DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0023] In FIGS. 1a, b and c an embodiment of a medical support device 1 of the present invention is shown. The medical support device 1 comprises at least a wall shaped portion 2. It has a first side 3, which shows a bulge out of a plane 4 and a second side 5 that has a corresponding cavity. For example, the wall shaped portion 2 may have a dome shape, although it is possible to have any particular shape according to the purpose of the supporting in the human body.

[0024] The wall shaped portion 2 is curved over at least two different thought axes or draped, i.e. it does not have shape of a partial cylinder. Preferably it has a thickness between the first side 3 and the second side 5 which is more or less the same over the bulge/cavity. In FIG. 1b the medical support device 1 is shown in a plan view from the first side 2. In the shown embodiment the device has a more or less circular footprint, although any shape would be possible. In FIG. 1c the embodiment of FIGS. 1a and b is shown from the side.

[0025] The medical support device 1 is for supporting endogenous tissue and/or fat in place in a human body part. Any suitable body part may receive the medical support device 1, such as in the buttocks or breasts, although it would probably be mostly used in women's breasts. The medical device 1 will support endogenous tissue or fat or both against gravitational pull. It is also conceivable to add other materials suitable to be in a human body, such as hyaluronic acid. Or only use other material or materials in the cavity portion of the medical support device 1.

[0026] The medical support device 1 comprises either an elastomer or matrix, or both. The elastomer material may be of any kind suitable to be used with a human body and being pliable. The elastomer may for example be a silicon rubber, preferably of the type used in breast implants. The matrix may be built up by biological or synthetic materials or a combination thereof. It could comprise absorbable and/or non-absorbable material. For example, it could be an acellular dermal matrix.

[0027] In FIG. 2a an embodiment of a medical support device 1 is shown in cross section where at least a portion of a rim 6 is provided at an edge 7 of the cavity or bulge in the plane 4. The at least one portion of the rim 6 may be more easily attached to tissue in a human body than attaching only an edge 7. Preferably, any suture may be used for this, absorbable or not.

[0028] In FIG. 2b an embodiment is shown in a plan view where several portions of the rim 6 is provided and in FIG. 2c a full rim 6 surrounding the edge 7 is shown. In FIG. 2d another embodiment is shown where the wall shaped portion 2 is cut off 8 in its upper portion and having a rim 6 around the edge 7 left in the plane 4 so that a pocket is formed when attached to tissue in the human body. All the shown embodiment in FIG. 2 may comprise an elastomer and/or matrix.

[0029] Different embodiments of how a combination of an elastomer and matrix will now be exemplified in FIGS. 3a-g. In FIG. 3a a dome-shaped medical support device 1 is shown made of elastomer and having a portion of matrix 9 provided on the second side 5 in the lower region. Obviously, matrix 9 may be provided all over the second side 5 or, as shown in FIG. 3b, all over the first side 3, or over a portion of the first side 3. In FIG. 3c a medical support device 1 having a rim 6 is shown where matrix 9 is provided at the rim 6 on the same side as the second side 5 of the wall shaped portion 2. It is also conceivable to have matrix 9 on the other side, as is shown in FIG. 3f or on both sides. In FIG. 3d matrix 9 is provided both in the cavity, the second side 5, and at the rim 6. In FIGS. 3e and 3g matrix 9 is provided on a lower portion of the cavity and bulge, respectively, as well as along the rim 6.

[0030] Obviously, the shape of the medical support device 1 may differ according to its use and purpose. In FIG. 4a a more or less dome-shape is shown, preferably a partial sphere, and in FIG. 4b an anatomical shape is shown. The projection may differ, too, as well as the height of a projection point 12. The footprint of the medical support device 1 may also differ according to its use and purpose. In FIGS. 5a and 5b two different examples are shown, circular having the same height as width; or having different height compared to the width, respectively. The height may be longer than the width or vice versa. For example, the footprint may be oval or as shown in FIG. 5b, drop shaped.

[0031] Now examples of how a medical support device 1 may be produced will be described. In FIGS. 6a, b and c three different mandrels are shown. The mandrel is dipped in an elastomer in a flowing condition. Then it is taken up and the elastomer hardens into a pliable condition. This could be effectuated by means of heat or added substances, for example. The dipping usually is repeated a desired number of times. The elastomer is taken off the mandrel, and if needed cut to desired shape. It is possible to turn it inside out, i.e. the surface of the elastomer closest to the mandrel will instead become the bulge side, the first side 3.

[0032] In case a special surface is desired, such as a textured surface, it is possible to provide it on the first side 3 or second side 5, respectively, or on both sides. Different roughness from fine to coarse may be provided by having a surface structure on the mandrel. It is also possible to imprint a texture on the outermost layer, before hardening. For example, it is possible to use polyurethane or a salt to imprint.

[0033] If a rim 6 is desired a mandrel according to FIGS. 6b and 6c may be used. If a combination of elastomer and matrix is desired parts of matrix may be arranged at the mandrel at desired positions, or over the full mandrel surface, before the dipping. Alternatively, the matrix is arranged after the dipping before hardening.

[0034] The medical support device 1 may be provided in a range of sizes making it possible to find a suitable size for the special needs of each patient.

[0035] In FIG. 7 a use of the medical support device 1 is shown. The medical support device 1 is positioned inside a human body part 10, in this case a female breast. In the present case the deep gland tissue and/or fat is separated and a portion of it is provided inside of the cavity, i.e. on the second side 5 of the medical support device 1. The medical support device is attached with sutures 11. The sutures are preferably of the absorbable type. The medical support device may for example be attached in a muscle, the breast muscle in the shown case. It is also conceivable to provide fat or other tissue, preferably endogenous, within the cavity of the medical support device in addition to gland tissue or only fat or only other tissue. It is also conceivable to add hyaluronic acid or other medical injectable material in the cavity, alone or mixed with endogenous tissue of any or several kinds.

[0036] In FIG. 8 it is shown the possibility to add, for example hyaluronic acid or fat, by means of a syringe into a cavity of a medical support device already in place in a human body part 10. This puncturing will not do any harm as no harmful material may leak out as it would with a common breast implant filled with silicone gel.
