    摘要： A microwave ablation system includes an antenna assembly configured to deliver microwave energy from a power source to tissue. One or more electrodes are disposed on the antenna assembly and are configured to be positioned relative to tissue upon insertion of the antenna assembly into tissue. The one or more electrodes are configured to generate a feedback signal in response to an electrical signal supplied thereto from the power source. The feedback signal corresponds to the proximity of tissue relative to the at least one electrode and is configured to be compared to a predetermined parameter to determine a depth of the insertion of the antenna assembly into tissue. The power source is configured to control the delivery of microwave energy to the antenna assembly based on the comparison.

    摘要： An ablation probe having a ground plane is disclosed. The disclosed probe includes an inner conductor coaxially disposed within an outer shield. One or more ground plane(s) oriented substantially transversely to a longitudinal axis of the probe are joined to the outer shield. One or more dielectric(s) may be disposed around the inner conductor or upon a surface of a ground plane. The probe may include a rigid or flexible catheter disposed around the outer shield to define a conduit therebetween to enable the delivery of pressurized fluid to an inflatable balloon disposed around a ground plane. A semicylindrical housing having a circumferential surface and a distal surface may be included. A proximal edge of the circumferential surface of the semicylindrical housing may be joined to a circumferential edge of a ground plane. An opening may be defined in the distal surface of the semicylindrical housing, through which the inner conductor may extend distally.

    摘要： A radiation detector disposed on a microwave antenna assembly to receive unintended field exposure in an insufflated abdomen. The radiation detector includes a receiving antenna made up of at least two pieces of metal externally attached to the microwave antenna within the abdomen. The radiation detector is adapted to receive errant microwave energy that resonates in the abdomen. A rectifier is coupled between the two pieces of metal, where the pieces of metal are strips, rings, patches, or other geometric combinations. The rectifier is adapted to rectify at least a portion of the errant microwave energy. A filter is coupled to the rectifier and is adapted to convert the rectified microwave energy into a detection signal. An inflatable stop is located on a distal end of the microwave antenna and the inflatable stop is inflated when inserted within the abdomen. The inflated stop prevents inadvertent removal of the microwave antenna.

    摘要： A device for directing energy to a target volume of tissue includes an inner conductor having a length and an outer conductor coaxially surrounding the inner conductor along the length. The outer conductor has a proximal portion and a distal portion. The distal portion of the outer conductor is provided with a number of apertures N defined therein for radiating energy, where N is an integer greater than 1, each aperture having a size and extending at an angle relative to a longitudinal axis of the outer conductor. At least one of the size and the angle of each aperture is varied in relation to the other apertures N−1 such that the energy radiated along the distal portion is substantially uniform.
