What this Trial Is About
Researchers are observing the use of the ClotTriever4 Thrombectomy System in treating patients with deep vein thrombosis who have acute severe symptoms. The study aims to assess the safety and effectiveness of this device during everyday clinical practice after it was approved for marketing in Japan. This survey is important as it evaluates real-world results following regulatory approval. Participants will receive treatment using the ClotTriever4 Thrombectomy System, which is designed to remove blood clots from veins. The survey includes all patients in Japan who have the device inserted into their blood vessels as part of their treatment. There are no separate treatment groups; everyone treated with the device is included. During the study, researchers will monitor participants for any major adverse events up to 30 days after the procedure. They will also assess whether the device successfully completes the clot removal during the procedure itself. The survey will continue until December 2028 and collects data from all treated patients to understand the device's performance in general clinical use.
