APTUS® Wrist Arthrodesis Plates are indicated for wrist arthrodesis.
Device Description
The subject device includes a total of seven (7) plates are to be applied using a dorsal surgical approach, and have an anatomical design appropriate for either the left or right wrist; two (2) plates are to be applied using a volar surgical approach, and are provided in versions designed specifically for the left and right wrist. The dorsal plates have overall lengths ranging from approximately 61 mm to 116 mm, and maximum widths of 13.5 mm. The volar plates have overall lengths ranging from approximately 39 mm to 42 mm, and overall widths ranging from approximately 16 mm to 26 mm. The plates from the subject device, the primary predicate device, and the reference devices have the same technological characteristics, and have similar design characteristics, include designs for dorsal or volar surgical placement, and include screw holes to accommodate locking and nonlocking screws. The plates from the subject device, the primary predicate device, and the reference devices encompass a similar range of physical dimensions (overall width, overall length, and thickness). The subject device and the primary predicate device K112169 both include plates with similar anatomic designs for dorsal surgical placement. Similarly, the subject device and the reference device K142906 both include plates with similar anatomic designs for volar surgical placement. The plates from the subject device, K112169, K142906, and K051567 are manufactured from identical unalloyed titanium material conforming to ASTM F67. The plates from the subject device, K112169, and K 142906 are compatible exclusively with previously cleared Medartis APTUS® screws, and also are compatible with previously cleared Medartis APTUS® K-Wires. All subject device final, finished components are manufactured in the same facilities using identical materials and identical manufacturing processes as used for the previously cleared Medartis device components (K112169, K142906, and K051567) and, therefore, are substantially equivalent to these devices regarding biocompatibility. The subject device components and the Medartis device components cleared in K112169 and K142906 are packaged using the same materials, and are to be sterilized by the same methods.
More Information

No
The device description and performance studies focus on the mechanical properties and design of the plates, with no mention of AI or ML.

Yes.
The device is indicated for wrist arthrodesis, which is a surgical procedure to fuse bones in the wrist, thus providing a therapeutic benefit for conditions requiring joint stabilization.

No

Explanation: The device, APTUS® Wrist Arthrodesis Plates, is described as being used for wrist arthrodesis, which is a surgical procedure to fuse the wrist bones. The device description details its physical characteristics, materials, and surgical application (dorsal or volar approach). This indicates it is an implantable medical device used for treatment, not for diagnosing a condition.

No

The device description clearly details physical plates made of titanium, intended for surgical implantation, and discusses mechanical testing and biocompatibility, indicating it is a hardware device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is "wrist arthrodesis," which is a surgical procedure to fuse bones in the wrist. This is a direct medical intervention on the body, not a test performed on samples taken from the body.
  • Device Description: The device is described as "APTUS® Wrist Arthrodesis Plates," which are physical implants made of titanium. These are surgical implants, not reagents, instruments, or systems used to examine specimens.
  • Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing biological samples (blood, urine, tissue, etc.)
    • Detecting or measuring substances in samples
    • Providing information for diagnosis, monitoring, or screening

The device is clearly a surgical implant used to stabilize and fuse bones in the wrist. This falls under the category of a surgical device, not an in vitro diagnostic device.

Device Description

The subject device includes a total of seven (7) plates are to be applied using a dorsal surgical approach, and have an anatomical design appropriate for either the left or right wrist; two (2) plates are to be applied using a volar surgical approach, and are provided in versions designed specifically for the left and right wrist. The dorsal plates have overall lengths ranging from approximately 61 mm to 116 mm, and maximum widths of 13.5 mm. The volar plates have overall lengths ranging from approximately 39 mm to 42 mm, and overall widths ranging from approximately 16 mm to 26 mm. The differences in the Indications for Use Statement for the subject device and the reference devices K 142906 and K042355 include the additional language on the use of the reference devices (fractures and osteotomies) and specific examples of usage (K042355 and K051567). These minor differences do not impact substantial equivalence because all IFUS express equivalent intended use for internal fixation of the bones of the upper extremity.

