Method and apparatus for guiding an external needle to an implantable device
First Claim
1. A system comprising:
- an implantable device having a port and a localizer configured to generate a navigation field, the port including an insertion axis;
an instrument including a tracking device configured to sense the navigation field;
a display device; and
a processor system operable with the tracking device and the display device and configured to determine a real-time location of the instrument relative to the port and a trajectory of the instrument relative to the insertion axis of the port;
wherein the processor system is configured to cause the display device to graphically render the instrument in the form of a plurality of two or three-dimensional rings positioned around an axis coincident with the determined trajectory and in an axially spaced apart relation to each other along the axis, and wherein a first ring of the plurality of rings is positioned at the determined location of the instrument relative to a graphical representation of the location of the port.

Abstract
A system can include an implantable device, an instrument, a display device and a processor. The implantable device can include a port and a localizer for generating a navigation field. The instrument can include a tracking device for sensing the navigation field. The processor can be operably coupled to the tracking and display devices and operable to determine a real-time location of the instrument relative to the port and a trajectory of the instrument relative to an insertion axis of the port. The processor system can be operable to cause the display device to graphically render the instrument as a plurality of two or three-dimensional rings positioned around an axis coincident with the determined trajectory and in spaced relation to each other along the axis. A first ring of the plurality of rings can be positioned at the determined instrument location relative to a graphical representation of the port location.

22. A method comprising:
-
displaying a graphical representation of a target port of an implantable device on an image area of a display device; registering a trackable instrument to the image area of the display device to facilitate displaying a real-time location and trajectory of the instrument in the image area; determining the real-time location and trajectory of the instrument relative to the target port; displaying a graphical rendering of the instrument as a two or three-dimensional navigable object having a trajectory orientated about the determined real-time trajectory and being positioned at the determined real-time location of the instrument relative to the target port, wherein displaying a graphical rendering of the instrument as a two or three-dimensional object includes displaying a plurality of two or three-dimensional rings positioned around an axis coincident with the determined trajectory of the instrument and axially spaced apart a predetermined distance from each other along the axis, the plurality of rings including at least a first ring indicative of a location of the instrument, and a last ring cooperating with at least the first ring to indicate at least the trajectory of the instrument; orientating the trajectory of the instrument with the target port by aligning the graphically rendered trajectory of the instrument with the graphical representation of the target port; navigating the instrument relative to the target port by aligning the graphically rendered location of the instrument with the graphical representation of the target port; and displaying a separate graphical indicator in the image area once the instrument location and trajectory are aligned with the target port. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A method comprising:
-
identifying an implantable infusion device model manually from a preconfigured menu of infusion device models via a portable processor system and a display device, or automatically from data communicated over a telemetry system; determining if the identified device model includes a single target port or multiple ports and, if the selected device model includes multiple ports, selecting one of the multiple ports as the target port; displaying a graphical representation of the identified device model including a graphical representation of the target port in an image area of the display device; registering a trackable instrument to the image area of the display device to facilitate displaying a real-time location and a trajectory of the instrument in the image area; determining the real-time location and trajectory of the instrument relative to the target port; displaying a graphical rendering of the instrument in the form of a plurality of two or three-dimensional rings along the axis positioned around a non-illustrated axis coincident with the determined trajectory of the instrument and axially spaced apart a predetermined distance from each other along the axis such that the rings are displayed perpendicular to the trajectory of the instrument, the plurality of rings including a first ring indicative of a location of the instrument, and a last ring cooperating with remaining rings of the plurality of rings therebetween to indicate at least the trajectory of the instrument; orientating the instrument such that the trajectory of the instrument is aligned with an insertion axis of the target port by aligning the plurality of rings in the image area to be concentric with each other along a view direction parallel to the insertion axis of the target port whereby the axis of the plurality of rings is in parallel alignment with the insertion axis of the target port; and navigating the instrument relative to the graphical representation of the target port such that the first ring of the plurality of rings aligned concentric with each other is positioned over the graphical representation of the target port. - View Dependent Claims (41, 42, 43)
