Gore in Japan has announced the first clinical use of the Gore Excluder thoracoabdominal branch endoprosthesis (TAMBE) in the East Asian country. The device, which enables endovascular treatment of thoracoabdominal aortic (TAAAs) and pararenal aneurysms while preserving blood flow to visceral branches, is approved both in the USA and Japan, noted the company.
The first TAMBE procedure in Japan was performed in October 2025 by Takao Ohki (Jikei University School of Medicine, Tokyo, Japan) supported by Jason T. Lee (Stanford Medicine, Stanford, USA).
“There had been no approved minimally invasive treatment option in Japan for aneurysms involving visceral branches such as thoracoabdominal and pararenal aneurysms,” said Ohki in a Gore press release. “Many patients at high risk for surgery have remained untreated or treated with suboptimal procedures, including debranching TEVAR/EVAR or physician-modified TEVAR/EVAR. TAMBE offers a potential option for patients who previously had limited treatment options.”
