NEEDLE TO PORT TRAJECTOR INDICATOR
First Claim
1. A system comprising:
- a needle for insertion into a port of an implantable infusion device;
an receiver apparatus having a port location signal receiver capable of receiving a signal from the implantable infusion device regarding spatial orientation of the port;
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; and
a display operably coupled to the processor,wherein the processor is configured to cause the display to graphically render trajectory of the needle relative to the port, wherein the port is graphically rendered as a target structure having a reference area and the needle is graphically rendered as an object moveable relative to the target structure, wherein occupation of the reference area by the object indicates trajectory alignment of the port and 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.

9. A method comprising:
-
determining the orientation of a port of an implantable infusion device relative to a needle for insertion into the port; displaying trajectory of the needle relative to the port by graphically rendering the port as a target structure having a reference area and by graphically rendering the needle as an object moveable relative to the target structure, wherein occupation of the reference area by the object indicates trajectory alignment of the port and the needle. - View Dependent Claims (10, 11)

12. A 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; determine the orientation of a needle relative to the port based on the information from the transmitted signal; and graphically render trajectory of the needle relative to the port, wherein the port is graphically rendered as a target structure having a reference area and the needle is graphically rendered as an object moveable relative to the target structure, wherein occupation of the reference area by the object indicates trajectory alignment of the port and the needle.
