Intended Use

The RapidBlue™ System is a thermal regulating system intended to induce, maintain and reverse mild hypothermia in neurosurgical patients in surgery and in recovery/intensive care, to achieve and/or maintain normothermia in cardiac surgery patients in surgery and in recovery/ intensive care, and for use in fever reduction, as an adjunct to other antipyretic therapy, in patients with cerebral infarction and intracerebral hemorrhage who required access to the central venous circulation and who are intubated and sedated.

Device Story

RapidBlue™ System is a thermal regulating system comprising a console, sterile cassette, and endovascular catheter. Console contains refrigeration/heating elements, heat exchanger, pump, and control software. Sterile cassette connects console to catheter for closed-loop circulation of heat transfer fluid. Catheter (10.7F to 14F) features distal heat exchange element for blood cooling/warming. System operates via two modes: one using conventional YSI-400 esophageal temperature probes and one using integrated catheter temperature sensor. Used in OR and ICU settings by clinicians to manage patient temperature. Output provides thermal regulation to induce/reverse hypothermia or maintain normothermia, aiding clinical management of neurosurgical, cardiac, and stroke patients.

Technological Characteristics

System includes console with refrigeration/heating, pump, and heat exchanger. Catheter diameters: 10.7F to 14F. Materials are biocompatible per ISO 10993-1. Closed-loop fluid circulation. Supports external YSI-400 esophageal probes or integrated catheter temperature sensors. Software controls system operation.

Indications for Use

Indicated for neurosurgical patients (surgery/ICU) for mild hypothermia; cardiac surgery patients (surgery/ICU) for normothermia; and intubated/sedated patients with cerebral infarction or intracerebral hemorrhage requiring central venous access for fever reduction as an adjunct to antipyretic therapy.

Regulatory Classification

Identification

A thermal regulating system is an external system consisting of a device that is placed in contact with the patient and a temperature controller for the device. The system is used to regulate patient temperature.

## Device Name

Trade or Proprietary Name: RapidBlue™ System

Common or Usual Name: Thermal Regulating System

Classification Name: Thermal Regulating System

## Predicate Devices

The subject device is substantially equivalent, in whole or in part, to predicate devices manufactured by INNERCOOL therapies (K033623).

## Device Description

The subject device is a thermal regulating system consisting of three (3) parts:

- 1. A console containing refrigeration/heating elements, a heat exchanger to cool and warm the circulating fluid, a pump to circulate that fluid, and controls and software necessary to operate the system.

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

- 2. A sterile cassette to connect the console to the catheter, and through which the heat transfer fluid is circulated to and from the catheter in a closed-loop manner.
- 3. An endovascular catheter having a heat exchange element at the distal end, through which a thermal transfer fluid is circulated to cool or warm the blood, and which is available in various diameters from 10.7 french to 14 french.

The modified system offers a mode, which uses conventional, off-the-shelf temperature probes such as YSI-400 esophageal probes, to monitor patient temperature and control system operation, and one mode that uses an integrated temperature sensor in the catheter.

## Intended Use

The RapidBlue™ System is a thermal regulating system intended to induce, maintain and reverse mild hypothermia in neurosurgical patients in surgery and in recovery/intensive care, to achieve and/or maintain normothermia in cardiac surgery patients in surgery and in recovery/ intensive care, and for use in fever reduction, as an adjunct to other antipyretic therapy, in patients with cerebral infarction and intracerebral hemorrhage who required access to the central venous circulation and who are intubated and sedated.

# Comparison to Predicate Devices

The subject device has the same, or equivalent, indications for use as do other thermal regulating systems cleared for commercial distribution in the U.S .;

The subject device has the same or equivalent design characteristics as other thermal regulating systems cleared for commercial distribution in the U.S .;

The subject device is composed of biocompatible materials meeting the requirements of ISO 10993-1, as are other devices cleared for commercial distribution in the U.S .;

The subject device has equivalent performance in inducing and reversing hypothermia, and in maintaining normothermia, as do other thermal regulating systems commercially available in the U.S.

Dear Ms. Spinella:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
