Regulatory Classification

Identification

A piston syringe is a device intended for medical purposes that consists of a calibrated hollow barrel and a movable plunger. At one end of the barrel there is a male connector (nozzle) for fitting the female connector (hub) of a hypodermic single lumen needle. The device is used to inject fluids into, or withdraw fluids from, the body.

### Comment #1

The subject device does not have a needle safety feature, but has a disc on the plunger which could be stuck by the buckle of the syringe to prevent re-use of the syringe. The subject device and the predicate device both have the same intended use, this difference does not affect the clinical safety of the subject device.

# Comment #2

The subject device and the predicate device are both syringes that render the syringe unusable after injection, the predicate device also has a needle safety feature.

# Comment #3

The subject device is available in gauges 18g-30g and the predicate device is available in 21g-28g. Performance testing was done per ISO 9626 and ISO 7864 done to demonstrate that the differences in needle gauges do not affect the clinical safety or

{7}------------------------------------------------

effectiveness of the devices.

## Comment #4

The bevel of subject device is different from the predicate device. However, this difference does not affect intended use. The difference was addressed through ISO 9626 and ISO 7864. Therefore, the differences on bevel do not raise different question of safety and effectiveness.

# Comment #5

The material of subject device is different from the predicate device. The piston of subject device is silicone rubber while the predicate device is isoprene rubber. And the configurations of subject device do not include Needle Sheath compared with predicate device, which does not affect its intended use and does not introduce new materials. However, biocompatibility testing was performed with the subject device and found it to be biocompatible. Therefore, the differences on materials do not raise new questions about safety and effectiveness.

## VIII Performance data

The following performance data were provided in support of the substantial equivalence determination.

# Biocompatibility testing

# IX Conclusion

The differences between the predicate and subject device do not raise any new or different questions of safety and effectiveness. The Sterile Auto-Disable syringes with/without needle for single use are substantially equivalent to The Safety Auto-Disable Syringe with Needle (Auto-Lock) with respect to indications for use, target population, and technological characteristics.
