AI/ML (Artificial Intelligence / Machine Learning)

No
The summary does not mention AI, ML, or any related terms, and the described functionalities are typical of standard ultrasound systems.

Therapeutic

No
The device is used for diagnostic imaging and measurement of anatomical structures, not for treatment or therapy.

Diagnostic

Yes
The "Device Description" explicitly states, "The ACUSON NX2 / ACUSON NX2 Elite Diagnostic Ultrasound Systems are multi-purpose mobile, software controlled, diagnostic ultrasound systems." The "Intended Use / Indications for Use" section also notes that analysis packages provide information used for "clinical diagnosis purposes."

SaMD (Software as a Medical Device)

No

The device description explicitly states it is a "multi-purpose mobile, software controlled, diagnostic ultrasound system" and details its hardware components like the on-screen display and its function to acquire ultrasound echo data. This indicates it is a hardware system with integrated software, not a software-only device.

IVD (In Vitro Diagnostic)

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

Intended Use: The intended use clearly states that the system is for ultrasound imaging and provides measurements and analysis packages for clinical diagnosis purposes. While it aids in diagnosis, it does so by visualizing internal structures and providing measurements, not by analyzing samples taken from the body (in vitro).
Device Description: The device description details the ultrasound imaging modes and display capabilities. It focuses on acquiring and displaying ultrasound echo data.
Lack of IVD Characteristics: An IVD device typically involves the examination of specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not perform such analysis on biological samples.

The device is a diagnostic imaging system that uses ultrasound technology to visualize internal anatomy and provide measurements to assist physicians in making a diagnosis. This falls under the category of medical imaging devices, not in vitro diagnostics.

Overview

Intended Use / Indications for Use

The ACUSON NX2 and ACUSON NX2 Elite ultrasound imaging systems are intended for the following applications Cardiac. Fetal. Abdominal (including liver), Pediatric, Small Organ), Adult Cephalic, Transcranial, OBA GYN, Pelvic, Urology, Vascular (including Peripheral Vessel) and Musculoskeletal applications,

The systems also provide for the measurement of anatomical structures and for analysis packages that provide information that is used for clinical diagnosis purposes.

Ultrasound is used as an imaging aid, but may have further restrictions specific to in-vitro fertilization (IVF), choronic villus sampling (CVS), and percutaneous umbilical cord blood sampling (PUBS) procedures. Observe local laws and regulations.

The Arterial Health Package (AHP) software provides the physician with the capability to measure Intima Media Thickness and the option to reference normative tables that have been validated and published in peer-reviewed studies The information is intended to provide the physician with an easily understood tool for communicating with patients regarding the state of their cardiovascular system.
