An electrosurgical method and apparatus comprises a probe, at least one temperature sensor, and a controller for generating and controlling electromagnetic energy supplied to the probe. The controller receives signals from the temperature sensor and controls the supply of electromagnetic energy such that the temperature of the probe is ramped up and then maintained at a steady state temperature of between 100° C. and 115° C. In an equilibration phase, between the ramping up and the steady state temperature, the controller holds the temperature of the probe substantially constant for a period of time to allow the temperature of different parts of the probe to equilibrate.

A support surface, such as an underpad, for preventing pressure sores in a patient is a multi-layer textile assembly having a skin contact layer formed from a fabric of synthetic filament yarns woven to provide air permeability and moisture vapor permeability and having a thickness of less than 1 mm. An absorbent middle layer is formed from a breathable microfiber fabric woven to provide for moisture transition from an upper surface of the middle layer to a bottom surface of the middle layer. The skin contact layer and the middle layer are stitched together using a stitching pattern optimized to produce an open pattern with minimal puckering. A bottom layer is formed from a breathable, waterproof fabric woven from synthetic yarn to produce a moisture vapor transfer rate within the range of 5,000 to 20,000 grams per meter squared per 24 hours. The three layers are attached together around their outer edges.

The invention is based on the discovery that certain membranes, which include side chains or molecular “brushes” having, for example, tertiary amino functional groups, can be used as highly effective filters to capture viruses/virus particles from liquids without removal of proteins. New methods based on this discovery include removing viruses from liquids such as blood or plasma, removing viruses from pharmaceuticals, concentrating and/or purifying viruses, e.g., for use in gene therapy, and producing recombinant viruses in new bioreactors. The invention also includes new methods of therapy or adjunct therapy for viral infections, in which a patient's blood or plasma is filtered through the membranes to remove viruses to reduce the viral load. The invention also includes new bioreactors and viral filters containing the membranes.
