K/DEN Number and list them here in a comma separated list exactly as they appear in the text:

Not Found

No
The summary describes a standard cardiac pacing lead with no mention of AI or ML capabilities. The performance studies focus on electrical and mechanical properties, not algorithmic performance.

Yes

This device is a cardiac lead designed to provide a permanent electrical pathway between a pacemaker and the atrium, thus delivering therapeutic electrical impulses for pacing and sensing.

No

Explanation: The device, an endocardial lead, is designed for permanent pacing and sensing, creating an electrical pathway between a pacemaker and the atrium. Its purpose is therapeutic (pacing) and monitoring (sensing), not to diagnose a condition.

No

The device description clearly states it is a physical lead made of silicone rubber and other materials, designed to be implanted. It also describes physical testing performed on the lead.

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

Here's why:

  • Intended Use: The intended use is for "permanent pacing and sensing of the atrium" in conjunction with implantable cardiac pacemakers. This describes a device that is implanted within the body to interact directly with the heart's electrical activity.
  • Device Description: The description details a "transvenous lead" that provides an "electrical pathway between a pacemaker and the atrium." This is a physical component of an implanted medical device system.
  • Lack of IVD Characteristics: IVD devices are designed to examine specimens (like blood, urine, or tissue) in vitro (outside the body) to provide information about a person's health. The provided information does not mention any interaction with biological specimens or analysis performed outside the body.

Therefore, the Stela™ Model UJ45 lead is an implantable medical device, not an in vitro diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The following in-vitro functional testing was performed on the Stela™ Model UJ45 leads:

  • · stylet insertion/removal
  • · stylet bottoming
  • · electrical resistance
  • · IS-1 connector conformity
  • · leak resistance
  • · insulation integrity
  • · tensile strength test.
    Biocompatiblity testing was not performed, due to the successful history with the same materials in other lead products. No new sterilization testing or mechanical / environmental packaging validation were performed, because the lead package design and sterilization method did not change from the Stela™ Model BJ45.
    No clinical study was required to demonstrate safety and effectiveness since the Stela™ Model UJ45 presents no new feature.
