## Abstract

The present disclosure is directed to a medical implant (20) comprising: —a coil-shaped component (21) and —a first mesh component (22) and a second mesh component (23); wherein each mesh component has a largest surface extending in two directions in the x-y plane of the mesh component, and wherein each mesh component has a projected area, which is said largest surface as projected in the x-y plane of the medical implant; wherein the coil-shaped component is arranged between the two mesh components; wherein the coil-shaped component has a center core which is hollow; and wherein the coil-shaped component has a helix rotation axis, which extends in parallel with said projected area of the first mesh component and said projected area of the second mesh component.

## Claims

### Claim 1

A medical implant comprising:
a degradable coil-shaped component and
a first degradable mesh component and a second degradable mesh component;
wherein each mesh component has a largest surface extending in two directions in the x-y plane of the mesh component, and
wherein each mesh component has a projected area, which is said largest surface as projected in the x-y plane of the medical implant;
wherein
the coil-shaped component is arranged between the two mesh components;
the coil-shaped component has a center core which is hollow; and
the coil-shaped component has a helix rotation axis, which extends in parallel with said projected area of the first mesh component and said projected area of the second mesh component,
wherein the coil-shaped component comprises a fiber component, which has been helically wound to form the coil-shaped component,
wherein the coil-shaped component has a helical pitch which is larger than the width of the fiber component which forms the coil-shaped component, wherein said width is measured in the direction of the helix rotation axis,
wherein said helical pitch of the coil-shaped component is in a range of from 1 to 15 mm.

### Claim 2 (depends on 1)

The medical implant according to claim 1, wherein a cross-sectional profile of the coil-shaped component has a hollow center core area, which is larger than a cross-sectional area of the fiber component which forms the coil-shaped component.

### Claim 3 (depends on 1)

The medical implant according to claim 1, wherein a cross-sectional profile of the coil-shaped component is axially constant or variable in size, and/or is axially constant or variable in shape.

### Claim 4 (depends on 1)

The medical implant according to claim 1, wherein the coil-shaped component is formed as a circle, an oval, a rectangle, an S-form, a straight line, a U-turn, or any other irregular form, between said two mesh components, in a plane parallel to said projected areas of the mesh components.

### Claim 5 (depends on 1)

The medical implant according to claim 1, wherein the coil-shaped component is contained between said two mesh components.

### Claim 6 (depends on 1)

The medical implant according to claim 1, wherein said two mesh components are attached to each other at edges of the mesh components.

### Claim 7 (depends on 1)

### Claim 8 (depends on 1)

The medical implant according to claim 1, wherein said two mesh components are attached to the coil-shaped component by threading a loop of the coil-shaped component through each mesh component.

### Claim 9 (depends on 1)

The medical implant according to claim 1, wherein the number of mesh components is in a range of from 2 to 10, and wherein at least one coil-shaped component is arranged between each two mesh components.

### Claim 10 (depends on 1)

The medical implant according to claim 1, wherein a number of coil-shaped components arranged between each two mesh components is in a range of from 1 to 100.

### Claim 11 (depends on 10)

The medical implant according to claim 10, wherein coil-shaped components arranged between the same two mesh components are intertwined, overlapping, braided, axially aligned, axially perpendicular, axially at an angle of between 0° and 90°, and/or are separated from each other.

### Claim 12 (depends on 6)

The medical implant according to claim 6, wherein said two mesh components are attached to each other at edges of the mesh components by suturing, stapling, or gluing.

### Claim 13 (depends on 7)

The medical implant according to claim 7, wherein said two mesh components are attached to a part of the envelope surface of the coil-shaped component by stitching or suturing.

### Claim 14

A medical implant comprising:
a degradable coil-shaped component and
a first degradable mesh component and a second degradable mesh component;
wherein each mesh component has a largest surface extending in two directions in the x-y plane of the mesh component, and
wherein each mesh component has a projected area, which is said largest surface as projected in the x-y plane of the medical implant;
wherein
