Abstract
So as to be able to determine the position of a functional element as precisely as possible during the invasive use of a blood pump in a patient's body without the use of imaging methods, the blood pump is connected to a main sensor which records signals of the patient's heart, which are compared to other electrophysiological heart signals recorded by several sensors distributed on the body surface so as to allow the position of the blood pump to be determined by way of linking.
Claims13
A method of determining a position of a blood pump in a body of a patient, the method comprising:
- inserting the blood pump into a heart of the patient, the blood pump having a housing, wherein the housing surrounds a rotor;
- actuating the rotor;
- detecting, at one or more auxiliary sensors, a first signal, wherein the first signal represents electrophysiological signals of the heart of the patient;
- detecting, at a main sensor having a fixed distance from the blood pump, a second signal, wherein the second signal is indicative of blood pressure values of the heart of the patient;
- receiving, at a processing unit, the first signal;
- receiving, at the processing unit, the second signal, wherein the second signal is received at the processing unit after the first signal, wherein the receipt, at the processing unit, of the second signal after the first signal is indicative of a migration velocity of the second signal;
- comparing, at the processing unit, the first signal and the second signal;
- determining, at the processing unit, based on the comparing, a position variable representative of the position of the blood pump in the body of the patient;
- and
- determining, from the position variable, the position of the blood pump in the body of the patient.
