Implantable medical device and implantable medical device kit

Abstract

The invention provides an implantable medical device and an implantable medical device suite, the implantable medical device comprises a main body lumen structure, the main body lumen structure comprises a main body stent and a covering film, the covering film covers the main body stent to form a delivery channel with two open ends, and the delivery channel is communicated with the main body stent. At least one opening capable of being opened and closed is formed in the covering film, the opening divides the main body pipe cavity structure into a near-end part and a far-end part, and when the near-end part or the far-end part is compressed in the radial direction and the far-end part or the near-end part is not compressed in the radial direction, the opening is in an open state; when the main body pipe cavity structure is in a radial unfolding state, the opening is in a closed state; and in the opening state, the opening is communicated with the conveying channel. The implantable medical device can keep the blood flow smooth in the operation process, and can avoid or reduce internal leakage after the operation is completed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an implantable medical device and an implantable medical device kit. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] Aortic dissection, also known as aortic dissection aneurysm, refers to the hematoma formed when blood in the aortic lumen enters the middle layer of the aortic wall through a breach in the intima. Aortic dissection is a high-risk arterial disease with High mortality and morbidity rates. [0004] The traditional method of treating aortic dissection is generally surgical treatment, usually removing the intima tear, preventing massive bleeding caused by dissection rupture, and reconstructing the blood flow channel through artificial blood vessels. [0005] At present, a covered stent is implanted in the diseased part by means of minimally invasive int...

Problems solved by technology

[0007] However, in the process of releasing the branch stent, because the main stent is located in the blood vessel, it is in a half-released state and not fully opened, which will block the blood flow to a certain extent

When the blood flow is blocked for too long, it will have adverse effects on the patient's health, and even life-threatening
