Summary

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.

For cardiac procedures, the site of evaluation for satisfaction of intraoperative eligibility criteria will be any bleeding sites on the epicardium, along an aortic anastomotic suture line, or an aortotomy suture line. For example, the surgeon will perform dissection of adhesions per his or her conventional methods and bleeding will be controlled using means continually employed by the surgeon prior to surgical closure. Prior to application along an aortic anastomotic suture line or an aortotomy suture line, suture line gaps > 2mm and large needle holes > 2mm will be ligated prior to assessment of intraoperative eligibility criteria. Any bleeding site on the epicardium, or along an aortic anastomotic suture line, or an aortotomy suture line meeting the eligibility criteria will be evaluated for satisfaction. PerClot should be applied after drug reversal and the patient is taken off by-pass.
perclot polysaccharide hemostatic system
During the intraoperative period, the subject will be evaluated for bleeding; only those who meet the intraoperative inclusion criterion will be enrolled into the study. After confirmation of the intraoperative eligibility criteria, the subject will be randomized to receive an adjunct application of PerClot or the control device. The prescribed hemostatic agent will be applied according to its Instructions for Use.

During the intraoperative period, the subject will be evaluated for bleeding; only those who meet the intraoperative inclusion criterion will be enrolled into the study. After confirmation of the intraoperative eligibility criteria, the subject will be randomized to receive an adjunct application of PerClot or the control device. The prescribed hemostatic agent will be applied according to its Instructions for Use.
(Experimental)
For liver resection procedures, the resected liver surface will be the site of evaluation. The surgeon will perform resection of the diseased portion of the liver per his/her conventional methods. Bleeding from discrete vessels will be controlled using means conventionally employed by the surgeon. Vessels > 2mm in diameter will be ligated and any observed bile leaks controlled prior to assessment of intraoperative eligibility criteria. For total splenectomy procedures, the site of evaluation for satisfaction of the intraoperative eligibility criteria will be the retroperitoneal surface. The surgeon will perform the splenectomy per his/her conventional methods. Vessels > 2mm in diameter will be ligated prior to assessment of intraoperative eligibility criteria. Any bleeding site on the retroperitoneal surface/cavity or exposed parenchymal surface will be evaluated for satisfaction of the eligibility criteria.

(Experimental)
For on-clamp partial nephrectomies, the site of evaluation will be the kidney bed surface. The surgeon will perform resection of the kidney per his or her conventional methods. Vessels > 2mm in diameter will be ligated and entries into the collecting system controlled prior to assessment of intraoperative eligibility criteria. Any bleeding site on the kidney bed will be evaluated for satisfaction of the eligibility criteria after clamp release. For radical nephrectomies, the site of evaluation will be the retroperitoneal surface/cavity. The surgeon will perform the procedure per his or her conventional methods. Vessels > 2mm in diameter will be ligated prior to assessment of intraoperative eligibility criteria. Any bleeding site on the retroperitoneal surface/cavity will be evaluated for satisfaction of the eligibility criteria.

Eligibility Criteria

Male or female participants at least 22 years old.

Inclusion Criteria: - Preoperative inclusion: - Subject is undergoing one of the following open elective cardiac, general, or urological surgical procedures: Cardiac procedure (Epicardium); Cardiac procedure (aortic anastomosis or aortotomy suture line); Liver resection; Total splenectomy; On-clamp partial nephrectomy; or Radical nephrectomy. - Subject is willing and able to give prior written informed consent for investigation participation; and - Subject is > 22 years of age. - Intraoperative inclusion: - Subject is undergoing one of the following elective procedures: Cardiac procedure (Epicardium); Cardiac procedure (Aortic Anastomosis or Aortotomy suture line); Liver resection; Total splenectomy; On-clamp partial nephrectomy; or Radical nephrectomy. - Subject in whom all visible vessels or suture holes greater than or equal to 2mm in diameter have been ligated; - Subject in whom there is bleeding at the specified area for each surgical procedure after any applicable conventional means for hemostasis are attempted as specified by the intraoperative protocol; - Subject in whom the anatomic site is equal to or less than 25cm²; - Subject in whom the anatomic application site is equal to or less than 47cm²; and - Subject in whom the bleeding flux from the identified lesion is > 0.000040[g/(cm²•s)] and ≤0.013[g/(cm²•s)].
