Device Description

The proposed device, Polymer Threaded Anchor, is a pre-packaged, sterile polyacetal implant. The device is used to secure soft tissue to bone. The device is to be used with reusable insertion devices including a drill, tap, drill/tap combination, and inserter. Surgeons may loop suture of his/her choice through the eyelet of the anchor for the attachment of soft tissue. The device is single use. The device can be used for open and arthroscopic procedures. The anchor is packaged sterile in double mylar/tyvek pouches or formed trays.

The Polymer Threaded Anchor is a polyacetal screw designed to be screwed into a hole in bone chosen by the surgeon as a site for anchoring soft tissue to bone. The anchor constists of a threaded portion to engage bone, an eyelet to retain suture, and a drive means to couple the device to the inserter. The anchor is referred to by it's major diameter of the largest thread). The sizes included in this submission are 2.8 mm, 4.0 mm, 5.0 mm, and 6.5 mm. Please see the drawings on page 9 for shape and dimensions of the device.

The Insertion Device is a manual surgical instrument comprised of a handle and shaft. The handle is constructed from polypropylene and serves as the interface between the surgeon's hand and the device. The shaft serves the functions of transferring the torque from the surgeon's hand to the anchor.

Materials Polyacetal

Use

To implant the Anchor, the surgeon must first create an implantation site in bone. OBL supplies accessory drills, taps and drill/tap combinations to prepare these sites. The inserter is used to screw the anchor into the implantation site. After the anchor is fully seated, the inserter is removed from the implantation site, leaving the anchor in the bone and suture through the anchor. The suture can then be used to attach soft tissue.

AI/ML Overview

The Polymer Threaded Anchor is a medical device designed to secure soft tissue to bone. The acceptance criteria and the study proving the device meets these criteria are detailed below:

1. Table of Acceptance Criteria and Reported Device Performance:

Acceptance Criteria Category	Specific Acceptance Criteria	Reported Device Performance
Pullout Strength	Higher than predicate ROC device in cancellous bone model (8 lbs/cft polyurethane foam).	"All four of the proposed devices provide higher pullout strength than the predicate ROC device."
Anchor/Suture Interface	Higher suture break strength than USP listed Knot Break Strength.	"The Polymer OBL 2.8 mm Anchor provides higher suture break strength than USP listed Knot Break Strength for." (Specifically for the 2.8 mm anchor, considered the worst-case due to smallest head).

2. Sample Size Used for the Test Set and Data Provenance:

The document does not specify the exact sample size for either the pullout strength or anchor/suture interface tests. It refers to "All four of the proposed devices" for pullout strength (2.8 mm, 4.0 mm, 5.0 mm, and 6.5 mm anchors) and the "2.8 mm anchor" for interface testing, implying multiple units of each size were tested.
Data Provenance: The tests were conducted using a "cancellous bone model made from polyurethane foam." This is an in vitro (laboratory) test, not originating from a country in terms of patient data. The study is prospective in nature, as it involves testing the device under controlled conditions to gather performance data.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:

This information is not applicable to this type of performance study. The "ground truth" here is the physical measurement of pullout strength and suture break strength, determined by mechanical testing, not by expert interpretation.

4. Adjudication Method for the Test Set:

Not applicable. As the ground truth is established through objective mechanical testing, there is no need for expert adjudication. The results are quantitative measurements.

5. Multi-Reader-Multi-Case (MRMC) Comparative Effectiveness Study:

No. This is a performance study of a physical medical device (an anchor) measuring its mechanical properties. MRMC studies are typically used for diagnostic or imaging devices where human readers interpret results, and the effectiveness of AI assistance for these readers is being evaluated. This device's function does not involve human interpretation in a diagnostic context.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study:

Yes, in essence. The performance tests described (pullout strength and anchor/suture interface) assess the inherent mechanical properties of the device itself, without any human interaction or algorithm involvement during the measurement of these properties. The device's "performance" is its intrinsic mechanical behavior.

