## Indications for Use

The Stockert SCP Rhythm is an accessory to the S3 Cardiopulmonary Bypass Console that allows for cyclically controlled delivery of blood with the Stöckert SCP during cardiopulmonary bypass for periods of up to six hours.

## Device Story

Stöckert SCP Rhythm is a modified version of the S3 Cyclic RPM Control Module; functions as an accessory to the S3 Cardiopulmonary Bypass Console. Device provides cyclically controlled blood delivery during cardiopulmonary bypass procedures. Modifications from predicate include updated display panel artwork and firmware/software changes; hardware and electronics remain unchanged. Used in clinical settings during bypass surgery; operated by perfusionists or clinical staff. Output consists of controlled pump speed cycles to manage blood flow. Benefits include precise control of blood delivery during bypass for up to six hours.

## Clinical Evidence

Bench testing only; no clinical data provided. Verification and validation of firmware/software modifications performed to demonstrate substantial equivalence.

## Technological Characteristics

Accessory to S3 Cardiopulmonary Bypass Console; firmware/software-controlled pump speed regulation. No hardware or electronic modifications from predicate. Sterilization and material specifications not detailed beyond reference to existing S3 console components.

## Regulatory Identification

A cardiopulmonary bypass pump speed control is a device used that incorporates an electrical system or a mechanical system, or both, and is used to control the speed of blood pumps used in cardiopulmonary bypass surgery.

## Predicate Devices

- Stöckert S3 Cyclic RPM Control Module ([K971520](/device/K971520.md))

#### 2. DEVICE NAME

Stöckert SCP Rhythm Proprietary Name: Common/Usual Name: Cyclic RPM Control Accessory to cardiopulmonary bypass console Classification Name:

#### 3. PREDICATE DEVICE

Stöckert S3 Cyclic RPM Control Module (K971520)

#### 4. DEVICE DESCRIPTION

The Stöckert SCP Rhythm is a modification of the S3 Cyclic RPM Control Module. The modifications consist of two changes: ( 1 ) a change to the artwork of the display panel to show SCP Rhythm rather than Cyclic RPM Control and (2) firmware and software modifications. No modifications are being made to the hardware or electronics of any of the components. The Stöckert SCP Rhythm is intended for use with the SCP System as mounted on an S3 Cardiopulmonary Bypass Console.

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

#### న. INTENDED USE

The Stockert SCP Rhythm is an accessory to the S3 Cardiopulmonary Bypass Console that allows for cyclically controlled delivery of blood with the Stöckert SCP during cardiopulmonary bypass for periods of up to six hours.

#### TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE 6.

The proposed Stöckert SCP Rhythm is identical in intended use and fundamental scientific technology to the parent Stöckert S3 Cyclic RPM Control. The differences between the proposed and parent device are limited to the display panel and firmware/software. Stöckert Instrumente GmbH has verified and validated the device modifications and has demonstrated, through the testing provided in the 510(k), that the Stöckert SCP Rhythm complies with specifications, meets user requirements, and the differences between the parent and the proposed device do not raise new issues of safety or effectiveness.
