TRACKABLE IMPLANTABLE SENSOR DEVICES, SYSTEMS, AND RELATED METHODS OF OPERATION
First Claim
1. An implantable biocompatible sensor unit, comprising:
- a sensor body comprising a biocompatible material and having at least one sensor element configured for in vivo placement proximate a tumor treatment site and configured to provide data corresponding to treatment thereof;
a transmitter coil and associated electronic components within the sensor body configured for wireless transmittal of the data to a spatially remote receiver; and
a high-atomic weight member within the sensor body configured to be detectable by an imaging modality,wherein the sensor unit is configured to be inductively powered to wirelessly transmit the data to the remote receiver while remaining implanted proximate the tumor treatment site.

Abstract
An implantable biocompatible sensor unit includes a sensor body of a biocompatible material configured for in vivo placement proximate a tumor treatment site. The sensor body includes at least one sensor element are configured to provide data corresponding to treatment of the tumor treatment site. The sensor body further includes a transmitter coil and associated electronic components configured for wireless transmittal of the data to a spatially remote receiver. In addition, the sensor body includes a high-atomic weight member that is configured to be detectable by an imaging modality. The sensor unit is configured to be inductively powered to wirelessly transmit the data to the remote receiver while remaining implanted proximate the tumor treatment site. Related medical systems and methods of operation are also discussed.

13. A medical system for patients undergoing treatment for cancer, the system comprising:
-
at least one wireless implanted sensor unit configured for in vivo placement proximate a tumor treatment site, the at least one sensor unit being configured to provide data including at least one sensed internal parameter, the at least one sensor unit including a high-atomic weight member held in a biocompatible housing and configured to be visualized as a fiducial marker by an imaging modality, wherein the at least one sensor unit is configured to be inductively powered to wirelessly transmit the data; and an external reader configured to inductively power the at least one sensor unit and configured to receive the data from the at least one sensor unit, wherein the system is configured to dynamically monitor selected in vivo parameters associated with one or more of dose and/or processing of a therapy administered to the tumor treatment site based on the data from the at least one sensor unit. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method for treating a patient for cancer, the method comprising:
-
positioning at least one wireless sensor unit including at least one sensor element and a high-atomic weight member therein in the body of the patient proximate a tumor treatment site; determining a position of the sensor unit proximate to the tumor treatment site using an imaging modality based on the high-atomic weight member; administering a radiation therapy to the patient based on the determined position; detecting in vivo a signal from the at least one sensor unit corresponding to the dose of the administered therapy proximate the tumor treatment site; relaying the signal to a location external of the patient'"'"'s body; and dynamically adjusting administration of the therapy to thereby improve the localized delivery of radiation dose based on changes in the determined position. - View Dependent Claims (21)
