HEMOBLAST Pilot Clinical Investigation

Phase 1

Completed

• Conditions: Hemostasis
• Interventions: Device: HEMOBLAST Bellows

• Registration Number: NCT02502019
• Lead Sponsor: Biom'Up France SAS

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.
