The present invention relates to a pressure sensor module for use in catheters having a pressure sensor operable to provide a signal representative of pressure. According to the source sheet and plate manufacturing method of the present invention, the plate for the stencil printing can be obtained which is superior in the pore block property and in which the thermal deformation of the source sheet during the plate manufacturing is suppressed. A tamper-evident seal may be provided encasing the slider device to provide indication whether access has been gained to the interior of the package. Front and rear mounting assemblies are provided for mounting the engine to the chassis. Therefore, the cutting tool is supported in an axial direction by the housing.
