The device description focuses on the mechanical properties and surgical application of a titanium screw for ligament reconstruction. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.
No
The device is a surgical implant (ligament anchor soft screw) used for mechanical fixation during ligament reconstruction, not to treat a disease or condition itself.
No
Explanation: The device is a surgical implant (ligament anchor) used for fixation during ligament reconstruction, not for diagnosing medical conditions. It serves a therapeutic purpose.
No
The device description clearly states it is a physical screw manufactured from titanium alloy, which is a hardware component.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for surgical fixation of a hamstring tendon graft during ligament reconstruction. This is a surgical procedure performed on a patient's body.
- Device Description: The device is a physical screw made of titanium alloy, designed to be implanted into bone.
- Lack of IVD Characteristics: IVD devices are used to examine specimens (like blood, urine, or tissue) outside of the body to provide information about a patient's health. The provided text does not mention any such use or interaction with biological specimens for diagnostic purposes.
The device described is a surgical implant used for mechanical support and fixation within the body.
N/A
Intended Use / Indications for Use
The Corifix Ligament Anchor Soft Screw is used for anterior cruciate ligament and posterior cruciate ligament reconstruction using hamstrings. This device may also be used for bone patellar tendon bone fixation. The soft screw provides solid fixation of the ligament without damaging grafts or the need for pre-tapping, thus avoiding damage to the hamstring grafts. The ligament anchor soft screw can be used in both the femur and tibia or in conjunction with the Corifix Ligament Anchor which is already 510k approved.

Device Description
The Corifix ligament Anchor is a headless, tapered, round threaded, cannulated screw manufactured from titanium alloy (6A1 4V) which conforms to BS 7252/3 and ASTM 136/96. The screw has a 3.5mm hex drive. The Corifix Ligament Anchor Soft Screw has a rounded thread to prevent damage to the graft, is cannulated and tapered to aid insertion, and has a 3.5mm hex drive. The Corifix Ligament Anchor Soft Screw is available in four diameters i.e 7mm, 9mm & 10 mm, for each diameter of screw four lengths of screw are available i.e. 20mm, 25mm, 30mm, & 35 mm.

§ 888.3040 Smooth or threaded metallic bone fixation fastener.
(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.

Corifix Name of Company:
The Corinium Centre Cirencester Gloucestershire GL7 1YJ England
Name of Device:
Ligament Anchor Soft Screw .
Device Description:
The Corifix ligament Anchor is a headless, tapered, round threaded, cannulated screw manufactured from titanium alloy (6A1 4V) which conforms to BS 7252/3 and ASTM 136/96. The screw has a 3.5mm hex drive.
The Ligament Anchor Soft Screw has been on the foreign (i.e. non-US) market since January 1997, since that date approximately 1,700 screws have been implanted.
Intended Use.
The screws are used in anterior cruciate ligament and posterior cruciate ligament reconstruction using hamstrings. This device may also be used for bone patellar tendon bone fixation.
The soft screw provides solid fixation of the ligament without damaging grafts or the need for pre-tapping, thus avoiding damage to the hamstring grafts.
The ligament anchor soft screw can be used in both the femur and tibia or in conjunction with the Corifix Ligament Anchor which is already 510k approved. (
Material.
The material used for the Ligament Anchor Soft Screw is Titanium Alloy 6A14V, certified to BS 7252:Pt. 3:1997 Metallic materials for surgical implants - Specification for wrought titanium 6-Aluminium 4-Vanadium alloy and ASTM F136-96 Wrought Titanium-6Aluminium-4Vanadium ELI.
Device Geometry.
The Corifix Ligament Anchor Soft Screw has a rounded thread to prevent damage to the graft, is cannulated and tapered to aid insertion, and has a 3.5mm hex drive.
Sizes
The Corifix Ligament Anchor Soft Screw is available in four diameters i.e 7mm, 9mm & 10 mm, for each diameter of screw four lengths of screw are available i.e. 20mm, 25mm, 30mm, & 35 mm.

Summary of Mechanical Testing (Further details provided on Page 14 of this dossier).
The titanium alloy 6A14V from which the Corifix Ligament Anchor Soft Screw is manufactured is tested and certified to BS 7252:Pt. 3:1997 Metallic Materials for Surgical Implant -Specification for wrought titanium 6-Aluminium 4-Vanadium alloy and ASTM F136-96 Wrought Titanium-6Aluminium-4Vanadium ELI.
Independent mechanical testing of the most popular sizes of screw determined that the maximum expected clinical loads applied to this device are 150N during walking and 450N during jogging. The fixation strength of the Corifix Ligament Anchor Soft Screw was found to be 691N.
Device to which Substantial Equivalence is Claimed and Device Specific Features
Substantial equivalence for the Corifix Ligament Anchor Soft Screw is claimed with the Smith & Nephew RCI Screw, which has been in clinical use within the USA for 5 years. (Predicate Device No. K947134).
The comparable features of the RCI Screw & Corifix Ligament Anchor Soft Screw are that both screws have a rounded thread, are cannulated, made of titanium alloy 6AI4V, have a 3.5mm hex. drive and are tapered to aid insertion. The advantage of the Corifix Ligament Anchor Soft Screw is that it is available in a range of sizes.

Device Name :- Corifix Ligament Anchor Soft Screw.
INDICATIONS FOR USE
The Corifix Ligament Anchor Soft Screw is used for anterior and posterior cruciate ligament reconstruction using hamstrings.
This technique provides reduced soft-tissue morbidity and reduced post operative pain on kneeling whilst improving the cosmetic appearance for the patient.
The hamstring surgical technique and the Corifix Ligament Anchor Soft Screw work together for fixation of a hamstring tendon graft, without bone block, to achieve anatomic aperture fixation of the hamstring tendon graft in the tibia or femur.
