Definitions
- Oxide layers do not necessarily impair the body tolerance of implants, but they do provide a surface that is expected to be low in hemocompatibility and so the use of vitamin K antagonists and other anticoagulants, such as in the treatment of patients who receive such an implant Acetylsalicylic acid. This places an additional burden on the patient concerned.
- the present invention is therefore based on the object of providing a device based on Nitinol which is suitable as an artificial implant and which is to be distinguished by a high degree of body tolerance and very good hemocompatibility.
- a device should be able to withstand the considerable temperature fluctuations and mechanical stresses, such as, for example, elastic expansions of up to approximately 8%, which occur during the processing and application of the material Nitinol, without a deterioration in the property profile of the device, such as e.g. Detachment or cracking, survive. This should be achieved in particular without the use of a plasticizer, otherwise the physical tolerance of such an implant would be significantly reduced.
- a device comprising a substrate based on essentially nitinol and arranged thereon at least partially a coating or a coating based on at least one polymer with the following general formula (I),
- the heterocycloalkyl radical is, for example, a ring system containing 3 to 7 atoms, at least one ring atom being a nitrogen atom.
- the heterocycloalkyl radical can be substituted, for example, with at least one alkyl radical defined above.
- Examples of heterocycloalkyl radicals are piperidinyl, piperazinyl, pyrrolidinyl and morpholinyl groups and derivatives thereof.
- the heteroaryl radical is, for example, a compound with one or more aromatic Ring systems, wherein at least one ring atom is a nitrogen atom.
- the heteroaryl radical can be substituted, for example, with at least one alkyl radical defined above. Examples of heteroaryl radicals are pyrrolyl, pyridinyl, pyridinolyl, isoquinolinyl and quinolinyl groups, and derivatives thereof.
- the polymer is poly [bis (trifluoroethoxy) phosphazene].
- the polymer can also be a poly [bis (trifluoro-ethoxy) phosphazene] labeled with 32 P, 33 P or As or Sb isotopes.
- the nitinol substrate which is coated thereon and has a coating of the polyphosphazene polymer of the formula (I), is in the form of an at least partially perforated tube, as is the case, for example, with an endovascular implant, such as a stent , is common.
- the coating of at least one polyphosphazene polymer of the formula (I) arranged or deposited on the nitinol substrate according to the present invention can furthermore contain one or more pharmaceutically active compounds, such as cell-toxic compounds such as rapamycin, taxol, doxorubicin, platinum derivatives, 5-fluoroacyl or anti-inflammatory agents such as diciofenac or acetylsalicylic acid or other agents in appropriate galenical preparation, preferably with a delayed release or quantitatively controlled release over a longer period.
- pharmaceutically active compounds such as cell-toxic compounds such as rapamycin, taxol, doxorubicin, platinum derivatives, 5-fluoroacyl or anti-inflammatory agents such as diciofenac or acetylsalicylic acid or other agents in appropriate galenical preparation, preferably with a delayed release or quantitatively controlled release over a longer period.
- the adhesion promoter in particular improves the adhesion of the coating to the surface of the nitinol substrate by coupling the adhesion promoter to the nitinol surface, for example via ionic and / or covalent bonds, and further coupling to the described polymer of the formula (I) of the coating, for example via ionic and / or covalent bonds.
- Another object of the present invention relates to the manufacture of the device according to the invention, comprising the steps:
- the nitinol-based substrate can be provided in step (a), for example in the form of an at least partially perforated tube.
- the substrate essentially comprises nitinol as the structure that builds up the substrate. end material.
- the nitinol-based substrate may already have been subjected to electropolishing or other treatment to produce a dense surface which is impermeable to nickel ions.
- the structuring of the polymer coating is not subject to any specific definition. Structures in the order of magnitude of nanometers, micrometers or even larger or smaller, preferably in the range from 10 nm to 100 ⁇ m, can be produced. Furthermore, all structures can be produced and used which can be produced photolithographically or with electron beams, X-rays or laser beams or by means of other techniques.
