Optimized Implant System
In order to improve local specificity and adjustability of the radiant power in radiation diagnostics and in post-operative radiation therapy, the invention devises an implant system ( 100, 100′, 100″, 100 ′″) having a structural part ( 50, 50′, 50″, 50 ′″) that can be implanted in a damaged tissue region ( 30 ) and has at least a first region ( 10 a, 10 b, 10 c, 10 d ) made of a first material and at least a second region ( 20 a, 20 b, 20 c, 20 d ) made of a second material, the first region ( 10 a, 10 b, 10 c, 10 d ) being designed to support the structural part ( 50, 50′, 50″, 50 ′″) and being substantially impermeable to a predetermined radiation for the purpose of diagnostics or for medical radiation therapy, and the second region ( 20 a, 20 b, 20 c, 20 d ) being designed to complement the first region ( 10 a, 10 b, 10 c, 10 d ) to the structural part ( 50, 50′, 50″, 50 ′″) and further comprising at least one portion ( 22 a, 2 b, 22 c, 22 d ) that is structurally modified. The portion ( 22 a, 2 b, 22 c, 22 d ) of the second region ( 20 a, 20 b, 20 c, 20 d ) is permeable to the predetermined radiation for the purpose of diagnostics or for medical radiation therapy.
1 . An implant system comprising:
a structural part which is implantable into a damaged tissue area and which has at least one first region formed from a first material and at least one second region formed from a second material, wherein
the first region is arranged to support the structural part and is substantially impenetrable for a specified radiation for diagnostics or for medical radiation therapy;
the second region is arranged to supplement the first region to form the structural part and is provided with at least one section having a structural modification, and
the section of the second region is penetrable for the specified radiation for diagnostics or for medical radiation therapy.
2 . The implant system as claimed in claim 1 , wherein the second material is different from the first material.
3 . The implant system as claimed in claim 1 , wherein the second region is in the form of an insert in the first region.
4 . The implant system as claimed in claim 1 , wherein the second region is in the form of a cut-out in the first region.
5 . The implant system as claimed in claim 1 , wherein the at least structurally modified section has a lower material density than its surrounding area.
6 . The implant system as claimed in claim 1 , wherein the second region has a regular or irregular perforated grid structure.
7 . The implant system as claimed in claim 1 , wherein the first material is a mechanically stable material, in particular a metallic material.
8 . The implant system as claimed in claim 7 , wherein the metallic material is formed from titanium, titanium alloys, molybdenum, molybdenum alloys, magnesium, magnesium alloys, implantable stainless steel or a combination of at least two of these materials.
9 . The implant system as claimed in claim 1 , wherein the second material is in the form of a plastics material, ceramic material, composite or a resorbable combination of these.
10 . The implant system as claimed in claim 9 , wherein the plastics material is formed from at least one polymer such as PEEK (polyetheretherketone), PEKK (polyetherketoneketone), PE (polyethylene), PPSU (polyphenylsulfone) or a combination of at least two of these materials.
11 . The implant system as claimed in claim 9 , wherein the ceramic material is formed from aluminum oxide or zirconium oxide.
12 . The implant system as claimed in claim 9 , wherein the resorbable component is composed of HA (hydroxyapatite), β-TCP (beta-tricalcium phosphate), combinations of HA/β-TCP, β-TCP/Mg, PDLLA/Mg (poly-d,l-lactic acid), PDLLA/β-TCP, PDLLA/CaCC or similar materials.
13 . The implant system as claimed in claim 1 , wherein the radioactive radiation is particle radiation, in particular electron radiation, or wave radiation, in particular X-radiation.
14 . The implant system as claimed in claim 1 , wherein the structural part is designed to replace a damaged bone area in the region of the cranium or mandible.
