The device is intended to monitor hemodynamic parameters within hospitals and other healthcare facilities providing patient care. The modified BioZ Dx device has these same intended uses.

Device Story

BioZ Dx is a noninvasive impedance cardiography (ICG) monitor; measures thoracic electrical bioimpedance via high-frequency, low-amplitude alternating current injected through sensors on neck and mid-axillary line. Device detects impedance changes over time to calculate hemodynamic parameters (e.g., stroke volume, cardiac output). Includes optional 12-lead ECG capability. Used in hospitals/healthcare facilities by trained personnel or under clinician supervision. Output displayed for clinical review to assist in hemodynamic assessment, diagnosis, and treatment decision-making. Benefits include noninvasive monitoring of cardiovascular status. Version 4.0b5 adds parameters (SVRI, LCWI, TFCI, Base Impedance, Heather Index, Q-C Interval, Stroke Index, Left Stroke Work Index) and corrects software bugs.

Clinical Evidence

Bench testing only. Quality assurance measures included risk analysis, design requirements/traceability, and unit/system-level software/firmware verification and system-level validation. Results demonstrate performance comparable to predicate devices.

Technological Characteristics

Noninvasive impedance cardiography; thoracic electrical bioimpedance sensing. High-frequency, low-amplitude alternating current. 12-lead ECG capability. Software-based hemodynamic parameter calculation. ISO 13485:2003 certified manufacturing. No hardware modifications; accessory improvements to patient sensor connector mechanism.

Indications for Use

Indicated for hemodynamic monitoring in hospital/healthcare settings for adult and pediatric patients. ICG function provides parameters including HR, SBP, DBP, MAP, SI, SV, CI, CO, SVR, SVRI, LCW, ACI, VI, TFC, Zo, TFCI, STR, STRI, PEP, LVET, TAC, TACI, LSWI, HI, QC, LCWI, SSRI, EDV, and EDI. 12-lead ECG function indicated for clinicians to evaluate ECG for diagnosis, treatment planning, treatment effectiveness, or symptom rule-out.

Regulatory Classification

Identification

An impedance plethysmograph is a device used to estimate peripheral blood flow by measuring electrical impedance changes in a region of the body such as the arms and legs.

Special Controls

## SUBSTANTIAL EQUIVALENCE:

Predicate Devices:

K051228 - CardioDynamics BioZ® Dx Hemodynamic Monitor with Philips 12-Lead ECG K011439 - CardioDynamics BioZ .com Hemodynamic Monitor (for additional parameters) K041434 - Analogic C3TM ICG Monitor (for additional parameters) K010164 - GE Medical Systems ICG Module (for additional parameters)

Device Description:

This submission covers Version 4.0b5 of the BioZ Dx System Software for the BioZ Dx (K051228), which is a noninvasive impedance cardiography (ICG) device that provides hemodynamic parameters based on the measurement of thoracic electrical bioimpedance. The BioZ Dx measures this change in impedance by injecting a high frequency, low amplitude alternating electrical current through the thorax between a pair of sensors placed on the neck and another pair placed on the mid-axillary line at the xiphoid process level. By detecting and measuring the change in thoracic impedance as a function of time, the BioZ Dx is able to calculate stroke volume, cardiac output and many other hemodynamic parameters. The device additionally includes the capability of performing a standard 12-Lead ECG test.

The modified BioZ Dx software and firmware applies the same functions and scientific concepts as the predicate devices. Additional parameters have been added in this release that exists in the predicate devices, and a small number of routine software bugs were corrected with this release.

{1}------------------------------------------------

#### Intended Use:

The BioZ Dx device is intended for use under the direct supervision of a licensed healthcare practitioner or by personnel trained in its proper use. The device is intended to monitor hemodynamic parameters within hospitals and other healthcare facilities providing patient care. The modified BioZ Dx device has these same intended uses.

Additional parameter outputs are being displayed based on calculations incorporated into predicate CardioDynamic (Systemic Vascular Resistance Index and Left Cardiac Work Index), Analogic (Thoracic Fluid Content Index, Base Impedance, Heather Index, Q-C Interval & Stroke Index) and GE (Left Stroke Work Index) devices. These additional parameter calculations use measurements and/or parameters which already existed in the BioZ Dx predicate device.

#### Technology:

The modified BioZ Dx device has the same technological characteristics as the predicate BioZ Dx device. A human factors improvement has been made to the cable and electrode accessories whereby the connections with the dual element electrode and patient leadwires have unique connector fittings to further ensure proper connections. The accessory change was determined to be insignificant (not requiring a 510(k) submission), and was documented to file and implemented into the current BioZ Dx.

#### General Safety & Effectiveness Concerns:

The instructions for use for this device contain the necessary cautions and warnings to provide for safe and effective use for the device.

Risk management is an essential element of the design and development process, and hazard analysis assessments performed on the modified BioZ Dx device at the System and Software levels revealed that the enhancements present no additional risks from the predicate devices. The software hazard analysis for the modified device in included in section 16.1 and the system hazard analysis is included in section 18.1.

CardioDynamics International Corporation is presently certified to ISO13485:2003 by Nemko. No significant audit findings have been presented since initial ISO 13485 certification in May of 1998. All products are designed and manufactured under CDIC's Quality Management System, which includes Design Control and Good Manufacturing Practices.

#### Performance Testing:

There have been no hardware modifications between the modified BioZ Dx and the predicate BioZ Dx monitor device, thus the relevant electrical safety standards have not been impacted by this product change. The improvements to the cable/electrode accessories were confined to the patient sensor connector mechanism only, and there were no impacts to the electromagnetic compatibility standards when compared to the predicate BioZ Dx device.

Design Review is required, at a minimum, at the completion of each step in the design control process (i.e. Design Input, Design Output, Design Verification, Design Validation and Design Transfer). The design review process identifies the required deliverables for each step in the process and verifies the content and accuracy of each deliverable.

{2}------------------------------------------------

The following quality assurance measures were conducted for the modified BioZ Dx device and are included in this submission:

- . Risk analysis
- . Design requirements and traceability
- . Unit and system level software and firmware verifications
- . System level validations

The results of verification and validation tests concluded that the functionality and performance characteristics of the modified BioZ Dx are comparable to the currently marketed predicate devices.

Conclusion:

The results of all testing demonstrate that the modified BioZ Dx Hemodynamic Monitor with 12-Lead ECG do not raise any new issues of safety, effectiveness or performance of the device when compare to the existing predicate devices.
