Intended Use

The LigaPASS is a temporary implant for use in orthopedic surgery on skeletally mature patients. The system is intended to provide temporary stabilization as a bone anchor during the development of solid bony fusion and aid in the repair of bone fractures. The indications for use include the following applications:
Spinal trauma surgery, used in sublaminar, interspinous, or facet wiring techniques; Spinal reconstructive surgery, incorporated into constructs for the purpose of correction of spinal deformities such as scoliosis, kyphosis, spondylolisthesis;
Spinal degenerative surgery, as an adjunct to spinal fusions;
The LigaPASS may also be used in conjunction with other medical implants made of titanium or chrome cobalt alloy whenever "wiring" may help secure the attachment of other implants.

Device Description

The LigaPASS connector connects a rod to a vertebra. This connector can independently tighten the rod and the bone anchor. The LigaPASS connector is composed by a connector body, a rod set screw, a locking set screw for the band and a polyester band.

AI/ML Overview

The provided text describes the LigaPASS device, a temporary orthopedic implant, and its 510(k) summary for FDA approval. It primarily focuses on demonstrating substantial equivalence to a predicate device through non-clinical testing.

Here's an analysis of the acceptance criteria and the study that proves the device meets them, based only on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria are implicitly derived from the testing standards and the comparison to predicate devices, rather than explicitly stated numerical targets. The reported performance is a qualitative statement of equivalence.

Acceptance Criteria CategorySpecific Criteria (Implicitly from ASTM Standards)Reported Device Performance
Material/DesignComparable to predicate device"substantially equivalent"
Intended UseSame as predicate device"same intended use"
Indications for UseSubstantially similar to predicate device"substantially similar indications for use"
Technological CharacteristicsSubstantially similar to predicate device"substantially similar technological characteristics"
Principles of OperationSubstantially similar to predicate device"substantially similar principles of operation"
Static Torsion PerformanceMeeting or exceeding predicate device's performance under ASTM F1717"The results of these tests indicate that the LigaPASS is equivalent to predicate devices."
Static Compression Bending PerformanceMeeting or exceeding predicate device's performance under ASTM F1717"The results of these tests indicate that the LigaPASS is equivalent to predicate devices."
Dynamic Compression Bending PerformanceMeeting or exceeding predicate device's performance under ASTM F1717"The results of these tests indicate that the LigaPASS is equivalent to predicate devices."
Static Tension PerformanceMeeting or exceeding predicate device's performance under ASTM F1798"The results of these tests indicate that the LigaPASS is equivalent to predicate devices."
Dynamic Tension PerformanceMeeting or exceeding predicate device's performance under ASTM F1798"The results of these tests indicate that the LigaPASS is equivalent to predicate devices."

2. Sample Size Used for the Test Set and Data Provenance

  • Sample Size: The document does not specify the sample size for the non-clinical tests (e.g., how many LigaPASS devices were tested for each scenario). The tests were conducted according to ASTM standards, which would typically specify minimum sample sizes, but these details are not provided in the summary.
  • Data Provenance: The tests are non-clinical, meaning they were conducted in a laboratory setting. There is no information about country of origin for the data, nor whether it was retrospective or prospective, as these terms typically apply to clinical studies involving human patients.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

Not applicable. The ground truth for this device's performance is established through physical mechanical testing against recognized industry standards (ASTM F1717 and ASTM F1798) and comparison to a legally marketed predicate device, not through expert consensus on medical images or clinical outcomes.

4. Adjudication Method for the Test Set

Not applicable, as the evaluation is based on objective mechanical testing results against standardized criteria, not human interpretation requiring adjudication.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No. The document explicitly states: "No clinical studies were performed." Therefore, no MRMC study was conducted.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done

Not applicable. This device is a physical orthopedic implant, not an algorithm or AI system.

7. The Type of Ground Truth Used

The ground truth used for this device's evaluation is primarily:

  • Mechanical Performance Data: Conformance to established ASTM standards (ASTM F1717 and ASTM F1798) for static and dynamic properties of spinal implants.
  • Substantial Equivalence to a Predicate Device: The performance and characteristics of the LigaPASS were compared to the Universal Clamp System (K060009), a legally marketed predicate device, to demonstrate that it is "substantially equivalent" in terms of safety and effectiveness.

8. The Sample Size for the Training Set

Not applicable. This device is a physical product, not an AI model requiring a training set.

9. How the Ground Truth for the Training Set Was Established

Not applicable. This device is a physical product, not an AI model.

GENERAL INFORMATION 1.

2. PREDICATE DEVICE DESCRIPTION

The Universal Clamp System is a temporary orthopedic implant intended to provide stabilization during the development of solid bony fusion and aid in the repair of bone fractures. The device system is designed to be incorporated into constructs and used in conjunction with other medical implants.

The indications for use include, but are not limited to, the following applications: Spinal trauma surgery, used in sublaminar, interspinous or facet wiring techniques; Spinal reconstructive surgery, incorporated into constructs for the purpose of spinal deformities such as scoliosis, kyphosis, spondylolisthesis, etc; spinal degenerative surgery, as an adjunct to spinal fusions.

The Universal Clamp System may also be used with other medical implants made of stainless steel whenever "wiring" may help secure the attachment of other implants.

3. DEVICE DESCRIPTION

The LigaPASS connector connects a rod to a vertebra. This connector can independently tighten the rod and the bone anchor. The LigaPASS connector is composed by a connector body, a rod set screw, a locking set screw for the band and a polyester band.

4. INTENDED USE

The LigaPASS is a temporary implant for use in orthopedic surgery on skeletally mature patients. The system is intended to provide temporary stabilization as a bone anchor during the development of solid bony fusion and aid in the repair of bone fractures. The indications for use include the following applications:

Spinal trauma surgery, used in sublaminar, interspinous, or facet wiring techniques; Spinal reconstructive surgery, incorporated into constructs for the purpose of correction of spinal deformities such as scoliosis, kyphosis, spondylolisthesis;

The LigaPASS may also be used in conjunction with other medical implants made of titanium or chrome cobalt alloy whenever "wiring" may help secure the attachment of other implants.

SUBSTANTIAL EQUIVALENCE CLAIMED TO PREDICATE DEVICES

The LigaPASS is similar to Universal Clamp System, as they have the same intended use, and substantially similar indications for use, technological characteristics and principles of operation.

NON-CLINICAL TEST SUMMARY

The following tests were conducted according to ASTM F1717 "Standard Test Methods for Spinal Implant Constructs in a Vertebrectomy Model" and ASTM F1798 "Standard Guide for Evaluating the Static and Fatique Properties of Interconnection Mechanisms and Subassemblies Used in Spinal Arthrodesis Implants":

  • Static testing in a load to failure mode in torsion 1.
  • Static testing in a load to failure mode in compression bending 2.
    1. Dynamic compression bending testing
    1. Static testing in a load to failure mode in tension
    1. Dynamic tension testing

The results of these tests indicate that the LigaPASS is equivalent to predicate devices.

CLINICAL TEST SUMMARY

No clinical studies were performed.

CONCLUSIONS: NON-CLINICAL AND CLINICAL

The LigaPASS is substantially equivalent to the predicate devices in terms of indications for use, design, material, and function.
