Device Description

The proposed device, Polymer Threaded Anchor/Suture Combination, is a pre-packaged, sterile device composed of a suture anchor, anchor inserter, and non-absorbable sutures. The device is used to secure soft tissue to bone. The device is pre-packaged so that the suture is looped through the anchor eyelet and the anchor/suture is installed in the inserter. The device is single use. The device can be used for open and arthroscopic procedures. These components are packaged together 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 consists 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 its 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.

The suture used in the proposed device is a braided polyester suture. The suture is multifilament, braided, non-absorbable poly(ethylene terephthalate) surgical suture meeting USP requirements.

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:
Anchor: Polyacetal
Inserter: Piston and Sleeve: Stainless Steel, Handle: Polypropylene
Suture: multifilament, braided, non-absorbable poly(ethylene terephthalate) surgical suture from Surgical Specialties

AI/ML Overview

Here's a breakdown of the acceptance criteria and study information for the Polymer Threaded Anchor / Suture Combination, based on the provided text:

Acceptance Criteria and Device Performance

The provided document focuses on demonstrating substantial equivalence to predicate devices, primarily through mechanical testing. The acceptance criteria are implicitly defined by showing superior or equivalent performance to the predicate devices and meeting general design objectives.

Acceptance Criterion	Reported Device Performance
Pullout Strength	Proposed Device: All four proposed devices (2.8 mm, 4.0 mm, 5.0 mm, and 6.5 mm Polymer Threaded Anchors) provide higher pullout strength than the predicate ROC device (Innovasive 2.8mm and 3.5mm ROC Suture Bone Fastener). Predicate ROC device (Innovasive 2.8mm and 3.5mm ROC Suture Bone Fastener): Implicitly lower than the proposed device.
Anchor/Suture Interface (Suture Break Strength)	Proposed Device (2.8 mm Polymer OBL Anchor): Provides higher suture break strength than USP listed Knot Break Strength. Design Criteria: To create a lesser stress riser in the suture than a knot. (The 2.8mm anchor is considered the worst-case scenario due to its smallest head).
Material Equivalence	The proposed device uses Polyacetal for the anchor. This is a modification from OBL's previous "PeBA Anchor/Suture Combination" which used Titanium alloy. Innovasive's "ROC Bone Fastener" also uses Polyacetal, thereby demonstrating material equivalence to a predicate. The suture is braided polyester, meeting USP requirements and already marketed in other devices.
Design, Usage, and Function Equivalence	The proposed device is stated to be the same as the predicate "PeBA Anchor/Suture Combination" in terms of design, usage, and function, with the material change being the primary modification. Both use a threaded anchor, an eyelet for suture, and an inserter.
Sterilization Method	Both the proposed device and the Innovasive predicate device can be EtO sterilized.
Indications for Use	The device is cleared for the same indications as the PeBA Series and Cinch Series Anchor/Suture Combinations, covering various orthopedic repairs in the shoulder, hand/wrist/elbow, foot/ankle, and knee, as well as bladder neck suspension.

Study Details

2. Sample Size and Data Provenance

Sample Size for Test Set: Not explicitly stated. The text mentions "All four of the proposed devices" for pullout strength testing and "the 2.8 anchor" for suture interface testing, implying multiple tests were performed for each, but the exact number of samples per device/test is not provided.
Data Provenance: The studies were conducted internally by Orthopaedic Biosystems Ltd., Inc. (OBL) as part of their 510(k) submission. The data is retrospective in the sense that the testing was performed specifically to support the regulatory submission. The country of origin for the testing would presumably be the US, where OBL is located.

3. Number of Experts and Qualifications for Ground Truth (Test Set)

Not applicable. This is a medical device (implantable anchor/suture system, not an AI/diagnostic software) submission, and the "ground truth" for mechanical performance is established through physical testing against defined material properties and biomechanical measures (e.g., load to failure, USP standards). Expert opinion is typically not used to establish "ground truth" for such mechanical tests, though engineering expertise would be involved in designing and interpreting the tests.

4. Adjudication Method (Test Set)

Not applicable. As described above, the "ground truth" is based on direct physical measurements and comparison to established standards or predicate device performance, not on expert adjudication of diagnostic findings.

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

No, an MRMC comparative effectiveness study was not done. This type of study is relevant for diagnostic devices or AI systems where human readers interpret medical images or data. The Polymer Threaded Anchor / Suture Combination is a physical implantable device, and its effectiveness is determined by mechanical properties and clinical outcomes post-implantation, not by physician interpretation of its 'output' in a diagnostic sense.

6. Standalone Performance Study (Algorithm Only)

No, a standalone (algorithm only) performance study was not done. This is not an AI/software device. The performance refers to the biomechanical integrity of the physical device.

7. Type of Ground Truth Used

For Pullout Strength: The ground truth is the force (in lbs or another force unit) at which the anchor is liberated from the foam model. This is a direct physical measurement. The "worst case" cancellous bone model (polyurethane foam with a density of 8 lbs/cft) serves as a standardized, uniform, and challenging environment for comparison.
For Anchor/Suture Interface Strength: The ground truth is the force at which the suture breaks when tensioned through the anchor eyelet. This is a direct physical measurement. Comparison is made against USP listed Knot Break Strength, which serves as a recognized standard for suture performance.

8. Sample Size for Training Set

Not applicable. This is a physical medical device, not an AI or machine learning model that requires a training set.

9. How Ground Truth for Training Set was Established

Not applicable for the reason stated above.

DEVICE DESCRIPTION:

Overview

The proposed device is the "Polymer Threaded Anchor/Suture Combination" (K982963).

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

Changing the material of the Anchor (implant) from Titanium alloy to Polyacetal. .
The Polymer Threaded Anchor/Suture Combination uses polyacetal as the material for the anchor. Innovasive uses Polyacetal as a material in the construction of the "ROC Bone Fastener".

Device Description

The proposed device, Polymer Threaded Anchor/Suture Combination, is a pre-packaged, sterile device composed of a suture anchor, anchor inserter, and non-absorbable sutures. The device is used to secure soft tissue to bone. The device is pre-packaged so that the suture is looped through the anchor evelet and the anchor/suture is installed in the inserter. The device is single use. The device can be used for open and arthroscopic procedures. These components are packaged together sterile in double mylar/tvvek 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 drawing on page 12 for shape and dimensions of the device.

The suture used in the proposed device is a braided polyester suture. The suture is multifilament, braided, non-absorbable poly(ethylene terephthalate) surgical suture meeting USP requirements. Provided by Surgical Specialties, the suture is currently marketed through N80950 (See Appendix 2 for Approval Letters). The largest anticipated diameter of suture is USP #2. The smallest anticipated size of suture is USP #2-0.

Materials

Anchor: Polyacetal Inserter: Piston and Sleeve: Stainless Steel, Handle: Polypropylene Suture: multifilament, braided, non-absorbable poly(ethylene terephthalate) surgical suture from Surgical Specialties, see Appendix 3.

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.

COMPARISON OF CHARACTERISTICS:

OBL Polymer Threaded Anchor / Suture Combination 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 / Suture Combination 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. Both devices utilize braided polyester suture. Both devices utilize an inserter modeled after a screwdriver to turn the anchor into the implantation 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 risers 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.
