The PiGalileo™ Total Hip Replacement (THR) software application when provided with the PiGalileo™ system cart results in the PiGalileo™ THR System, a softwarecontrolled electromechanical stereotaxic device for computer-aided navigation of PiGalileo™ surgical instruments with the purpose of assisting the surgeon in optimally positioning hip prostheses. Refer to Section 11.0 for an in depth description of the PiGalileo™ THR System. The PiGalileo™ THR System is intended to be used in computer-assisted orthopedic surgery to aid the surgeon with bone cuts and implant positioning during joint replacement. It provides information to the surgeon that is utilized to place surgical instruments during surgery utilizing anatomical landmarks and other data specifically obtained intra-operatively. The PiGalileo™ THR System is based on common stereotaxic technology in which Infrared (IF) LED (light emitting diodes) or passive markers on the surgical instruments allow the instruments to be tracked in real time in the surgical field. In the case of PiGalileo™ THR System, patient data that is required to navigate the surgical instruments is collected during the procedure. The system utilizes this data to establish a connection between passive locaters, i.e., Infrared (IF) light, and the system's IF camera as previously described tracks the surgical instruments in real time in the surgical field. The precision of navigation-assisted surgery depends on accurate scanning of skeletal landmarks. Scanned morphological data represents the basis for calculating the position of the hip cup and hip stem. Scanned points must represent unique anatomic landmarks so that they can be located in a safe and reproducible manner throughout surgery. For cup navigation, the spinae, left/ right are scanned as well as the symphysis. Each point is scanned three times to enhance precision and used for inclination and anteversion alignment. For stem navigation, the sagital plane is determined from the tibialis anterior and the intersection point on the femur. The position and alignment of the proximal stem axis are determined with a probe which provides the basis of the varus/valgus alignment. The surgeon maintains control of the operation and any decisions required with regard to the surgery at all times. Risk mitigations implemented under Design Controls ensure that sufficient fail safe mechanisms allow the surgeon to convert to non-navigated conventional surgical techniques at any time. The navigation platform for the PiGalileo™ THR System is the same as the navigation platform cleared under PiGalileo™ TKR System, K061362, and includes the following elements: (a) System Cart housing the following items; there are no changes to the system cart as compared to K061362. 1 System electronics such as CPU and connection box Monitor User Interface consisting of keyboard, touch pad and hard controls, e.g., "ON / OFF", footswitch Infrared (IF) Camera and Camera Stand/Tripod Optional printer System cabling (b) PiGalileo™ THR Software refers to the PiGalileo™ System Software and the THR software application: PiGalileo™ System Software: this software is the same as that of the PiGalileo™ TKR System; there are no changes to either the system software or the calculations or the landmark technique as compared to K061362. PiGalileo™ THR software application consists of two applets, PiGalileo™ Hip Cup and PiGalileo™ Hip Stem. Each applet consists of a collection of software modules that support the surgeon in hip cup and hip stem replacement.

The modified PROMOS® Modular Shoulder System is intended to aid in the restoration of shoulder motion and elimination of pain. This device consists of two primary components, the glenoid component and the modular humeral component. The changes to the PROMOS® Shoulder that resulted in the modified PROMOS® Shoulder and are subject of this 510(k) include: - Addition of size 3.5 humeral stem, cementless . - Addition of six humeral ball heads R21 R26, with 4 mm eccentricity . - Redesign of body and inclination set to add face gear to area between . inclination set and body - Addition of three Monoblock stems, cementless, size 02/30, 35 and 40 mm . - Various labeling changes . The glenoid component has a spherical articulating surface with four pegs on the inferior surface for attachment to the bone. It is manufactured from ultra high molecular weight polyethylene (UHMWPe) according to ISO 5834-2:1998, Implants for Surgery - Ultra-High-Molecular-Weight Polyethylene - Part 2: Moulded Forms. The glenoid is available in four sizes with each size having three different spherical radii of curvature for a total of twelve glenoid components. The modular humeral component consists of a distal stem, body, inclination set and humeral head. The distal stem is rectangular in cross-sectional shape, previously available in seven cemented and seven cementless sizes, and now available in seven cemented and eight cementless sizes. It is attached to the body via a Morse type taper. The cementless and cemented stems are fabricated from titanium alloy (Ti6Al4V) according to ISO 5832-3:1996, Implants for surgery -- Metallic materials -- Part 3: Wrought titanium 6-aluminium 4-vanadium alloy. The body is made of same titanium alloy as the distal stems and is available in three sizes. The body and inclination set have been redesigned to add a face gear to the area between the inclination set and body. As before the modified inclination set consists of three components: an inclination insert, an offset module, and a ball head screw. The modular humeral heads are manufactured from wrought cobalt-chromiummolybdenum (CoCrMo) alloy according to ISO 5832-12:1996, Implants for surgery -- Metallic materials -- Part 12: Wrought cobalt-chromium-molybdenum alloy, previously available in eight different sizes/eccentricities, and now available in 14 different sizes/eccentricities. Since cementless or cemented stems in size 01 may be too large for some patients, the company has developed a humeral stem, size 02. The narrow crosssection of a size 02 stem precluded a modular design, i.e., 02 size stem and a selection of bodies. As a result, the company implemented the size 02 as a Monoblock system with three different heights for body sizes 30mm, 35mm, and 40mm. The design of the cross-section is the same as mentioned above in the description of the distal stem and the stem is made of the same titanium allov. The proximal portion has also been redesigned to add face gear to the area between inclination set and body.

The PiGalileo™ Navigation (NAV) Total Knee Replacement (TKR) Computer Assisted Surgical (CAS) System (PiGalileo™ TKR System) is a softwarecontrolled electromechanical sterotaxic device for computer-aided navigation of PI Galileo surgical instruments with the purpose of assisting the surgeon in optimally positioning prostheses of the TC-PLUS and VKS knee systems. The PiGalileo™ TKR System is based on common stereotaxic technology in which Infrared (IF) LED (light emitting diodes) or passive markers on the surgical instruments allow the instruments to be tracked in real time in the surgical field. In the case of PiGalileo™ TKR System, patient data that is required to navigate the surgical instruments is collected during the procedure. The system utilizes this data to establish a connection between passive locaters, i.e., Infrared (IF) light, and the system's IF camera as previously described tracks the surgical instruments in real time in the surgical field. Two passive locators are attached to the tibia and distal femur during surgery, where one locater is mobile to determine specific landmarks, known as Bone Referencing (BR) on the tibia and femur. Once the system has collected the information, the system positions a motorized cutting guide on the femur to support the surgeon during surgery and provides information to position or "navigate" additional instruments. The surgeon maintains control of the operation and any decisions required with regard to the surgery at all times. Positions of the motorized cutting guide may also be adjusted manually. Risk mitigations were implemented under Design Controls to ensure that sufficient fail safe mechanisms allow the surgeon to convert to non-navigated conventional surgical techniques at any time. The PiGalileo™ TKR System consists of three main elements: - System Cart which houses: - System electronics and cabling - Monitor - User Interface - IF Camera and Camera Stand - Optional printer - Software: - PiGalileo System Software - Application Software - a) PiGalileo TKR BR - b) PiGalileo TKR Ligament Balancing (LB) - c) PiGalileo TKR Light - d) PiGalileo TKR Minimally Invasive Surgery (MIS) - Standard Surgical Instruments and application-specific surgical instruments
