Definitions
- This invention relates to a biomedical aid or implant.
- This invention relates in particular to biomedical aids such as stents, aneurysm clips, cardiac valves, occlusion coils, suture materials, artificial joints and osteosynthesis materials.
- a stent must satisfy a number of requirements. Important, first of all, are the mechanical properties. A stent is typically built up from thin wires or from a tube in which holes are provided, whilst the forces a stent is subject to in, for instance, an artery, can be considerable. Therefore it is important that the stent can resist sufficient pressure, but also that the stent is sufficiently elastic.
- the relative weight ratio between gold and palladium will preferably be between 3:1 and 0.5:1, more preferably between 1.6:1 and 1:1.
- the relative weight ratio between silver and palladium will preferably be between 3: 1 and 0.3:1, more preferably between 1.3: 1 and 0.4:1.
- the alloy preferably contains a number of dopes.
- the total amount of dopes is preferably between 0.5 and 40% by weight, more preferably between 4 and 40% by weight, depending on the amount of precious metal present. It is preferred that the alloy contains only metals, so that the total amount of dopes is preferably adjusted to the amount of precious metals present. Accordingly, in certain cases, the upper limit of the amount of dopes can be 25% by weight.
- the dopes are preferably selected from the group of iridium, indium, gallium, tin, titanium, copper, zinc, and ruthenium.
- the dopes mentioned can be used both separately and in mutual combinations. It has been found that these dopes have a particularly favorable influence on the properties, in particular the mechanical properties, of the alloy.
- the dopes referred to are preferably present in the following amounts:
- a metal can be present, selected from the group of rhodium, rhenium, cerium, germanium, boron, iron, tantalum, nickel, cobalt, aluminum, niobium, zirconium, manganese, chromium, molybdenum and tungsten.
- These metals too can be used both separately and in combinations. In particular when they are used in the amounts specified hereinafter, these dopes too can have a favorable effect on the alloy properties relevant to the invention. Nonetheless, the effect of these dopes will generally be somewhat less than that of the above-discussed dopes.
- the preferred amounts of this second group of dopes are: Rhodium up to 30% by weight, preferably up to 10% by weight, more preferably from 0.1 to 1% by weight;
- Rhenium up to 5% by weight, more preferably from 0.1 to 1% by weight;
- Cerium up to 5% by weight, more preferably from 0.1 to 1% by weight;
- Germanium up to 5% by weight, more preferably from 0.1 to 3% by weight; Boron up to 3% by weight, more preferably from 0.1 to 0.5% by weight;
- Iron up to 5% by weight, more preferably from 0.1 to 3% by weight;
- Nickel up to 30% by weight, more preferably from 1 to 10% by weight, still more preferably entirely absent; Cobalt up to 30% by weight, more preferably from 1 to 10% by weight;
- Aluminum up to 3% by weight, more preferably from 0.1 to 1% by weight; Niobium up to 15% by weight, more preferably from 1 to 5% by weight; Zirconium up to 5% by weight, more preferably from 0.1 to 2% by weight; Manganese up to 5% by weight, more preferably from 0.1 to 2% by weight; Chromium, molybdenum and tungsten jointly up to 5% by weight, more preferably from 0.1 to 1% by weight.
- the alloy for manufacturing a stent must have a yield point of at least 200 N/mm 2 and an elongation at break of at least 8%.
- the yield point is at least 300 N/mm 2 and the elongation at break is at least 20%. It has been found that through a suitable choice of the composition of the alloy, a yield point can be achieved of more than 400 N/mm 2 with an elongation at break of about 30%.
- the yield point is defined as measured according to ISO 6892 on an alloy which has been hard-annealed.
- the elongation at break is defined, according to the invention, as measured according to the same ISO 6892 on an alloy which has been soft-annealed.
- the conditions under which hard-annealing or soft-annealing occurred, are the optimum conditions for respectively hard- and soft-annealing the composition of the alloy. The artisan will be capable of choosing these on the basis of his ordinary skill in the art.
- a bar manufactured of the alloy to be measured is loaded incrementally on a tensile strength tester until break.
- the forces exerted on the bar are graphically represented and the elongation at break is determined by measuring the length of the parallel part of the bar before and after the test. More particularly, the following quantities can be calculated from the results of this test, in the following manner: max
- a applied (expressed in Newton) and A is the surface area of the cross section of the parallel part of the bar prior to break (expressed in mm 2 );
- Lo parallel part of the bar after the test, and Lo is that same length before the test.
- the artisan will be able to choose the composition of the alloy, in particular the nature and amount of the dopes present therein, such that the above-mentioned requirements regarding the mechanical properties are met.
- the known preparation referred to comprises the steps of preparing a melt comprising the desired metals in the desired amounts, casting the melt to form an ingot, homogenizing by tempering, cooling and hardening.
- Tempering can be carried out at a temperature between 650 and 1200°C.
- tempering is done at a temperature of about 900°C.
- Cooling is preferably carried out by cooling the tempered alloy in water.
- cooling is done fast (immediately after tempering).
- the cooled alloy is subsequently rolled out to a smaller thickness or drawn into a wire.
- Rolling preferably occurs in different steps, alternated by a tempering at a temperature of 650-1200°C, preferably about 900°C.
- the eventual hardening of the alloy preferably occurs at a temperature of 400-700°C, more preferably at a temperature of 500-650°C.
- a stent can be formed in a conventional manner.
- the alloy can be used for manufacturing all known kinds of stents.
- stents for arterial applications such as in the abdominal, pelvic, femoral, cervical, renal and coronary arteries
- stents for venous applications including applications in the venae cavae and application in TIPS (Transjugular Intrahepatic Portosystemic Shunt)
- stents of the balloon-expandable or self- expandable type the group formed by covered stents, stent-grafts, and endografts (i.e.
- stents combined with vascular prosthetic material for treating aneurysmal and stenosing vascular disease including application in abdominal aortic aneurysm), and stents for non-vascular applications, such as hepatobiliary, gastrointestinal, urological and bronchial applications.
- vascular prosthetic material for treating aneurysmal and stenosing vascular disease including application in abdominal aortic aneurysm
- non-vascular applications such as hepatobiliary, gastrointestinal, urological and bronchial applications.
- the alloy of which the present stent is manufactured is suitable for manufacturing other biomedical aids or implants.
- the term 'biomedical aids or implants' is understood to include all objects foreign to the body, which are permanently or temporarily deployed in the body. Often, these objects serve to support or replace body functions which have failed wholly or partly, and/or to assist in restoring certain body functions or parts of the body.
- the aids/implants involved here are particularly those where in a comparable manner the mechanical properties and MRI properties play a role, and which are utilized in the human body at a site where they are not exposed to the atmosphere, which is in effect understood to include all applications not belonging to dentistry.
