The C3 Wave System is indicated for use in the positioning of Peripherally Inserted Central Catheters (PICC). The C3 Wave provides real-time catheter tip location information by displaying changes in the patient's cardiac electrical activity. The C3 Wave is indicated for use as an alternative method to chest X-ray or fluoroscopy confirmation of PICC tip placement in adult patients. Note: Limiting, but not contraindicated, situations for this technique are patients where cardiac rhythms may change presentation of the P-Wave: -Atrial fibrillation -Atrial flutter - Severe tachycardia -Pacemaker-Driven Rhythm -Chronic obstructive pulmonary disease (COPD) Such patients are easily identified prior to PICC insertion. Use of additional method is necessary to confirm catheter tip location.

C3 Wave is designed to provide a continuous display of electrocardiograph [ECG] waveform to be used as a quide in placement of peripherally-inserted central catheters [PICC] in the lower third of the Superior Vena Cava [SVC] of a patient. The principle for operation of this system uses three ECG leads placed on the patient's chest and generates a third ECG lead by switching from RA to PICC stylet. The ECG waveform is wirelessly transmitted to a tablet which allows the operator to view and record changes to the ECG waveform as the tip of the catheter approaches the heart. As the PICC catheter approaches the atrium of the heart, the P wave in the ECG waveform shows substantial changes. This system is designed to aid the visualization of changes in P wave amplitude.
