Embodiment 1

[0034] An implantable medical device comprising:

[0035] Ontology 1;

[0036] A protective film 2, covering the surface of the body 1, for reducing the degradation rate of the body 1;

[0037] The surface of the body 1 has a certain roughness, and the protective film 2 is directly coated on the surface of the body 1 . In the present invention, the surface of the main body 1 is treated to make it have a certain roughness, so that the protective film 2 can be better attached to the main body 1, so that the protective film 2 is not easy to fall off.

[0038] The main body 1 is made of magnesium or magnesium alloy material, and the main body 1 has a crown and bridge ribs, and the protective film 2 covers the crown and bridge ribs. Since the crown and the tendons are the key protection positions, covering them with the protective film 2 can slow down the degradation rate of the weak positions.

[0039] The thickness of the protective film 2 is 10nm-1000nm.

[0040] The protect...

Embodiment 2

[0043] A method for manufacturing a medical device implantable inside a living body, comprising the following steps:

[0044] Step 1, preparing the body 1;

[0045] Step 2, performing surface treatment so that the surface of the body 1 has a certain roughness;

[0046] Step 3, coating the protective protective film 2.

[0047] In the present invention, the surface of the main body 1 is treated to make it have a certain roughness, so that the protective film 2 can be better attached to the main body 1, so that the protective film 2 is not easy to fall off.

[0048] The body 1 is prepared by laser cutting or wire welding.

[0049] The surface treatment is surface sandblasting, the number of mesh of the abrasive used is 200 mesh, the sandblasting power is 200w, the distance between the nozzle and the surface of the body 1 is 1mm, the moving speed of the body 1 is 2mm / s, and the rotation speed is 2mm / s. 0.5 turns / s.

[0050] The surface treatment is plasma treatment with a pow...

Abstract

The invention discloses a medical device implanted in vivo and a manufacturing method of the medical device. The medical device comprises a body and a protective film which covers the surface of the body and is used for reducing the degradation speed of the body, the surface of the body has a certain roughness and is directly coated with the protective film. By surface treatment, the surface of the stent body has a certain roughness, so that the protective film is closely connected with the body and does not easily fall off.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an implantable medical device and a manufacturing method thereof. Background technique [0002] Implantation of intravascular medical devices has become a treatment for intravascular stenosis or thrombosis, such as stent implantation (PCI), which is a routine treatment for coronary atherosclerosis. Since the world's first bare metal stent was launched in the market in 1997, PCI Surgery has become the dominant method for the treatment of coronary atherosclerosis, and coronary intervention is generally recognized by the majority of doctors and patients. [0003] In order to prevent intravascular restenosis caused by excessive proliferation of endothelial cells after stent implantation, bioabsorbable stents have emerged as the times require. It is easy to corrode, and its corrosion products have no toxic effect on organisms, and participate in the normal metabolism of the human body....
