Abstract: A catheter tip pressure transducer for detecting the pressure in various portions of a living body accurately and safely comprises a pressure sensor disposed within the end portion of a catheter. The pressure sensor comprises a pressure sensitive diaphragm whereon strain gauges are formed by a diffusion method. The pressure sensor is mounted on an insulated supporting member without being secured firmly thereto. A protecting member made of silicone rubber fills the hollow portion of the catheter so as to isolate and protect the pressure sensor and the ambient body tissue.Pressure is accurately measured by the pressure sensor without being influenced by the thermal stresses which occur in the supporting member. Furthermore, electrical isolation and mechanical safety are obtained.

Abstract: An intracranial pressure transducer includes a casing comprising an annular member having a screwed part on an outer wall thereof for fitting and securing a skull of a body. A pressure-electric transducing portion including a supporting member which is inserted within an inner wall of the casing and is tightly fixed to the predetermined upper portion from a tip portion of the casing, an indicating circuit for indicating the intracranial pressure in response to an output of strain sensitive elements, and indicating means.

Abstract: A metal body having a very large surface area and high porosity, useful as a gasoline vaporizer, a heat exchanger for automobiles, a catalyst or catalyst carrier, a filter, or the like, and composed of a plurality of metal fibers which are entangled with one another to form a bed or stratum, the metal fibers being coated with a metal in such manner that the stratum provides rough and complex surfaces with cracks and irregularities. The invention also includes a process for making said metal body including the steps of entangling metal fibers to form a bed, placing the bed of fibers in contact with a coating metal, heating the fiber bed and coating metal so as to wet the fibers with molten coating metal, and cooling.
