Abstract
A medical implant includes a first implant body and a pre-coating covering at least a portion of an outer surface of the first implant body. The pre-coating has a negative Poisson's ratio. A method of making a medical implant includes applying a precursor material on a surface of a first implant body, the first implant body having a positive Poisson's ratio. A stimulus is applied to the precursor material, the stimulus causing the precursor material to form a coating having a negative Poisson's ratio
Claims17
A medical implant comprising:
- a first implant body comprising:
- a first portion having a positive Poisson's ratio, and
- an internal second portion embedded in the first portion, the internal second portion having a negative Poisson's ratio;
- and
- a pre-coating covering at least a portion of an outer surface of the first implant body, the pre-coating having a negative Poisson's ratio.
