ablation.
