#### Name of Device.
Trade Name: BT37 Incubator Common Name: IVF Incubator Classification Name: Assisted Reproduction Accessory (21 CFR §884.6120) Product Code: MQG
### Predicate Device:
COOK Mini-Incubator (510(k) Number: K983642)
#### Device Description:
The BT37 Incubator has been designed as a bench-top incubator to provide a electronically controlled environment (temperature and humidified-gas (premixed gas; typically 6% CO2, 5% O2, balance N2)) for use in cell culture as part of In Vitro Fertilization (IVF) / Assisted Reproductive Technology (ART) treatments.
The BT37 Incubator overall dimensions are 420mm wide x 270mm deep x 210mm high, with a weight of 15,5 kg.
The BT37 Incubator has two chambers each of which have been designed to hold a variety of dishes with a maximum capacity per chamber as follows:
| IVF Petri Dish* | Number per Chamber |
|-----------------|--------------------|
| NUNC 4 well | 4 |
| NUNC 60 mm | 4 |
| NUNC 35 mm | 10 |
| MINITUB 5 well | 4 |
| FALCON 60 mm | 4 |
*This list is an example of available IVF dishes.
In case of external power failure, the BT37 incubator is equipped with an internal backup battery to maintain functionality for up to 120 minutes.
{1}------------------------------------------------
The BT37 Incubator provides an environment with elevated humidity by bubbling the incoming gas through a heated humidification bottle containing water. This gas this then passed to the left and right incubation chambers.
In its default configuration, the BT37 normally provides gas at a constant flow rate of 30 mL/min. After closing the lids, an increased gas flow at 360 ml./min is provided for 3 minutes to purge the systems. After fitting a new bottle, a triple length purge of 360 ml /min for 9 minutes is provided.
An alternative pulsed flow regime is available, where the normally constant flow of 30 mL/min can be replaced by a flow that pulses between a high and low rate. The default for these settings are normally 60 mL/min and 20 mL/min respectively with a time ratio designed to provide a mean flow of 30 mL/min. This flow approach is not normally used.
#### Indication for Use:
The Planer BT37 Incubator is intended to be used to provide an environment with controlled temperature at or near body temperature, CO2, O2 and N2 gases, and elevated humidity for the development of gametes and embryos during in vitro fertilization (IVF) / assisted reproductive technology (ART) treatments.
#### Substantial Equivalence:
The Planer BT37 Incubator is substantially equivalent with respect to the intended use of the published predicate device description and technological characteristics: a dual chamber format is used; each chamber is independently controlled (temperature); the same gasses are used; the same process of supplying the gasses is used; and an equivalent humidification process is used. In both the predicate device and the BT37 Incubator, a filter is used on the humidification bottle to filter contaminates from the gas and prevent it entering the chambers.
From the viewpoint of the dishes used with the device, the two units are equivalent. The Primary differences are in the technologies used to control the gas flow and the temperatures, and the design of the user interface.
The BT37 Incubator provides the following features that are different from those found on the predicate device. Note that these features do not alter the fundamental function of the equipment and do not impact on the safety of the device.
The unit incorporates an external communication port that enables remote monitoring of the system.
The unit incorporates an inlet routing guide to ensure that the tube routing from the humidification bottle to the chambers is controlled, repeatable and not subject to temperature changes that could cause excessive condensation in the tubes.
The unit incorporates a two line liquid crystal display (LCD) allowing different parameters to be viewed.
The gas flow through the humidification bottle is visible via the front panel which allows visual feedback that the system is operating.
510(k) Number (if known):
{2}------------------------------------------------
The unit provides a pulsed-flow feature that is not available on the predicate device. In normal use, non-pulsed, both the predicate device and the BT37 Incubator provide a constant flow of 30 mL/min shared between the left and right-hand sides of the incubator. In the BT37 incubator's pulsed-flow mode, the BT37 incubator maintains a mean flow by alternating between a low flow rate and a high flow rate. The default flow pattern is 20 ml/min for 900 s followed by 60 mL/min for 300 s which results in a mean flow of 30 mL/min; identical to that provided using the normal non-pulsed operating mode.
A summary of the device comparison is shown in the table below.
