Abstract

A material that is less populated by biofilms than known materials and is well tolerated by the body is provided. The material is an element introducible into or attachable on a human or animal body and includes a glass and/or glass ceramic and/or ceramic material at least in some areas thereof, which inhibits the formation of biofilms and/or on which human or animal cells grow if the element is introduced into the human or animal body or attached thereto, wherein the glass and/or glass ceramic material comprises at least: SiO 2 in a range from 60 to 75 wt % and ZnO in a range from 1 to 7 wt %.

First claim

What is claimed is:

1. An element introducible into or attachable on a human or animal body, comprising an electronic component casing including at least a portion thereof of a material selected from the group consisting of glass, glass ceramic, ceramic, and any combinations thereof, wherein the material inhibits the formation of biofilms, and wherein the material comprises at least: SiO 2 in a range from 60 to 75 wt % and ZnO in a range from 1 to 7 wt %.

2. The element as claimed in claim 1 , wherein the material comprises:
SiO 2 in a range from 60 to 75 wt %,
R 2 O in a range from 5 to 20 wt %,
RO in a range from 0 to 10 wt %,
Al 2 O 3 in a range from 1 to 6 wt %,
B 2 O 3 in a range from 0 to 10 wt %,
TiO 2 in a range from 0 to 8 wt %,
ZnO in a range from 1 to 7 wt %, and
FeO 0 to 5 wt %,
wherein R 2 O is an oxide or a combination of oxides selected from the group consisting of Li 2 O, Na 2 O, and K 2 O, and
wherein RO is an oxide or a combination of oxides selected from the group consisting of MgO, CaO, BaO, SrO, and any combinations thereof.

3. The element as claimed in claim 1 , wherein the material comprises:
SiO 2 in a range from 60 to 70 wt %,
R 2 O in a range from 5 to 20 wt %,
RO in a range from 0 to 10 wt %,
Al 2 O 3 in a range from 1 to 5 wt %,
B 2 O 3 in a range from 0 to 10 wt %,
TiO 2 in a range from 0 to 8 wt %,
ZnO in a range from 1 to 7 wt %,
FeO in a range from 0 to 5 wt %, and
Na 2 O in a range from 2 to 10 wt % and/or
K 2 O in a range from 3.5 to 10 wt %;
wherein R 2 O is an oxide or a combination of oxides selected from the group consisting of Li 2 O, Na 2 O, and K 2 O, and
wherein RO is an oxide or a combination of oxides selected from the group consisting of MgO, CaO, BaO, SrO, and any combinations thereof.

4. The element as claimed in claim 1 , wherein the material comprises:
a content of Ag of less than 0.3 wt %; and/or
a content of P 2 O 5 of less than 0.5 wt %; and/or
a content of F of less than 1 wt %.

5. The element as claimed in claim 1 , wherein the casing is in the form of a tube.

6. The element as claimed in claim 1 , wherein the material configured for use as an insulating component of a feedthrough of the casing, wherein the casing is of stainless steel or titanium and/or a titanium alloy.

7. The element as claimed in claim 1 , further comprising a component selected from the group consisting of an implant, a vascular support, a stent, a catheter, a transponder casing, a defibrillator, a pacemaker, a lab-on-chip, a contact lenses, and a contact lens coating.

8. The element as claimed in claim 1 , wherein the material comprises
SiO 2 in a range from 62 to 66 wt %
Al 2 O 3 in a range from 3.8 to 4.5 wt %
B 2 O 3 in a range from 0 to 10 wt %
TiO 2 in a range from 3.5 to 4.5 wt %
ZnO in a range from 5 to 7 wt %
FeO in a range from 0.001 to 0.005 wt %
Na 2 O in a range from 5.9 to 6.5 wt %, and
K 2 O in a range from 8.3 to 9.1 wt %, where
SeO 2 in a range from 0 to 0.04 wt %.
