<p>A carrier device for an artificial internal organ has a matrix of porous nickel titanium alloy, the porosity of the matrix being effective to isolate cells of the desired internal organ in the matrix, from immune system entities, for example macrophages. The matrix is, in particular, derived from a powder composition composed of 45 to 55 %, by weight, of nickel powder and 55 to 45 %, by weight, titanium powder, to a total of 100 %; and titanium nickel alloy powder in an amount of 5 to 30 %, by weight, based on the total weight of nickel and titanium powders.</p> |
