  • Patent number: 10512760
    Abstract: The cervical canal dilation device of the present invention relates to controlled injection of liquid or gel to the cervical canal in order to obtain a desired predetermined dilation while causing the treated woman minimal discomfort. The injection of a substance having a liquid or gel characteristics into the cervical canal is done while the inner and outer orifices (internal os and external os) of the canal are sealed by two reversibly inflatable balloons, referred to as the “dilating balloons”. An inflatable balloon at the tip or near the tip of the cervical canal dilation device anchors the device (in the uterine cavity linked to the internal os) to the desired position in the cervix canal for the dilation treatment. The amount of fluid or gel injected into the cervix canal can be calculated apriori to expand the width of the canal to the desired dimension.

  • Patent number: 8088105
    Abstract: A syringe pump including a syringe including a plunger that slides in a body which has a discharge port, a driving mechanism coupled to the syringe, including a cylinder in which a piston slides, and a plurality of biasing devices arranged about the piston operative to apply urging forces on the piston to drive the piston distally in the cylinder and thereby cause the plunger to slide in the body and discharge a substance found in the body through the discharge port, wherein if one of the biasing devices fails another of the biasing devices continues to apply a force on the piston to drive the piston distally in the cylinder, and a safety catch that initially prevents the biasing device from moving the piston, the safety catch being removable to permit the biasing device to move the piston.

  • Patent number: 7961311
    Abstract: System and method for detecting and counting bacteria suspended in a biological fluid by means of light scattering measurements is provided. In accordance with the method of the invention the level of signal to noise of the measured intensities of light scattered by a sample of the biological fluid is significantly enhanced for forwardly scattered light within a range of scattering angles which are smaller compared to a predefined maximal scattering angle. The system of the invention includes a cuvette adapted to contain a sample of the biological fluid whose sidewalls and windows are suitably constructed and arranged to significantly reduce the level of reflected light obscuring the scattering patterns measured within the range of scattering angles considered.
