The safety and efficacy of this device has not been established in the thoraci and cervical intervertebral regions of the spine and should not be used in those negions. The Ultrazonix Spine Minimal-Invasive Disc System is comprised of a non-disposable Control Unit, and a sterile, single-use Probe Kit. These two major component parts are described as follows: #### a) Non disposable Control Unit This contains a power supply, a high frequency-generator, an amplifier, an independent safety system and a user interface with an alphanumerical display and a key pad and a foot-operated switch. The probe and a foot-operated switch are connected to the Control Unit. High frequency induced ultrasound is emitted from the probe and controlled by means of the foot-operated switch. ## b) Sterile, single-use Probe Kit, consisting of A blunt 500 mm long stainless steel Guide Pin with a diameter of 2 mm. The Guide Pin is used as a pathfinder to navigate towards the spinal disk under fluoroscopic guidance. {1}------------------------------------------------ A 5.3 mm Dilator which is used to prepare a canal for the Introducer. It has a conical front which ensures as little harm as possible is done to adjacent tissue and blood vessels A 6 mm Introducer which is a thin walled, approximately 180 mm long tube with a handle to be used as a guide for the Probe. It is placed over the Dilator and when the desired position against the disk is reached the Guide Pin and the Dilator are removed and The ultrasonic Probe is inserted into the Introducer. It consists of a thin shaft with a piezo ceramic transducer placed at the front /tip. ## Predicate Devices: There has been a device previously cleared by the FDA in the following 510(K) Notification indicated for use for the coagulation and decompression of disc material to treat symptomatic patients with annular disruption of contained herniated discs. | Device | 510(k) Document Number | Date Cleared | Indications | |-----------------------------------------------------------------------------------------------------------------------------------|------------------------|------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------| | Oratec SpineCATH<br>Intradiscal Catheter<br>&<br>Oratec ORA-50 S<br>Auto Temp Electro<br>Thermal Spine<br>System &<br>Accessories | K974464<br>K993854 | 3/19/1998<br>12/6/1999 | coagulation and<br>decompression of disc<br>material to treat<br>symptomatic patients<br>with annular<br>disruption of<br>contained herniated<br>discs | | Epicor Medical<br>UltraCinch Tissue<br>Ablation Device and<br>Accessories | K040641 | 5/5/2004 | For the ablation of<br>cardiac tissue during<br>cardiac Surgery | #### Table 6. Predicate Device(s) Technologically, both the proposed and predicate devices are substantially equivalent. Both proposed and predicate devices are electrosurgical devices which are indicated for use for the coagulation and decompression of disc material to treat symptomatic patients with annular disruption of contained lumbar herniated discs. Both the proposed and predicate devices utilize heat generated at the tip of the catheter / probe to deliver thermal {2}------------------------------------------------ ## 510(k) Notification Supplement K060346-Ultrazonix Spine Minimal-Invasive Disc System December 19, 2006 energy to the tissue. Both also utilize a radiopaque marking at the proximal end of the catheter/probe to position the catheter/probe under fluoroscopy. Any differences between the two devices do not raise new questions of safety and effectiveness. ## Intended Use: ## Ultrazonix Spine Minimal-Invasive Disc System Indications: The Ultrazonix Spine Minimal-Invasive Disc System is intended for use by professional medical personnel for coagulation and decompression of intervertebral disc material to treat symptomatic patients with annular disruption of contained herniated lumbar discs. The safety and efficacy of this device has not been established in the thoracic and cervical intervertebral regions of the spine and should not be used in those regions. ## Technological Characteristics: Technologically, both the new device and the predicate device are the same (i.e. both are intended for use for the coagulation and decompression of lumbar disc material to treat symptomatic patients with annular disruption of contained lumbar herniated discs). Any differences between the two devices do not raise new questions of safety and effectiveness ## Performance Data: Results of in vitro and animal study evaluations show that the Ultrazonix Spine Minimal-Invasive Disc System functions as intended. Sufficient pre-clinical data has been gathered to qualify that the system is safe and efficient in coagulation and decompression of disc tissue. Current clinical experiences also show that the product is safe in coagulation and decompression of lumbar discs. ## Conclusions: Based on the 510(k) summaries and 510(k) statements (21 CFR 807) and the information provided herein, we conclude that the modified device is substantially equivalent to the existing legally marketed device under the Federal Food, Drug and Cosmetic Act. {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the seal of the Department of Health and Human Services (HHS) of the United States.
