The UroTac Bone Anchor System is intended for soft tissue fixation to the pubic bone by means of bone anchors threaded with suture. The UroTac Bone Anchor System is indicated for the treatment of stress type (female) urinary incontinence resulting from urethral hypermobility.

Device Description

Consisting of: UroTac Bone Anchor Device for soft tissue to bone attachment. UroTac Bone Anchor Inserter Instrument used to insert bone anchor in desired situs.

AI/ML Overview

This looks like a 510(k) submission for a medical device called the UroTac Bone Anchor System. While it describes the device's function, materials, intended use, and comparison to predicate devices, it does not contain any information about acceptance criteria, device performance metrics, or study details such as sample sizes, expert qualifications, or ground truth establishment.

The document states: "The mean failure load of the UroTac Bone Anchor, when pulled from pubic bone, has been tested in a manner consistent with the Guidance Document for Testing Bone Anchor Devices (Draft November 1, 1993). The mean fixation strength of the device was demonstrated to be substantially equivalent to that of the Mitek predicate device."

This indicates that a non-clinical test was performed to assess fixation strength and compare it to a predicate device, but no specific numerical acceptance criteria or detailed study results are provided in this excerpt.

Therefore, I cannot fill in the requested table or answer most of the questions based on the provided text.

Here's an attempt to address what can be inferred:

Acceptance Criteria and Device Performance (Based on Inferred Information):

Acceptance Criteria	Reported Device Performance
Substantial equivalence in mean fixation strength to Mitek GII Bone Anchor.	Mean fixation strength was demonstrated to be substantially equivalent to that of the Mitek predicate device.

Detailed Study Information:

Sample size used for the test set and the data provenance: Not specified in the provided text. The testing was "non-clinical," implying laboratory or bench testing rather than human clinical trials.
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable/Not specified. "Ground truth" for a non-clinical, mechanical strength test would typically be objective physical measurements, not expert consensus.
Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable/Not specified. This is relevant for clinical studies with subjective interpretations, not mechanical testing.
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This device is a bone anchor, not an AI diagnostic tool.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is a physical medical device.
The type of ground truth used (expert consensus, pathology, outcomes data, etc): Objective, measured mechanical force (failure load/fixation strength).
The sample size for the training set: Not applicable. This is a physical device, not a machine learning model requiring a training set.
How the ground truth for the training set was established: Not applicable.

Summary of what is known from the text regarding the study:

Study Type: Non-clinical (bench/laboratory) testing.
Purpose: To demonstrate the mean fixation strength of the UroTac Bone Anchor when pulled from pubic bone.
Methodology: Conducted "in a manner consistent with the Guidance Document for Testing Bone Anchor Devices (Draft November 1, 1993)."
Comparison: Compared to the Mitek GII Bone Anchor (predicate device).
Conclusion: The device's mean fixation strength was "substantially equivalent" to that of the Mitek predicate device, and the tests "did not yield any data suggesting safety or effectiveness issues which are other than those presented by the Mitek predicate device."

UroTac Bone Anchor System NAME OF DEVICE Consisting of:
UroTac Bone Anchor TRADE NAME Device for soft tissue to bone attachment. COMMON NAME CLASSIFICATION NAME Staple, Fixation, Bone

TRADE NAME UroTac Bone Anchor Inserter Instrument used to insert bone anchor in desired situs. COMMON NAME CLASSIFICATION NAME Surgical Instrument - Staple Driver

PREDICATE DEVICE

MITEK GII Bone Anchor (and accessories) (K920213) MICROVASIVE (VESICA) Bone Anchor (K932925)

DESCRIPTION OF THE DEVICE

FUNCTION

Fixation of non-absorbable suture below bone surface for soft tissue fixation.

UroTac Bone Anchor System WDC - 65853/2 - 0292817 02

{1}------------------------------------------------

DEVICE DESIGN

Suture anchor constructed of Nitinol designed to lock into medulla of the pubic bone when pull force is applied to the suture attached to the anchor.

MATERIAL

Anchor - Nitinol Inserter - Stainless Steel (ASTM F899-94).

INTENDED USE

COMPARISON TO PREDICATE DEVICES

The predicate device is the Mitek GII Anchor. Equivalent features include: use in connection with bladder neck suspension procedure to accomplish soft tissue fixation to the pubic bone; insertion of anchor into pubic bone; use of an inserter to set the anchor into the pubic bone; use of Nitinol as an essential material; use of USP Class I suture; and initial fixation strengths that are substantially equivalent. Microvasive's Vesica Bone Anchor is a predicate device by virtue of the similarity of certain aspects of the bladder neck suspension procedure.

DESCRIPTION OF NON CLINICAL TESTS

The mean failure load of the UroTac Bone Anchor, when pulled from pubic bone, has been tested in a manner consistent with the Guidance Document for Testing Bone Anchor Devices (Draft November 1, 1993).

CONCLUSIONS FROM TESTS

The mean fixation strength of the device was demonstrated to be substantially equivalent to that of the Mitek predicate device. The tests did not yield any data suggesting safety or effectiveness issues which are other than those presented by the Mitek predicate device or the Microvasive bladder neck suspension procedure using the Vesica Bone Anchor.
