Conditions
Brief summary
The primary objective of this pilot clinical investigation is to assess the reliability of the Surface Bleeding Severity Scale (SBSS) in a clinical setting. Secondary objectives of this clinical investigation are to collect initial data on the safety and efficacy of HEMOBLAST™ Bellows in abdominal and orthopedic lower extremity surgeries.
Detailed description
HEMOBLAST™ Bellows is intended for use in surgical procedures as an adjunct to hemostasis when control of bleeding by conventional procedures is ineffective or impractical. This is a prospective, multicenter, single-arm pilot clinical investigation. There will be 36 subjects enrolled across 4 investigational sites. The subjects will be followed at hospital charge and 6 weeks postoperatively. The primary endpoint of this clinical investigation is the mean paired Kappa statistic for the assignment of SBSS scores by 2 Investigators. Secondary endpoints of this clinical investigation consist of: * Proportion of subjects achieving hemostasis within 6 minutes of HEMOBLAST™ Bellows application; * Proportion of subjects achieving hemostasis within 10 minutes of HEMOBLAST™ Bellows application; * Proportion of subjects achieving hemostasis within 3 minutes of HEMOBLAST™ Bellows application; and * Incidence of adverse events through final follow-up.

Eligibility
Inclusion criteria
* • Subject is undergoing an elective open abdominal or orthopedic lower extremity surgery; * Subject or an authorized legal representative is willing and able to give prior written informed consent for investigation participation; * Subjects on antiplatelets, including aspirin, will discontinue medication at least 10 days prior to surgery; and * Subject is 21 years of age or older. * Subject does not have an active or suspected infection at the surgical site; * Subject in whom the Investigator is able to identify a target bleeding site (TBS) for which any applicable conventional means for achieving hemostasis are ineffective or impractical; and * Subject has a TBS with an SBSS score of 1, 2, or 3.
Exclusion criteria
* • Subject is undergoing a laparoscopic, thoracoscopic, or robotic surgical procedure; * Subject is undergoing a spinal surgical procedure; * Subject is undergoing a neurologic surgical procedure; * Subject is undergoing an emergency surgical procedure; * Subject is pregnant, planning on becoming pregnant during the follow-up period, or actively breast-feeding; * Subject has a clinically significant coagulation disorder or disease, defined as a platelet count \< 100,000 per microliter and/or International Normalized Ratio \> 1.5 within 4 weeks of surgery; * Subject had chronic corticosteroid use within 2 weeks prior to surgery; * Subject receiving intravenous heparin or oral Coumadin within 24 hours of surgery; * Subject has an active or suspected infection at the surgical site; * Subject has had or has planned any organ transplantation; * Subject has a known sensitivity or allergy to bovine and/or porcine substance(s) or any other component(s) of the hemostatic agent; * Subject has ASA classification of \> 4; * Subject has a life expectancy of less than 3 months; * Subject has a known psychiatric disorder, which in the opinion of the Principal Investigator, would preclude the subject from completing this clinical study; * Subject has a documented severe congenital or acquired immunodeficiency; * Subject has religious or other objections to porcine or bovine components; * Subject in whom the investigational device will be used at the site of a cemented or uncemented porous coated joint implant; * Subject is currently participating or has participated in another clinical trial within the past 30 days and is receiving/has received an investigational drug, device, or biologic agent; and * Subject is not appropriate for inclusion in the clinical trial, per the medical opinion of the Principal Investigator.
