Abstract

The invention provides a covered stent. The covered stent comprises a covered stent body and a medicine storage device. The covered stent body is internally provided with a circulation space with two communicated ends; the medicine storage device is fixed to the covered stent body, at least part of the medicine storage device is located on the outer side of the covered stent body, a medicine storage space is formed in the medicine storage device, a medicine feeding hole is formed in the medicine storage device, and the medicine storage space is communicated with the external environment through the medicine feeding hole. Compared with the prior art, the covered stent provided by the invention has the advantages that antibacterial and anti-infection medicines can be stored in the medicine storage device, and the medicines can be released outwards through the administration holes, so that the covered stent has better anti-infection capability.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a covered stent. Background technique [0002] Covered stent refers to a stent coated with special membrane materials (polytetrafluoroethylene, polyester, polyester, polyurethane, etc.) on the metal stent, which not only retains the function of the metal stent, but also has Properties of membrane materials. Covered stents are generally nickel-titanium alloy stents with a layer of polymer material film attached to form a self-expanding artificial pipeline fixed in the human blood vessel cavity for the treatment of aneurysms, arterial dissection, blood vessel rupture and bleeding and other diseases. [0003] Thoracic aortic endovascular repair (TEVAR) and abdominal aortic endovascular repair (EVAR) are minimally invasive procedures in the vascular cavity. Compared with traditional surgical methods, TEVAR and EVAR have obvious advantages such as less trauma, shorter recove...
