Regulatory science promotes the translation of transcatheter tricuspid valve repair/replacement devices.

For patients with symptomatic and severe tricuspid regurgitation but inoperable with open surgery, transcatheter tricuspid valve intervention (TTVI) is a procedure of great clinical value. TTVI products include repair and replacement devices. TTVI products are one of the hotspots of investigation now, with different innovative biomaterials and structural designs in trials to satisfy divergent indications and reduce complications.

[Bacterial Endotoxin for Intrathoracic Medical Devices Requirement Revisited].

Bacterial endotoxin is considered as one of the critical risk factors in medical devices, especially implanted devices that directly or indirectly contact with blood circulating system. In that case, endotoxin limits for implanted medical devices is important in determine the safety of medical devices. According to GB/T 14233.
