Abstract

A method for displaying a position of a medical device, such as a catheter, during insertion thereof into a patient. In one example embodiment, the method includes obtaining a first set of detected position data relating to a location marker, such as a permanent magnet, then determining a possible first position thereof. A first confidence level relating to a match between the first set of detected position data and a first set of predicted position data is assigned. A determination is made whether the first confidence level meets or exceeds a first threshold. If the first confidence level meets or exceeds the first threshold, a determination is then made whether the first position of the location marker is within a first detection zone. If the first position of the location marker is within the first detection zone, the first position of the location marker is displayed.

First claim

What is claimed is:

1. A method of depicting a position of a medical device that is within a patient, the method comprising:
providing the medical device including a permanent magnet;
inserting the medical device into a blood vessel;
positioning a detector having a first detection zone and a second detection zone such that at least the first detection zone includes a portion of the blood vessel into which the medical device is inserted;
obtaining, via the detector, first mea…
