The device description clearly states it is a "pre-packaged, sterile polyacetal implant" and describes physical components like a threaded portion, eyelet, and drive means, along with reusable insertion devices. This indicates a hardware medical device, not a software-only one.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Description and Intended Use: The description clearly states that this device is a "pre-packaged, sterile polyacetal implant" used to "secure soft tissue to bone." Its intended use is for the "fixation of non-absorbable synthetic sutures" in various anatomical locations (Shoulder, Hand, Wrist, Elbow, Foot, Knee, Pelvis).
- Mechanism of Action: The device is a physical implant that provides mechanical support for sutures within the body. It does not analyze biological samples.
Therefore, this device falls under the category of a surgical implant or fixation device, not an In Vitro Diagnostic.

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.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
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.

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.
