The Constellation Multiple Electrode systems alone (i.e., linear mapping catheters), and manually generated pacing stimuli. ## Device Story Constellation Multiple Electrode Recording and Pacing Catheter System is a high-density array intracardiac mapping catheter. It is used in right atrial electrophysiology procedures to assist in diagnosing complex arrhythmias. The device functions by providing high-density mapping and manually generated pacing stimuli, which allows for better identification of arrhythmias compared to conventional linear mapping catheters. It is operated by physicians in a clinical setting. The system includes various catheter models (unipolar/bipolar, coated/uncoated), sheaths, a pacing switchbox, and cables. The output is used by the physician to interpret cardiac electrical activity and guide clinical decision-making regarding arrhythmia treatment. The device is intended to benefit patients by improving the diagnostic accuracy of complex cardiac rhythm disorders. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics High-density array intracardiac mapping catheter system. Components include unipolar and bipolar electrodes, coated and uncoated catheter options, sheaths, pacing switchbox, and cables. Operates as an electrophysiology mapping and pacing tool. No software or electronic processing described. ## Regulatory Identification An electrode recording catheter or an electrode recording probe is a device used to detect an intracardiac electrocardiogram, or to detect cardiac output or left-to-right heart shunts. The device may be unipolar or multipolar for electrocardiogram detection, or may be a platinum-tipped catheter which senses the presence of a special indicator for cardiac output or left-to-right heart shunt determinations. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

You may, the reachar rood, bray, subject to the general controls chercrore, marked and the limitations described below. The provisions of the rovisions of the Act include requirements for general concrolo provision of devices, good manufacturing annual regiberaing, and prohibitions against misbranding and adulteration. The Office of Device Evaluation has determined that there is a reasonable likelihood that this device will be used for an intended use not identified in the proposed labeling and that incended abound rate form. Therefore, in accordance with Section {1}------------------------------------------------ Page 2 - Mr. Steve Jwanouskos 513(i)(1)(E) of the Act, the following limitation must appear in the Warnings section of the device's labeling: The use of this device in conjunction with WARNING: radiofrequency ablation, as part of the diagnosis and treatment of cardiac arrhythmias, may pose an increased risk of adverse events, such as cardiac perforation, myocardial infarction, air embolism, and hematoma requiring surgical repair and/or blood transfusion. The Warning must be presented within a black box, and the font size of the text should be at least 2 points larger than any surrounding text. The Warning must be present on the first page of your Operator's Manual, and on the packaging for each individual device. If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and permits your device to proceed to the market. This letter will allow you to begin marketing your device as described in your 510(k) premarket notification if the limitation statement above is added to your labeling, as described. Please note that the above labeling limitations are required by Section 513(i)(1)(E) of the Act. Therefore, a new 510(k) is required before these limitations are modified in any way or removed from the device's labeling. {2}------------------------------------------------ #### Page 3 - Mr. Steve Jwanouskos If you desire specific information about the application of other labeling requirements to your device (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4646. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639.
