The description focuses on a titanium alloy implant for anchoring suture material and bench testing of its mechanical properties. There is no mention of AI or ML.
No.
The device is a bone anchor intended for fixing surgical suture material to the pelvis, primarily for bladder neck suspension. It is a mechanical implant and while it aids in a surgical procedure, it does not directly restore, modify, or replace a physiological function in the therapeutic sense.
No.
The document describes a bone anchor used for surgical fixation of suture material, which is a therapeutic device, not a diagnostic one.
No
The device description clearly states it is a titanium alloy implant, which is a physical hardware component, not software.
Based on the provided information, the AMS Mainstay™ Urologic Bone Anchor is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly states the device is for the "fixation of surgical suture material to the pelvis for the purpose of bladder neck suspension for female urinary incontinence". This is a surgical procedure performed in vivo (within the body), not a diagnostic test performed in vitro (outside the body) on biological samples.
- Device Description: The description details a titanium alloy implant used to anchor suture material to bone. This is a physical implant, not a reagent, instrument, or system intended for the examination of specimens derived from the human body.
- Lack of IVD Characteristics: The document does not mention any aspects related to analyzing biological samples, detecting substances, or providing diagnostic information.
Therefore, the AMS Mainstay™ Urologic Bone Anchor is a surgical implant, not an IVD.
N/A
Intended Use / Indications for Use
The AMS Mainstay™ Urologic Bone Anchor is intended only for the fixation of surgical suture material to the pelvis for the purpose of bladder neck suspension for female urinary incontinence due to urethral hypermobility or intrinsic sphincter deficiency.

Device Description
The AMS Mainstay™ Urologic Bone Anchor for bladder neck suspension procedures are titanium alloy implants. They are used to anchor suture material within cortical or cancellous bone sites, thereby providing a means for firmly securing soft tissue to bone. Two (2) Mainstay™ anchors are packaged in one box.
The recommended nonabsorbable suture size for the 3.5 mm Mainstay™ anchor is up to a maximum size of #0 (USP) when using two (2) strands and up to a maximum size of #2 when using a single strand.

Summary of Performance Studies
Bench Testing: The only new test performed for the AMS Mainstay™ Urologic Bone Anchor was for the Maximum Suture to Bone Anchor Interface Break Force for Monofilament Suture. The objective of the test was to measure the maximum force required to break monofilament suture that has been attached to a bone anchor, and to compare these data to the minimum knot-pull strength requirements in the USP for the same size and class of suture. Two (2) sizes of a nonabsorbable monofilament suture were evaluated in this test.
Key Metrics
All of the sutures tested exceeded the USP recommended minimum knot-pull strength for their respective class and size of suture (non-absorbable, Class I). The average suture break force for both the #3-0 and the #2 exceeded the USP minimum recommended knot-pull strength by more than a factor of four (4).

§ 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)

VI. COMPARISON TO PREDICATE DEVICE
The AMS Mainstay™ Urologic Bone Anchor with the proposed modifications is substantially equivalent to the currently marketed Howmedica® Mainstay™ Soft Tissue Anchor.
Intended Use a.
The AMS Mainstay™ Urologic Bone Anchor with the proposed modifications has the same intended use as one of the indications cleared for the currently marketed Howmedica® Mainstay™ Soft Tissue Anchor (Bladder Neck Suspension).
b. Device Performance
The AMS Mainstay™ Urologic Bone Anchor with the proposed modifications is comparable with respect to intended use and technological characteristics to the Howmedica® Mainstay™ Soft Tissue Anchor which is in commercial distribution in the United States. American Medical Systems has provided a table on the following page which compares the similarities and differences of the devices.
Bench Testing C.
The only new test performed for the AMS Mainstay™ Urologic Bone Anchor was for the Maximum Suture to Bone Anchor Interface Break Force for Monofilament Suture.
The objective of the test was to measure the maximum force required to break monofilament suture that has been attached to a bone anchor, and to compare these data to the minimum knot-pull strength requirements in the USP for the same size and class of suture. Two (2) sizes of a nonabsorbable monofilament suture were evaluated in this test.
All of the sutures tested exceeded the USP recommended minimum knot-pull strength for their respective class and size of suture (non-absorbable, Class I). The average suture break force for both the #3-0 and the #2 exceeded the USP minimum recommended knot-pull strength by more than a factor of four (4).
In summary, American Medical Systems has provided information within the 510(k) Premarket Notification to indicate that the AMS Mainstay™ Urologic Bone Anchor with the proposed modifications is safe and effective for its intended use (Bladder Neck Suspension) as one of the indications cleared for the currently marketed Howmedica® Mainstay™ Soft Tissue Anchor. Additionally, the modified AMS Mainstay™ Urologic Bone Anchor has been shown to be comparable in terms of intended use and technological characteristics to the Howmedica® Mainstay™ Soft Tissue Anchor currently in
