Device Description

The prime function of the Horizon XVu (Cathlab) is to acquire and display vital-sign data and waveforms in real time during the catheterization process, creating a fully documented case history. The Horizon XVu system consists of a Front End unit (CFE) and a Central system. The CFE acquires, processes, and converts vital signs from the patient into digital signals and sends them to the central system for process and display. The central system contains a computer workstation, displays, printer, and other components. The system is capable of acquiring and displaying ECG/Heart Rate, ICECG, invasive blood pressures, pulse oximetry, respiration, cardiac output, and body temperature.

AI/ML Overview

The provided text describes a 510(k) submission for a modification to the Mennen Medical Horizon XVu device, specifically adding an Intra-Cardiac ECG (ICECG) measurement option. The submission focuses on demonstrating substantial equivalence to predicate devices rather than proving new clinical effectiveness. Therefore, some of the requested information, particularly related to clinical study design (sample size, expert ground truth, adjudication, MRMC studies) for new effectiveness claims, is not detailed in this type of regulatory document.

However, based on the provided text, we can extract information regarding acceptance criteria (implied by the comparison to a predicate device) and the verification/validation activities performed.

Acceptance Criteria and Reported Device Performance

The acceptance criteria for the modified Horizon XVu with ICECG (960-OPT-600) are implicitly defined by its substantial equivalence to two predicate devices:

Horizon XVu (K081484): For the overall Cathlab system functionality, ensuring that the addition of ICECG does not negatively impact existing vital sign acquisition and display.
Mennen Medical EMS-XL cardiac electrophysiology system (K071348): Specifically for the ICECG measurement capabilities, ensuring its performance is comparable to the ICECG functionality of the EMS-XL.

The device performance is reported by comparing its characteristics directly to these predicate devices.

Study Details

The provided document describes verification and validation activities rather than a traditional clinical study with a test set of patient cases. This is typical for a 510(k) modification aiming to demonstrate substantial equivalence, especially when the modification is primarily technological (adding a new parameter that leverages existing technology).

Sample size used for the test set and data provenance:
- Test set: Not applicable in the sense of a clinical patient cohort. The testing described is system-level and software validation.
- Data provenance: Not specified other than "performance tests designed to ensure that the device meets all functional requirements and performance specifications". It is implied that this testing was internal to Mennen Medical or conducted by approved testing bodies. The document does not mention data from human subjects or a clinical test set for the ICECG functionality.
Number of experts used to establish the ground truth for the test set and qualifications of those experts:
- Not applicable/Not specified. Ground truth in this context would refer to the established performance requirements of the predicate devices and industry standards. No mention of human expert adjudication for a "test set" of cases.
Adjudication method for the test set:
- Not applicable.
If a multi-reader multi-case (MRMC) comparative effectiveness study was done:
- No, an MRMC study was not done. The submission is for a device modification to add a measurement parameter, not a new diagnostic algorithm requiring comparative effectiveness against human readers.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- The document implies that the performance tests were for the device's ability to acquire and display the ICECG signal correctly, which is a "standalone" or intrinsic performance evaluation of the hardware and software. The "stand-alone" performance criteria are tied to the specifications of the predicate EMS-XL system's ICECG measurement.
The type of ground truth used:
- The ground truth for this submission is based on engineering specifications and established performance characteristics of the predicate devices (Horizon XVu and EMS-XL), as well as compliance with electrical safety and EMC standards (e.g., IEC 60601 series). The claim is that the new ICECG functionality performs equivalently to an already cleared device, and the overall system still performs equivalently to the original cleared Horizon XVu.
The sample size for the training set:
- Not applicable. This is not a submission for an AI/ML algorithm that requires a training set of data. The "software" changes relate to displaying and controlling existing vital signs and the new ICECG, implying configuration and integration rather than learning.
How the ground truth for the training set was established:
- Not applicable (as there is no training set for an AI/ML algorithm).

Traditional 510(k): Device Modification - Horizon XVu

Terminology

Subject of this 510(k) = Horizon XVu with ICECG

The Horizon XVu is a modified device, a system identical to the Horizon XVu Cathlab with the addition of Intra Cardiac ECG (ICECG) measurement.

This submission is for a modification of the Horizon XVu that Mennen Medical has received 510K clearance for marketing K081484 (see attached FDA approvals in part 21)

We intend to add to the Horizon XVu Computerized Catheterization Laboratory, ICECG measurement option usingas a predicated device the ICECG measurement of the Mennen Medical EMS-XL cardiac electrophysiology system (K071348). (See attached FDA letter Part 21)

Horizon XVu = The predicate device. The Horizon XVu Cathlab was cleared for marketing by the FDA (K081484)

EMS-XL = The predicated device for ICECG measurement. The EMX-XL was cleared for marketing by FDA (K071348)

Intended Use of the Horizon XVu

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

Device Description: Horizon XVu

The prime function of the Horizon XVu (Cathlab) is to acquire and display vital-sign data and waveforms in real time during the catheterization process, creating a fully documented case history.

