Abstract
A support tool or a supply assembly that delivers a functional fluid to a patient includes an antenna array for receiving or sensing a navigation field. The navigation field can be generated from a localizer. The localizer can be incorporated or included in an implanted device.
Claims24
A system for determining a location of a trackable instrument with a receiving coil array, comprising:
- a trackable instrument;
- an tracking array associated with the trackable instrument, having:
- tracking portions;
- wherein each of the tracking portions is positioned at vertices of a geometric shape to form the tracking array;
- wherein each of the tracking portions is operable to sense a field to determine position information and orientation information;
- an implantable medical device having a power source;
- a localizer positioned in the implanted medical device operable to emit a field to be sensed by the tracking array;
- a display operable to display a location information of the trackable instrument.
A system for determining a location of a trackable instrument with a receiving coil array, comprising:
- tracking portions positioned substantially in a selected geometric shape;
- each of the tracking portions including a conductive material;
- and
- each of the tracking portions having three individual coils that are aligned on an axis substantially orthogonal to the other two individual coils;
- wherein each of the tracking portions are spaced apart from one another.
A system for determining a location of a trackable instrument with a receiving coil array, comprising:
- twelve conductive coils arranged in the receiving coil array;
- four conductive coil groups where each of the four conductive coil groups has three of the twelve conductive coils;
- and
- a localizer positioned in an implanted medical device operable to emit a field to be sensed by each of the twelve conductive coils;
- wherein each of the four conductive coil groups is positioned at vertices of a tetrahedron;
- wherein fields sensed at each of the four conductive coil groups is operable to determine position information and orientation information for each of the coil groups relative to the localizer.
