Prospective, Multicenter, Multidisciplinary, Controlled Clinical Investigation Evaluating the Safety and Efficacy of PerClot® Polysaccharide Hemostatic System

This is a prospective, multicenter, multidisciplinary, controlled clinical investigation evaluating the safety and efficacy of PerClot in achieving intraoperative hemostasis compared to a similar marketed hemostatic device. Three hundred and twenty four subjects across a maximum of 25 investigational sites undergoing open elective cardiac, general, or urological surgical procedures who meet the eligibility criteria will be intraoperatively randomized to receive no more than the entire contents of up to two 5 gram bellows of either the investigational device or a control hemostatic agent on a bleeding site, whose anatomic site is smaller than or equal to 25cm² and whose anatomic application site is smaller than or equal to 47cm², when bleeding is within the pre-defined bleeding severity range after any applicable conventional means for hemostasis are attempted as specified in the intraoperative procedures. Each investigational site is expected to enroll approximately 13-40 subjects. All investigational sites will be located in the U.S. Follow-up will occur at hospital discharge and 6 weeks post-device application. For oncologic subjects, an additional follow up will occur at 24 months post device application.
