Description of Device & Intended Use

Heartstream electrode adapters serve as an interface to allow Heartstream electrodes to be connected to various manual defibrillators for external cardiovascular pacing as well as monitoring and delivery of defibrillation shocks up to 360J.

Heartstream electrode adapters are made of rigid thermoplastic material (or equivalent), with varying configurations depending upon the manual defibrillator for which they are designed. The adapters will be provided as reusable stand-alone accessories (to be used in conjunction with standard Heartstream electrodes) or preattached to a Heartstream electrode set, for single use.

{1}------------------------------------------------

Technological Characteristics

All Heartstream electrode adapters are designed to comply with applicable portions of relevant standards. including:

  • IEC 601-1, Medical electrical equipment, Part 1: General requirements for safety, 1993 .
  • IEC 601-2-4, Medical electrical equipment, Part 2: Particular Requirements for the Safety of Cardiac . Defibrillators and Cardiac Defibrillator/Monitors, 1993
  • IEC 601-2-25, Medical electrical equipment, Part 2: Particular requirements for the safety of . electrocardiographs
  • ANSVAAMI DF39-1993. Automatic external defibrillators and remote-control defibrillators. . September 16, 1993

Testing per these standards demonstrated that the Heartstream electrodes effectively deliver defibrillation energy up to 360J, allow for external transcutaneous cardiac pacing, demonstrate mechanical and electrical compatibility with manual defibrillators, and minimize safety risks to the user and patient.

Summary of Substantial Equivalence

Heartstream electrode adapters were evaluated in terms of indications for use, technological characteristics and materials, and compared to equivalent devices currently on the market.

The Heartstream electrode adapter is very similar in form, fit and function to other comparable devices. Marketed adapters and adapter cables typically gonsist of two connectors (or a double-sided connector) joined by an insulated conductor or cable of varying length. One connector (or one side of the connector) fits into the connector socket of the defibrillator, while the other attaches to the proximal end of the electrode set. The connectors are typically made of a rigid thermoplastic material. Adapters and adapter cables are designed so that both connectors are firmly seated when in use, and so they, do not expose a user to a risk of accidental electrical contact. They are also designed to ensure that all pacing, monitoring and/or defibrillation functions are not adversely affected by their placement. These characteristics apply to both the stand-alone Heartstream electrode adapter and the Heartstream electrodes with a preattached adapter.

Heartstream electrodes with a preattached electrode adapter are substantially equivalent to the standard Heartstream electrodes regarding device design and usage for defibrillation, and Katecho K-Defib/Pace multifunction electrodes regarding device design and usage for defibrillation, monitoring and pacing.

Heartstream stand-alone electrode adapters are substantially equivalent to the Darox R2 series of adapter cables regarding device design and use as an interface between electrodes and defibrillators for defibrillation, monitoring and pacing, for use with numerous defibrillators.

Therefore, due to the similarity of design features, and the similarity of the indicated use to other predicate devices, Heartstream, Inc. believes this product does not raise any new safety or effectiveness issues.
