The device is described as converting, storing, and transferring ultrasound video and images, and providing image management and reporting functions. It does not exert any therapeutic effect on a patient. Its purpose is to manage diagnostic information, not to treat a condition.
No
The device is primarily an imaging management system that converts, stores, and transfers ultrasound video footage. While it mentions allowing users to measure left ventricular function, its core functionality is not to diagnose conditions but to facilitate the handling of diagnostic images. The device description explicitly states it is "intended for use when there is a need to convert ultrasound analog video to a digital video format for subsequent review and archiving."
No
The device description explicitly mentions hardware components like an image acquisition unit (IAU) with internal hard disk, removable digital storage device, and optional modem or ISDN interface. While it uses proprietary software, it is not solely software.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens from the human body. The intended use and device description clearly state that the EchoLINK device is used to convert and manage ultrasound analog video from an ultrasound machine. This is image data, not biological specimens like blood, urine, or tissue.
- The purpose of IVDs is to provide information about a physiological or pathological state. While the EchoLINK device is used in the context of diagnosing heart conditions (echocardiography), its function is to handle and manage the image data generated by the ultrasound machine, not to directly analyze biological samples to provide diagnostic information.
The EchoLINK device is a medical device used for image management, archiving, and transfer in the field of echocardiography. It processes and handles image data, which falls outside the definition of an In Vitro Diagnostic device.

Device Description
EchoLINK provides a telecardiology system, a complete image management system, and a stress echo acquisition and measurement system. There are four major components that make up the EchoLINK device; an image acquisition unit, a review station, a CDR library system, and the networking components. The EchoLINK image acquisition unit (IAU) uses MPEG2 technology to convert analog video coming from the ultrasound machine to digital video in real time. The IAU can store up to 130 minutes of digital video data on its internal hard disk or 20 minutes on a removal digital storage device. The data storage format is in standard WindowsNT or DICOM 3. The IAU employs user-defined protocols for view indexing. The IAU allows for the placement of time markers within a view to identify the start and end of systole (necessary for stress echo applications) and allows the user to measure left ventricular function. The IAU is network-ready for transferring patient data to a central CDR library system and/or to a physician's review station. The EchoLINK device has an electronic report generator that allows the sonographer and physician to enter exam information as part of a paperless reporting system.
The EchoLINK device, when equipped with an optional modem or ISDN interface, can be remotely accessed to provide a variety of telecardiology solutions. The device is controlled by MPACS proprietary software.

F. Device Description
EchoLINK provides a telecardiology system, a complete image management system, and a stress echo acquisition and measurement system. There are four major components that make up the EchoLINK device; an image acquisition unit, a review station, a CDR library system, and the networking components.
The EchoLINK image acquisition unit (IAU) uses MPEG2 technology to convert analog video coming from the ultrasound machine to digital video in real time. The IAU can store up to 130 minutes of digital video data on its internal hard disk or 20 minutes on a removal digital storage device. The data storage format is in standard WindowsNT or DICOM 3.

G. Intended Use
This device is intended for use by health care professionals trained in the field of echocardiography or medical ultrasound. It is to be used when there is a need to convert ultrasound analog video to a digital video format for subsequent review and archiving. This device is also intended for use in transferring ultrasound images over digital networks and/or digital communication lines.
H. Substantial Equivalency Comparison
There are some technological differences between the EchoLINK device and the equivalent devices, however these differences do not affect the safety or effectiveness of the new device. These differences are discussed below.
With respect to routine echocardiography and image management, EchoLINK is substantially equivalent to the UNIVISION product except for the level of MPEG
2
compression used. UNIVISION uses MPEG1 compression, which limits the image size to 352x240, and only digitizes the even field within a video frame. Only digitizing one field causes a softening of the image (less defined edges). MPEG2 employs a larger image size, 352x480, which doubles the horizontal resolution of the image. MPEG2 also digitizes both the even and odd fields of the video frame for a much sharper image. Finally, EchoLINK uses MPEG2 compression for routine studies because of the current efforts by the ACR/NEMA DICOM standards committee to include MPEG2 into the DICOM standard. EchoLINK only uses MPEG1 for non-diagnostic telecardiology applications.
With respect to stress echo applications, EchoLINK is substantially equivalent to the TomTect 90 product except for the type of video compression used. EchoLINK's image acquisition unit records streaming video (continuous video segments for a duration determined by the user) as oppose to image clips for a duration set by the acquisition unit. The TomTec 90, employs the use of image clips compressed by motion JPEG technology. JPEG can only achieve usable compression ratios up to 20 to 1. Therefore, in order to limit the storage requirements, the TomTec 90 limits acquisition times to a few seconds or less per view of the heart. This technique of limiting acquisition times is called "Clinical Compression". Additionally, JPEG does not allow for the digitizing of audio, which is an important component that needs to be recorded during Doppler examinations. The MPEG2 compression technique, which is an international standard for full-motion video compression and covered under the equivalent NCI UNIVISION device (K964803), used by EchoLINK provides 55:1 compression and records full stereo sound. There is no need for clinical compression with the EchoLINK device and image acquisitions can be the same duration as previously used with VCR tape storage.
One additional minor technology difference between EchoLINK and the TomTect " is how the devices mark a particular portion of a view for display. In most stress echo protocols, only the contraction phase (systole) of the cardiac cycle is of interest. In the TomTect 00, this limit duration view is acquired by triggering acquisition off the R-wave portion of the ECG and collecting a fixed number of frames. It is critical that the sonographer selects the correct number of post-triggered frames in order to properly capture the systolic event. The number of frames selected will depend on the patient's heart rate. You need more frames when the heart is at rest than when the heart is at peak stress. Selecting an inappropriate number of frames, post R-wave, is a potential source of error. To eliminate this potential source of error. EchoLINK's image acquisition unit allows the sonographer to collect multiple cardiac cycles and then while reviewing the images place markers within the view to precisely mark the beginning and end of systole. This eliminates the trial and error approach of triggering on the R-wave and increases the effectiveness of the new device.
EchoLINK's performance is the same as the equivalent marketed devices. All three devices are required to acquire and digitize full-motion (30 frames per second) analog video in real time. Likewise all three devices can playback the stored digital video in real-time.

I. Conclusions
EchoLINK, NCI's UNIVISION, and the TomTect 90 are all used in the same way to digitally acquire, store and review ultrasound exams. All three devices interface with the ultrasound machine in a similar manner via the machine's analog video output.
There are some technological differences between the new device and the equivalent devices, however these differences do not affect the safety or effectiveness of the new device.
Based on the intended use and the comparisons between the EchoLINK device and the legally marketed devices, there are all the indications that the EchoLINK device is substantially equivalent to the NCI's UNIVISION and the TomTec"90 devices.
