HIGH-PRESSURE SYRINGE WITH PRESSURE REDUCTION

摘要

Devices used to pressurize, depressurize, or otherwise displace fluid are disclosed. The devices may be configured as a syringe. The syringe may be configured to generate high-pressure within the syringe to inflate or deflate a medical device, such as a balloon, or to inject a substance, such as bone cement, into a bone, such as a vertebra. The syringe may include a pressure reduction mechanism used to depressurize the syringe.
