Abstract

A soft tissue implant such as a breast implant, calf muscle prosthesis and the like, comprises an external shell-type envelope (1) of flexible plastic material, in particular of silicone; a liquid to viscous filler material (5) contained in the envelope (1); and a metal-containing, biocompatible, continuous coating (9) on the outside (7) of the envelope (1).

Claims

1. A soft tissue implant, such as a breast implant, calf-muscle prosthesis and the like, comprising;

an external, shell-type envelope (1) of flexible plastic material, in particular silicone;

a liquid to viscous filler material (5) contained in the envelope (1); and

a metal-containing, biocompatible, continuous coating (9) on the outside (7) of the envelope (1);

wherein a metal-containing continuous coating (10) is additionally applied to the inside (8) of the envelope (1).

2. A soft tissue implant according to claim 1, wherein the coating (9, 10) is a titanium-containing coating of a thickness of less than 2 μ

m, preferably of 5 to 700 nm.

3. A soft tissue implant according to claim 2, wherein the coating (9, 10) comprises a compound of the formula

Ti_aO_bC_c,

with a=0.025 to 0.9,

b=0.025 to 0.7 and

c=0.2 to 0.9

applying.

4. A soft tissue implant according to claim 1, wherein the outside (7) of the envelope (1) is smooth.

5. A soft tissue implant according to claim 1, wherein the outside (7) of the envelope (1) has a rough surface.

6. A soft tissue implant according to claim 1, wherein the filler material (5) is a viscous silicone gel.

7. A soft tissue implant according to claim 1, wherein the filler material (5) is a physiological sodium chloride solution or water.
