摘要： An electrosurgical instrument having a microwave ablation antenna dimensioned to be suitable for insertion into a pancreas via a surgical scoping device, to provide a rapid and accurate alternative to known RF ablation techniques. The electrosurgical instrument comprises: a proximal coaxial transmission line for conveying microwave electromagnetic (EM) energy; a distal radiating portion; and an intermediate impedance transformer arranged to match an impedance of the coaxial transmission line to an impedance of the distal radiating portion, wherein the distal radiating portion comprises a microwave antenna for emitting the microwave EM energy conveyed by the coaxial transmission line, wherein the distal radiating portion has a maximum outer diameter less than an outer diameter of the coaxial transmission line. With these features, the instrument is able to deliver microwave energy via a small diameter structure.

摘要： An exemplary ablation system is provided. The system is designed for safe and efficacious energy delivery into tissue by, for example, emitting energy in a controlled, repeatable manner that allows for feedback and energy emission titration based on sensed parameters (e.g., tissue temperature) measured during ablation. The system may include a switching antenna for both heating of target tissue and radiometry to monitor the temperature of the heated tissue. For example, the switching antenna may include a monopole formed by proximal and distal radiating elements, such that the proximal radiating element includes a short to defeat a choke action of the proximal radiating element. The system further includes a processor for calculating the temperature of the target tissue and estimating volume of the ablation lesion based on the target tissue temperature.

摘要： An electrosurgical instrument for use in minimally invasive surgical techniques that provides a small scale localized microwave field capable of precisely ablating tissue, e.g. in the lungs, through suitable selection of geometry and material for a radiating distal tip thereof. The instrument may be used with a bronchoscope having a power delivery structure formed within the instrument cord thereof. A vision system may be incorporated into the energy delivery structure. The instrument comprise a coaxial cable for conveying microwave energy to a radiating tip portion that comprises a dielectric tip and a distal conductive portion that extends longitudinally therein. The dielectric tip has a dielectric constant greater than a dielectric material within the coaxial cable. The distal end of the device is designed to facilitate efficient microwave energy delivery into lung tumour tissue to achieve a localized volume of ablation.

摘要： Systems, assemblies, and methods to treat pulmonary diseases are used to decrease nervous system input to distal regions of the bronchial tree within the lungs. Treatment systems damage nerve tissue to temporarily or permanently decrease nervous system input. The treatment systems are capable of heating nerve tissue, cooling the nerve tissue, delivering a flowable substance that cause trauma to the nerve tissue, puncturing the nerve tissue, tearing the nerve tissue, cutting the nerve tissue, applying pressure to the nerve tissue, applying ultrasound to the nerve tissue, applying ionizing radiation to the nerve tissue, disrupting cell membranes of nerve tissue with electrical energy, or delivering long acting nerve blocking chemicals to the nerve tissue.

摘要： A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to heat tissue to create lesions without ablating the tissue. The system includes a first treatment device having at least one electrode for applying radiofrequency energy to tissue, a controller including a connector to which a first treatment device is coupled for use, and a generator for applying radiofrequency energy to the electrodes. The controller controls application of energy so that the tissue is thermally treated to create lesions but preventing thermal treatment beyond a threshold which would ablate the tissue.
