The device description and performance studies focus on the physical and electrical properties of the pacing wires, with no mention of AI or ML capabilities.
Yes.
The device is intended for use in temporary cardiac pacing, which is a therapeutic intervention following cardiac surgery.
No
Explanation: The device is intended for temporary cardiac pacing, which is a therapeutic function, not a diagnostic one. It delivers pacing signals to the heart rather than collecting data for diagnosis.
No
The device description clearly outlines physical components like stainless steel needles, braided wire, and insulation, indicating it is a hardware device, not software-only.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "temporary cardiac pacing following cardiac surgery." This describes a therapeutic intervention performed directly on the patient's heart, not a test performed on a sample taken from the body to diagnose a condition.
- Device Description: The description details a physical wire designed to be implanted into the heart for electrical pacing. This is a medical device used for treatment, not a diagnostic tool.
- No mention of in vitro testing: The text does not mention any analysis of biological samples (blood, tissue, etc.) outside of the body, which is the hallmark of an in vitro diagnostic device.
Therefore, the Weck Cardiac Pacing Wires are a medical device used for temporary cardiac pacing, not an IVD.

Intended Use / Indications for Use
Weck Cardiac Pacing Wires are intended for use in temporary cardiac pacing following cardiac surgery in adult and pediatric patients.

Device Description
Weck cardiac pacing wires consist of a small curved stainless steel needle attached to fluoropolymer coated stainless steel braided wire which is attached on the opposite end to a Keith or Milner breakaway needle (see picture below). The wire is bare at the distal end to allow conduction of pacing signals to the heart. This is a standard temporary epicardial pacing wire design.
There are three design variations included in this submission that are offered as a convenience to the user:
- Color coding White and orange color coding of the insulation allows the user to 1. differentiate between atrial and ventricular wires after chest closure.
-
- Heart needle Three heart needle sizes are intended to allow for variations in physiology between patients. Another variation has no curved heart needle for surgeons who prefer to suture the wire to the epicardium rather than implanting it.
-
- Retention feature A "wing" version wire is formed by peeling back the insulation in three places, 120° apart, for a distance of 1/2" near the curved heart needle. The "wing" is intended as a convenience feature to provide a suture-free method of securing the electrode to the heart.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Weck confirmed biocompatibility of the wires according to FDA G95-1 / ISO 10993-1 requirements.
Weck evaluated each characteristic of the wires important to proper functioning and confirmed that each of the wires is equivalent and performs acceptably with respect to: (1) electrical continuity; (2) strength of the needle swages and ability to withstand tensile forces that may be encountered during use; (3) corrosion resistance; (4) heart needle insertion force: (5) extraction force; (6) fatigue resistance: (7) compatibility with pacemakers; (8) lead pacing impedence; and (9) lead sensing impedence.

§ 870.3680 Cardiovascular permanent or temporary pacemaker electrode.
(a)
Temporary pacemaker electrode —(1)Identification. A temporary pacemaker electrode is a device consisting of flexible insulated electrical conductors with one end connected to anexternal pacemaker pulse generator and the other end applied to the heart. The device is used to transmit a pacing electrical stimulus from the pulse generator to the heart and/or to transmit the electrical signal of the heart to the pulse generator.(2)
Classification. Class II (performance standards).(b)
Permanent pacemaker electrode —(1)Identification. A permanent pacemaker electrode is a device consisting of flexible insulated electrical conductors with one end connected to an implantable pacemaker pulse generator and the other end applied to the heart. The device is used to transmit a pacing electrical stimulus from the pulse generator to the heart and/or to transmit the electrical signal of the heart to the pulse generator.(2)
Classification. Class III (premarket approval).(c)
Date PMA or notice of completion of PDP is required. A PMA or notice of completion of a PDP is required to be filed with the Food and Drug Administration on or before October 4, 2012, for any permanent pacemaker electrode device that was in commercial distribution before May 28, 1976, or that has, on or before October 4, 2012, been found to be substantially equivalent to any permanent pacemaker electrode device that was in commercial distribution before May 28, 1976. Any other pacemaker repair or replacement material device shall have an approved PMA or declared completed PDP in effect before being placed in commercial distribution.

Dear Mr. Young:
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 legally marketed predicate 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 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
