Torsional waves


Innitius’ medical devices develop a novel technology called Torsional Waves, a type of shear elastic waves that propagate through soft tissue, radially and in-depth in a curled geometry.

Torsional Waves are used to diagnose pathologies that manifest themselves through changes in tissue consistency.

Our first product, FineBirth’s patented intravaginal probe measures the consistency (shear modulus) of the cervical tissue, a highly specific, direct marker of pending birth.

The shear modulus, in combination with other clinical parameters of the pregnant woman, is used by an Artificial Intelligence algorithm to provide a real-time assessment of whether the woman is experiencing a true or false preterm labor threat and informs health professionals in providing appropriate care.