The plates from the subject device, the primary predicate device, and the reference devices have the same technological characteristics, and have similar design characteristics, include designs for dorsal or volar surgical placement, and include screw holes to accommodate locking and nonlocking screws.

The plates from the subject device, the primary predicate device, and the reference devices encompass a similar range of physical dimensions (overall width, overall length, and thickness). The subject device and the primary predicate device K112169 both include plates with similar anatomic designs for dorsal surgical placement. Similarly, the subject device and the reference device K142906 both include plates with similar anatomic designs for volar surgical placement.

The plates from the subject device, K112169, K142906, and K051567 are manufactured from identical unalloyed titanium material conforming to ASTM F67. The plates from the subject device, K112169, and K 142906 are compatible exclusively with previously cleared Medartis APTUS® screws, and also are compatible with previously cleared Medartis APTUS® K-Wires.

All subject device final, finished components are manufactured in the same facilities using identical materials and identical manufacturing processes as used for the previously cleared Medartis device components (K112169, K142906, and K051567) and, therefore, are substantially equivalent to these devices regarding biocompatibility.

The subject device components and the Medartis device components cleared in K112169 and K142906 are packaged using the same materials, and are to be sterilized by the same methods. Any minor differences in the technological characteristics among the subject device and the devices in K112169 and K142906 do not impact safety or effectiveness.

The differences among the plates from the subject device, the primary predicate device, and the reference devices are variations in the designs of the plates (number of designs, overall dimensions, placement of screw holes), and variations in the sizes of the compatible screws. The plates and screws from the reference device K042355 are made of different materials compared to the subject device. These slight differences among the subject device and the predicate and reference devices do not impact safety or effectiveness.

The volar plates have overall lengths ranging from approximately 39 mm to 42 mm, and overall widths ranging from approximately 16 mm to 26 mm. The differences in the Indications for Use Statement for the subject device and the reference devices K 142906 and K042355 include the additional language on the use of the reference devices (fractures and osteotomies) and specific examples of usage (K042355 and K051567). These minor differences do not impact substantial equivalence because all IFUS express equivalent intended use for internal fixation of the bones of the upper extremity.

The plates from the subject device, the primary predicate device, and the reference devices have the same technological characteristics, and have similar design characteristics, include designs for dorsal or volar surgical placement, and include screw holes to accommodate locking and nonlocking screws.

The plates from the subject device, the primary predicate device, and the reference devices encompass a similar range of physical dimensions (overall width, overall length, and thickness). The subject device and the primary predicate device K112169 both include plates with similar anatomic designs for dorsal surgical placement. Similarly, the subject device and the reference device K142906 both include plates with similar anatomic designs for volar surgical placement.

The plates from the subject device, K112169, K142906, and K051567 are manufactured from identical unalloyed titanium material conforming to ASTM F67. The plates from the subject device, K112169, and K 142906 are compatible exclusively with previously cleared Medartis APTUS® screws, and also are compatible with previously cleared Medartis APTUS® K-Wires.

All subject device final, finished components are manufactured in the same facilities using identical materials and identical manufacturing processes as used for the previously cleared Medartis device components (K112169, K142906, and K051567) and, therefore, are substantially equivalent to these devices regarding biocompatibility.

The subject device components and the Medartis device components cleared in K112169 and K142906 are packaged using the same materials, and are to be sterilized by the same methods. Any minor differences in the technological characteristics among the subject device and the devices in K112169 and K142906 do not impact safety or effectiveness.

The differences among the plates from the subject device, the primary predicate device, and the reference devices are variations in the designs of the plates (number of designs, overall dimensions, placement of screw holes), and variations in the sizes of the compatible screws. The plates and screws from the reference device K042355 are made of different materials compared to the subject device. These slight differences among the subject device and the predicate and reference devices do not impact safety or effectiveness.
