More Information

Not Found

No
The summary describes a material change in existing pacing leads and focuses on mechanical and electrical performance testing, with no mention of AI or ML.

Yes
The device, an endocardial lead, is designed to be used with implantable cardiac pacemakers. Pacemakers are therapeutic devices that regulate heart rhythm, and the lead is an essential component for delivering this therapy to the heart.

No

Explanation: The device is described as a "pacing lead" designed to provide a "permanent electrical pathway between a pacemaker and the ventricle/atrium." Its function is to facilitate pacing, not to diagnose a condition.

No

The device description explicitly states that the device is a silicone rubber, transvenous lead, which is a physical hardware component. The summary also details material changes and physical testing performed on the leads.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for "implantation in the ventricle" and "implantation in the atrium" to provide an electrical pathway between a pacemaker and the heart. This is a therapeutic and diagnostic device used in vivo (within the body), not in vitro (outside the body).
  • Device Description: The description details a physical implantable device (leads) made of silicone rubber, designed to be placed inside the body.
  • Performance Studies: The performance studies described are related to the physical and electrical properties of the leads and their biocompatibility when implanted in animals. These are not typical studies for an IVD, which would focus on analyzing samples like blood, urine, or tissue in vitro.

IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device is a medical implant used to treat or manage a cardiac condition by interacting directly with the heart.

§ 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.
