← Product Code MTJ · K141502 # HBP4 HARDENING, RESORBABLE HEMOSTATIC BONE PUTTY (K141502) _Orthocon, Inc. · MTJ · Oct 3, 2014 · SU · SESE_ **Canonical URL:** https://fda.innolitics.com/device/K141502 ## Device Facts - **Applicant:** Orthocon, Inc. - **Product Code:** MTJ - **Decision Date:** Oct 3, 2014 - **Decision:** SESE - **Submission Type:** Traditional - **Device Class:** Class U - **Review Panel:** SU - **Attributes:** Therapeutic ## Intended Use HBP4 Hardening, Resorbable Hemostatic Bone Putty is indicated for the control of bleeding from cut or damaged bone by acting as a mechanical barrier or tamponade. ## Device Story HBP4 is a sterile, resorbable, putty-like hemostatic material for bone surfaces. It consists of two components—granular calcium phosphate, calcium stearate, vitamin E acetate, triglyceride, polyalcohol, and lactide-diester/polyester-based polymers—that are manually mixed immediately prior to use. The mixture forms a hardening, radiopaque putty applied directly to bleeding bone by a surgeon. It functions via mechanical tamponade, occluding vascular openings in damaged bone. The material is resorbable, with components degrading via dissolution and hydrolysis. It is intended for single-use in surgical settings to achieve local hemostasis, providing a benefit by stopping bleeding from bone while being resorbed over time, unlike traditional non-resorbable bone waxes. ## Clinical Evidence No human clinical data provided. Evidence consists of bench testing (stiffness, spreadability, stickiness, temperature sensitivity, electrocautery compatibility, dissolution, swelling), biocompatibility testing (ISO 10993: irritation, sensitization, toxicity, genotoxicity, implantation, hemolysis, pyrogenicity), and animal studies (in vivo hemostasis, resistance to irrigation, resorption time). ## Technological Characteristics Two-part putty system; components: calcium phosphate, calcium stearate, vitamin E acetate, triglyceride, polyalcohol, lactide-diester/polyester-based polymers. Radiopaque. Resorbable. Manual mixing required. Sterilized via gamma irradiation. Single-use. Mechanical tamponade principle. ## Predicate Devices - Skeletal Kinetics CAAP (Calcium Apatite) Bone Wax ([K111538](/device/K111538.md)) - US Surgical Auto Suture Bone Wax ([K971680](/device/K971680.md)) - CP Medical Bone Wax ([K024372](/device/K024372.md)) - Ceremed Ostene® CT Bone Hemostasis Implant ([K102071](/device/K102071.md)) - Orthocon Hemostatic Bone Putty 3 ([K123243](/device/K123243.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

This testing included the following: Bench Testing was conducted to verify the device's handling properties, to characterize the device's performance over a range of temperatures and to evaluate the device's dissolution properties. The following bench studies were completed: relative stiffness, spreadability, stickiness, temperature sensitivity, electrocautery compatibility, dissolution and swelling. Biocompatibility Testing was conducted to evaluate the device's biocompatibility in accordance with the recommendations of ISO 10993. The following biocompatibility studies were conducted on the final, finished, gamma-irradiated sterile device in accordance with the GLP requirements: irritation, sensitization, acute systemic toxicity, genotoxicity, implantation, subacute systemic toxicity, chronic systemic toxicity, hemolysis, endotoxicity and pyrogenicity. Animal Testing included animal studies to demonstrate intraoperative in vivo hemostasis, resistance to irrigation, and to characterize resorption time. ## Conclusion HBP4 is substantially equivalent to previously cleared bone wax devices with respect to intended use, general technological characteristics and performance. --- **Source:** [https://fda.innolitics.com/device/K141502](https://fda.innolitics.com/device/K141502) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
