Cell/tissue analysis via controlled electroporation
InactiveUS6482619B1The right amountAvoid cell damageBioreactor/fermenter combinationsBiological substance pretreatmentsBiological bodyElectrical resistance and conductance
An electrical current is created across an electrically conductive medium comprising a cell which may be part of a tissue of a living organism. A first electrical parameter which may be current, voltage, or electrical impedance is measured. A second electrical parameter which may be current, voltage or a combination of both is then adjusted and / or analyzed. Adjustments are carried out to facilitate analysis and / or obtain a desired degree of electroporation. Analysis is carried out to determine characteristics of the cell membrane and / or tissue.

Images created by electrical impedance tomography (EIT) are used to adjust one or more electrical parameters and obtain a desired degree of electroporation of cells in tissue. The parameters include current, voltage and a combination thereof. The cells are subjected to conditions such that they become permeabilized but are preferably not subjected to conditions which result in irreversible pore formation and cell death. The electroporation can analyze cell membranes, diagnose tissues and the patient as well as to move materials into and out of cells in a controlled manner.

Controlled electroporation and mass transfer across cell membranes
InactiveUS6403348B1The right amountAvoid cell damageBioreactor/fermenter combinationsElectrotherapyControl mannerCell membrane
Electroporation is performed in a controlled manner in either individual or multiple biological cells or biological tissue by monitoring the electrical impedance, defined herein as the ratio of current to voltage in the electroporation cell. The impedance detects the onset of electroporation in the biological cell(s), and this information is used to control the intensity and duration of the voltage to assure that electroporation has occurred without destroying the cell(s). This is applicable to electroporation in general. In addition, a particular method and apparatus are disclosed in which electroporation and / or mass transfer across a cell membrane are accomplished by securing a cell across an opening in a barrier between two chambers such that the cell closes the opening. The barrier is either electrically insulating, impermeable to the solute, or both, depending on whether pore formation, diffusive transport of the solute across the membrane, or both are sought. Electroporation is achieved by applying a voltage between the two chambers, and diffusive transport is achieved either by a difference in solute concentration between the liquids surrounding the cell and the cell interior or by a differential in concentration between the two chambers themselves. Electric current and diffusive transport are restricted to a flow path that passes through the opening.

Cell equalizing circuit
InactiveUS7061207B2Guaranteed maximum utilizationMaximize battery lifeCharge equalisation circuitElectric powerLithiumCharge current
An electric circuit for equalizing voltages between serially arranged cells. The circuit is operable to generate AC voltages at amplitudes dependent on the DC voltages of the received cells. The AC voltages are all connected to an inductive coupling circuit. The inductive coupling allows higher-voltage cells to induce a recharging current flow in lower voltage cells and so equalize the cell voltages. The circuit also operates to ensure that cell voltages are maintained in equilibrium during charging or discharging of received cells, irrespective of the individual charging and discharging characteristics of the cells. The circuit thus prevents individual cells in a battery from being over-charged or over-discharged and allows more efficient use of the full capacity of a battery without risking damage to the individual cells. The cell equalizing circuit is thus especially useful for rechargeable cells, such as lithium-ion cells, which are sensitive to damage by over-charging and over-discharging.

An improved anticoagulant is based on a higher level of citric acid than is usual (at least about 0.2% weight by volume). The higher citrate is combined with an amino acid as a counterion. The amino acid prevents cellular damage often caused by elevated citrate levels. The amino acid citrate mixture also serves to preserve platelet concentrates and platelet rich plasma during room incubation. Not only does the amino acid citrate combination enhance platelet integrity, it completely inhibits the growth of bacteria such as Staphylococcus epidermidis. Collecting blood of plasma into such higher levels of citrate prevents activation of blood proteins so that fractions made from the blood or plasma have superior characteristics.
