The invention concerns an endovascular implant comprising a biodegradable material and having a tubular main body which is open at the ends and which is dilatable from an unexpanded condition into an expanded condition. The implant is so designed that when the implant in the expanded condition is subjected to a radially acting compression pressure in the range of between 5 and 30 kPa (0.05-0.3 bar)

Implant of low radial strength

An implant for releasing an active substance into a vessel through which a body medium flows. The implant release an active substance into a vessel through which a body medium flows downstream from the location of the implant. A base of a biodegradable material is a carrier of the active substance to be released. The body medium flows past the implant and the active substance is release. The implant is configured so that the active substance does not contact a vessel wall at the location of implant.

Implant for releasing an active substance into a vessel through which a body medium flows

A radio-opaque marker for medical implants comprising between 10 and 90 weight percent of a biodegradable base component, between 10 and 90 weight percent of one or more radio-opaque elements selected from the consisting of I, Au, Ta, Y, Nb, Mo, Ru, Rh, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Hf, Ta, W, Re, Os, Ir and Bi as a marker component and 10 weight percent of residual components, the aforementioned components amounting to 100 weight percent.

Radio-opaque marker for medical implants

The invention relates to a medical implant made of a metallic material. After fulfilling its temporary support function, the implant is degraded by corrosion at a predetermined rate. Negative long-term effects are thus avoided.

Metallic implant which is degradable in vivo

An endoprosthesis includes a carrier structure which contains a metallic material. The metallic material contains a magnesium alloy of the following composition: magnesium: &#x3e;90%, yttrium: 3.7%-5.5%, rare earths: 1.5%-4.4% and balance: &#x3c;1%.
