Claim 9:
10. The instrument according to claim 8, wherein said processing unit (60) is configured to:
calculate a plurality of values of an energy amount received by said instrument upon said contact (C) between said gas-inflatable balloon (20) and said wall (90) at different values of a couple of deformation parameters (x,R) of said gas-inflatable balloon (20), said energy comprising an energy portion associated to a deformation of said gas-inflatable balloon (20) and an energy portion associated to a compression of said gas within said gas-inflatable balloon (20), due to said contact (C);
calculate a relationship between said deformation parameters (x,R) based on an equation of state of said gas, so as to obtain said values of said energy amount as a relationship with only one deformation parameter (x,A) of said deformation parameters;
calculate said contact force (F) as a product between said contact pressure (P) as a relative pressure and contact surface area (A) of said gas-inflatable balloon (20) and said wall.
