The document describes a mechanical/electronic system for welding sutures to bone anchors. There is no mention of AI, ML, image processing, or data analysis that would indicate the use of such technologies. The performance studies focus on mechanical strength and biological safety, not algorithmic performance.
Yes.
The device is used in surgical procedures to secure soft tissue structures to bone anchors, which directly contributes to the treatment and repair of injuries and medical conditions.
No
The device is described as a system and kit for securing soft tissue structures to bone anchors in surgical procedures, primarily focusing on suture welding. Its purpose is to physically attach tissues, not to diagnose medical conditions or provide diagnostic information.
No
The device description explicitly states that the system consists of an "electronic control module" and a "reusable welding activator with an integral connector cable," which are hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- Device Function: The Bone Anchor System and Kit is a surgical device used to physically secure soft tissue to bone anchors during surgical procedures. It involves a welding process to attach sutures.
- Intended Use: The intended use clearly describes surgical procedures performed directly on the patient's body, not the analysis of specimens outside the body.
- Device Description: The description details components like an electronic control module, welding activator, suture welding sleeve, bone anchors, and suture, all of which are used in a surgical setting.
- Lack of IVD Characteristics: There is no mention of analyzing biological specimens, diagnostic purposes based on specimen analysis, or any components typically associated with IVD devices (reagents, analyzers, etc.).
The device is a surgical tool used for mechanical fixation within the body, which falls under the category of medical devices, but not specifically In Vitro Diagnostic devices.

Summary of Performance Studies
The 510(k) Notice for the predicate ASLS system contains summaries of both in vivo and in vitro studies which were conducted to evaluate the safety, efficacy and appropriateness of the suture welding system. These data are applicable to the Bone Anchor System because the design and components of the welding mechanism are the same as those used in the BAK, ASLS and the SWK that were previously cleared for marketing. Data were presented which demonstrate that sutures placed by means of the suture welding process exhibit "knot strength" characteristics substantially above the USP requirements for the various USP suture materials tested. These tests confirm that the polypropylene monofilament sutures placed with the ultrasonic suture welding technology are equivalent in holding strength (efficacy) to sutures placed with conventional knotting techniques.
Data presented in the original Notice for the Bone Anchor System and Kit confirm that USP size 2 polypropylene monofilament sutures secured by a weld formed with the AxvaWeld Tips exceed the USP knot strength requirements. Data were presented that demonstrate that strength requirements are met regardless of the angle of applied tension between the suture and the bone anchor stem. Suture fatigue and elongation over the functional life were evaluated in bench-test models and the welded sutures have been found to meet the suggested criteria following cyclic testing.
The safety of the suture delivery system was previously evaluated by placing both welded sutures and manually knotted sutures in the dorsal skin and in bowel tissue of New Zealand rabbits [510(k) K980988]. Positive (electrocautery contact) and negative (normal tissue) controls were used in the bowel study. In both animal models there was no histopathologic change seen at the suture implant sites where the suture was sealed with ultrasonic energy. The investigators concluded that there was no significant difference in safety of efficacy between the traditional method of suture placement and the technique which includes replacement of manual knot-tying with suture welding. The design of the AxyaWeld Sleeve also prevents the heated area of suture from coming into direct contact with tissues.

Substantial Equivalence
This submission supports the position that the Axya Bone Anchor System and Kit (BAK) which includes USP size 2 polypropylene suture (manufactured by United States Surgical or Sharpoint) and a reusable welding sleeve is substantially equivalent to the original Bone Anchor System and Kit [501(k) K992405], and to the Axya Suturing and Ligating System (ASLS) [510(k) K980988], and the Axya Suture Welding System and Kit (SWK) [510(k) K983108); and that it is appropriate for its intended application. Suture applicators and suture placement devices which may be used in both endoscopic or traditional open surgical procedures have been classified under 21 CFR 876.1500. These devices are indicated for the placement of sutures to close either traumatic or surgically produced wounds. The BAK is fabricated from materials with a substantial history of use in medical devices. Both the BAK and the predicate devices secure the suture loop with an ultrasonic weld.
The 510(k) Notice for the predicate ASLS system contains summaries of both in vivo and in vitro studies which were conducted to evaluate the safety, efficacy and appropriateness of the suture welding system. These data are applicable to the Bone Anchor System because the design and components of the welding mechanism are the same as those used in the BAK, ASLS and the SWK that were previously cleared for marketing.

The design of the AxyaWeld Sleeve also prevents the heated area of suture from coming into direct contact with tissues.
The ultrasonic energy source used to weld and secure the suture loop is the same generator used for the Automatic Suturing and Ligating System and that used for the Suture Welding System and Kit, and is similar to the energy source used in the UltraCision Harmonic Scalpel [510(k) K895252].
Because of design features of the BAK, no portion of the ultrasonic generator comes into contact with human tissues. Because of this, there is virtually no risk of causing a thermal injury to the patient. The suture material is heated and welded by friction and the weld is formed by melting and fusing the polymer. No "flux" or "welding rod" is employed and no new chemical entities are introduced or produced in the welding process.
Axya Bone Anchor System and Kit with a reusable sleeve is provided non-sterile. The suture material and bone anchors are sterilized by the original manufacturer as dictated by the type of suture included with a given product configuration. The sterility processes, the manufacturing process, and the packaging process are validated by the manufacturer.
Axya Medical, Inc. believes that the information provided establishes that similar legally marketed and pre-enactment devices have been used for the same types of clinical applications as the Axya Bone Anchor System and Kit. The materials from which the Axya device is fabricated have an established history of use in medical applications, and the specific materials used by Axya have been thoroughly tested in accordance with applicable FDA guidelines.
