简要总结
The purpose of this clinical investigation in open, elective, spine surgery is to collect data to support the removal of the neurosurgical exclusion from the currently approved indication for the use of HEMOBLAST™ Bellows. This study is primarily designed to assess safety of the device for use in spine surgery, although efficacy information will also be captured and reported.
