Abstract
A system for deploying needles in tissue includes a controller and a visual display. A treatment probe has both a needle and tines deployable from the needle which may be advanced into the tissue. The treatment probe also has adjustable stops which control the deployed positions of both the needle and the tines. The adjustable stops are coupled to the controller so that the virtual treatment and safety boundaries resulting from the treatment can be presented on the visual display prior to actual deployment of the system.
Claims21
A method for deploying a plurality of tines from a needle in tissue, said method comprising:
- providing a real-time image of the tissue including an anatomical feature to be treated on a display;
- penetrating the needle into the tissue proximate the anatomical feature;
- deploying the plurality of tines from the needle, wherein at least one of a treatment boundary or a safety boundary is projected onto the display, wherein the safety boundary comprises a minimum threshold distance beyond the treatment boundary where a risk of damaging tissue during the treatment is reduced;
- and
- adjusting an extent of tine deployment to change a size and/or shape of the treatment and/or safety boundary projected onto the display;
- wherein the treatment is delivered through the plurality of tines after adjusting the extent of tine deployment.
A method for deploying a plurality of tines from a needle in tissue, said method comprising:
- providing a real time ultrasound image of the tissue including an anatomical feature to be treated on a display;
- displaying a probe as the probe is positioned near the anatomical feature, the probe including the plurality of tines;
- projecting an image of at least one of a treatment region for a treatment or a safety region on the real time image, wherein the safety boundary comprises a minimum threshold distance beyond a boundary of the treatment region where a risk of damaging tissue during the treatment is reduced;
- adjusting a size and a position of a projected boundary of the projected image of the at least one of the treatment region or the safety region on the real time ultrasound image, wherein adjusting the size and the position of the projected boundary comprises user adjustment of a user interface;
- and
- displaying the plurality of tines on the real time ultrasound image as the plurality of tines is deployed from the probe, wherein the plurality of tines is positioned to provide the treatment within the projected boundary after the projected boundary has been adjusted,
- wherein the plurality of tines is deployed from the probe by distal advancement of a slider on the handle of the probe.
A method for deploying a plurality of tines from a needle in tissue, said method comprising:
- providing a real time image of the tissue including an anatomical feature to be treated on a display;
- displaying a probe as the probe is positioned near the anatomical feature, the probe including the plurality of tines;
- projecting an image of at least one of a treatment region for a treatment or a safety region on the real time image, wherein the safety boundary comprises a minimum threshold distance beyond a boundary of the treatment region where a risk of damaging tissue during the treatment is reduced;
- adjusting at least one of a size or a position of a projected boundary of the projected image of the at least one of the treatment region or the safety region on the real time image, wherein adjusting the at least one of the size or the position of the projected boundary comprises user adjustment of a first interface;
- and
- displaying the plurality of tines on the real time image as the plurality of tines is deployed from the probe, wherein the plurality of tines is positioned relative to the probe and the tissue to provide the treatment within the projected boundary after the projected boundary has been adjusted,
- wherein the plurality of tines is deployed from the probe by operation of a second interface on the handle of the probe.
