General Description:

Orthoscan, Inc. TAU Mini C-Arm (K183220) 21CFR 892.1650 Class II Image-intensified fluoroscopic x-ray system, mobile Image-intensified fluoroscopic x-ray system OXO, JAA, MQB

The proposed modifications to Orthoscan, Inc. TAU Mini C-Arm series (which we will refer to internally and in this submittal as Orthoscan TAU 2.0, for distinction from predicate Orthoscan TAU) retain identical function as the predicate TAU Mini C-arm (K183220) as a mobile fluoroscopic mini C-arm system that provides fluoroscopic images of patients of all ages during diagnostic, treatment and surgical procedures involving anatomical regions such as but not limited to that of extremities, limbs, shoulders, knees, and Hips. The system consists of C-arm support attached to the image workstation.

The changes to the Orthoscan TAU series of Mini C-arm X-ray systems represent a modification of our presently legally marketed device Orthoscan TAU mini C-Arm K183220. The proposed modifications to the predicate encompass the implementation of an optional IGZO 15 cm x 15 cm Flat Panel Detector (FPD) in the 15x12cm and 15x15cm device detector sizes, a new LINUX based operating system and related software, image processing board revisions and a revised Power Manager Board for AC to DC conversion that will distribute 24Vdc via a medical grade DC power supply. The proposed device incorporates software architecture and other improvements that

replicate the features and functions of the predicate device and improve image clarity without increasing dose levels.

For both the predicate and proposed device, the following are unchanged; Identical C-arm support and mechanical connections, balancing, locking, rotations, work-station platform, monitor display and main user interface controls, touch screen interface, selectable imaging, X-ray technique control, entry of patient information, wired or wireless footswitch operation, interface connection panel and DICOM fixed wire and wireless network interfaces.

The proposed modifications to Orthoscan, Inc. TAU Mini C-Arm series do not change the identical intended use. Intended use is the same as the predicate device TAU (K183220) Mini C-Arm.

Indications for Use: The Orthoscan TAU Mini C-arm is designed to provide physicians with general fluoroscopic visualization, usinq pulsed or continuous fluoroscopy, of a patient including but not limited to, diagnostic, surgical, and critical emergency care procedures for patients of all ages including pediatric populations when imaging limbs/extremities, shoulders; at locations including but not limited to, hospitals, ambulatory surgery, emergency, traumatology, orthopedic, critical care, or physician office environments.

> The proposed modifications to Orthoscan, Inc. TAU Mini C-Arm series do not change the indications for use. The indications for use are the same as the predicate device TAU (K183220) Mini C-Arm.

Technology: The changes to proposed device Orthoscan TAU 2.0 series of Mini C-arm X-ray systems represent a modification of our presently legally marketed device Orthoscan TAU Mini C-Arm K183220. The proposed device will provide an option in supplier of detectors. The optional IGZO Solid-State X-ray Imagers (SSXI) provide newer technology in the Flat Panel Detectors (FPD). The inclusion of IGZO detector size 15cmx15cm in the 15cmx15cm sized Orthoscan device will also be fitted into the smaller active field

{6}------------------------------------------------

model 15cmx12cm sized device with minor mechanical modifications.

The proposed modified TAU 2.0 will be equipped with a revised Power Manager Board for AC to DC conversion that will distribute 24vdc via a new medical grade DC power supply. This supply will power all electronic sub-assemblies. The AC to DC conversion will provide intrinsic value through risk reduction such as leakage, while standardizing distribution of 24Vdc.

With the introduction of a Linux based operating system (OS) an open source highly secure OS, and revisions to the image processing board, software architecture design has been improved and functions are identical to that of the predicate device Orthoscan, Inc. TAU Mini C-arm (K183220).

Summary of Technological Characteristics: The comparisons of the proposed modifications to Orthoscan, Inc. TAU Mini C-Arm demonstrate that the scientific and technology characteristics indicate substantial equivalence to the predicate device Orthoscan, Inc. TAU Mini C-Arm (K183220).
