The PASS OCT Spinal System is intended to provide immobilization of spinal segments as an adjunct to fusion for the following acute and chronic instabilities of the craniocervical junction, the cervical spine (C1 to C7) and the thoracic spine from T1-T3: traumatic spinal fractures and/or traumatic dislocations; instability or deformity; failed previous fusions (e.g., pseudarthrosis); tumors involving the cervical spine; and degenerative disease, including intractable radiculopathy and/or myelopathy, neck and/or arm pain of discogenic origin as confirmed by radios, and degenerative disease of the facets with instability. The PASS OCT Spinal System is also intended to restore the integrity of the spinal column even in the absence of fusion for a limited time period in patients with advanced stage tumors involving the cervical spine in whom life expectancy is of insufficient duration to permit achievement of fusion.
In order to achieve additional levels of fixation, the PASS OCT Spinal System may be connected to the PASS LP Spinal System rods with the dual diameter rods or dominos. Refer to the PASS LP Spinal System package insert for a list of the PASS LP Spinal System indications of use.
The PASS OCT Spinal System is a posterior system. which consists of a variety of shapes and sizes of rods, hooks, polyaxial screws, occipital plates, occipital bone screws, and connection components, which can be rigidly locked to the rod in a variety of configurations. See package insert of the system for labeling limitations.
The implants are manufactured in titanium alloy Ti-6AI-4V ELI conforming to ISO 5832-3 specifications and ASTM F136 specifications, in PEEK OPTIMA LT1 conforming to ASTM F2026 specifications and in cobalt-chromium molybdenum alloy Co-Cr28Mo6 that conforms to ISO 5832-12 and ASTM F1537 specifications, and also CP Titanium according to ASTM F67 and ISO 5832-2 specifications.
The purpose of this 510(k) submission is to add offset connectors to the PASS OCT Spinal System.
This FDA 510(k) summary describes a spinal implant system, not an AI/ML powered device. Therefore, many of the requested elements for describing the acceptance criteria and study proving device performance are not applicable.
However, I can extract the relevant information regarding the non-clinical testing performed for this medical device.
Device Name: PASS OCT Spinal System (specifically, additional components including offset connectors)
Device Type: Spinal implant system, specifically a posterior system for immobilizing spinal segments as an adjunct to fusion.
1. Table of Acceptance Criteria and Reported Device Performance:
The document does not explicitly state quantitative acceptance criteria in a table format with corresponding reported performance for the additional components (offset connectors). However, it refers to the standard used for mechanical evaluation.
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Mechanical performance meeting requirements of ASTM F1798 (Implied: adequate strength and fatigue resistance for spinal implants) | The subject components (offset connectors) of the PASS OCT spinal system were mechanically evaluated in axial and torsional grip and dynamic flexion-extension per ASTM F1798. (This indicates the tests were performed and presumably met the standard, otherwise it would likely not be cleared.) |
| Biocompatibility requirements met (Implied: non-pyrogenic) | Pyrogenicity testing was conducted in support of PASS OCT component substantial equivalence. (This indicates the test was performed and presumably met the standard.) |
2. Sample Size Used for the Test Set and Data Provenance:
- Sample Size: Not explicitly stated in terms of number of devices tested. Mechanical testing typically involves a statistically relevant number of samples, but the exact count is not provided here.
- Data Provenance: Not applicable in the context of human data. The testing is non-clinical (bench testing), performed on the device components themselves.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:
Not applicable. This is a non-clinical, bench testing study. "Ground truth" does not apply in the context of expert consensus for interpretations as it would for imaging or diagnostic AI. The "ground truth" for mechanical testing is established by the test methods and acceptance limits defined in the ASTM F1798 standard.
4. Adjudication Method for the Test Set:
Not applicable. Adjudication methods are relevant for human interpretation tasks, not for mechanical bench testing.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:
No. This is a non-clinical bench study of a spinal implant, not an AI/ML diagnostic or assistive device for human readers.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done:
Not applicable. This is a physical medical device, not an algorithm.
7. The Type of Ground Truth Used:
For the non-clinical mechanical testing, the "ground truth" is defined by the specifications and requirements of the ASTM F1798 standard (Standard Practice for Testing Impact-Resistant Spinal Fracture Reduction Systems components in axial and torsional grip and dynamic flexion-extension). The pyrogenicity testing would adhere to established standards for biocompatibility.
8. The Sample Size for the Training Set:
Not applicable. There is no training set as this is a physical medical device, not an AI/ML algorithm.
9. How the Ground Truth for the Training Set Was Established:
Not applicable. There is no training set for this type of device.
