## Indications for Use

The URok Rocking Wheelchair is intended to provide mobility to persons limited to a sitting position while the rocking mechanism is locked in an upright position. The wheelchair is intended to redistribute pressures exerted on the buttocks and lower back when rocking or tilted at an angle. The wheelchair is intended to provide comfort adjustment while rocking or tilted at an angle.

## Device Story

Manually operated, attendant or user-propelled mechanical wheelchair; aluminum TIG-welded frame; padded sling seat. Features: rocking motion via two fiberglass leaf springs under seat center of gravity; tilt-in-space capability. Rocking initiated by user head movement; arc limited by anti-tippers and rock arrestors. Rocking/tilt locked via cable-controlled pins operated by bicycle-style brake levers on push handles. Used in indoor/outdoor settings for mobility, pressure relief, and positioning. Benefits: dynamic pressure management, comfort, and head control. Healthcare providers (therapists) evaluate patients for appropriate use.

## Clinical Evidence

Bench testing only. Device performance verified against ANSI/RESNA WC series requirements. Pressure redistribution efficacy during rocking observed and recorded using adult human volunteers on a pressure recording mat.

## Technological Characteristics

Manual, mechanical wheelchair. Materials: aluminum tubing frame, fiberglass leaf springs, padded sling upholstery (ISO 7176-16 compliant). Sensing/Actuation: mechanical leaf springs for rocking; cable-actuated pins for locking/tilt. Dimensions: rigid, non-folding. Connectivity: none. Sterilization: N/A.

## Regulatory Identification

A mechanical wheelchair is a manually operated device with wheels that is intended for medical purposes to provide mobility to persons restricted to a sitting position.

Common or Usual Name: Manual Wheelchair

Classification Name:

Wheelchair, Mechanical 89IOR

### Predicate Devices:

The URok Rocking Wheelchair is substantially equivalent to the RxRocker (K902438) wheelchair for the rocking feature.

The URok Rocking Wheelchair is substantially equivalent to the Invacare Solara wheelchair for the pressure redistribution feature.

#### Background

In 2001 AMG Medical Inc. purchased all rights to the RxRocker Corp. with the exception of the following: AMG granted RxRocker Corp. the right to continue to sell the RxRocker only to the US Government (including the Veteran's Administration and US military hospitals under the patents and existing technology and know how found the RxRocker wheelchair.

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

In consideration of the above sales agreement and continuing sales of the original 510k device, AMG is not submitting this 510k for a change to an existing device but rather submitting for a new 510k premarket approval referencing the RxRocker as a predicate device.

# Intended Use:

The URok Rocking Wheelchair is intended to provide mobility to persons limited to a sitting position while the rocking mechanism is locked in an upright position.

The wheelchair is intended to redistribute pressures exerted on the buttocks and lower back when rocking or tilted at an angle.

The wheelchair is intended to provide comfort adjustment while rocking or tilted at an angle.

# Technological Characteristics

The AMG Medical Inc. URok Rocking Wheelchair is a manually operated, attendant or user propelled, mechanical rocking wheelchair. The device is a lightweight wheelchair, suitable for both indoor and outdoor use.

The device consists of an aluminum frame, one size of rear wheel, and smaller front pivoting casters for steering and turning. The frame is constructed from aluminum tubing that is TIG-welded. This device is a rigid, non-folding type of wheelchair that incorporates a padded, sling style seat. The upholstery meets the requirements of ISO 7176-16, flammability standards.

The AMG URok Rocking Wheelchair includes a rocking feature which permits dynamic pressure management of the seating pressure upon the buttocks. The rocking feature is realized by the placement of two vertically positioned fibrogless Ieaf springs, which are connected to the seat and frame, under the seat's centre of gravity. The balance of the seat upon the springs is precise enough so that the rocking motion may be initiated by the user simply by gently moving the head backward and forward. Safety features such as anti tippers and rock arrestors limit the arc of the rocking motion. The rocking feature can be "locked out" by an attendant so that the device can be used as a wheelchair with no rocking motion.

The AMG URok wheelchair also has a "tilts in space" feature. The rocking mcchanism can be locked in multiple positions to provide "tilt in space" that permits receing meemainst backwards thereby allowing gravity to hold them in position. This is used to help in positioning, comfort, or head control. The tilt in space is initiated by the attendant pushing down on the push handles to tilt the scat and back and locking out the rocking action when the desired angle of tilt is reached.

The rocking feature is released or is locked out by two cable controlled pins that insert into holes within two vertically mounted metal plates located under the seat support tubes. The cables are controlled using bicycle brake type levers in onto bed on the rear push tube or handle.

# Substantial equivalence:

The AMG URok Rocking Wheelchair is substantially equivalent to numerous manual, mechanical wheelchairs currently in the marketplace, for which FDA has granted marketing clearance through the 510(k) premarket notification process. More specifically the AMG rocking wheelchair is substantially equivalent to the RxRocker (K902438) wheelchair for it's rocking feature and to the Invacare Solara wheelchair for it's pressure redistribution feature.

Each of the products is manually operated, attendant or user propelled with the same intended functions and uses which are to provide mobility to persons that may be limited to a seated position and to provide pressure relief. Additionally, in one wheelchair pressure relief is achieved either by rocking or by "tilt in space" (URok Rocking Wheelchair) and in the other wheelchair pressure redistribution is achieved solely by "tilt in space" (Invacare Solara).

# Performance data:

The AMG URok Rocking Wheelchair meets the performance requirements specified in the ANSI/RESNA WC series of wheelchair requirements.

Pressure redistribution obtained while rocking was observed and recorded using adult human volunteers seated on a pressure recording mat placed upon the seat cushion.
