Embodiment Construction

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the following examples are given in conjunction with the accompanying drawings to further describe the present invention in detail. It should be understood that the following specific examples are only used to illustrate the general principles and preferred implementation modes of the present invention, and should not be used to limit the technical solution of the present invention.

[0034] The embodiment of the present invention provides a heart defect occluder, which is used to occlude the abnormal opening of the heart, and is especially suitable for a more complicated type of heart defect anatomical structure (such as PFO). The following uses the PFO occluder as an example to illustrate .

[0035] The side of a heart defect occluder in the prior art is as figure 1 As shown, it mainly includes an elastic double disc structure, and the an...

Abstract

The invention provides a heart defect amplatzer for repairing heart defects. The heart defect amplatzer comprises a left disk and a latticed right disk, the left disk comprises at least two support rods, the support rods pass through lattices of the right disk to connect the right disk and the left disk, each support rod is woven or wound from a plurality of fine wires and also can comprise a spring and a central ring-shaped part. Since such a combined structure is applied to the heart defect amplatzer, the flexibility, stability and fatigue durability of the left disk can be obviously improved, the harmful effects of the amplatzer on hart tissues are reduced; therefore the adaptability and the safety of the amplatzer are improved. The heart defect amplatzer is more suitable for a complicated heart defect anatomical structure.

Description

technical field [0001] The invention relates to a medical device, in particular to an occluder for treating heart diseases, which can be used to repair patent foramen ovale (PFO), atrial septal defect (ASD), ventricular septal defect (VSD), ductus arteriosus patent (PDA), etc. Background technique [0002] Common structural defects of the human heart include atrial septal defect (ASD), ventricular septal defect (VSD), patent ductus arteriosus (PDA), patent foramen ovale (PFO), etc. The PFO and ASD are located between the left and right atria of the heart, and such gaps in the interatrial septum may cause blood to flow directly from the right atrium to the left atrium. The size of the PFO is generally smaller than that of the ASD, and it is generally not perpendicular to the interatrial septum. The center of the entrance of the PFO in the right atrium and the center of the exit of the PFO in the left atrium are staggered, that is, "non-concentric". Placing the occluder in t...
