Iconic representations for guidance of an indwelling medical device
First Claim
1. A system for guiding and placing a catheter in a patient, the system comprising:
- a sensor designed for positioning on a chest of the patient;
a stylet designed for insertion into a lumen of the catheter; and
a console, comprising;
one or more processors;
a display communicatively coupled to the one or more processors;
a non-transitory storage device communicatively coupled to the one or more processors, the non-transitory storage device having stored thereon logic, that when executed by the one or more processors, causes performance of operations including;
depicting an icon on the display, the icon designed to indicate at least a four-dimensional position of the catheter and the stylet when the catheter and the stylet are inserted together into the patient, the icon including;
(i) a position indicator designed to indicate the position of the catheter and the stylet in a x-y plane with respect to the sensor,(ii) an orientation indicator having a first shape designed to indicate a first pitch of the catheter and the stylet, and a second shape different from the first shape to indicate a second pitch different from the first pitch, and(iii) a depth indicator designed to indicate a depth of the catheter and the stylet with respect to the sensor;
receiving updated positioning information as the catheter and the stylet are moved with respect to the sensor; and
depicting the icon in an updated state on the display according to the received updated positioning information.

Abstract
An integrated catheter placement system for accurately placing a catheter within a patient'"'"'s vasculature is disclosed. In one embodiment, the integrated system comprises a system console, a tip location sensor for temporary placement on the patient'"'"'s chest, and an ultrasound probe. The tip location sensor senses a magnetic field of a stylet disposed in a lumen of the catheter when the catheter is disposed in the vasculature. The ultrasound probe ultrasonically images a portion of the vasculature prior to introduction of the catheter. ECG signal-based catheter tip guidance is included in the integrated system to enable guidance of the catheter tip to a desired position with respect to a node of the patient'"'"'s heart. Iconic representations for depiction on the display of the system and relating to positional and other characteristics of the catheter or medical device are also disclosed.
