  • Patent number: 10695117
    Abstract: Systems and methods for treating vertebral compression fractures are provided. A kit can include at least one body containing a bone cement precursor to be mixed with at least one other bone cement precursor to form a bone cement. The body or a package containing the body can include at least one sensor. In some embodiments the sensor can be a temperature sensor.

  • Publication number: 20190167328
    Abstract: Systems and methods for treating vertebral compression fractures are discussed. In an embodiment, a method includes mixing bone cement precursors thereby causing a first chemical curing reaction characterized by a first time-viscosity profile, controllably applying energy to the bone cement from an external source to modify the first time-viscosity profile to a second time-viscosity profile, and injecting the cement into bone at a substantially constant viscosity greater than about 1000 Pa·s to greater than about 5000 Pa·s over an extended working time. In another embodiment, a bone cement injector system is provided that includes a first handle component that is detachably coupled to a second sleeve component having a distal end for positioning in bone and a flow channel extending through the first and second components. The system includes first and second thermal energy emitters for delivering energy to bone cement flows in a flow channel portion in the first and second components, respectively.

  • Patent number: 10080817
    Abstract: The present disclosure relates to bone cement formulations that have an extended working time for use in vertebroplasty procedures and other osteoplasty procedures together with cement injectors that include energy delivery systems for on-demand control of cement viscosity and flow parameters. The bone cement formulations may include a liquid component having at least one monomer and a non-liquid component including polymer particles and benzoyl peroxide (BPO). The non-liquid component may be further configured to allow controlled exposure of the BPO to the liquid monomer so as to enable control of the viscosity of the bone cement composition.

  • Patent number: 10039584
    Abstract: A system for use in combining two part preparations, such as bone cement, can include a chamber for intermixing liquid and powder components, a container, a vacuum channel, and a filter. The mixing chamber can be configured to hold a non-liquid, polymer powder component of a bone cement. The container can be configured to hold a liquid component of the bone cement. The vacuum channel can direct a partial vacuum to draw the liquid component from the container into the non-liquid component in the mixing chamber to intermix the components and to thereby provide a settable bone cement.

  • Patent number: 9901657
    Abstract: A system for use in bone cement preparation can include a chamber for intermixing a liquid monomer and solid polymer components, a container, a vacuum channel, and a filter. The mixing chamber can be configured to hold a non-liquid, polymer powder component of a bone cement. The container can be configured to hold a liquid component of the bone cement. The system can have a first interface disposed between the mixing chamber and the container and a second interface disposed between the mixing chamber and the vacuum channel. The second interface can to receive and position the filter between the mixing chamber and the vacuum channel. The vacuum channel can direct a partial vacuum to draw the liquid component from the container into the non-liquid component in the mixing chamber to intermix the components and to thereby provide a settable bone cement.

  • Publication number: 20150356643
    Abstract: Embodiments of the present disclosure provide methods and systems for anonymizing the identity of users of an online system. A request to interact with the online system is received from a viewing user. A determination is made whether the request is for interacting with another user of the online system. If the request is to interact with another users, the online system uses the real identity of the viewing user for the interaction. Otherwise, if the request is not for interaction with another user of the online system, the online system uses an anonymized identity of the viewing user.
