The Ti-TaMED Spinal System is intended for immobilization and stabilization of the spine as an adjunct to fusion for use in anterior, anterolateral, or posterior non-cervical pedicle and non-pedicle fixation for spinal conditions in skeletally mature patients with significant mechanical instability or deformity requiring fusion of the thoracic, lumbar or sacral spine secondary to the following conditions: Degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra, degenerative spondylolisthesis with objective evidence of neurological impairment, fracture, dislocation, spinal stenosis, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudoarthrosis).
The Ti-TaMED Spinal System consists of a variety of rods, hooks, screws, cross connectors and other connecting components used to build a spinal construct. Instrumentation is also available to facilitate implantation of the device components. The System consists of four types of screws all manufactured out of Titanium (6A 1-4V ELI). 1. Poly Axial Screws: These screws have a poly axial articulation that allows angulations of the head in all directions, but once the cap or grub screw and ring are tightened the position becomes locked. 2. Rigid screws. The Ti-TaMED Spinal system consists of two different types of rods: Round both ends and Round and hexagonal ends. The Ti-TaMED Spinal system also consists of the following: Cross Connector and Hooks. The Ti-TaMED screws and rods may be used posteriorly or anteriorly to help provide immobilization and stabilization of spinal segments as an adjunct to fusion of the thoracic. lumbar and/or lumbar spine. The Ti-TaMED spinal implant components can be rigidly locked into a variety of configurations, with each case being tailor made for the individual. The Ti-TaMED hooks and cross connectors are intended for posterior only, where as all other components may be used anteriorly or posteriorly.
This document is a 510(k) summary for the Ti-TaMED Spinal System, a spinal fixation device. It describes the device, its components, indications for use, and declares substantial equivalence to predicate devices. It does not contain any information about acceptance criteria or a study that proves the device meets acceptance criteria.
Therefore, I cannot provide the requested information. The document focuses on regulatory approval based on substantial equivalence rather than performance study results against specific acceptance criteria.
§ 888.3070 Thoracolumbosacral pedicle screw system.
(a)
Identification. (1) Rigid pedicle screw systems are comprised of multiple components, made from a variety of materials that allow the surgeon to build an implant system to fit the patient's anatomical and physiological requirements. Such a spinal implant assembly consists of a combination of screws, longitudinal members (e.g., plates, rods including dual diameter rods, plate/rod combinations), transverse or cross connectors, and interconnection mechanisms (e.g., rod-to-rod connectors, offset connectors).(2) Semi-rigid systems are defined as systems that contain one or more of the following features (including but not limited to): Non-uniform longitudinal elements, or features that allow more motion or flexibility compared to rigid systems.
(b)
Classification. (1) Class II (special controls), when intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra; degenerative spondylolisthesis with objective evidence of neurologic impairment; fracture; dislocation; scoliosis; kyphosis; spinal tumor; and failed previous fusion (pseudarthrosis). These pedicle screw spinal systems must comply with the following special controls:(i) Compliance with material standards;
(ii) Compliance with mechanical testing standards;
(iii) Compliance with biocompatibility standards; and
(iv) Labeling that contains these two statements in addition to other appropriate labeling information:
“Warning: The safety and effectiveness of pedicle screw spinal systems have been established only for spinal conditions with significant mechanical instability or deformity requiring fusion with instrumentation. These conditions are significant mechanical instability or deformity of the thoracic, lumbar, and sacral spine secondary to severe spondylolisthesis (grades 3 and 4) of the L5-S1 vertebra, degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion (pseudarthrosis). The safety and effectiveness of these devices for any other conditions are unknown.”
“Precaution: The implantation of pedicle screw spinal systems should be performed only by experienced spinal surgeons with specific training in the use of this pedicle screw spinal system because this is a technically demanding procedure presenting a risk of serious injury to the patient.”
(2) Class II (special controls), when a rigid pedicle screw system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion in the treatment of degenerative disc disease and spondylolisthesis other than either severe spondylolisthesis (grades 3 and 4) at L5-S1 or degenerative spondylolisthesis with objective evidence of neurologic impairment. These pedicle screw systems must comply with the following special controls:
(i) The design characteristics of the device, including engineering schematics, must ensure that the geometry and material composition are consistent with the intended use.
(ii) Non-clinical performance testing must demonstrate the mechanical function and durability of the implant.
(iii) Device components must be demonstrated to be biocompatible.
(iv) Validation testing must demonstrate the cleanliness and sterility of, or the ability to clean and sterilize, the device components and device-specific instruments.
(v) Labeling must include the following:
(A) A clear description of the technological features of the device including identification of device materials and the principles of device operation;
(B) Intended use and indications for use, including levels of fixation;
(C) Identification of magnetic resonance (MR) compatibility status;
(D) Cleaning and sterilization instructions for devices and instruments that are provided non-sterile to the end user; and
(E) Detailed instructions of each surgical step, including device removal.
(3) Class II (special controls), when a semi-rigid system is intended to provide immobilization and stabilization of spinal segments in the thoracic, lumbar, and sacral spine as an adjunct to fusion for any indication. In addition to complying with the special controls in paragraphs (b)(2)(i) through (v) of this section, these pedicle screw systems must comply with the following special controls:
(i) Demonstration that clinical performance characteristics of the device support the intended use of the product, including assessment of fusion compared to a clinically acceptable fusion rate.
(ii) Semi-rigid systems marketed prior to the effective date of this reclassification must submit an amendment to their previously cleared premarket notification (510(k)) demonstrating compliance with the special controls in paragraphs (b)(2)(i) through (v) and paragraph (b)(3)(i) of this section.
