US Patent:

20220386890, Dec 8, 2022

Filed:

Jun 6, 2022

Appl. No.:

17/805617

Inventors:

- Aliso Viejo CA, US
John E. Greene - Valley Center CA, US

International Classification:

A61B 5/06
A61B 90/00
A61B 5/00

Abstract:

An impedance reflector apparatus, systems, and methods are provided for detecting a marker implanted within tissue that includes a switch for changing a configuration of an antenna of the marker. The apparatus includes a set of transmit electrodes coupled to a signal generator for transmitting a drive current into tissue to generate an electromagnetic field around the marker, a set of receive electrodes configured to detect voltage signals within the tissue corresponding to the electromagnetic field, and a light source for delivering light pulses into the body to open and close the switch to change the configuration of the antenna of the marker. A processor coupled to the receive electrodes processes the detected voltage signals to identify changes in the electromagnetic field that are synchronized with the light pulses to determine whether the marker is operating properly.

International Classification:

A61B 90/00
A61B 5/06

Abstract:

Apparatus, systems, and methods are provided for localization of a needle within a patient's body using markers. In an exemplary embodiment, a probe includes a distal end for placement against a surface of the region and one or more antennas for transmitting electromagnetic signals into and receiving reflected signals from the region. A processor processes the modulated reflected signals at one or more of the surface locations to determine marker locations along the needle and generate a three-dimensional model of the body region and needle.

International Classification:

A61B 5/06
A61B 5/00

Abstract:

Apparatus, systems, and methods are provided for localization of a region within a patient's body using markers implanted within the region. In an exemplary embodiment, a probe includes a distal end for placement against a surface of the region; one or more antennas for transmitting electromagnetic signals into and receiving reflected signals from the region; a light source for delivering light pulses into the region whereupon the markers modulate reflected signals. A processor of the probe processes the modulated reflected signals at one or more of the surface locations to determine marker locations within the region to obtain a reference frame, determine distance values corresponding to distances from the respective markers to the distal end at each of the surface locations, and determine coordinates of the surface locations relative to the reference frame to generate a three dimensional model of the body region.

International Classification:

A61B 5/06
A61B 5/05
A61B 5/00
A61B 90/00

Abstract:

Apparatus, systems, and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The system includes a microwave antenna probe for transmitting and receiving electromagnetic signals to detect one or more markers that are implanted within or around the target tissue region. During use, the marker(s) are implanted into a target tissue region, and the microwave antenna probe is placed against the patient's skin to transmit a signal to the marker(s) and to receive the reflected signal from the marker(s) in order to determine the location of the marker(s). A tissue specimen, including the lesion and the marker(s), is then removed from the target tissue region based at least in part on the location information from the microwave antenna probe.
