Indications for Use

The BMP MCG CS-MAG II Magnetocardiograph is intended for use as tool which non-invasively measures and displays the magnetic signals produced by the electric currents in the heart.

Device Story

CS-MAG II is a magnetocardiograph (MCG) system used in adult cardiology. It non-invasively records biomagnetic signals generated by cardiac ionic currents. System components include SQUID gradiometers, Dewar, electronics, gantry, and bed. SQUID sensors detect weak magnetic fields; electronics perform signal filtering (high pass, low pass, notch) and amplification. Software controls system operation, signal processing, and analysis, specifically generating 2D current maps. The device provides clinicians with visual representations of cardiac magnetic activity, aiding diagnostic assessment. Unlike traditional ECG, MCG offers increased sensitivity to weak signals and avoids distortion from body tissue conductivity. It is a non-contact, radiation-free diagnostic tool.

Clinical Evidence

Bench testing only. Testing included verification of SQUID gradiometer sensitivity (>3.5 fTrms/yHz), Dewar liquid capacity and boil-off rates (>7 days), electronic filter performance (high/low pass, notch), and inspection of gantry/bed mechanical specifications. Software functionality for system control, display, and 2D current map generation was verified.

Technological Characteristics

System utilizes SQUID (Superconducting Quantum Interference Device) gradiometers for magnetic field detection. Includes Dewar for cryogenic cooling, signal processing electronics (analog filtering), and mechanical gantry/bed assembly. Software performs signal analysis and 2D current mapping. Non-invasive, non-contact, radiation-free operation.

Indications for Use

Indicated for use in adult cardiology as a non-invasive tool to measure and display magnetic signals produced by cardiac electric currents.

Regulatory Classification

Identification

An electrocardiograph is a device used to process the electrical signal transmitted through two or more electrocardiograph electrodes and to produce a visual display of the electrical signal produced by the heart.

CMI Magnetocardiograph CardioMag Imaging, Inc. K033488

The Biomagnetik Park CS-MAG II Magnetocardiograph is considered substantial equivalent to the CMI Magnetocardiograph. There is no significant difference in intended use or technology.

#### Device Description: .

The BMP MCG CS-MAG II system will be used for diagnostic purposes in adult cardiology. Magnetocardiography (MCG) is a non-invasive, non-contact, radiation-free, multichannel body surface mapping technique to record biomagnetic signals from the heart generated by the same ionic currents underling the electrocardiogram. Compared to electrocardiography (ECG), MCG has similar morphological features such as T-, P-, and Q-waves, and the QRS complex. The advantages of MCGs over traditional ECGs are increased sensitivity to weak signals, lack of distortion from conductivity in body tissues, and presentation of direct current (DC) component signals and primary currents.

#### Intended Use:

The BMP MCG CS-MAG II Magnetocardiograph is intended for use as tool which non-invasively measures and displays the magnetic signals produced by the electric currents in the heart.

#### Summary of performed tests to support device claims

The MCG system test included the system and each component to support the device's claims: SQUID gradiometer, Insert, Dewar, Electronics, Software, Gantry and Bed by inspection form for each component, The SQUID gradiometer was tested especially for sensitivity better than 3.5 fTrms/yHz at white frequency to get clear signal from the magnetic field to voltage. The Dewar was tested with minimal liquid capacity and boil-off rate to get refill interval longer than 7 days. The electronics were tested for "analog filter: high pass, low pass, notch" and output amplifier and automatic control of SQUID sensors. The Software was tested for controlling system, display, signal processing and analysis especially for 2D current map. Gantry and Bed were tested by inspection of their specification - Gantry movement, Bed movement and Bed alignment.

#### Conclusion:

Biomagnetik Park GmbH believes that the MCG CS-MAG II magnetocardiograph is substantially equivalent to the currently legally marketed device. It does not introduce new indications for use, has the same technological characteristics and does not introduce new potential hazards or safety risks.

#### Dear Mr. Burmester:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you; however, that device labeling must be truthful and not misleading.
