Device inserted into heart chambers; allows physician to record intracardiac electrical activity and deliver electrical stimuli to myocardium to increase heart rate or maintain cardiac output. Used in clinical settings by trained medical professionals. Provides diagnostic mapping data and therapeutic pacing capability; assists in managing cardiac arrhythmias or hemodynamic instability until definitive treatment. Benefits patient by providing temporary rhythm support and diagnostic information. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Quadpolar electrode configuration; includes stylet for structural support/placement; designed for intracardiac mapping and pacing. Materials and sterilization methods consistent with standard cardiovascular catheter requirements. ## 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).

Konieczny Regulatory Affairs Engineer Harmac Medical Products, Inc. 2201 Bailey Avenue Buffalo, New York 14211-1797 Re: K963074 Trade Name: Harmac Quadpolar Mapping Pacing Catheter Regulatory Class: II Product Code: 74DRF Dated: March 25, 1997 Received: March 28, 1997 Dear Mr. Konieczny: We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. 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 requirement, 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. {1} Page 2 - Mr. Joseph M. Konieczny This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4648. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
