    摘要: A surgical ablation system employing an ablation probe having a deployable ground plane is disclosed. The disclosed system includes a source of ablation energy and a source of electrosurgical energy, and a switching assembly configured to select between ablation and electrosurgical modes. The probe includes a cannula having a shaft slidably disposed therein. The shaft includes a deployable ground plane electrode assembly and a needle electrode disposed at distal end of the shaft. As the shaft is extended distally from the cannula, the ground plane electrode unfolds, and the needle electrode is exposed. Electrosurgical energy is applied to tissue via the needle electrode to facilitate the insertion thereof into tissue. Ablation energy is applied to tissue via the needle electrode to achieve the desired surgical outcome. The shaft, ground plane electrode and needle electrode are retracted into the cannula, and withdrawn from the surgical site.

    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 subjects 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 cut-rent 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 microwave ablation system for treating tissue includes an assembly of antennas adapted to connect to a microwave generator. The microwave generator generates microwave energy. Each antenna of the assembly of antennas includes inner and outer conductors. The inner conductor has a length. The outer conductor has a longitudinal axis defined along a length thereof. The outer conductor at least partially surrounding the inner conductor at least partially along the length thereof. One of the inner conductor and the outer conductor is movable with respect to the other. At least one antenna of the assembly of antennas is deployable from a first state for ablating a first ablation region of tissue to a second deployable state for ablating a second ablation region of tissue. The first and second ablation tissue regions overlap to define an aggregate ablation region.

    摘要: The present disclosure relates to devices and methods for the treatment of tissue with microwave energy. The devices and methods disclosed herein utilize an antenna assembly which includes an elongate member, an outer conductor, an inner conductor, at least a portion of which is deployable, and a cooling system. The cooling system disclosed herein may significantly curtail any theoretical, or potential negative effects upon the target tissue experienced during the transmission of microwave energy to the antenna assembly due to ohmic heating.
