Device and a method for providing resuscitation or suspended state in cardiac arrest

1. A device for providing resuscitation or suspended state through redistribution of cardiac output to increase supply to the brain and heart for a patient, the device comprising

an electrically or manually controllable redistribution component attachable to the patient and being configured to interact with the patient to provide redistribution of the cardiac output to increase supply to the brain and heart, the redistribution component following a predefined reaction pattern based on an electrical signal, and

computer means configured to:

receive a patient data which identifies physiological and/or anatomical characteristics of the patient; and

provide the electrical signal for controlling the redistribution component and/or for presenting the physiological and/or anatomical characteristics for a user based on the patient data or a standard response,

a patient data generation means configured to generate the patient data during external cardiac compression carried out on the patient,

wherein

the computer means comprises memory means having stored therein a predefined definition of the electrical signal as a response to the patient data, and

the patient data generation means is configured to sense biosignals from a blood vessel or a tissue compartment, and

the redistribution component comprises or consists of an aortic perfusion pump, and

the device further comprises a location safety mechanism comprising at least one first sensor capable of determining a biosignal which is characteristic for aorta of the patient and an electronic circuit configured to verify a position of the aortic perfusion pump in the aorta based on the biosignal determined by the first sensor.

2. The device according to claim 1 , where the at least one first sensor comprises a pressure sensor.

3. The device according to claim 1 , where the first sensor is located on the redistribution component to determine the biosignal in a position distal to the aortic perfusion pump.

4. The device according to claim 1 , where the device is configured to use data from the first sensor in combination with data from sensors located at other locations.

5. The device according to claim 1 , where the patient data includes parameters selected from the group consisting of: aortic blood pressure, aortic blood flow, duration of cardiac arrest, expiratory CO 2 , ECG, blood pressure, compression rate and depth, pulse, respiratory frequency, cardiac output redistribution degree, aortic O 2 saturation or concentration, cerebral or peripheral saturation, temperature, fluid administered, pharmaceuticals administered, biochemical data, and ultrasound imaging.

6. The device according to claim 1 , where the computer means is configured to receive input data from the redistribution component.

7. A method for providing resuscitation or suspended state in a human cardiac arrest patient, said method comprising subjecting the patient to heart massage (chest compression) while at the same time ensuring redistribution of the cardiac output to preferentially supply blood to the brain and the heart, wherein

said redistribution is accomplished by occlusion of the aorta caudal to the left subclavian artery;

said chest compression is manual or accomplished by the use of a mechanical chest compression device

wherein occlusion is accomplished by introducing a device according to claim 1 into the aorta, and subsequently decreasing or interrupting the blood flow distal to the redistribution component by expanding the redistribution component of said device

which acts during or as a bridge to one or more of angioplasty, including PCI and angiography; ventricular assist devices; heart transplantation, including artificial heart transplantation; CABG surgery and valve surgery; placement of external or internal pacemaker or ICD; ECMO; ECLS; and cardiopulmonary bypass.

8. The method according to claim 7 , wherein the redistribution is temporarily interrupted at regular or irregular intervals so as to ensure sufficient perfusion of all parts of the body of the patient.

9. The method according to claim 7 , wherein the device is introduced into the aorta via the femoral artery.
