The invention relates to a tubular shaft instrument for separating tissue. In conventional tubular shaft instruments the clean separation of tissue poses a problem. In practice, it is often the case that e.g. as a result of wear to the blade, the tissue is severed by the active force rather than by the action of the blade. The cut edges are also deformed accordingly. The invention relates to a tubular shaft instrument that guarantees a significantly more reliable, cleaner separation of tissue. To achieve this, in contrast to conventional cutting devices, the blade is not displaced through the fixed tissue, but glides over the latter until a complete separation is determined.

A filter element for end face inlet formed of triangular channels which are alternately closed such that the fluid to be filtered must pass through the filter material in order to flow from the inlet side (22) to the discharge side (23). The channels are formed by alternating flat layers (17) and folded layers (18), whereby all sides of the inlet channels face a discharge channel. A particularly high filter efficiency is thereby achieved such that a large filter surface area and a high filter capacity are attained with a relatively small structural volume. The filter can be used, for example, as an air filter for various air filtration applications.

A capacitive fluid level sensor is disclosed that operates without the use of a float, wherein coplanar sensing electrodes disposed onto a dielectric substrate and positioned proximate a dielectric wall of a vessel containing a fluid, form a fringing field capacitance that changes in accordance with changes in the level of the fluid. The electrodes are electrically insulated from the measured fluid. The electrodes are sized and spaced to maximize response of the capacitance to changes in the level of the fluid, while minimizing the effects of the dielectric wall. The sensor is fabricated such that it can be positioned against the outside of a dielectric wall of a vessel, or embedded within a dielectric material. A low permitivity spacer and shield assembly are taught which reduces sensitivity to electric fields external to the vessel. An interdigital comb configuration of the electrodes is also disclosed in which depressions or gaps are formed into the dielectric substrate in an area of spacing of the electrodes.

A method for multi-slice magnetic resonance imaging, in which image data is acquired simultaneously from multiple slice locations using a radio frequency coil array, is provided. By way of example, a modified EPI pulse sequence is provided, and includes a series of magnetic gradient field “blips” that are applied along a slice-encoding direction contemporaneously with phase-encoding blips common to EPI sequences. The slice-encoding blips are designed such that phase accruals along the phase-encoding direction are substantially mitigated, while providing that signal information for each sequentially adjacent slice location is cumulatively shifted by a percentage of the imaging FOV. This percentage FOV shift in the image domain provides for more reliable separation of the aliased signal information using parallel image reconstruction methods such as SENSE. In addition, the mitigation of phase accruals in the phase-encoding direction provides for the substantial suppression of pixel tilt and blurring in the reconstructed images.
