First Claim
Patent Images
1. A method for deploying at least one needle in tissue, said method comprising:
- positioning a probe having a deployable needle proximate a surface of the tissue;
providing a real time image of the tissue including an anatomical feature to be treated;
overlaying the real time image with a projected treatment region based on the position of the probe;
repositioning the probe to align the projected treatment region on the real time image so that the treatment region includes at least a portion of the anatomical feature to be treated; and
deploying the needle from the probe after the probe has been repositioned;
wherein the probe is positioned in a uterus and the anatomical feature to be treated includes a fibroid.

Abstract
Needles are deployed in tissue under direct ultrasonic or other imaging. To aid in deploying the needle, a visual needle guide is projected on to the image prior to needle deployment. Once the needle guide is properly aligned, the needle can be deployed. After needle deployment, a safety boundary and treatment region are projected on to the screen. After confirming that the safety boundary and treatment regions are sufficient, the patient can be treated using the needle.
