Abstract
Implantation imaging techniques are presented herein to provide a surgeon with visual feedback during implantation of an implantable medical device in a recipient. The implantation imaging techniques may include the generation of a magnetic field that induces a voltage at a coil positioned in the recipient. The induced voltage is used to determine the orientation of the coil positioned in the recipient relative to direction of the magnetic field.
Claims20
A system comprising:
- a first external coil arranged about a first axis and configured to generate a magnetic field within a surgical region;
- an elongate assembly configured to be inserted into a recipient located in the surgical region and comprising an assembly coil configured to detect the magnetic field generated by the first external coil and to generate a voltage for use in determining an orientation of the assembly coil with respect to the first axis.
A method comprising:
- inserting an elongate assembly comprising an assembly coil into a recipient located in a surgical region;
- generating a magnetic field within the surgical region with a first external coil that is arranged about a first axis and positioned in proximity to the surgical region;
- detecting the magnetic field at the assembly coil such that a voltage is induced at the assembly coil;
- and
- determining, based on the induced voltage, an orientation of the assembly coil with respect to the first axis.
