## Abstract

The invention relates to a mesh support device (10) for supporting a breast implant (20), wherein the mesh support device (10) has a tubular shape. The invention relates further to a breast implant device for implantation in a human body, comprising a breast implant (20) and a mesh support device (10), in which the breast implant (20) is positioned, wherein the mesh support device (10) has a tubular shape. In accordance with the invention, a method for preparing a breast implant (20) for implantation in a human body is also disclosed.

## Claims

### Claim 1

A breast implant device for implantation in a human body, comprising:
a breast implant (20); and
a mesh support device (10), in which the breast implant (20) is positioned,
wherein the mesh support device (10) is elongated so as to extend from a first end to a second end,
wherein the mesh support device (10) has an opening at the first end through which the breast implant (20) has been inserted, and
wherein the breast implant (20) has a rounded frontside and an essentially flat backside and the mesh support device (10) comprises:
a front portion that covers the frontside of the breast implant,
a back portion that covers the backside of the breast implant, and
a folded portion that is folded backwards along the back portion so as to lie essentially parallel with the backside of the breast implant (20) and contact a back surface of the back portion.

### Claim 2 (depends on 1)

The breast implant device according to claim 1, wherein the breast implant (20) at least partly is made from silicone and/or saline.

### Claim 3 (depends on 1)

The breast implant device according to claim 1, wherein the breast implant has a diameter D2 and a perimeter P2 and the mesh support device has length L1 and a perimeter P1, wherein P1≥P2 and L1≥D2+100 mm.

### Claim 4 (depends on 3)

The breast implant device according to claim 3, wherein P1≥P2+X mm, where X is in an interval of 5 mm to 60 mm.

### Claim 5 (depends on 3)

The breast implant device according to claim 3, wherein P1≥P2+X mm, where X is in an interval of 20 mm to 45 mm.

### Claim 6 (depends on 1)

The breast implant device according to claim 1, wherein the mesh support device (10) is made from a bio-degradable material.

### Claim 7

A method for preparing a breast implant (20) for implantation in a human body, comprising the steps of:
providing a breast implant (20) having a rounded frontside and an essentially flat backside;
determining the diameter D2 of the breast implant (20);
providing a mesh support device (10) having a tubular shape with a length L1 and a diameter D1, wherein L1≥D2+100 mm, and wherein a perimeter P1 of the mesh support device (10) is greater than or equal to a perimeter P2 of the breast implant (20);
positioning the breast implant (20) in the mesh support device (10) such that such that a portion of the mesh support device (10) extends a distance L2 beyond a rim of the breast implant (10); and
folding said portion backwards such that:
a front portion of the mesh support device (10) covers the frontside of the breast implant,
a back portion of the mesh support device (10) covers the backside of the breast implant, and
the folded portion is folded backwards along the back portion so as to lie essentially parallel with the backside of the breast implant (20) and contact a back surface of the back portion.

### Claim 8 (depends on 7)

Method according to claim 7, wherein L2 is more than 50 mm and P1≥P2+X mm, where X is in an interval 5 mm to 60 mm.

### Claim 9 (depends on 7)

Method according to claim 7, wherein L2 is more than 50 mm and P1≥P2+X mm, where X is in an interval of 20 mm to 45 mm.
