INTENDED USE The TT1 General Purpose Coil is a receive-only diagnostic MR imaging coil designed for use at a static magnetic field strength of 1.5T with the GE Signa® 1.5T system. It is used for obtaining diagnostic images of a variety of small-to-medium sized anatomical regions, such as jaw, spine, neck, shoulder, thigh, foot, ankle and joints. #### C. DEVICE DESCRIPTION The TT1 General Purpose Coil is a linear receive-only coil for operation at a magnetic field strength of 1.5T with the GE Signa® 1.5T system. The coil is a single element coil consisting of a 3-inch diameter loop. Coupling of the coil to the transmitted field is prevented through an active blocking circuit. The TT1 General Purpose Coil is specially designed for MR imaging of small-to-medium sized anatomical regions, such as jaw, spine, neck, shoulder, thigh, foot, ankle and joints. The coil provides optimum signal to noise ratio and coverage, allowing high-resolution imaging, while the sensitive region of the coil covers an approximately a 10 cm Field of View. #### D.

PREDICATE DEVICES The TT1 General Purpose Coil is substantially equivalent to the predicate devices. The table below identifies similarities between the devices. Although the GE 3-inch General Purpose Coil is in commercial distribution it is not included in the FDA 510(k) database and/or has been purged from the FDA PMA database. Tursiop Technologies LLC has conducted side by side testing between the TT1 General Purpose Coil and the GE 3-inch General Purpose Coil to verify substantial equivalence. | Para<br>mete<br>r | TT1 General Purpose Coil | Predicate Coil: GE 3-inch General<br>Purpose Coil | Predicate Coil: MRgFUS General<br>Purpose and Breast Coil (K061715) | |---------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Intended/Indications for<br>Use | The TT1 General Purpose Coil is<br>a receive-only diagnostic MR<br>imaging coil designed for use at a<br>static magnetic field strength of<br>1.5T with the GE Signa® 1.5T<br>system.

SAFETY AND EFFECTIVENESS Tursiop Technologies, L.L.C will comply with FDA's GMPs and the TT1 General Purpose Coil does comply with voluntary standards for safety/effectiveness (IEC 60601, UL 94) all of which mandate that components are tested to minimize hazards (electrical, mechanical, and flammability). A risk assessment (FMEA) has been conducted. Risk management practices will be utilized to assess potential risks throughout the device life cycle and mitigate unacceptable levels of risk. Tursiop Technologies, L.L.C. has conducted testing to establish the safety and effectiveness concerning the TT1 General Purpose Coil. Side by side comparison testing was conducted with the predicate device, GE 3-inch General Purpose Coil which demonstrated substantially equivalent performance. The TT1 General Purpose Coil does not introduce any new potential safety risks and operates in a manner similar to the predicate devices. #### G. SUBSTANTIAL EQUIVALENCE STATEMENT The TT1 General Purpose Coil is substantially equivalent to the GE 3-inch General Purpose Coil and the MRgFUS General Purpose and Breast Coil (K061715). This opinion is based on the fact that comparing the TT1 General Purpose Coil technological characteristics, coil architecture and operating principles with that of the predicate devices reveals that the devices comply with the same or equivalent standards and have the same or equivalent intended uses. {3}------------------------------------------------ # DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/3/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
