1. A method for measuring a mechanical property of a vascular wall which deforms in response to a transmural force under usual physiologic pressures, the method comprising:

  • altering an initial transmural force to obtain at least one altered transmural force wherein the step of altering includes the step of reducing the transmural force to obtain a reduced transmural force and wherein the step of reducing includes the step of applying an external pressure to the vascular wall;

    measuring local changes in position of at least one location within the vascular wall resulting from physiologic pressures with the at least one altered transmural forces during the step of altering; and

    determining a value for the mechanical property based on a measured amount of the local changes.
