摘要： The present disclosure relates to a connector for medical devices. The connector may have two interfaces facing different planes. The two interfaces may provide access to the connector's core and hub. The hub may be free to rotate relative to the core to increase accessibility and/or angle attachment while maintaining a fluid pathway between the core and the hub.

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.

摘要： The present disclosure illustrates an osteotome for treating hard tissue and methods of use. The osteotome embodiments described herein include a shaft with a working end configured to displace hard tissue and a lumen to deliver material through the shaft. The working end may create pathways by selectively transitioning from a linear to a non-linear configuration. The lumen may deliver material through the shaft while the working end is in a linear or a non-linear configuration allowing precise filling of the pathways.

摘要： Spinal tumor ablation devices and related systems and methods are disclosed. Some spinal tumor ablation devices include electrodes that are fixedly offset from one another. Some spinal tumor ablation devices include a thermal energy delivery probe that has at least one temperature sensor coupled thereto. The position of the at least one temperature sensor relative to other components of the spinal tumor ablation device may be controlled by adjusting the position of the thermal energy delivery probe in some spinal tumor ablation devices. Some spinal tumor ablation devices are configured to facilitate the delivery of a cement through a utility channel of the device.

摘要： Medical devices for creating or expanding a cavity within bone of a patient are disclosed. In some circumstances, a medical device, such as an osteotome is designed to facilitate simultaneous advancement and articulation of a distal portion of the osteotome. Simultaneous advancement and articulation of the distal portion may reduce one or more forces on the distal portion of the osteotome relative to other methods in which advancement and articulation are separated in time, thereby decreasing the risk of breakage or other damage to the osteotome.

摘要： Medical devices such as osteotomes are provided. The medical device may include inner and outer members that form a working end portion. Distal end portions of the inner and outer members can cooperate to allow deflection of the working end portion. Medical devices including indicators are also provided. The indicator may communicate a direction of deflection of the working end portion to a practitioner. Additionally, medical devices including torque release mechanisms are provided. The torque release mechanism may uncouple a first portion of the medical device from a second portion of the medical device when an amount of torque applied to the medical device exceeds a predetermined value. The torque release mechanism may limit damage to components of the medical device during use of the medical device.
