  • Publication number: 20240115795
    Abstract: A vacuum therapy device for treatment of a defect internal of a human or animal body, the device comprising: a suction tube extending from: (i) a proximal portion for coupling to a source of negative pressure outside the body, to (ii) a distal portion for providing suction proximal to the defect when inserted into the body; a porous medium coupled to the distal portion of the suction tube to provide suction to the defect when inserted into the body for treatment thereof; and a constraining sleeve for selective compression of the porous medium, the constraining sleeve having a proximal end and a distal end, wherein the constraining sleeve is movable relative to the porous medium between: an insertion position in which the proximal and distal ends of the sleeve are arranged at the distal portion of the suction tube so that the sleeve at least partially surrounds the porous medium to retain the porous medium in a compressed state during insertion into the body; and a treatment position in which the porous medium

  • Patent number: 11733198
    Abstract: A method for determining a concentration of an analyte in a fluidic sample is described. A sample is applied to a biosensor including an electrochemical cell having electrodes. A predetermined voltage waveform is applied during at least first and second time intervals. At least first and second current values are measured during the first and second time intervals, respectively. A turning point time is determined during the first time interval at which the measured first current values transition from a first to a second profile. The concentration of analyte in the sample is calculated based on determined turning point time and at least one measured current value. In another example, a physical characteristic of the sample is estimated based on measured current values. The concentration is calculated using a first or second model if the estimated physical characteristic of the sample is in a first or second range, respectively.
