A significant part of the adult female population with the age are affected by at least one troublesome pelvic floor disorder such as pelvic organ prolapse, stres urinary urinary incontinence, pelvic pain, vaginal tissue athrophy, and sexual dysfunction. The female pelvic structures have varying viscoelastic characteristics across physiological states, healthy and diseased conditions.
The Vaginal Tactile Imager (VTI) obtains a high resolution mapping of pressures and assesses the strength of pelvic floor muscles within the vagina. The real time data as well the analysis information can then be viewed with an intention of assisting in the diagnosis and evaluation of vaginal and pelvic floor conditions. The VTI provides a large body of measurements to evaluate individual variations in support defects as well as identify specific potential markers to measure tissue properties and muscle function. The device is intended for use by physicians, surgeons and medically trained personnel.
The further progress in women's healthcare is possible if a patient with a problematic pelvic floor conditions could undergo opportunely imaging and biomechanical diagnostic tests; the results of which could be fed into a structured patient-specific diagnostic workflow to consider multiple treatment options and to suggest the optimal one for that patient.
Currently there are no efficient, standardized, non-invasive techniques for assessing of pelvic floor disorders and monitoring its treatment. VTI fills this gap providing a possibility to detect and quantitatively characterize the changes in physiological and anatomical manifestations of female pelvic floor transformation. The commercialization partner of Artann, a startup company Advanced Tactile Imaging. Inc., applies efforts to bring VTI to worldwide market.
