摘要： A catheter maps an electrical conduction pattern in an annular region of a heart. The catheter has a tubular shaft that has a pre-shaped curved distal section adjacent the distal end thereof, and at least one lumen extending between the distal end and the proximal end of the shaft, with a plurality of electrodes disposed on the distal section. A handle is attached to the proximal end of the shaft, with a steering mechanism provided at the handle for adjusting the curvature of the distal section, and a deflection mechanism provided at the handle for deflecting the distal section. The electrodes are positioned in a parallel plane separate from the shaft when the distal section is undeflected.

Such foamed article is superior in electric properties, and the coaxial cable having such insulating layer is superior in attenuation property. The material of the invention can obviate drying of the insulating layer, which contributes to an improved production efficiency of the coaxial cable and reduced production cost. In addition, the insulating material of the present invention is beneficially economical.

摘要： A foamable organic composition comprising a compound foamable to 50% or more comprising an organic polymer and a chemical foaming agent, and, as a physical foaming agent, at least one member selected from the group consisting of rare gases and carbon dioxide; and a method for producing a foamed article having a high expansion ratio by using said composition. According to the present invention, a foamed article having a uniform and fine foam structure and a high expansion ratio of not less than 75% (which is as high as when freon gas is used) can be obtained without causing environmental problems such as depletion of the ozon layer. When applied, in particular, to a foamed layer for an insulated conductor, such as foam-insulated electric wire which is required to have high performance insulation and is occasionally installed under severe conditions, the composition of the present invention advantageously provides an insulated conductor with no potential buckling.
