Universal Digital Interface (UDI) 1717

The PTA (Progressive Tibial Alignment) external fixation system is a modular system with the components of: joints, bars, clamps or screws. Such components form a device indicated for reconstruction and corrections of bone segments of the human body. The PTA is for progressive realignment of the knee.

The PTA has multiple components of metallic bone fixation appliances and accessories. It is designed for a progressive correction of the lower limb using tibial osteotomy. This device is composed of a main section of a bar and proximal distraction unit upon which are connected the clamps and grasping components. All components are made of either Aluminum alloy 7012 or Stainless steel, AISI 316 LVM, ISO 5832-1.

The PRIME ECG System is intended for the recording of electrocardiographic signals from the body surface.

The PRIME ECG System uses an 80-lead disposable electrode array referred to as a vest. The electrodes are screen-printed onto a clear plastic substrate. An 80 channel recording device is attached to the vest by means of two spring clips that interface with the printed lead lines. This means that 80 separate electrical signals are collected and stored. The PRIME software also contains a diagnostic algorithm that may be used as an aid in diagnosing AMI. The algorithm provides an explanation of the measurements that were interpreted to reach the suggested diagnosis.

The PRIME ECG is indicated for the recording of electrocardiographic signals on the body surface.

The PRIME ECG System uses an 80-lead disposable electrode array referred to as a vest or harness. The electrodes are screen-printed onto a clear plastic substrate. The section of the vest applied to the anterior side of the patient (anterior harness, applied to chest area) contains channels 1 to 55 and 59 to 64. The section applied to the posterior side of the patient (posterior harness, applied to the patient's back) contains channels 65 to 80. Channels 56, 57 and 58 are applied to the right arm, left arm and left leg, respectively. Signals are conducted along pathways that are also printed, eliminating the need for conventional lead wires. The electrode array or " vest" features pre-applied gel to assure good conductivity and secure attachment. Anatomical markers provide for consistent location on different size patients. The vest can be applied in less than 5 minutes. An 80 channel recording device is attached to the vest by means of two spring clips that interface with the printed lead lines. This means that 80 separate electrical signals are collected and stored. The system measures the ECG recordings simultaneously for all 80 channels. For practical reasons only eight channels are displayed at one time, so the operator may scroll through 10 screens to visualize all active channels. The system contains an algorithm that identifies (with color, words and symbols) any individual electrode that may be suspect, allowing the operator to make adjustments before recording. Once satisfied, the operator activates the recording and the system retains 10.0 seconds of data. If the recording contains any poor signals, the algorithm alerts the operator who must determine whether to accept the recording. The number of poor quality leads may not exceed 6 on the anterior harness. If the signals from any 2 adjacent electrodes, or any posterior electrode, are bad, the maps are not accepted. It is possible for the operator to accept a recording which contains channels that have low quality, but resulting maps contain the legend "Unacceptable Quality" and each poor quality channel is marked in red. Because the electrode vest covers most of the torso, electrode locations include those for a standard 12-lead ECG. This means that among the 80 leads individual locations are consistent with required placement necessary to result in a conventional 12-lead recording and display. There is a user-selected option for displaying these leads, (e.g., the channels are automatically selected and displayed which correspond to a Lead II ECG), although the operator may designate specific electrodes to reflect preferred locations for display. Once the 80-lead recording is accepted, the system creates a series of isopotential and isointegral images (maps) for specific segments of a single beat. Measuring signal strength at a specific time interval of the beat creates Isopotential maps. The resulting strengths and locations of these signals are plotted against an "unwrapped" image of the torso. For example, the unwrapped torso image can be oriented with an x and y axis. At a given point in time, an voltage measurement in millivolts is collected at each location (x,y). This voltage can be plotted along the z axis. If lines are drawn on this plot to connect points with the same voltage z, isopotential contour maps are created. Isopotential maps can be created at any point in time during the cardiac cycle to reflect the cyclic polarization and repolarization of the heart. Isointegral maps are an attempt to provide a look at what is happening over the cycle, as a body surface distribution of the ventricular gradient. At each location (x,y) the potential z changes over the time of the cardiac cycle. Integrating the areas under the QRST of each lead gives the gradient at each point. The gradient at each point is then mapped. Joining points on the plot with the same calculated gradient produces the isointegral contour map. The isointegral map allows evaluation of repolarization properties.
