Embodiment 1

[0052] Such as Figure 1 to Figure 9 Shown is a blood pulse wave regulating device provided by this embodiment, which is covered on the outside of the blood vessel wall 12 when implanted into the human body, and includes: a supporting body 1 and a link assembly.

[0053] Such as figure 1 As shown, the inner cavity of the tubular support body 1 is cylindrical, the hardness of the support body is not less than the hardness of the blood vessel wall at the covered place, and the inner diameter of the support body 1 is smaller than the outer diameter of the blood vessel at the place covered by it. The main body 1 is placed outside the blood vessel wall 12 , and at least one dividing slit is provided on the side wall of the supporting main body 1 along the axial direction of the supporting main body 1 . In this embodiment, the support body 1 is provided with a separation seam, through which the support body 1 can be unfolded into a sheet shape, and after the support body 1 is sent ...

Embodiment 2

[0067] Such as Figure 10 to Figure 12 Shown is a blood pulse wave regulating device provided by this embodiment, which is supported on the inner side of a blood vessel wall 12 when implanted into a human body, and includes: a supporting body 1 and an anchoring component 11 .

[0068] The supporting body 1 is a cylindrical tubular structure, and the outer diameter of the supporting body 1 is larger than the inner diameter of the blood vessel covered by it. The anchor assembly 11 is fixedly connected to the supporting body 1 . The anchor assembly 11 includes a bracket 13 and a plurality of anchor barbs 14 arranged on the bracket 13 , the bracket 13 is fixedly connected with the support body 1 , and the plurality of anchor barbs 14 are arranged at intervals along the circumference of the support body 1 . After the anchoring barb 14 is implanted in the blood vessel, the anchoring barb 14 is obliquely inserted into the inner wall of the blood vessel, and the inclination direction...

Abstract

The invention relates to the technical field of medical instruments, in particular to a blood pulse wave adjusting device which is used for wrapping the outer side of a blood vessel wall. The device comprises a tubular supporting main body, wherein at least one dividing seam is formed in the side wall of the supporting main body in the axis direction of the supporting main body; and a linking assembly which comprises a first connecting piece and a second connecting piece which are detachably matched with each other, wherein the first connecting piece and the second connecting piece are arranged on the supporting main body on the two sides of the dividing seam respectively. The invention further relates to another blood pulse wave adjusting device which is used for being supported on the inner side of the blood vessel wall and comprises a tubular supporting main body; and an anchoring assembly which is fixedly connected to the supporting body. The blood pulse wave adjusting device is implanted into a human body, the inner diameter or hardness of a local blood vessel is changed through the supporting body, then the taper of the inner wall of the local blood vessel is changed, or the compliance of the local blood vessel is changed, and therefore, the intensity and phase of abnormal pulse waves are adjusted; the condition that blood pressure in a lesion blood vessel area is too high or blood supply of far-end organs is insufficient is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a blood pulse wave regulating device. Background technique [0002] The pulse wave of the human body includes forward wave and reflected wave, and the superposition of the two forms the final pulse wave waveform. Common pulse waves include pressure wave and flow wave. Abnormal pulse wave waveform is closely related to a series of clinical symptoms, and the common cause of abnormal pulse wave is vascular sclerosis, that is, diffuse vascular atherosclerosis. Many elderly people have varying degrees of arteriosclerosis. In addition to age factors, obesity, smoking, alcoholism, endocrine disorders, stress, mental stimulation, poor diet and living habits, and insufficient exercise are all related to arteriosclerosis. Arteries are elastic, and the inner walls of blood vessels are very soft, which can buffer part of the blood pressure, make the blood flow smoothly, and the ...
