The Siemens Acuson X300 ultrasound imaging system is intended for the following applications: General Radiology, Fetal, Abdominal, Intraoperative, Pediatric, Small Parts, Neonatal/Adult Cephalic, Cardiac, Transesophageal, Pelvic, Transcranial, OB/GYN, Urology, Vascular, Musculoskeletal, Superficial Musculoskeletal, and Peripheral Vascular applications.
The system also provides for the measurement of anatomical structures and for analysis packages that provide information that is used for clinical diagnosis purposes.
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 state of their cardiovascular system. This feature should be utilized according to the "ASE Consensus Statement; Use of Carotid Ultrasound to Identify Subclinical Vascular Disease and Evaluate Cardiovascular Disease Risk: A Consensus Statement from the American Association of Echocardiography; Carotid Intima-Media Thickness Task Force, Endorsed by the Society for Vascular Imaging".
The Acuson X300 has been designed to meet the following product safety standards:
- UL 60601-1, Safety Requirements for Medical Equipment
- IEC 60601-2-37 Diagnostic Ultrasound Safety Standards
- CSA C22.2 No. 601-1, Safety Requirements for Medical Equipment
- AIUM/NEMA UD-3, Standard for Real Time Display of Thermal and Mechanical Acoustic Output Indices on Diagnostic Ultrasound Equipment
- AIUM/NEMA UD-2, Acoustic Output Measurement Standard for Diagnostic Ultrasound
- 93/42/EEC Medical Devices Directive
- Safety and EMC Requirements for Medical Equipment
- EN/IEC 60601-1
- EN/IEC 60601-1-1
- EN/IEC 60601-1-2
- EN/IEC 60601-1-4
- EN/IEC 60601-1-6
- EN/IEC 60601-2-18
- EN/IEC 60601-2-25
- IEC 1157 Declaration of Acoustic Power
- ISO 10993-1 Biocompatibility
The provided 510(k) submission for the Siemens ACUSON X300 Diagnostic Ultrasound System does not contain specific acceptance criteria or details of a study proving the device meets acceptance criteria in the typical format of a clinical performance study with quantitative metrics (like sensitivity, specificity, or AUC) compared against a predefined threshold.
Instead, the submission primarily focuses on establishing substantial equivalence to legally marketed predicate devices, which is the primary pathway for 510(k) clearance. Substantial equivalence is demonstrated by showing that the new device has the same intended use and similar technological characteristics to the predicate device, or if there are differences, that these differences do not raise new questions of safety and effectiveness.
The "Performance Data" section (Section E) states: "The Acuson X300 modifications are verified and validated according to the company's design control process." This indicates that internal testing and verification/validation activities were performed to ensure the device functions as intended and meets its design specifications, but specific details of these tests, including acceptance criteria, sample sizes, ground truth establishment, or expert involvement, are not provided in this summary.
The document lists various product safety and biocompatibility standards that the device has been designed to meet. These standards themselves include acceptance criteria for their respective domains (e.g., electrical safety, acoustic output, biocompatibility). Compliance with these standards is a form of meeting acceptance criteria but doesn't involve clinical performance metrics in the way a comparative effectiveness study would.
The "Indications for Use Form" for the main system and each transducer lists the clinical applications and modes of operation ("P" for previously cleared, "N" for new indication). For the new indications, the assumption is that the new functionalities (like the Arterial Health Package) have been validated, but the details of this validation are not present in this document.
Therefore, based on the provided text, a table of acceptance criteria and reported device performance, sample sizes for test/training sets, expert qualifications, adjudication methods, details of MRMC studies, or standalone algorithm performance, as requested in the input, cannot be extracted.
The document describes the intended use of the device for various applications and mentions the Arterial Health Package (AHP) software, which provides capabilities to measure Intima Media Thickness and reference normative tables "validated and published in peer-reviewed studies." This implies that the underlying science for AHP's clinical utility is derived from external, peer-reviewed research, rather than a de novo clinical study conducted for this specific 510(k) submission.
Summary of available information related to performance/validation:
- Acceptance Criteria & Device Performance: Not explicitly stated as quantitative metrics against a specific threshold in this summary. The general acceptance criterion for a 510(k) is "substantial equivalence" to predicate devices, which implies similar safety and effectiveness.
- Study Type: No specific clinical study is described in detail for performance evaluation of the ACUSON X300 or its specific new features (beyond stating "modifications are verified and validated according to the company's design control process"). The AHP software references "normative tables that have been validated and published in peer-reviewed studies," indicating reliance on existing scientific literature for its clinical basis, not a new study.
- Sample Size (Test Set & Training Set): Not provided.
- Data Provenance: Not provided.
- Number of Experts/Qualifications (Test Set Ground Truth): Not provided.
- Adjudication Method: Not provided.
- Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study: No such study is mentioned.
- Standalone Performance (Algorithm Only): Not mentioned, as this is an ultrasound system with associated software, not typically a standalone AI algorithm.
- Type of Ground Truth: Not specified for any performance evaluation in this summary. For AHP, the ground truth for normative tables is implicitly from "peer-reviewed studies."
- How Ground Truth for Training Set was Established: Not applicable as training set details are not provided.
§ 870.1200 Diagnostic intravascular catheter.
(a)
Identification. An intravascular diagnostic catheter is a device used to record intracardiac pressures, to sample blood, and to introduce substances into the heart and vessels. Included in this generic device are right-heart catheters, left-heart catheters, and angiographic catheters, among others.(b)
Classification. Class II (performance standards).