7. Type of Ground Truth Used:

Objective Mechanical Measurements: The ground truth for pullout strength was the force required to liberate the anchor from the foam model, and for the anchor/suture interface, it was the force at which the suture failed. These are direct, quantifiable physical measurements.

8. Sample Size for the Training Set:

Not applicable. This study does not involve a "training set" in the context of machine learning or AI. The device's performance is evaluated based on its physical and mechanical properties, not on learned patterns from a dataset.

9. How the Ground Truth for the Training Set Was Established:

Not applicable. No training set was used.

DEVICE:

Name of Device: Polymer Threaded Anchor Trade or Proprietary Name: Polymer Threaded Anchor Common or Usual Name: Polymer Threaded Anchor Classification Name: FASTENER, FIXATION, NONDEGRADABLE, SOFT TISSUE Class: II

PREDICATE DEVICE(S):

OBL claims that the Polymer Threaded Anchor has features substantially equivalent to two 510(k) approved devices. These include: "PeBA Anchor / Suture Combination" by Orthopaedic Biosystems Ltd., Inc. (K927236) and the "2.8 and 3.5mm ROC Suture Bone Faster" by Innovasive Devices (K963402).

DEVICE DESCRIPTION:

Overview

The proposed device is the "Polymer Threaded Anchor" (K983169).

The purpose of this submission is to obtain clearance for a polymer version of the "PeBA Anchor /Suture Combination" (K972326) forming a new device called, "Polymer Threaded Anchor". Changing the material used for the implant requires a 510(k) submission.

The predicate devices used for substantial equivalence comparisons include:

. "PeBA Anchor/Suture Combination" (K972326)
. "Innovasive 2.8 mm and 3.5 mm ROC Suture Bone Fastener" (K963402)

The Polymer Threaded Anchor is a modification of the "PeBA Anchor/Suture Combination". The proposed device is the same as the predicate device in terms of usage and function. The modifications include:

. Changing the material of the Anchor (implant) from Titanium alloy to Polyacetal.
. Marketing the anchor alone without suture or inserter

The Polymer Threaded Anchor uses polyacetal as the material for the anchor. Innovasive uses Polyacetal as a material in the construction of the "ROC Bone Fastener".

COMPARISON OF CHARACTERISTICS:

OBL Polymer Threaded Anchor vs. Innovasive 2.8mm and 3.5mm ROC Suture Bone Fastener

Both devices utilize Polyacetyl as a material in the construction of the anchor. Both devices utilize suture to join soft tissue to the anchor. Both devices can be EtO sterilized.

OBL Polymer Threaded Anchor vs. OBL PeBA Anchor / Suture Combination

Both devices follow the same method of implantation. Both anchors utilize a thread to purchase bone and provide a soft tissue fixation site. OBL offers drills, taps, and other devices for the preparation of implantation sites for both products.

PERFORMANCE DATA

Test of Pullout Strength

The anchors were implanted in a cancellous bone model made from polyurethane foam with a density of 8 lbs/cft. The anchors were pulled until they were liberated from the foam.

The foam model is considered a worst case situation. The density of foam chosen closely approximates the density of cancellous bone. Using a substrate of uniform density provides more consistent results than using bone which can vary in density and vary in cortex thickness. By testing competitor's anchors in the foam, comparisons of pullout data can be made without respect to the density of the substrate for each datum.

All four of the proposed devices provide higher pullout strength than the predicate ROC device.

Test of Anchor/Suture Interface

The threads of the anchors were fixed and suture was looped through the eyelet. The suture was tensioned until failure occurred. Because the 2.8 anchor has the smallest head of the four anchors included in this submission, it is considered the worst case.

The knot is considered the weakest point in a suture (worst case) because of the stress it creates in the suture. The suture most likely to break at the knot or the anchor evelet when loaded. A design criteria for the anchor is to create a lesser stress riser than the knot.

The Polymer OBL 2.8 mm Anchor provides higher suture break strength than USP listed Knot Break Strength for.
