No
The device description and performance studies focus on the material properties and mechanical performance of a suture anchor, with no mention of AI or ML.
Yes
The device is intended for fixation of suture to bone in various parts of the body for repair and reconstruction procedures, which are therapeutic interventions.
No
Explanation: The device described is a suture anchor intended for fixation of suture to bone during surgical procedures. Its purpose is to physically support and secure tissue, not to diagnose medical conditions or provide information about a patient's health status.
No
The device description clearly indicates it is a physical suture anchor made of polymer and bioceramic materials, intended for surgical implantation. It also mentions reusable instruments for implantation. This is a hardware medical device.
Based on the provided information, the Acuitive CITREFIX™ Knotless Suture Anchor is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the device is for "fixation of suture to bone" in various anatomical locations during surgical procedures. This is a direct surgical intervention on the patient's body.
- Device Description: The description details a physical implantable device made of a polymer/bioceramic composite with an eyelet for suture passage. It is implanted using surgical instruments.
- Lack of IVD Characteristics: An IVD device is used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The CITREFIX device does not perform any such analysis of biological samples.
- Performance Studies: The performance studies focus on the mechanical properties of the anchor (pull-out strength, cyclic loading), biocompatibility, and shelf life – all relevant to an implantable surgical device, not an IVD.
Therefore, the Acuitive CITREFIX™ Knotless Suture Anchor is a surgical implant, not an In Vitro Diagnostic device.

Device Description
The CITREFIX Knotless Suture Anchor is comprised primarily of Acuitive Technologies' proprietary CITREGEN, citrate-based polymer / bioceramic composite material. An integral eyelet made of PEEK conforming to ASTM F2026 facilitates passage of the suture through the tip of the anchor. The CITREFIX device is offered in diameters between 2.9 and 5.5 mm and lengths ranging between 12.5 and 24.0 mm. The CITREFIX Knotless Suture Anchor is implanted with reusable instruments, which include size specific drill and awl options for preparing the bone and an insertion instrument for placement of the CITREFIX device. Suture is not provided with the CITREFIX device.
The CITREFIX Knotless Suture Anchor is made from CITREGEN biomaterial, a homogeneous biocomposite of 60 % unsintered hydroxyapatite (HA) and 40 % polyester. CITREGEN's polymer component is a citrate-based network of completely amorphous polymer chains crosslinked together to form an elastomeric material. As water penetrates the subject device, surface erosion of the polymer occurs through hydrolysis of ester bonds located between the monomers and at crosslink sites.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The performance characteristics of CITREFIX Knotless Suture Anchors were established via studies of functional performance in vitro, packaging, shelf life testing, sterility including EO residuals, physical and chemical properties per ASTM F2902 and biocompatibility per ISO 10993-1. Packaging and shelf life tests using real and accelerated time aging were performed with passing results. The labeled shelf-life of the product is one year based on the stability data analyzed to date. Bacterial endotoxin testing showed CITREFIX to meet the set endotoxin limits (
§ 888.3030 Single/multiple component metallic bone fixation appliances and accessories.
(a)
Identification. Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)

E. Device Description
The CITREFIX Knotless Suture Anchor is comprised primarily of Acuitive Technologies' proprietary CITREGEN, citrate-based polymer / bioceramic composite material. An integral eyelet made of PEEK conforming to ASTM F2026 facilitates passage of the suture through the tip of the anchor. The CITREFIX device is offered in diameters between 2.9 and 5.5 mm and lengths ranging between 12.5 and 24.0 mm. The CITREFIX Knotless Suture Anchor is implanted with reusable instruments, which include size specific drill and awl options for preparing the bone and an insertion instrument for placement of the CITREFIX device. Suture is not provided with the CITREFIX device.
The CITREFIX Knotless Suture Anchor is made from CITREGEN biomaterial, a homogeneous biocomposite of 60 % unsintered hydroxyapatite (HA) and 40 % polyester. CITREGEN's polymer component is a citrate-based network of completely amorphous polymer chains crosslinked together to form an elastomeric material. As water penetrates the subject device, surface erosion of the polymer occurs through hydrolysis of ester bonds located between the monomers and at crosslink sites.
F. Comparison of Technological Characteristics
The CITREFIX Knotless Suture Anchor has the similar intended and indications for use, as well as similar technological characteristics and principles of operation as the predicate device, and is comprised of the same CITREGEN resorbable biomaterial as the reference device (K200725). The subject Acuitive and predicate Arthrex suture anchors have similar technological characteristics that include:
- Primarily composed of resorbable biocomposite materials,
- PEEK eyelet to facilitate suture fixation to bone,
- Direct-insertion, interference fixation (push-in design), ●
- . Clinical indications and intended use.
- . Surgical technique,
- Similar drill and awl instrument options for preparing the bone, and ●
- . Provided sterile to the end user.
5
The subject device is comprised of CITREGEN biomaterial, which is a homogeneous biocomposite comprised of unsintered hydroxyapatite (HA) and polyester that is bioresorbed over time in vivo. The predicate Arthrex device is comprised of BioComposite material that is comprised of biphasic calcium phosphate and PLDLA that also resorbs in vivo. The material differences between the Acuitive device and the predicate are the polyester, bioceramic, and weight percentage of bioceramic. The specific materials used differ from the predicate but do not raise different issues of safety or effectiveness.
The minor technological differences between the subject Acuitive CITREFIX and predicate Arthrex PushLock devices do not raise new issues of safety or effectiveness. The data demonstrates that the CITREFIX is substantially equivalent to the predicate device.
G. Performance Data
The performance characteristics of CITREFIX Knotless Suture Anchors were established via studies of functional performance in vitro, packaging, shelf life testing, sterility including EO residuals, physical and chemical properties per ASTM F2902 and biocompatibility per ISO 10993-1. Packaging and shelf life tests using real and accelerated time aging were performed with passing results. The labeled shelf-life of the product is one year based on the stability data analyzed to date. Bacterial endotoxin testing showed СттеЕтх to meet the set endotoxin limits (
