The injectable hemostatic agent XStat consists of an applicator syringe filled with small compressed foam sponges that expand when they come into contact with blood.  

It offers another option for controlling external hemorrhage and is best suited for deep narrow tract and junctional wounds that are otherwise difficult to compress with external pressure. 

This device is not indicated for use in the thorax, pleural cavity, mediastinum, abdomen, retroperitoneal space, sacral space, above the inguinal ligament, and tissues above the clavicle.

Do not attempt to remove sponges in the field.
