Identification of Predicate Device(s) The identified predicates within this submission are as follows: The Hemospray® Endoscopic Hemospray®) has been cleared by FDA through De Novo No. DEN170015 (Date: May 7, 2018). The EndoClot® Applicator has been cleared by FDA through 510(k) No. K162197 (Date: January 18, 2017). {4}------------------------------------------------ # K190677 Page 2 of 3 ### 5. Description of the Device EndoClot® Polysaccharide Hemostatic System (EndoClot® PHS) is a sterilized single use medical device that is composed of Absorbable Modified Polymer (AMP®) particles in a PE bellow and an EndoClot® Applicator (K162197). The device contains no human or animal components. AMP® particles are biocompatible, non-pyrogenic and derived from plant starch. ### 6. Intended Use/Indication for Use EndoClot® PHS is used for hemostasis of nonvariceal gastrointestinal bleeding, excluding Forrest la classification of bleeding. ### 7. Technological Characteristics EndoClot® PHS is composed of Absorbable Modified Polymer (AMP®) particles in a PE bellow and an EndoClot® Applicator (K162197). AMP® particles are delivered through a catheter inserted through the working channel of an endoscope which provides access to the bleeding site. When compared with Hemospray® (DEN170015), EndoClot® PHS has the same intended use but with reduced indications for use. They are with the same classification and same application technique that the particles are delivered by gas source and through a catheter inserted through the working channel of an endoscope which provides access to the bleeding site. Yet, there are also multiple dimensions are different, which are hemostatic particles and packaging. However, these different parts have been verified to be substantial equivalent. When compared with EndoClot® Applicator (K162197), the applicator of EndoClot® PHS is identical with EndoClot® Applicator (K162197). ### 8. Performance Data Performance tests, biocompatibility tests, chemical characterization, sterility test and in vivo animal studies were conducted to demonstrate that Endoclot® PHS and the predicate devices are substantially equivalent. According to the performance tests, the properties (Pressure of Gas Source, Spray Pattern, Delay Time and Powder Feeding Rate, Water Absorbency and pH) of EndoClot® PHS are similar to or better than the predicate device Hemospray®. The results demonstrated that the proposed device is substantially equivalent to the predicate device for these performance measures. The biocompatibility tests (Cytotoxicity, Sensitization, Intracutaneous Reactivity, Acute Systemic Toxicity, Pyrogen, Systemic Toxicity, Genotoxicity, Hemocompatibility and Endotoxins), chemical characterization and sterility test in accordance to Food and Drug Administration related guidance and recognized international standards (ISO10993-5:2009, ISO10993-10:2010, ISO10993-11:2017, ISO10993-18:2020, OECD 471:1997, OECD 473:2016, {5}------------------------------------------------ OECD 474:2016, ASTM F756-17, USP42_NF37<85> and ISO11737-2:2009/(R)2014), indicated that Endoclot® PHS is substantially equivalent to the predicate. In vivo animal studies have also been conducted to support the substantial equivalence claims of our product as compared to the predicate device Hemospray®. The objective of the study was to validate the efficacy and safety of EndoClot® PHS (compared to the predicate device) in a swine model for gastrointestinal bleeding control. The results demonstrated that the proposed device is substantially equivalent to the predicate. ## 9. Conclusion [21 CFR 807.92(b) (3)] EndoClot® PHS has a reduced scope of intended use, with the same classification and application technique compared with Hemospray® (DEN170015). The applicator of EndoClot® PHS is identical with EndoClot® Applicator (K162197). A series of tests were conducted to verify the safety and efficacy of Endoclot® PHS: 1) The performance tests demonstrated that the proposed device meets the design specifications and is suitable for the intended use. 2) The biocompatibility tests, chemical characterization and sterility test indicated that the proposed device is substantially equivalent to the predicate. 3) The in vivo animal studies demonstrated that the proposed device is substantially equivalent to the predicate. In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807 and based on the information provided in this premarket notification, EndoClot Plus Co., Ltd. concludes that EndoClot® PHS is substantially equivalent to predicate devices.
