摘要:
A magnesium alloy having Y, Zn, Ca, Mn, Ag, Ce, Zr, or Si. The alloy is distinguished in that, in the event of suitable treatment, the alloy is convertible into a very fine-grained microstructure, in particular, having grain sizes less than 20 μm. The alloy components are not or are hardly toxicologically relevant.

An implant having a base body comprising entirely or in part a biocorrodible iron alloy wherein the base body of the implant comprises at least one of the following: (i) a biocorrodible iron alloy of formula (1): Fe—P where the amount of P in the alloy is from 0.01 to 5 wt %, and Fe plus impurities due to the production process account for the remainder of the alloy up to 100 wt %; or (ii) a biocorrodible iron alloy of the formula (2): Fe—Mn—X where the amount of Mn in the alloy is from 5 to 30 wt %, X stands for one or more elements selected from the group consisting of Pt, Pd, Ir, Rh, Re, Ru and Os, and the amount of X in the alloy is from 0 to 20 wt % and Fe plus impurities due to the production process account for the remainder of the alloy up to 100 wt %; or (iii) a biocorrodible iron alloy of formula (3): Fe-Z where Z is one or more elements selected from the group consisting of Pt, Ir and Os and the amount of Z in the alloy is from 5 to 30 wt %, and Fe plus impurities due to the production process account for the remainder of the alloy up to 100 wt %.
摘要:
A magnesium alloy, comprising: Y:0.5-10 Zn:0.5-6 Ca:0.05-1 Mn: 0-0.5 Ag:0-1 Ce:0-1 Zr:0-1 or Si: 0-0.4, wherein the amounts are based on weight-percent of the alloy and Mg, and manufacturing-related impurities constitute the remainder of the alloy to a total of 100 weight-percent. Also disclosed is a method for manufacturing such an alloy and a biodegradable implant formed therefrom.
摘要:
An implant comprising an implant material forming a base made of one or more metallic elements; a diffusion layer covering the base made of at least one of the metallic elements of the implant material and at least magnesium; and, optionally, a metal layer covering the diffusion layer made of magnesium or a biocorrodible magnesium alloy.

摘要:
A medical implant comprising a composite material which is composed of reinforcement fibers made of a magnesium-containing, bio-corrosive alloy, another bio-corrosive alloy containing a main component that is selected from the group consisting of Mg, Ca, Fe, and Y, or a non-biodegradable fiber material, embedded in a matrix made of crystalline magnesium or magnesium alloys.

摘要:
An application head for dispensing a flowable medium includes a nozzle chamber in the application head and a nozzle needle movably mounted in the nozzle chamber. A supply channel and a supply line introduce the medium into the nozzle chamber. A drive moves the movable element. A lever arm is movably fastened to the nozzle needle and connected to the drive. The lever arm extends through a membrane of a membrane suspension connect the lever arm movably to the application head and form a seal to prevent escape of the flowable medium. Alternatively, a rocker suspension has a lever arm connectable to the movable element and the drive, a plate element has an opening through which the lever arm extends, a rocker mounting device connects the lever arm movably to the application head and a sealing device prevents any escape of adhesive from the chamber through the plate element opening.
