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. In some methods, data from the sensor can be used to determine certain parameters related to a treatment interval involving the bone cement.
Claims20
A bone cement kit package, comprising:
- a first container containing a liquid component comprising a monomer;
- a second container containing a non-liquid component comprising at least two polymer bead populations having different average sizes and different weight percentages of a radical initiator,
- wherein the liquid component and the non-liquid component are configured to, upon mixing, form a mixture that cures at least in part by self-heating by undergoing an exothermic reaction;
- and
- a temperature sensor affixed to the bone cement kit package and configured to indicate a pre-mix temperature.
A system for providing a bone cement for injection into a patient, comprising:
- a bone cement kit package including a first package containing a liquid monomer component and a second package containing a non-liquid polymer component comprising at least two polymer bead populations having different average sizes and different weight percentages of an initiator;
- a temperature sensor affixed to the bone cement kit package and configured to indicate a pre-mix temperature;
- and
- a bone cement injector configured to inject a mixture of the liquid monomer component and the non-liquid polymer component into the patient.
A method of providing a bone cement for injection into a patient, the method comprising:
- determining a bone cement delivery start time based on a pre-mix temperature determined using a temperature sensor affixed to a bone cement kit package, the bone cement kit package comprising a first package containing a liquid monomer component and a second package containing a non-liquid polymer component comprising at least two polymer bead populations having different average sizes and different weight percentages.
