Medical device position guidance system with wireless connectivity between a noninvasive device and an invasive device

A medical device position guidance system comprising:

• a catheter assembly;
• and
• a noninvasive device, the noninvasive device being:
• (a) positionable over a surface of an animal;
• and (b) separate from the catheter assembly;
• and (c) configured to wirelessly communicate with the catheter assembly;
• the catheter assembly including:
• (a) a first processor;
• (b) a transmitter operatively coupled to the first processor;
• (c) a sensor operatively coupled to the first processor, the sensor being configured to, in response to a magnetic field being directed toward and reaching the sensor, output electric impulses;
• (c) a tube configured to support the sensor, the tube having an end portion configured to be inserted into an animal;
• and
• (d) a first memory device storing instructions which when executed by the first processor, cause the first processor, in cooperation with the sensor and the transmitter, to:
• (i) convert the electric impulses to a series of modulated radio waves;
• and
• (ii) wirelessly transmit, to the noninvasive device, the series of modulated radio waves;
• the noninvasive device including:
• (a) a second processor;
• (b) a magnetic field generator operatively coupled to the second processor, the magnetic field generator being configured to generate the magnetic field;
• and
• (c) a second memory device storing instructions which when executed by the second processor, cause the second processor to:
• (i) receive the wirelessly transmitted series of modulated radio waves;
• (ii) using the received wirelessly transmitted series of modulated radio waves, determine:
• (A) a distance between the noninvasive device and the end of the tube;
• and
• (B) a direction in which the end of the tube is pointing;
• and
• (iii) cause a display device to indicate the distance and the direction.
