Abstract:
1. A system comprising: a needle for insertion into a port of an implantable infusion device, the port having an axis defining a target trajectory for the needle, and the needle having an axis; a receiver apparatus having a port location signal receiver capable of receiving a signal from the implantable infusion device regarding spatial orientation of the portal wherein the receiver apparatus is configured to be longitudinally fixed to the needle, relative to the axis of the needle while the needle is 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 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 actual axis of 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.
