Intended Use
The RIALTO™ SI Fusion System is intended for sacroiliac joint fusion for conditions including sacroiliac joint disruptions and degenerative sacroiliitis.
Device Story
RIALTO™ SI Fusion System consists of cannulated titanium alloy implants (12mm diameter, 40-60mm length) for sacroiliac joint stabilization and fusion; autograft/allograft may be used. Implantation occurs via minimally invasive approach using fluoroscopy or navigated instruments. System includes reusable stainless steel taps, drivers, and drills compatible with Medtronic IPC® POWEREASE® system or manual quick-connect handles. Navigated versions integrate with StealthStation® for stereotactic guidance relative to CT/MR models or fluoroscopy. Surgeons use these tools to prepare bone and place implants. Benefits include joint stabilization and fusion for degenerative conditions.
Clinical Evidence
Bench testing only. Mechanical verification performed per ASTM F543-13 and ASTM F2193-02 (2007). Testing included push-out, torque-to-fail, four-point bend, and shear testing. Navigation accuracy was verified for navigated instruments. Biocompatibility was established via clinical history of materials. Bacterial endotoxin testing performed per ANSI/AAMI ST72 and USP <161> confirmed compliance with the 20 EU/device limit.
Technological Characteristics
Implants: Titanium alloy. Instruments: High-grade stainless steel. Energy: Manual or powered via IPC® POWEREASE® system. Navigation: Compatible with StealthStation® stereotactic system. Standards: ASTM F543-13, ASTM F2193-02, ANSI/AAMI ST72, USP <161>.
Indications for Use
Indicated for sacroiliac joint fusion in patients with sacroiliac joint disruptions and degenerative sacroiliitis.
Regulatory Classification
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.

### V. Comparison of Technological Characteristics
The primary predicate for the RIALTO™ SI Fusion System is the predicate SI-FIX Sacroiliac Joint Fusion System K110472, S.E. 05/29/2012 (Primary Predicate).
{9}------------------------------------------------
The subject RIALTO™ SI Fusion System implants have the same or similar intended use, fundamental scientific technology, material, and indications as the following FDA cleared predicates K110472 (S.E. 05/29/2012) and K131405 (S.E. 10/16/2013).
The subject RIALTO™ SI Fusion System instruments have the same or similar intended use, fundamental scientific technology, material, and indications as the following FDA cleared predicates K111520 (S.E. 10/26/2011), K110472 (S.E. 05/29/2012), K140454 (S.E. 05/22/2014), K124004 (S.E. 03/22/2013) and K150231 ( S.E. 06/16/2015)
#### VI. Performance Data
The following performance data are provided in support of the substantial equivalence determination.
#### Biocompatibility
Identical to the primary predicate devices the implants in the subject RIALTO™ SI Fusion System are made using Titanium alloy.
The non-sterile instruments are manufactured using stainless steel and are identical to the materials used for the instruments cleared under predicate submissions.
The titanium alloy and stainless steel material used for the subject RIALTO™ SI Fusion System implants and instruments have a long clinical history of safe and effective use in similar commercially available medical devices. Therefore, no additional biocompatibility testing is required.
#### Mechanical Testing
In accordance with the Guidance for Industry and FDA Staff - Spinal System 510(k)'s, Medtronic has evaluated the subject devices to demonstrate substantial equivalence to the predicate devices.
{10}------------------------------------------------
Design verification testing for the subjectimplants was completed in accordance with
- ASTM F543-13 Standard Specification and Test Methods for Metallic Medical . Bone Screws
- ASTM F2193-02 (2007) Standard Specifications and Test Methods for . Components Used in the Surgical Fixation of the Spinal Skeletal System
The tests completed were:
- Push-Out -
- Torque—to-Fail -
- Four Point Bend -
- Shear Testing -
The verification testing on the instruments included Navigation accuracy on the instruments compatible with StealthStation™ and IPC™ Powerease™.
The subject devices met the pre-determined acceptance criteria for all tests. Therefore, design verification testing determined that the subject screws and instruments are substantially equivalent to the predicate devices.
Design validation testing was performed that demonstrated that the subject instruments performed as intended and to validate the surgical approach.
#### Non-Pyrogenicity Endotoxin Testing
The bacterial endotoxin test, also known as Limulus Amebocyte Lysate (LAL) test, was performed utilizing worst case subject RIALTO™ SI Fusion implants to verify that the subject implants meet the 20 endotoxin units (EU)/device pyrogen limit specification. Testing was successfully performed and it was confirmed that the subject implants meet the 20 EU/device testing limit for general medical devices that are implanted as outlined in ANSI/AAMI ST72, Bacterial endotoxins - Test methods, routine monitoring, and
{11}------------------------------------------------
alternatives to batch testing and USP <161>, Transfusion and Infusion Assemblies and Similar Medical Devices.
#### VII. Conclusions
Based on the test results and additional supporting information provided in this premarket notification, the subject devices demonstrated substantial equivalence to the legally marketed predicate devices.
