Invasive medical device with position sensing and display
First Claim
1. Apparatus for performing a medical procedure on a tissue within a body of a subject, comprising:
- a wireless tag configured to be fixed to the tissue and adapted to emit radiation, thereby causing first signals to be generated indicative of location and orientation coordinates of the tag in the body;
an invasive medical tool, comprising;
a probe, which is adapted to penetrate into the body so as to reach the tissue;
a handle, fixed proximally to the probe, and adapted to be manipulated by an operator of the tool; and
a display, mounted on the handle, and adapted to present a visual indication to the operator of an orientation of the probe relative to the tag based on the location and orientation coordinates; and
a processing unit, coupled to process the first signals so as to determine the location and orientation coordinates of the tag relative to the probe, and to drive the display responsive to the location and orientation coordinates.

Abstract
Apparatus for performing a medical procedure on a tissue within a body of a subject includes a wireless tag configured to be fixed to the tissue and adapted to emit radiation, thereby causing first signals to be generated indicative of a location of the tag in the body. An invasive medical tool includes a probe, which is adapted to penetrate into the body so as to reach the tissue. A handle is fixed proximally to the probe, for manipulation by an operator of the tool. A display, mounted on the handle, presents a visual indication to the operator of an orientation of the probe relative to the tag. A processing unit processes the first signals so as to determine coordinates of the tag relative to the probe, and drives the display responsive to the coordinates.

13. A method for performing a medical procedure on a tissue within a body of a subject, comprising:
-
fixing a wireless tag to the tissue; actuating the tag to emit radiation, thereby causing first signals to be generated indicative of location and orientation coordinates of the tag in the body; introducing an invasive medical tool into the body by manipulating a handle of the tool; processing the first signals so as to determine the location and orientation coordinates of the tag relative to the tool; responsive to location and orientation the coordinates, displaying a visual indication on the handle of the tool of an orientation of the tool relative to the tag; and
advancing the tool into the body to the tissue by manipulating the handle while observing the visual indication so that the tool reaches the tissue. - View Dependent Claims (14, 15, 16, 17, 20, 21, 22, 24)
