Intended Use

The Smith & Nephew CDS System is intended to dispense and monitor the pressure of fluids during spinal procedures such as discography.

Device Description

The Smith & Nephew CDS System consists of a control unit with a fluid delivery module with user interface, a remote control and a sterile, single-use fluid delivery syringe, tube set and remote sleeve.

AI/ML Overview

The provided text is a 510(k) summary for the Smith & Nephew CDS System. This document focuses on demonstrating substantial equivalence to an existing predicate device, rather than proving the device meets specific acceptance criteria through a clinical study.

Therefore, the information requested in the prompt, such as acceptance criteria, detailed study results, sample sizes for test and training sets, expert qualifications, and ground truth establishment, is not available within the provided text.

Here's why and what can be inferred:

  • Acceptance Criteria and Reported Device Performance: This information is typically found in dedicated verification and validation reports or clinical study summaries. The 510(k) summary states that "The proposed CDS System remote control underwent firmware and hardware modifications to improve its performance and reliability," and that "The changes made to the proposed CDS System represent improvements that will improve its performance over the predicate CDS System (K051136)." However, specific quantifiable performance metrics and acceptance thresholds are not provided.
  • Sample Sizes and Data Provenance: The document makes no mention of a test set, training set, or any clinical data collection. It discusses modifications to an existing device.
  • Experts, Adjudication, Ground Truth: These concepts are relevant to studies where human interpretation or a gold standard is used to validate a device's performance, especially for diagnostic or analytical devices. This document is for a fluid dispensing/monitoring system, and such detailed validation is not presented here.
  • MRMC Comparative Effectiveness Study: There is no indication of an MRMC study. The comparison is primarily against a predicate device based on technological characteristics and intended use.
  • Standalone Performance: The document does not describe a standalone performance study in the context of diagnostic accuracy (e.g., sensitivity, specificity). The "performance" mentioned refers to the functional improvements of the system's components (firmware, hardware).
  • Type of Ground Truth: Not applicable, as detailed performance data based on a defined ground truth is not provided.
  • Training Set Sample Size and Ground Truth for Training: Not applicable, as no training set for an AI/algorithm-based device is mentioned.

In summary, the provided document is a regulatory submission focused on demonstrating substantial equivalence of a modified medical device to a predicate device, rather than a detailed report of a study proving the device meets specific acceptance criteria with performance metrics, sample sizes, and ground truth information.

Dear Mr. Robbins:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1796, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

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

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Center for Devices and Radiological Health's (CDRH's) Office of Compliance at one of the following numbers, based on the regulation number at the top of this letter.
