Intended Use

The NOMOS Motorized CRANE II is intended to be used as an accessory to powered radiation therapy patient support tables. The NOMOS Motorized CRANE II verifies and describes, via a set of Z and X coordinates, the set-up of the table/patient prior to treatment.

Device Story

Accessory to powered radiation therapy patient support tables; attaches via interface plate to stationary base and clamps to table accessory rails. Uses precision ball screw drive mechanisms (Z and X axes) powered by electric motors to position table top. Operator interface via touch screen panels (on-device and remote). Displays table position; allows operator to initiate movement. Retains manual hand cranks for backup; includes battery-powered digital scales for independent position verification. Used in treatment control room/clinic by radiation therapy staff. Benefits patient by ensuring accurate table positioning prior to radiation delivery.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Powered radiation therapy patient support assembly. Materials equivalent to predicate. Precision ball screw drive positioning mechanisms for Z and X axes. Electric motor actuation with manual hand crank backup. Battery-powered digital scales for independent position verification. Touch screen operator interface. Software controls for positioning. Accuracy: +/- 0.1 mm (Z-axis), +/- 0.4 mm (X-axis). Range: 300 mm per axis.

Indications for Use

Indicated for use as an accessory to powered radiation therapy patient support tables to verify and describe the set-up of the table/patient position prior to treatment.

Regulatory Classification

Identification

A powered radiation therapy patient support assembly is an electrically powered adjustable couch intended to support a patient during radiation therapy.

NOMOS CRANE II (K991966) B. Name of predicate device:

- Class II C. Classification:
- D. Performance Standards: None established
- E. Intended Use and Device Description:

Intended Use:

The NOMOS Motorized CRANE II is intended to be used as an accessory to powered radiation therapy patient support tables. The NOMOS Motorized CRANE II verifies and describes, via a set of Z and X coordinates, the set-up of the table/patient prior to treatment.

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

#### Device Description:

The NOMOS Motorized CRANE II is a powered version of the manual NOMOS CRANE II. It is an accessory to radiation therapy patient support tables.

Like the NOMOS CRANE II, the Motorized CRANE II attaches to the stationary base Elle the NOWOO OF through a permanently installed interface plate and clamps to the accessory rails of the moveable table top. The Motorized CRANE II can be the acod from the treatment table when its use is not required, leaving only the interface plate remaining on the stationary base of the treatment table.

The Motorized CRANE II uses precision ball screw drive positioning mechanisms (one for the Z-axis and one for the X-axis) to position the table top relative to the stationary base of the treatment table.

While these positioning mechanisms retain the small hand cranks employed in the predicate CRANE II to allow manual operation when needed, the primary drive force is provided by two electric motors – one for each axis of movement. These motors le provided and operator interface is provided through two touch screen are ooltware oon. One located on the device and one remote panel that can be placed in the treatment control room.

The control panels display the position of the patient treatment table, and allow the operator to specify and initiate movement in the Z and X axes. Using the NOMOS CRANE II, the operator can move the treatment table over a range of 300 mm in each axis. When attached to a treatment table loaded to a maximum weight of 300 ounds, the NOMOS Motorized Crane II is capable of +/- 0.1 mm accuracy in the Zaxis, and +/- 0.4 mm accuracy in the X-axis.

The Motorized CRANE II retains the battery-powered digital scales from the Crane II as an independent means of position verification.

## F. Summary of Substantial Equivalence

### Indications:

The indications for the NOMOS Motorized CRANE II are the same as for the predicate device, the NOMOS CRANE II; that is, to verify and describe the set-up of the table/patient position prior to treatment.

## Design:

The design of the NOMOS Motorized CRANE II is equivalent to the NOMOS CRANE II, with the addition of electric drive motors, operator interface displays, and software controls.

{2}------------------------------------------------

### Materials:

The materials used in the NOMOS Motorized CRANE II are equivalent to those used in the predicate NOMOS CRANE II.

### Manufacturing:

The manufacturing processes used in the production of the NOMOS Motorized CRANE II are equivalent to those used in the manufacture of the predicate NOMOS CRANE II and are performed at the same facility.

### Specifications:

The operating specifications of the NOMOS Motorized CRANE II are equivalent to the predicate NOMOS CRANE II, particularly with respect to range of movement and accuracy.

### Conclusions:

The addition of electric motors and software controls to the design do not raise any new issues relating to safety and effectiveness. NOMOS thus considers the now loads follang to SNE II to be substantially equivalent to the predicate device the NOMOS CRANE II.

#### Note:

Any statement made in conjunction with this submission regarding substantial equivalence to any other product only relates to whether the product can be legally marketed according to FDA regulations and is not relevant evidence in patent infringement litigation. As the Commissioner of the FDA has indicated, " . . a determination of substantial equivalence under the Federal Food, Drug, and Cosmetic Act relates to the fact that the product can lawfully be marketed without premarket approval or reclassification. This determination is not intended to have any bearing whatsoever on the resolution of patent infringement suits." 42 Fed. Reg. (1977).
