Needle to port trajectory indicator
First Claim
1. A method comprising:
- determining the orientation of a port of an implantable infusion device relative to a needle for insertion into the port, wherein the port has an axis defining a target trajectory for the needle and wherein the needle has a longitudinal axis;
displaying a trajectory of the needle relative to the port by graphically rendering the axis of the port as a target structure having a reference area and by graphically rendering the longitudinal axis of the needle as an object moveable relative to the target structure;
updating the graphical rendering of the longitudinal axis of the needle as the needle is being inserted into the port,wherein occupation of the reference area by the object indicates trajectory alignment of the axis of the port and the longitudinal axis of the needle.

Abstract
A system includes (i) a needle for insertion into a port of an implantable infusion device, and (ii) a receiver apparatus having a port location signal receiver module capable of receiving a signal from the implantable infusion device regarding spatial orientation of the port. The system further includes a processor operably coupled to the receiver apparatus and capable of determining the orientation of the needle relative to the port based on the received signal. The system also includes a display operably coupled to the processor. The processor is configured to cause the display to graphically render trajectory of the needle relative to the port. The port is graphically rendered as a target structure having a reference area. The needle is graphically rendered as an object moveable relative to the target structure. Occupation of the reference area by the object indicates trajectory alignment of the port and the needle.

4. A non-transitory computer-readable medium containing instructions that when implemented cause a needle alignment medical device system to:
-
process information from a signal transmitted from an implantable infusion device regarding the location of a port of the infusion device, the port having an axis defining a target trajectory for a needle; determine the orientation of the needle relative to the port based on the information from the transmitted signal, wherein the needle has a longitudinal axis; and graphically render trajectory of the needle relative to the port, wherein the axis of the port is graphically rendered as a target structure having a reference area and the longitudinal axis of the needle is graphically rendered as an object moveable relative to the target structure; updating the graphical rendering of the longitudinal axis of the needle as the needle is being inserted into the port, wherein occupation of the reference area by the object indicates trajectory alignment of the axis of the port and the longitudinal axis of the needle.

5. A system for aligning a needle with a port of an implantable infusion device, the port having an axis defining a target trajectory for the needle and the needle having a longitudinal axis, the system comprising:
-
a receiver apparatus having a port location signal receiver capable of receiving a signal from the implantable infusion device regarding spatial orientation of the port, wherein the receiver apparatus is configured to be fixed relative to the longitudinal axis of the needle as the needle is being inserted into the port; a processor operably coupled to the receiver apparatus and capable of determining the orientation of the axis of the needle relative to the axis of the port based on the received signal; and a display operably coupled to the processor, wherein the processor is configured to cause the display to graphically render a trajectory of the needle relative to the port, wherein the axis of the port is graphically rendered as a target structure having a reference area and the axis of the needle is graphically rendered as an object moveable relative to the target structure, wherein the processor is configured to update the graphical rendering of the axis of the needle as the needle is being inserted into the port, and wherein occupation of the reference area by the object indicates trajectory alignment of the port and the needle. - View Dependent Claims (6, 7, 8, 9, 10, 11)
