A system for delivering bone cement into a bone is provided. The system can include a hydraulic system actuatable to deliver a bone cement mixture from a bone cement container, through a cannula and into a bone. The hydraulic system can have more than one pressure relief mechanism for decreasing pressure in the hydraulic system to cease delivery (e.g., substantially instantaneously) of the bone cement into the bone.

Bone treatment systems and methods

Tumor ablation devices and related systems and methods are disclosed. Some tumor ablation devices include an RF energy delivery probe with two conductors and one or more thermocouples. The thermocouple measures a temperature at a location on one of the conductors. A generator can produce a current to be conducted between the first conductor and the second conductor via tissue within a desired ablation region. The ablation regions created by the RF energy delivery probe are symmetric about poles of the first conductor and the second conductor. A distal portion of the RF energy delivery probe may articulate, enabling a user to position the RF energy delivery probe in a proper position to ablate the tumor. The thermocouples may be disposed on a flexible or wired thermocouple circuit that is disposed between insulators.