Horizon XVu System (Console option) - General View

Image /page/1/Picture/3 description: The image shows a Horizon XVu Cathlab System, including the physician's remote, CFE, and CFE mounting. The system appears to be a medical imaging device used in cardiac catheterization laboratories. The image provides a visual representation of the components and setup of the Horizon XVu Cathlab System, highlighting the remote control, CFE unit, and mounting configuration.

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

Functional Description of the Horizon XVu

The Horizon XVu is capable of acquiring and displaying essential patient data such as ECG/Heart Rate, ICECG, invasive blood pressures, pulse oximetry, respiration, cardiac output, and body temperature. Heart rate, multi-lead ECG, EtCO2 and BP waveforms from different heart and vascular sites are continuously presented on the Physiological Waveform Display. The hemodynamic data, waveform and numerical, can be stored, analyzed and presented in a variety of report formats.

The Horizon XVu software includes graphic presentation of the Heart and abdominal, cranial and peripheral vascular system, to support reporting of heart and vascular catheterization.

Catheterization procedure

During a typical catheterization procedure, the physician guides a catherer to the site of interest by observing an X-ray display and the Horizon XVu Patient Data Display, and then instucts the catheterization technician at the on-line workstation to acquire pressure waveform(s) data for that site. With a single keystroke, the technician labels the site and initiates waveform/data sample acquisition.

The waveform of interest changes to a pre-defined color at the Patient Data Display during acquisition for ease of identification. Another keystroke signals the Horizon XVu to stop the acquisition and begin analysis of the newly acquired pressure information via the dedicated Workstation Horizon XVu Computer, at which time the waveform for the corresponding pressure channel will change back to one of the default colors for non-defined pressures.

The Patient Data Procedure Display provides a view of the acquired ECG and heartbeats sampled for review, editing, and acceptance via the Horizon XVu Interface. The numerical results of calculations are based on the accepted beats. These results will include such items as (for example) Systolic, Diastolic, and Mean pressure values.

The technician may at this point use the Interface to accept the displayed pressure information; doing so will store the values to the patient's on-line Procedure File.

The Horizon XVu is used for activities such as coronary and peripheral endovascular procedures and Angioplasty. The basic steps described above (catheter positioning, site definition/acquisition, analysis and acceptance) are performed as an integral part of these procedures.

The system has a computer that utilizes powerful, real-time, software to control the system operation and to process the vital patient sign data measurements acquired from the CFE or entered manually at the keyboard.

A Laser Printer is provided in the system. This provides of textual and graphical summaries of all patient data and catheterization procedures.

Main components of the Horizon XVu:

The Horizon XVu system consists of

(A) a Front End unit and (B) a Central system

The "Cathlab Patient Front End" (CFE) acquires, processes, and converts vital signs (A) from the patient into digital signals. The CFE then sends the digitized signals and data, via a network connection, to the central system of the Horizon XVu for process and display.

The CFE can acquire the following physiological signals of the patient:

· ECG the CFE acquires an ECG waveform and measures Heart Rate
· ICECG the CFE measures 6 channels of differential intra-cardiac ECG
· Blood Pressure the CFE acquires a BP waveform and measures Systole, Diastole and Mean Pressure
· Temperature the CFE measures Temperature by means of a numeric value in Cº or Fº
· SpO2 the CFE acquires and measures oxygen saturation and creates a photoplethysmographic waveform and numeric value of the oxygen saturation

ICECG - Intra-Cardiac ECG

Six channels of differential ICECG are incorporated in the CFE - Cathlab front end and displayed on the Horizon XVu.

This enables the user to use an Intra-cardiac electrode catheter and display on the Horizon XVu the ICECG simultaneously with the other vital signs displayed on the Horizon XVu.

The Heart Rate detection is via the surface ECG. The ICECG is capable of showing up to 6 waveforms, and does not have any numeric vital signs.

The addition of an ICECG constitutes a change to the HW technology of the Horizon XVu front end (CFE) and involves an addition of new SW to enable the Horizon XVu to display and control the gain and filters of each channel of the ICECG and to display the ICECG waveforms. In addition the Intended Use were changed accordingly to include the ICECG

ICECG

Mennen Medical has added to the ICECG capability, for the following reasons

Users request to add to the Horizon XVu the ICECG capability in addition to the . hemodynamic analysis.
ICECG may be useful in arrhythmia analysis .

We submit that no changes were made:

· to the control mechanism of the Horizon family products
· to the operating principle of the Horizon family products
· to the energy type of the Horizon family products

{5}------------------------------------------------

As the ICECG option is not sold sterilization is not an issue.

