  • Patent number: 10945650
    Abstract: Inside a connector body (112, 114; 300) of a medical connector providing a fluid flow conduit, a one-way valve (118) is fitted directly into one end of a stop valve (116) in a manner providing a fluid tight seal between these valves. The stop valve (116) prevents fluid flowing out of the end (111; 311) of the connector body (112, 114; 300) unless a complementary end of a separate device (not shown), typically a Luer lock connector, engages the end of the connector body and opens the stop valve (116). To facilitate manufacture and assembly, the one-way valve (118) and the stop valve (116) can be formed as parts of a single piece of elastomeric material, the parts being hingedly connected so that the one-way valve part (118) can be folded over to be fitted directly into the end of the stop valve part (116). A further possibility, also applicable when only a stop valve (116) is provided, is that the connector body (300) may be formed in one piece with a folding, snap fit closure (312).

The first opening is sized for a first fluid flow component to couple to the housing, and the second opening for a second fluid flow component. The first and second fluid flow components include first and second fluid-carrying channels of different diameter, with the first fluid-carrying channel having a first channel diameter that is larger than the second channel diameter of the second fluid-carrying channel. A tapering element is associated with the housing and extends into the first fluid-carrying channel. The tapering element includes a tapering fluid-carrying channel which tapers in a direction back towards the housing, for instance, from about the first channel diameter to about the second channel diameter.

  • Patent number: 10376219
    Abstract: A monitoring device for the circulation of a patient includes sensors for recording data, an input unit for inputting patient specific data and a connected a data recording and analysis device configured to determine the right atrial pressure (RAP), the mean arterial pressure (MAP) and the cardiac output (CO) and to determine the mean systemic filling pressure (Pms) and to determine the cardiac efficiency (Eh) therefrom. A device records a pressure value (Pps,char) characterizing the pressure assistance during positive-pressure ventilation. The data recording and analysis device is configured to determine a pressure-corrected mean systemic filling pressure (Pmsp) and a pressure-corrected cardiac efficiency (Ehp) by the difference from the right atrial pressure (RAP) and the pressure value (Pps,char) characteristic of the pressure assistance being used instead of the right atrial pressure (RAP).

  • Patent number: 10327695
    Abstract: The present invention generally relates to methods, systems, and apparatuses for determining the degree of improvement after a therapeutic procedure. The method can involve determining a baseline measurement prior to conducting a therapeutic procedure, conducting the therapeutic procedure, and determining a post-therapy measurement after conducting the therapeutic procedure. The method further involves comparing the post-therapy measurement to the baseline measurement, thereby determining the degree of improvement after conducting the therapeutic procedure.

  • Patent number: 10321958
    Abstract: Embodiments include a system for determining cardiovascular information for a patient. The system may include at least one computer system configured to receive patient-specific data regarding a geometry of the patient's heart, and create a three-dimensional model representing at least a portion of the patient's heart based on the patient-specific data. The at least one computer system may be further configured to create a physics-based model relating to a blood flow characteristic of the patient's heart and determine a fractional flow reserve within the patient's heart based on the three-dimensional model and the physics-based model.

  • Patent number: 10274408
    Abstract: Embodiments of the invention include a biosensor, such as an implantable biosensor, that includes a sensor material sensitive to at least one analyte in a pressure measurement chamber coupled to a pressure sensor. In embodiments of the invention, a pressure prevailing in the pressure measurement chamber may be determined by the pressure sensor. The sensor material is coupled in the pressure measurement chamber to a compensation material, which includes a relationship between a temperature and a volume of the pressure. The relationship is opposite to a temperature-dependent change in pressure or volume of the sensor material and at least partially compensates for a cross-sensitivity-induced change in volume of the sensor material.

  • Patent number: 10201284
    Abstract: Bending stresses experienced by a pressure sensor mounted to a fractional flow reserve catheter when tracking the catheter through the vasculature creates a distortion of the sensor resulting in an incorrect pressure reading or bend error. In order to isolate the sensor from bending stresses, the sensor is mounted with one end coupled to the distal end of the shaft while the other end of the sensor is not coupled to the catheter so that a portion of the sensor is spaced apart from the distal end of the shaft.
