The device description explicitly lists multiple hardware components including a chassis, shroud, transaxle, seat, controller, batteries, battery charger, tiller handle, and potentiometer throttle control.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for providing transportation to disabled or elderly individuals. This is a mobility aid, not a device used to examine specimens derived from the human body for the purpose of providing information for diagnosis, monitoring, or treatment.
- Device Description: The description details a motor-driven scooter with components related to mobility (chassis, transaxle, seat, controller, batteries, etc.). There is no mention of reagents, calibrators, controls, or any other components typically associated with IVD devices.
- Lack of IVD-related information: The document does not mention any aspects related to sample collection, analysis of biological specimens, or diagnostic purposes.
Therefore, the Esteem scooter is a medical device, but it falls under the category of a mobility aid, not an In Vitro Diagnostic device.

Intend use of device
Esteem scooter is intended for an indoor/outdoor scooter that provides transportation for disabled or elderly person limited to a seated position.
Device description:
The Esteem invalid scooter is motor driven, indoor transportation vehicles with the intended use to provide mobility to disabled or elderly person limited to a seated position.
The Esteem invalid scooter consist of a chassis, shroud, transaxle, seat, controller, batteries, and battery charger. It also includes a tiller handle for steering and a thumb or finger operated potentiometer throttle control level to engage and disengage the scooter motion in both the forward and reverse directions.
The scooter is powered by two 12 volt 28ah sealed lead-acid (AGM or Gel type) batteries with 19 miles range. The maximum speed is up to 6mph. The rigid chassis features an advanced design that weight distribution resulting in dynamic performance that greatly improves safety and ride comfort
Chassis:
、
...
Abstract: The advanced chassis has 4 wheel suspension and the batteries are mounted low and at the front to create the ideal 50:50 static weight distribution and lower the centre of gravity thereby providing greater safety and improving the ride and steering characteristics of the scooter.
There is a battery tray area near the front of chassis. Ahead of this are mounts for the front upper and lower suspension arms.

The front upper and lower suspension arms are shaped in such a way as to come around the battery tray area and back along the battery tray area so that the stub axles are behind the of the batteries. The joining of the front and rear chassis pieces is automatic, electrically and mechanically, allowing easy separation of the scooter for easy transport and storage. The rear chassis with independent rear suspension provides greater resistance to sideways tipping and provides superior traction and ride comfort.
Seat and seat base:
The seat base sits on four seat posts providing great stability. The two armrests are adjustable for width and height to suit different size persons. Arnrests can be raised up and out of the users way to allow easy access. The seat can be also swiveled for easy access. The seat height is also adjustable. The seat can also be adjusted forward and back on a sliding base. The back rest can be inclined as required. The seat has molded foam over 4 seat springs for improved comfort. The seat material is automotive vinyl for durability and ease of cleaning.
Shroud:
The body shroud is Ist grade ABS plastic coated with automotive 2 pack epoxy paint finish in a variety of colors.
Lights:
The lights meet with EUR road regulations. There is a front headlight mounted 550mm above the ground and two front indicators, there are two rear stop lights and two rear indicators and two rear reflectors in red. .
Transaxle and brake
A DC electric motor supplies power to the scooter through a three stage gear reduction, differential assembly and drive shafts to both rear wheels. An electro magnetic brake is attached to the shaft to provide positive braking. The braking function is applied when no electric current passes its inductive when the speed control throttle is activated. The scooter will stay firmly on a slope of greater than 15degrees without slipping. There is a brake released under the rear that can be manually operated only when off the scooter should the user have the scooter. An inhibit switch and control prevent the scooter from being ridden whilst the brake is disengaged
Batteries:
There are two Panasonic deep cycle SLA (AGM) 28ah 12-volt deep cycle rechargeable batteries usually supplied with the scooter. These batteries are designed for this application and are proven to provide long range and long life. Other batteries of similar specification may also be fitted as replacement parts with no adverse effect.
Electronic control and dash panel:
The speed of the scooter is controlled by an electronic control system. The Estem is 6 miles per hour . The scooter uses the Curtis PMC controller American Tech, made in China, that is widely used in powered invalid scooters all over the world. There is HPD feature which prevents the scooter from driving should the user turn on the key whilst unknowingly operated the throttler is the most advanced known to us and incorporates many safety and operational overrides, regardless of operator input. It also features many self diagnosis features and is very reliable in service. It meets all EMI requirement ) The modern dash console has a battery indicator to show the state of battery energy, a potentiometer to set desired maximum speed, a high and low power switch, two easily accessible horn buttons, a headlight switch and toggle switch for right and left turning indicators. A LCD display has a speedometer, odometer and trip meter greatly enhancing the users experience and providing data for servicing.
Freewheel:
A lever under the rear of the scooter can be pulled down to release the electro magnetic brake to allow the scooter to be pushed. The controller can sense this and will not allow the scooter with the brake released. Further the controller can sense the speed at which the scooter is moving when the brake is released and this is regulated to a maximum speed of 3mph thus preventing possible overrun down a steep slope. Also the lever is designed in such a way as to prevent accidental release should the rider drive over an unusual obstacle.

Substantial equivalence:
The Esteem scooter has the same intended use and similiar technology characteristics as the Victory 4 wheel scooter. K071949 The non clinical testing and the predicate comparisons show that the differences in design and technologies do not raise any new questions of safety or effectiveness. Moreover the variations in design in fact lead to the Esteem scooter being a safer and more stable scooter. The Esteem scooter is substantially equivate device. The Esteem scooter has passed all testing requirements and is considered to be safe for the user to operate. Furthermore the Esteem scooter has been in the Australian market since 2003 with no adverse outcomes or safety related issues having been detected.
