Method For Preparing A Haemostatic Composition

Patent No. EP3790600 (titled "Method For Preparing A Haemostatic Composition") was filed by Ethicon on May 9, 2019. The application was issued on Dec 27, 2023.

Patent Summary

A method for preparing a haemostatic composition involves reconstituting a dry thrombin composition directly into a biocompatible polymer paste in a single-step operation. The process comprises providing the dry thrombin in a first syringe and a paste—comprising a biocompatible polymer selected from gelatine, collagen, chitin, chitosan, alginate, cellulose, oxidised cellulose, polyglycolic acid, or polyacetic acid—in a second syringe. The syringes are connected via suitable means (e.g., a static mixer) and their contents are mixed. This method eliminates the need for separate thrombin reconstitution prior to mixing, ensuring a substantially homogenous distribution of thrombin and faster induction of haemostasis compared to conventional multi-step preparations. The resulting flowable, putty-like paste is used for treating wounds and controlling bleeding.
