no. 2 example

[0083] Such as Figure 8 , 9 As shown, the ventricular separation device 100a provided by the second embodiment of the present invention is substantially the same as the ventricular separation device 100 in the first embodiment, and includes a partition part 1a and a fixing part 2a. The fixing part 2a and the partition part 1a are separately provided and connected to each other. The fixing part 2a has a connecting piece 23a, a second connecting head 22a, and a fixing piece 21a disposed between the connecting piece 23a and the second connecting head 22a.

[0084] The only difference is that in this embodiment, the fixing member 21a of the partition 1a is not a single disc structure, but two interconnected double disc structures. Specifically, the fixing member 21a includes a first disc 211a, a second disc 212a and a waist 213a. The waist portion 213a is disposed between the first disc 211a and the second disc 212a, and the first disc 211a is disposed close to the partition 1...

no. 3 example

[0089] Such as Figure 11 As shown, the ventricular separation device 100b provided by the third embodiment of the present invention is substantially the same as the ventricular separation device 100 in the first embodiment, and includes a partition part 1b and a fixing part 2b. The partition part 1b includes a partition body 11b, and a bluff body 12b disposed on the partition body 11b.

[0090] The only difference is that in this embodiment, the partition part 1b and the fixing part 2b are not provided separately, but integrally formed. The partition part 1b and the fixing part 2b are integrally formed, that is, the partition body 11b of the partition part 1b and the fixing part 2b are integrally formed. The separator 11b and the fixing portion 2b are mesh bodies formed by weaving braided wires having a shape-memory function. Specifically, there is a connection part 10b between the fixing part 2b and the partition 11b, and the connection part 10b is formed by a plurality of...

[0092] Such as Figure 12 As shown, the ventricle separation device 100c provided by the fourth embodiment of the present invention is substantially the same as the ventricle partition device 100a of the second embodiment, and it includes a fixing part 2c and a partition part 1c. The partition part 1c includes a partition body 11c and a bluff body 12c disposed on the partition body 11c.

Abstract

The invention provides a ventricle separating device and a making method thereof. The ventricle separating device comprises a fixing part and a separating part, wherein the fixing part is mutually connected with the separating part; the separating part comprises a first cambered surface and a second cambered surface, wherein the first cambered surface is installed on a side, close to the fixing part, of the second cambered surface, and the edges of the first cambered surface and the second cambered surface are connected in a butt joint mode; the first cambered surface and the second cambered surface are both recessed toward the side where the fixing portion is located, and the radius of curvature of the first cambered surface is less than that of the second cambered surface. By means of the ventricle separating device and the making method thereof, the blood is prevented from leaking from a contact position between the ventricle separating device and a ventricular wall, and the separation of ventricular lesion location is good.

Description

technical field [0001] The present invention relates to a medical device and its manufacturing method, more specifically to an interventional treatment device which can be used to separate ventricles and its manufacturing method. Background technique [0002] Congestive heart failure, characterized by progressive enlargement of the heart, especially the left ventricle, is currently the leading cause of death and disability. As a patient's heart enlarges, the heart pumps blood less efficiently, and in time, the heart becomes so enlarged that it cannot adequately supply the body with blood. Patients with congestive heart failure often have an ejection fraction of 40% or less, and the result is chronic fatigue, physical disability and burdened with pain and discomfort. Also, as the heart enlarges, the heart valves lose their ability to close adequately. An incompetent mitral valve allows the backflow of blood from the left ventricle back into the left atrium, further reducing...