ICECG capability does not include the catheters, thus sterilization is not an issue.

The advantages of the Horizon XVu with 960-OPT-600 on the Horizon XVu Cathlab are: Addition of ICECG.

Computer Workstation

The computer workstation is a uni-processor system that runs the Horizon XVu program on a UNIX operating system. The workstation receives the digitized signals from the CFE via the Ethernet hub, displays real-time vital signs, analyzes, processes, and calculates the vital sign data and waveforms, cardiac status in real time during the catheteization process, creating a fully documented case history. The workstation continuously displays the vital signs waveforms and data on the local ICD displays.

The hemodynamic data, ECG and ICECG waveform and numerical, can be stored, recorded, analyzed and presented in a vanety of report formats.

Description of the design of the Horizon XVu

The Horizon XVu with 960-OPT-600 uses the same hantware and software platform as the Horizon XVu.

The functional menus were modified by adding the option to display the ICECG vital signs and waveform, without any change to the other vital sign monitoring capabilities

1. Substantial Equivalence: Horizon XVu compared to Horizon with the ICECG option

{7}------------------------------------------------

Explanation of differences

The basic amplifier specifications are the same for the EMS-XL (FDA approved) and the Horizon XVu ICECG.

The number of amplifiers is different, since the Horizon XVu is basically a hemodynamic system with limited intracardiac capabilities, while the EMS-XL is intended for full cardiac electrophysiology examinations.

The Horizon XVu has more steps in the HP and LP filters, but the full frequency response of the amplifiers is the same in the two systems.

To summarize the amplifiers of both systems have the same characteristics.

Menu Details

Technician Display

The technician display of the Horizon XVu 960-OPT-600 is identical to the Horizon XVu with the addition of control on the display of the ICECG.

The GUI control keys of the Horizon XVu 960-OPT-600 are similar to the Horizon XVu, with the addition of ICECG.

2. Horizon XVu 960-OPT-600 - similarity and Differences in Design:

Horizon XVu with ICECG 960-OPT-600 vs. Horizon XVu

The following technological and other characteristics/features apply to both the Horizon XVu and to the Horizon XVu with 960-OPT-600:

Intended for use in hospitals .
Do not change the functionality of the Cathlab system .
Isolated inputs for vital signs sensors .
ECG amplifier front end with defibrillator protection .
. Invasive BP input circuit
Non Invasive BP measurement .
Sp02 measurement �
. Selectable filters for ECG and BP
Analog output for ECG and BP ●
Doctor's display of vital signs and physiological waveforms .
Show doctor feature for diagrams from the technician screen .

The main difference between the Horizon XVu and the Horizon XVu with 960-OPT-600: On the Horizon XVu with 960-OPT-600 it is possible to display the ICECG waveform

{8}------------------------------------------------

: · ·

We submit that the addition of the 960-OPT-600 option to the Horizon XVu is limited to the addition of a new parameter - ICECG. This change does not amount to a change in the "fundamental scientific technology" of the Cathlab and does not disqualify the Horizon XVu from being the subject of a 510(k).

The SW changes of the Horizon XVu with 960-OPT-600 vs. the Horizon XVu are not related to the type, size, method of integration, and assembly of the HW components.

The following table compares the major software element and or changes done in the Horizon XVu vs. the Horizon XVu with 960-OPT-600, Cathlab:

SW Component	Horizon XVu960-800-XXX	Horizon XVu with960OPT600 ICECG

3. Conclusion of comparison of technological characteristics:

We consider the ICECG option of the Horizon XVu to be substantially Equivalent to the ICECG in the EMS-XL

We submit that any difference between the ICECG measurement of the Horizon XVu and the ICECG measurement of the EMS-XL.

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

Verification, Validation and Testing 4.

The Horizon XVu has been subject to extensive performance testing to ensure that: 1. The acquisition and display of the patient data and waveforms by the Horizon XVu with 960-OPT-600 remain the same for the predicate device Horizon XVu.

At the system level. SW Validation of the performance of the Horizon XVu with 960-OPT -600 as compared to the Horizon XVu Cathlab system, was carried out in accordance with the test plan described in the Mennen Medical Validation Test Procedure for the Horizon XVu.

{9}------------------------------------------------

The SW Test Description for the Horizon XVu with 960-OPT-600 was derived from the SW Test Description for the Horizon XVu Cathlab system, with the necessary addition of the ICECG measurements

Final testing for the Horizon XVu system included performance tests designed to ensure that the device meets all functional requirements and performance specifications, in accordance with the requirements of the Final Test Procedure for the Horizon XVu system.

Electrical Safety testing and EMC testing were performed by an independent testing laboratory (Standard Institute of Israel SII) to ensure that the device complicable industry and safety standards (attached in Part 17)

5. Proposed Labeling
