Patent ID: 8617237

Claim:
A tubular supporting prosthesis comprising: two terminal regions relative to the longitudinal axis of the supporting prosthesis and a middle region disposed between the two terminal regions, wherein each of said terminal regions comprises a mesh structure made of at least two structural rings which are connected to one another via connecting members and are disposed point symmetrically about the longitudinal axis of the supporting prosthesis, wherein the middle region is formed by elongated connecting members which are connected with each of the structural rings disposed closest to the middle point of the longitudinal axis of the supporting prosthesis, wherein an aortic valve produced by means of tissue engineering is fixed and/or integrated into the middle region, and wherein at least one of the structural ring and connecting members comprise at least one predetermined breaking point which comprises multiple layers of different biologically degradable materials, wherein the multiple layers of different biologically degradable materials are located only at the predetermined breaking point area, such that the rate of dissolution of the predetermined breaking point proceeds in a chronologically graduated manner.
