This device generates ultrasonic vibrations intended for ultrasonic procedures: 1.) General Supra and Subgingival scaling applications; 2.) Periodontal debridement for non-surgical treatment of Periodontal diseases.

The Swerv Magnetostrictive Ultrasonic Scaler is a portable stand alone scaler, handpiece and foot control. The Swerv Magnetostrictive Ultrasonic Scaler operates at 25 kHz and accepts voltage inputs between 100-240V. The available power output is segmented into two over zones to assist the user in selecting the recommended power setting for a selected ultrasonic insert. The power and water controls of the Swerv' Scaler are located in the control unit. The Swerv2 Magnetostrictive Ultrasonic Scaler plugs into an ordinary electrical outlet and converts the AC current into high frequency electro-mechanical vibrations. The Swerv3 Scaler features a patented switching mechanism to support the use of either 25 kHz or 30 kHz inserts. Therefore, the scaling system accepts both Hu-Friedy 25 kHz and 30 kHz Ultrasonic Inserts.

This product is intended for use by dental professionals only. This device is an accessory to the EI DownPak Endodontic Obturator Handpiece which is used in the oral cavity for root canal therapy. The barrier sleeve will be used to cover the hand piece thereby reducing the risk of cross infection while in use.

The EI® brand DownPak Barrier Sleeves are similar to the TIDI Product (SaniTherm) Disposable Thermometer Sheaths listed above. The El DownPak Barrier sleeve and the predicate TIDI Products Disposable Thermometer Sheaths are intended for use by medical professionals in the oral cavity as infection control devices. The EI DownPak Barrier Sleeve will be use to cover the El DownPak Endodontive Obturator Handpiece which is used for root canal therapy. The CDC Guidelines for Infection Control in Dental Healt Care Settings (Vol. 52, No. RR-17, ng 20, December 19, 2003) references the use of disposable barrier protection. The El DownPak Barrier sleeves will be used in combination with the cleaning instructions for the EI DownPak Obturator handpiece which recommends wiping the surface of the handpiece with a soft cloth dampened with pH neutral surface disinfection solution or mild detergent (not containing phenols). Hu-Friedy will purchase the barrier sleeves from TIDI Products, formerly Banta Healthcare Products, as an own brand private label device. The EI DownPak Barrier Sleeves are identical to the TIDI Products Disposable Sheaths in shape, material, and design. All of the technical specifications are identical to the marketed TIDI Products device. EI has 510k (K070246) approval to market the marketed device in the US. The EI DownPak barrier sleeves are compatible with the EI DownPak handpiece. The El DownPak barrier sleeves are identical to the TIDI Products Disposable Thermometer Sheaths. All of TIDI Products probe cover products (i.e. thermometer sheath, instrument sheaths, and dental camera covers) arc manufactured to ASTM E1104-98. The material construction meets the requirements for poly products, referenced in Part 177 21 CFR (specifically 177.1340 and 177.1520). These sheaths have been tested and certified to be in compliance for sensitization, cytoxicity, and irritation as specified in ISO 10993 eomphally, these sheaths have been tested and certified to be in compliance for viral penetration in accordance with ASTM F1671.

This product is intended for use by dental professionals only. This device generates ultrasonic vibrations intended for use in dental applications such as scaling, periodontal therapy, root canal treatment and cavity preparation.

The Hu-Friedy® brand Symmetry IQ Ultrasonic Scalers are similar to the Ultrasonic Scalers of the predicate device listed above. These devices are intended for use by dental professionals only. These devices generate ultrasonic vibrations intended for use in dental applications such as scaling, periodontal therapy, root canal treatment and cavity preparation. Hu-Friedy will purchase the generators from NSK, Inc. (Nakanishi) and own brand private label the device. The modifications to the Hu-Friedy product are cosmetic in nature and consist mainly of new shape and design to the housing of the control unit. All of the internal electrical and technical specifications are identical to the marketed NSK units. Hu-Friedy currently has a 510k (K053178) approval for the Symmetry line of piezoelectric tips that are compatible with Satelec and NSK piezoelectric ultrasonic scalers. The addition of the Symmetry IQ generators and handpiece will complete our ultrasonic piezo scaling product line. The Symmetry IQ Ultrasonic Scalers have essentially the same design as the predicate device's ultrasonic generators. The Symmetry IQ 2000 series is equivalent to the Varios 150 Lux (Optic), which is an integrated version of the Varios 350 Lux (Optic) to be used in the delivery tray table as a built in system. The Symmetry IO 3000 series is equivalent to the combination of the Varios 550 control unit with the handpiece used in the Varios 350 Lux (Optic). The Symmetry IQ 3000 unit is based on the NSK Varios 560 which is currently pending FDA 510k approval. The addition of a silicone grip to the ultrasonic generator handpiece used in both models is the only significant change and the reason for the new 510k application.
