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.

First claim

What is claimed is:

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…
