Intended Use

ENVOY is intended for use as a multiparameter physiological patient monitoring system.

The ENVOY can monitor ECG/heart rate, two invasive blood pressure channels, two temperature channels, pulse oximetry, respiration, non-invasive blood pressure and EtCO2. This effectively allows the ENVOY to monitor a wide-range of adult, pediatric and neonatal patient conditions, in many different areas of the hospital.

Functions include display of multiparameter waveforms, vital signs, alarm & status messages.

The Mennen Medical ENVOY is intended for sale as a system for monitoring and recording patient information or any in-hospital application requiring patient monitoring.

The following are examples of intended clinical applications:

  • · Critical Care Patients
  • · Cardiac Step-down/Telemetry Units
  • Emergency Departments
  • · Intra-operative (Anesthesia) Monitoring
  • · Post Anesthesia Care
Device Description

The Envoy is a multiparameter physiological patient monitor, capable of monitoring:

  • · ECG/Heart Rate
  • · invasive blood pressure
  • · non-invasive blood pressure
  • · respiration
  • · pulse oximetry
  • · two temperature channels
  • · cardiac output
  • · eTCO2

The Envoy bedside patient monitor consists of a main processing unit, a mountable color monitor, and a module rack housing the various Mennen Medical plug-in vital signs modules. The modules monitor the patient's vital signs. Up to six internal modules can be plugged into a module rack. The Envoy can accommodate two module racks. The vital sign data derived from the modules by the Envoy are presented on the monitor as waveform and numeric displays.

ENVOY vital signs modules acquire vital signs data from the patient, and display their waveforms and alarms indications on the ENVOY display unit. Vital signs and waveform information are displayed simultaneously on the ENVOY Display Unit. Up to 8 traces can be displayed at any one time.

The vital signs modules interface with readily available physiologic transducers through electrically isolated patient input connections. After amplification, the signals are digitized, analyzed and displayed. All processing and alarm determination for ECG, Respiration and Invasive Blood Pressure is made using proprietary algorithms and software based on previously marketed Mennen Medical monitoring devices tested against well known and accepted data bases that present representative examples of waveform artifact to be encountered in real case conditions. The SpO2, Non-Invasive Blood Pressure and EtCO2 Modules incorporate software and/or hardware technology developed by vendors whose products are marketed in the USA.

Information from each vital sign is presented in a separate portion of the display. Each vital sign is labeled for identification and numeric value. Displayed Vital sign information can include: Primary Vital Sign Name, Waveform, Vital Sign Numeric Value, Alarm Status Message.

Operation of the ENVOY is accomplished by interaction with front panel controls on the main processor unit. A quick-knob control allows direct interaction with displayed menus for direct parameter selection and setup. Where manual entry of alphanumeric information is required, a menu keyboard menu is display.

ENVOY is a reusable, software driven, patient monitor, intended for use as part of a physiological monitoring system in a hospital environment. As such it is not a life supporting, nor life sustaining device; nor is it implantable and therefore sterility is not a consideration.

ENVOY complies with IEC 601-1 Medical Electrical Equipment, IEC 601-2-2-27 Safety of Electrocardiographic monitoring, IEC 601-2-30 Requirements for Automatic Cycling Indirect Blood Pressure monitoring, AAMI/ANSI SP-10/A1 Electronic or Automated Sphygmomanometers, IEC 601-2-34 Requirements for Invasive Blood Pressure monitoring, AAMI/ANSI ES1 Safe Current Limits for Electromedical Apparatus, and AAMVANSI EC13, Cardiac Monitors, Heart Rate Meters and Alarms. ENVOY is not a kit, does not contain any drug or biological products and is not for prescription use.

The ECG/Resp. module is the source of all ECG data in the Envoy bedside monitor. ECG is measured using a multi-lead cable via electrodes attached to the patient's chest.

Monitoring the ECG produces a continuous waveform of cardiac electrical activity to enable an accurate assessment of a patient's current physiological condition. With the ECG module, you can use a 3, 5 6 or 10 lead electrode ECG cable set to display up to 12 selectable ECG leads in up to three channels.

The 12 Lead ECG/Resp. module is housed in the Envoy module rack, where it occupies a single slot. It includes ECG and respiration monitoring.

ENVOY Patient Monitor -- Device Modification: Special 510 (k) for 12 Lead ECG/Resp. module

Conclusion of comparison of Technological characteristics:

We consider the 12 Lead ECG/Resp. module to be substantially equivalent to the 3/5/6 Lead ECG/Resp. module and we submit that any differences between the two modules:

*fall within the scope of a Special 510(k) Device Modification *do not raise any new issues of safety and effectiveness

Testing

The 12 Lead ECG/Resp. module of the Envoy patient monitor has been subject to extensive safety and performance testing. Final testing for the system included various performance tests designed to ensure that the device meets all functional requirements and performance specifications. Safety testing and EMC testing were performed by an independent testing laboratory to ensure that the device complies to applicable industry and safety standards. The 12 Lead ECG/Resp. module of the Envoy patient monitor has also been clinically tested and evaluated in a local hospital.

Dear Mr. Kassel:

We have reviewed your Section 510(k) notification of intent to market the device referenced we nave 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 stated in the onerosare, to regarry ent date of the Medical Device Amendments, or to devices that provision in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls Cosment Act (100). Tot may) attresses, sontols provisions of the Act include requirements for annual provisions of the Frea - 11tes, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations (1 remarket rippt of ally wills) will be code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to mspottonist the GMP regulation may result in regulatory action. In addition, FDA may publish

further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4646. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639.
