Document Type and Number:
WIPO Patent Application WO/2012/012270
Kind Code:
A4
Abstract:
Bone material delivery devices and methods of using the devices are provided. The bone material delivery devices and methods comprise thermochromic material disposed on the exterior of the syringe, the thermochromic material configured to provide an indication of temperature, viscosity, and/or age of bone replacement material in the interior of the syringe. In some embodiments, a time indicating label is disposed on the exterior of the syringe, the time indicating label comprising a label substrate having a first surface comprising an acid-base indicator and a second surface comprising an activator, wherein when the first surface is brought into contact with the second surface or when the second surface is brought into contact with the first surface, at least a portion of the label changes color indicating elapsed time. In some embodiments, the devices and methods allow the practitioner to know the dough time, working time, and setting time of the bone replacement material when it is in the syringe.
