Abstract
A system and method including a guide wire having a plurality of sensors attached near an end of the guide wire, and a processor configured to determine a position of a body component and a position of a catheter moving along the guide wire based on the signals received from the plurality of sensors. Feedback information can be generated based on these determined positions to help guide a medical procedure.
Claims7
A system for placing a prosthetic aortic valve comprising:
- a guide wire capable of being at least partially inserted into a patient, said guide wire comprising a proximate end and a distal end, said distal end being the end at least partially inserted into a patient;
- a prosthetic device removably coupled to said guide wire, said prosthetic device capable of being received within the patient;
- at least one sensor disposed along at least a portion of said guide wire disposed at or near said distal end of said guide wire;
- and
- a processor,
- wherein said at least one sensor is configured to detect contact with a body component of the patient and produce a signal relative to such contact, and
- wherein said processor is configured to receive and interpret at least one signal produced by said at least one sensor and thereby determine based on said at least one signal a position of said prosthetic device relative to said position of said body component,
- wherein said at least one signal has a substantially time-varying component and a substantially constant value, wherein said processor is configured to detect when said at least one signal exhibits a time-varying component that matches a pattern and determine said position of said body component based on said at least one signal, and
- wherein said processor generates feedback data regarding the positioning of one or more of said body component and said prosthetic device,
- wherein said processor is further configured to detect when said signal exhibits a constant value that exceeds a predetermined threshold value and determine said position of said prosthetic device based on said at least one signal.

A method for placing a prosthetic aortic valve comprising the steps of:
- inserting a guide wire through a vasculature of a patient;
- detecting, by at least one sensor disposed on the guide wire, a body component;
- determining, by a processor, a position of the body component based on at least one signal received from the at least one sensor;
- feeding a catheter along the guide wire through the vasculature;
- detecting, by the at least one sensor, a prosthetic aortic valve disposed on at least part of the catheter as the catheter is fed along the guide wire;
- determining, by the processor, a position of the prosthetic aortic valve along the guide wire based on the at least one signal received from the at least one sensor;
- and
- generating, by the processor, feedback information indicating the position of the prosthetic aortic valve relative to the position of the body component.
