摘要： Devices and methods for cooling microwave antennas are disclosed herein. The cooling systems can be used with various types of microwave antennas. One variation generally comprises a handle portion with an elongate outer jacket extending from the handle portion. A microwave antenna is positioned within the handle and outer jacket such that cooling fluid pumped into the handle comes into contact directly along a portion of the length, or a majority of the length, or the entire length of the antenna to allow for direct convective cooling. Other variations include cooling sheaths which form defined cooling channels around a portion of the antenna. Yet another variation includes passively-cooled systems which utilize expandable balloons to urge tissue away from the surface of the microwave antenna as well as cooling sheaths which are cooled through endothermic chemical reactions. Furthermore, the microwave antennas themselves can have cooling lumens integrated directly therethrough.

摘要： High-strength microwave antenna assemblies (10) and methods of use are described herein. The microwave antenna has a radiating portion (12) connected by a feedline (14) to a power generating source (28), e.g., a generator. The antenna is a dipole antenna with the distal end of the radiating portion being tapered and terminating at a tip to allow for direct insertion into tissue. The antenna can be used individually or in combination with multiple antennas to create a combined ablation field. When multiple antennas are used, microwave energy can be applied simultaneously to all the antennas or sequentially between the antennas. Furthermore, to facilitate positioning the antennas in or near the tissue to be treated, RF energy may be applied at the tip of the antenna to assist in cutting through the tissue.

摘要： A microwave antenna (Fig. 13D) having a curved configuration is described herein. The antenna portion is formed into various shapes whereby the antenna substantially encloses, by a partial or complete loop or enclosure, at least a majority of the tissue to be irradiated. When microwave energy is delivered through the antenna, the curved configuration forms an ablation field or region defined by the curved antenna and any tissue enclosed within the ablation region becomes irradiated by the microwave energy. The microwave antenna is deployed through one of several methods, and multiple curved antennas can be used in conjunction with one another. Moreover, RF energy can also be used at the distal tip of the antenna to provide a cutting tip for the antenna during deployment in tissue.

摘要： This invention is an improved tissue-localizing device with an electrically energized locator element for fixedly yet removably marking a volume of tissue containing a suspect region for excision. The electrical energizing of the locator element facilitates the penetration of the locator element in to subject's tissue and minimizes resistance due to dense or calcified tissues. At least one locator element is deployed into tissue and assumes a predetermined curvilinear shape to define a tissue border containing a suspect tissue region along a path. Multiple locator elements may be deployed to further define the tissue volume along additional paths defining the tissue volume border that do not penetrate the volume. Delivery of electric current may be achieved through monopolar or bipolar electronic configuration depending on design needs. Various energy sources, e.g. radio frequency, microwave or ultrasound, may be implemented in this energized tissue-localizing device.

摘要： A method and system for providing a magnetic transducer are disclosed. The method and system include providing a magnetic element including a free layer, a nonmagnetic spacer layer, a pinned layer, and a pinning layer adjacent to the pinned layer. The free layer is to be biased in a first direction. The pinning layer biases the pinned layer magnetization in a second direction. The pinning layer is oriented along the second direction. A hard bias structure is adjacent to the magnetic element. The hard bias structure magnetization is initialized such that it has a nonzero component along the second direction. The method and system also include performing thermal treatment(s) after initializing the hard bias magnetization. The thermal treatment(s) are above room temperature. The method and system further include resetting the hard bias magnetization substantially along the first direction after the thermal process(es) are performed.
