Intended Use

The Cynch System is indicated intervertebral body fusion of the fumbar spine, from L2 to S1, in skeletally mature patients who have had six months of non-operative treatment. The device is intended for use at either one level or two contiguous levels for the treatment of degenerative disc disease (DDD) with up to Grade I spondylolisthesis. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The device system is designed for use with supplemental fixation and with autograft to facilitate fusion.

Device Story

SpineSmith Cynch Spinal System is an intervertebral body fusion device; used for lumbar spine fusion (L2-S1). Configurations include TLIF, PLIF, and T-PLIF approaches. Implants are hollow PEEK Optima LT1 cages with large anterior windows for autograft bone placement; feature superior/inferior teeth for stability and horizontal grooves for instrument positioning. Three radiopaque tantalum markers assist surgeon with placement. Used in surgical setting by physicians; requires supplemental fixation. Benefits include stabilization of spinal segments and facilitation of fusion in patients with degenerative disc disease.

Clinical Evidence

Bench testing only. Mechanical testing performed per ASTM F2077-03 (static/dynamic compression), ASTM F2267-04 (subsidence), and ASTM Draft Standard F-04.25.02.02 (expulsion). No clinical data provided.

Technological Characteristics

Material: PEEK Optima LT1 (ASTM F2026) with tantalum markers (ASTM F-560-05). Design: Hollow-body cage with teeth and grooves. Energy source: None (mechanical). Connectivity: None. Sterilization: Not specified.

Indications for Use

Indicated for skeletally mature patients with degenerative disc disease (DDD) and up to Grade I spondylolisthesis requiring intervertebral body fusion of the lumbar spine (L2-S1) after 6 months of failed non-operative treatment.

Regulatory Classification

Identification

An intervertebral body fusion device is an implanted single or multiple component spinal device made from a variety of materials, including titanium and polymers. The device is inserted into the intervertebral body space of the cervical or lumbosacral spine, and is intended for intervertebral body fusion.

Special Controls

*Classification.* (1) Class II (special controls) for intervertebral body fusion devices that contain bone grafting material. The special control is the FDA guidance document entitled “Class II Special Controls Guidance Document: Intervertebral Body Fusion Device.” See § 888.1(e) for the availability of this guidance document.(2) Class III (premarket approval) for intervertebral body fusion devices that include any therapeutic biologic (e.g., bone morphogenic protein). Intervertebral body fusion devices that contain any therapeutic biologic require premarket approval. (c) *Date premarket approval application (PMA) or notice of product development protocol (PDP) is required.* Devices described in paragraph (b)(2) of this section shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.

Predicate Devices

#### IDENTIFICATION OF PREDICATE DEVICES:

The SpineSmith Cynch System was determined to be substantially equivalent to the previously cleared Cynch System (K090376, SpineSmith; Cleared 2/16/2009) and the down classified Lumbar I/F cage (P960025, Depuy; Approved 3/4/2005).

### DEVICE DESCRIPTION:

The SpineSmith Cynch System is offered in two (2) configurations of various sizes. The configurations are designed based on indicated spinal implant level and surgical approach. The system consists of the Cynch TLIF device for transforaminal lumbar approach and the Cynch PLIF/T-PLIF device, which may be implanted via a posterior lumbar bi-lateral approach or transverse lumbar approach. The Cynch System implants are manufactured from PEEK Optima LT1 and contain three (3) radiopaque tantalum markers to assist the surgeon with proper placement of the device.

The Cynch System implants are hollow to allow for the placement of autograft bone, and have large anterior graft windows to facilitate fusion. There are teeth on the superior and inferior surface of the implants to provide increased stability and inhibit movement of the implant. The implants have horizontal grooves to locate the implant holder superior/inferior and rotationally. Additionally, a cross-bar is provided to minimize buckling during insertion.

## INDICATIONS:

The Cynch System is indicated for intervertebral body fusion of the lumbar spine, from L2 to SI, in skeletally mature patients who have had six months of non-operative treatment. The device is intended for use at either one level or two contiguous levels for the treatment of degenerative disc disease (DDD) with up to Grade I spondylolisthesis. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The device system is designed for use with supplemental fixation and with autograft to facilitate fusion.

# SUMMARY OF TECHNOLOGICAL CHARACTERISTICS:

The purpose of this submission is to add the Cynch PLIF/T-PLIF device, which may be implanted yia a posterior lumbar bi-lateral approach or transverse lumbar approach. The Cynch System implants are manufactured from PEEK Optima LT1 and contain three (3) radiopaque tantalum markers to assist the surgeon with proper placement of the subject device (Cynch PLIF / T-PLIF) has similar technological characteristics as the predicate devices identified above (SpineSmith's Cynch System per K090376, and Depuy's Lumbar I/F cage per P960025). Specifically, the following characteristics support this conclusion:

- Intended for use at either one level or two contiguous levels for the treatment of degenerative disc disease (DDD) with up to Grade I spondylolisthesis.
- Hollow-body implant design to allow for placement of autograft bone -
- -Implant material: PEEK Optima LT1 per ASTM F2026 with radiopaque tantalum markers per ASTM F-560-05
- Substantially equivalent results of non-clinical testing relative to static and dynamic compression (per ASTM F2077-03), subsidence (per ASTM F2267-04), and expulsion (per ASTM Draft Standard F-04.25.02.02)

# DISCUSSION OF NON-CLINICAL TESTING:

The following non-clinical tests were conducted:

- Static and dynamic compression testing, conducted in accordance with ASTM F2077-03 -
- Subsidence testing, conducted in accordance with ASTM F2267-04 .
- . Expulsion testing, conducted in accordance with ASTM Draft Standard F-04.25.02.02

# CONCLUSIONS:

The subject and predicate devices share the same intended use, primary implant design and material of manufacture. The non-clinical mechanical test results demonstrate that any minor differences do not impact device performance as compared to the predicates and demonstrate that the Cynch System is substantially equivalent to the predicate devices.
