Clinical Study Evaluating the Performance of HEMOBLAST Bellows Compared to FLOSEAL Hemostatic Matrix in Cardiothoracic Operations

A maximum of 104 subjects will be enrolled across a maximum of 5 study sites in the United States.

Enrollment occurs intraoperatively after confirmation of the intraoperative eligibility criteria. Subjects will undergo intraoperative performance assessments and then will be discontinued from the study after completion of the intraoperative visit.
