1.7 Comparison of Technological Characteristics with Predicate Device
| Item of Comparison | Description/Rationale |
|---|---|
| Similarities | |
| Device Design | - The hardware design of the subject device is the same as that of the predicate device.- device design of added Edwards Lifesciences external measurement devices composed of the FloTrac Pressure Cable-Philips and FloTrac sensor is equivalent to their predicate devices- Subject and predicate device run on IntelliVue Software (version R.00.), which is also the software platform available in the predicate device (version P.01.). |
| Energy Source | - Subject device is powered by AC mains or from built-in battery, as the predicate device.- Subject and predicate device do not deliver energy to patients- added external Edwards Lifesciences devices do not have their own power supply; it is supplied by the host monitor. This is the same as for their predicate devices |
| Software/Hardware Features | - Proposed modification does not introduce any new technological hardware features.- Measurements offered by the subject device are also offered by the predicate device. Subject and predicate devices have the same interfaces.- Software features introduced for the proposed IntelliVue Software version R.00.01, rely on a well-established software platform and architecture which was iteratively developed from the version available in the predicate device.- Hardware and Software of the added external Edwards Lifesciences devices are equivalent to their predicates- measurements of physiological parameters are the same as in the predicate devices |
