  • Publication number: 20130144191
    Abstract: Transvaginal probes equipped with tactile sensors are configured for placement into vagina to record tactile response during insertion, acquire static tactile pattern from vaginal wall after the insertion is complete, and acquire dynamic tactile patterns during probe motion as well as recording dynamic tactile response during contraction of vaginal muscle. The acquired and recorded tactile data are transmitted to a data processor for composing tactile profile of vagina and visually presenting thereof on a display. Elasticity profile of vaginal tissue is calculated from the tactile response recorded from different parts of the probe during its insertion, from the static pressure pattern and from the dynamic tactile pattern. Pelvic floor muscle strength is defined as a contact pressure increase detected on fixed probe surface under the muscle contraction. Tactile profile of vagina is determined using the static tactile pattern, the elasticity profile and pelvic floor muscle strength.

  • Publication number: 20120277632
    Abstract: The present invention relates to a transrectal probe and method for real time mechanical imaging of a prostate. The probe is equipped with dual-array pressure sensors—one on the probe head and another on the shaft of the probe spaced away from the head with an angular and linear offset forming an S-shaped transition between the shaft and the head of the probe. The addition of the shaft pressure sensor array together with orientation tracking sensors allows precise calculation of the current head position throughout the examination of the prostate. Display means are used to guide the user in the proper manipulation of the probe in order to reduce the forces on surrounding tissues and organs and to minimize patient's discomfort.

  • Publication number: 20120259247
    Abstract: Methods for assessment of pelvic floor conditions based on tactile imaging are described. The vaginal wall is deformed before and after an interventional procedure using a transvaginal probe equipped with tactile pressure sensors and a motion tracking sensor. The vaginal wall coordinates and pressure patterns are obtained during the examination and used to build 3-D tactile image of the vagina and to calculate elasticity modulus profiles and spacing profiles along selected lines inside 3-D tactile image. The “before” and “after” profile values at specified locations are then compared to each other and to thresholds or profiles for normal conditions of vagina and its support structures. Methods of the invention may be used in estimating an improvement after an interventional procedure such as pelvic tissue regeneration, muscle repair or implantation of a supporting structure.

  • Patent number: 8142368
    Abstract: A novel method for soft tissue characterization includes obtaining a sequence of surface stress patterns as a function of an increasing compression force when a probe is pressed against the tissue over the location of the lesion of interest. A number of elasticity features are then calculated to characterize the tissue and the lesion located therein including strain hardening, loading curve average slope, lesion peak signal under a predetermined load, tissue heterogeneity, lesion shape and lesion mobility. At least three elasticity features are provided as an input to a statistical Bayesian classifier trained on a clinical database to calculate the probability of the lesion being benign or malignant. Additional patient-related parameters may be further provided as inputs to the classifier to increase the accuracy of differentiation between benign and malignant lesions.

  • Patent number: 8069735
    Abstract: A tactile sensor array includes a first electrode layer and a second electrode layer with a two-phase compressible dielectric material therebetween. A ferroelectret film is used as a dielectric layer. In some embodiments, to improve sensor sensitivity and at the same time provide for high stability and reproducibility of sensor readings, the ferroelectret film is vented to atmosphere via a venting network of channels traversing at least one electrode layer and a curved rigid substrate. In some embodiments, an elastic supporting structure is provided that comprises individual elastic fastening elements connecting all layers of the sensor together. These individual elastic fastening elements are located throughout the layers of the sensor and prevent cross-talk between the individual sensors that may be caused by local shifts of parts of the sensor during use.

  • Patent number: 8052622
    Abstract: Methods for characterizing elasticity of vaginal tissue are provided. A transvaginal probe is used to deform vaginal tissue during examination. The probe is equipped with pressure sensors and a motion tracking sensor. Stress and strain data is recorded during examination. Elasticity of vaginal tissue is then characterized by calculating a stress gradient defined as a ratio of stress over strain for each point of measurement. Vaginal tactile image may also be compiled to include a family of surfaces representing locations of measurement points at predefined constant levels of stress. Pelvic organ abnormality condition may be detected if the stress gradient is below either a predetermined threshold or a normal stress gradient obtained from clinical data.

  • Publication number: 20110130685
    Abstract: The present invention relates to a method for real time mechanical imaging of a prostate with a transrectal probe. In the method, generating a composite two- and three-dimensional prostate mechanical image from a plurality of partial mechanical images extracted from pressure response data and a probe orientation data starts with examining the prostate by pressing a probe head pressure sensor array against it at various overlapping locations. Merging of partial mechanical images together is accomplished by analyzing an overlap between each subsequent and previous partial mechanical image. Finding the prostate is assisted with a supplemental pressure response data indicating the location of a sphincter known to be about 4-5 cm away from the prostate. Data processing is improved by including probe orientation data to further increase the accuracy and sensitivity of the method.

  • Patent number: 7931588
    Abstract: A comprehensive system for objective assessment of colonoscope manipulation includes a handgrip for collecting and transmitting colonoscope handling data including force and motion data; a patient pain monitor for collecting and transmitting data on the level of patient's pain and discomfort; and digital processing means for extracting useful features such as colonoscope tip advancement speed from colonoscope-provided video images. All data is wirelessly transmitted to an electronic unit for processing and displaying on a monitor. A colonoscopy procedure is properly conducted when certain shaft advancement causes appropriate tip advancement, all without an increased level of patient's pain. The system of the invention is aimed at providing objective assessment data allowing for safer and less painful colonoscopies.
