System and Method for Determining Implanted Device Orientation
First Claim
1. A system for detecting the orientation of an implant component, the system comprising:
- (a) an implantable component, wherein the implantable component comprises a first coil operable to transmit a first signal having a phase, wherein the implantable component is configured to be implanted within a patient;
(b) an external component, wherein the external component comprises a second coil operable to transmit a second signal having a phase; and
(c) a logic component configured to compare the phase of the first signal with the phase of the second signal, wherein the logic component is further configured to determine an orientation of the first coil relative to the second coil based on a comparison of the phase of the first signal with the phase of the second signal.

Abstract
A system is operable to detect the orientation of an implant component. The system comprises an implantable component, an external component, and a logic component. The implantable component comprises a first coil operable to transmit a first signal having a phase. The external component comprises a second coil operable to transmit a second signal having a phase. The logic component is operable to compare the phase of the first signal with the phase of the second signal. The logic component is further configured to determine an orientation of the first coil relative to the second coil based on a comparison of the phase of the first signal with the phase of the second signal. The system may be used to determine the orientation of an injection port in an implanted gastric band system. The system may alternatively be used in a variety of other types of systems.

19. A method of detecting the orientation of an implanted component, the method comprising:
-
(a) providing an external coil external to a patient, wherein the patient has an implanted component operable to transmit a first signal having a phase, wherein the implanted component has a center, wherein the external coil is operable to transmit a second signal having a phase;
(b) positioning the external coil at a location approximately over the center of the implanted component;
(c) receiving the first signal transmitted by the implanted component;
(d) comparing the phase of the first signal with the phase of the second signal; and
(e) determining the orientation of the implanted component relative to the external coil, based on the comparison of the phase of the first signal and the phase of the second signal. - View Dependent Claims (20)
