Abstract:
1. A system for treating an anatomical feature in tissue, said system comprising: a microprocessor configured to generate and project virtual boundary lines defining a projected treatment and/or projected safety region on a real time image of the tissue; a real time image display configured to display the real time image and the projected virtual boundary lines; a treatment probe having a shaft, a handle, a needle structure deployable from the shaft, a slider configured to position the needle structure relative to the shaft and an imaging transducer, wherein the transducer is connectable to the microprocessor that further generates the real time image; a stop structure positionable along a length of the handle of the treatment probe, wherein a position of the stop structure of the handle of the probe (1) controls at least one of a position and a size of the virtual boundary lines defining the treatment and/or safety region projected on the real time image display and (2) physically limits movement of the slider to control deployment of the needle structure from the shaft so that subsequent treatment of the tissue is within the projected treatment and/or safety region, wherein the stop structure is positionable independently of the position of the slider and needle structure.
