Yes
The device is used for defibrillation, which is a therapeutic intervention to treat cardiac arrhythmias by delivering an electrical shock to the heart.

No

Explanation: The device is a set of paddles used with defibrillators to deliver electrical shocks for defibrillation, which is a therapeutic treatment. It is not described as performing any diagnostic function.

No

The device is described as physical paddles with a shock button and undergoes hardware testing, biocompatibility testing, and sterilization validation, indicating it is a hardware device, not software-only.

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

Here's why:

  • Intended Use: The intended use is to "defibrillate the heart during open-chest surgical procedures." This is a direct therapeutic intervention on a living patient, not a test performed on a sample taken from the body to diagnose a condition.
  • Device Description: The description details a device used to deliver an electrical shock to the heart, which is a treatment, not a diagnostic test.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific markers, or providing diagnostic information based on laboratory analysis.

IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This device does not fit that description.

reprocessing cycles.
Biocompatibility
TestingBiocompatibility testing was repeated for confirmatory
purposes to ensure any unanticipated material drift since
the last product iteration, as described in Table 10-4 and
Table 13-2 , to ensure that the switched internal paddles
remain in compliance with the requirements of ISO
10993-1:2009, Biological evaluation of medical devices
– Part 1: Evaluation and testing within a risk
management process.

While previous premarket submissions included Switched Internal Paddles, Switchless Internal Paddles, and External Paddles, this Special 510(k) submission only includes Switched Internal Paddles and therefore, the updated IFU only includes instructions for using and reprocessing Switched Internal Paddles.

V. Intended Use

Note that the intended use statement has been narrowed to include the specific compatible HeartStart Defibrillators, but the intended use for switched internal paddle remains functionally unchanged.

The Switched Internal Paddles are intended for use with HeartStart defibrillators to defibrillate the heart during open-chest surgical procedures.

Indications for Use:

The Switched Internal Paddles are indicated for use in the treatment of ventricular fibrillation by manual defibrillation being provided directly to the heart during open-chest surgical procedures.

VI. Comparison of Technological Characteristics with the Predicate Device

The intended use and technology used with the Switched Internal Paddles remains unchanged by the labeling modifications for reprocessing internal paddles. Table 5-3 below provides a summary of comparison between the Switched Internal Paddles that is the subject of this 510(k) and the primary predicate device Switched Internal Paddles included with HeartStart XL Defibrillator/Monitor cleared per K021453.
