The SandShark Injectable Anchor (SIA) System is intended to be an accessory to the stimulator component of the Stimwave Freedom Spinal Cord Stimulator (SCS) System to secure the stimulator to the fascia or interspinous/supra-spinous ligament.

Device Description

The Stimwave Technologies Incorporated (Stimwave) SandShark Injectable Anchor (SIA) System is used to fixate the Stimwave Freedom Stimulator to surrounding tissue. The System is comprised of a carbothane anchor (SandShark Anchor) that is transferred onto the deployment handle (SandShark Injectroducer) with the Loading Rod and Loading Base. The SIA System is provided sterile. The SandShark Injectroducer is used to deploy the SandShark Anchor onto the Stimulator.

AI/ML Overview

The provided text describes the Stimwave SandShark Injectable Anchor (SIA) System and its substantial equivalence to predicate devices, but it does not contain information about specific acceptance criteria or a study proving that the device meets those criteria with numerical performance values relevant to AI/ML devices.

The document is a 510(k) summary for a medical device (an anchor system for spinal cord stimulators), not an AI/ML device. Therefore, the questions related to AI/ML performance metrics, sample sizes for AI/ML models, expert ground truth adjudication, MRMC studies, and standalone AI performance are not applicable to the content of this document.

The document focuses on demonstrating substantial equivalence to predicate devices through:

Intended Use and Technological Characteristics Comparison: Showing that the SIA System has the same intended use and similar technological characteristics as existing legally marketed devices.
Biocompatibility Data: Confirming that the materials meet biological safety and compatibility requirements (ISO 10993-1:2009).
Non-Clinical Performance Data: Verifying that the device meets system design requirements and applicable voluntary standards for physical performance (e.g., protection from temperature change, atmospheric pressure change as per AAMI ANSI ISO 14708-3:2008).

Since the device is not an AI/ML system, the requested information in the prompt, which is tailored for AI/ML device evaluations (e.g., sensitivity, specificity, expert ground truth, training/test sets, etc.), cannot be extracted from this document.

Therefore, I am unable to provide a table of acceptance criteria and reported device performance, or details about studies proving device performance with respect to AI/ML metrics, as this information is not present in the provided text.

Dear Elizabeth Greene:

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, 1976, 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

8. Biocompatibility Data

The materials, construction and intended use of the SIA System is comparable to the predicate device, and have a long history of safety with respect to biocompatibility. The biological safety of the SandShark Anchor was evaluated in accordance to ISO 10993-1:2009, guidance document Use of International Standard ISO 10993-1, Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process and Blue Book Memorandum G95-1 Use of International Standard ISO-10993, and Biological Evaluation of Medical Devices: Part 1: Evaluation and Testing. Under these, for the stated indications for use, the device was classified as a (C), implant device in contact with tissue/bone. The results for the biocompatible testing for cytotoxicity. sensitization, irritation or intracutaneous reactivity, acute systemic toxicity, implantation (4, 8, and 13 weeks), subacute and subchronic toxicity, chronic toxicity, carcinogenicity, extractables and leechables demonstrated no negative impacts from the materials that are used in the SIA System. The SIA System meets biological safety and compatibility requirements of ISO 10993-1:2009 and Blue Book Memorandum G95-1.

9. Non-Clinical Performance Data

The SIA System was tested to verify that the performance meets the system design requirements as well as all applicable voluntary standards. The SIA System complies with all design requirements and applicable voluntary standards.

AAMI ANSI ISO 14708-3:2008 - For protection from temperature change including shipping and storage temperature ranges, the SIA System was functional, receiving a safe rating following post visual inspection and passed the change of temperature testing performed as specified by AAMI ANSI ISO 14708-3:2008. For atmospheric pressure change, the SIA System was functional following post testing functionality inspection and passed atmospheric pressure change testing as specified by AAMI ANSI ISO 14708-3:2008.

Stimwave Technologies Incorporated Traditional 510(k) Premarket Submission SandShark Injectable Anchor (SIA) System

Stimwave completed a number of tests for the SIA System that demonstrates substantial equivalence to the legally marketed predicate devices. The SIA System meets all the requirements for overall design, sterilization, and biocompatibility confirms that the output meets the design inputs and specifications. The SIA System passed all testing stated above as shown by the acceptable results obtained.

10. Clinical Performance Data

There was no clinical testing required to support the medical device, as the indications for use are equivalent to the legally marketed predicate devices. These types of devices, including the legally marketed predicate devices, have been on the market for many years with a proven safety and efficacy for the use of the device. The non-clinical testing detailed in this submission supports the substantial equivalence of the device.

11. Statement of Substantial Equivalence

By definition, a device is substantially equivalent to legally marketed predicate devices when the device has the same intended use and the same technological characteristics as the previously cleared predicate device. The SIA System has the same intended use as the legally marketed predicates devices. Performance tested verified that the SIA System complies with all applicable voluntary standards such as AAMI ANSI ISO 14708-3. The SIA System also meets the design requirements where no applicable standard could be used. This included anchor durability testing, as well as biocompatibility and sterilization validation of the SIA System. There were no recognized performance standards for this device. There was no clinical testing performed on this device since performance testing demonstrated similar performance as the legally marketed predicate devices, and materials for the SIA System are the same as the legally marketed predicate devices.

It has been shown in this 510(k) submission that the difference between the SIA System and the legally marketed predicate devices do not raise any questions regarding its safety and effectiveness as compared to legally marketed predicate devices. The SIA System, as designed and manufactured, is determined to be substantially equivalent to the referenced legally marketed predicate devices.
