An intra-luminal device for the extraction of occlusive or partially occlusive material is disclosed. The anisotropic conductive sheet has a conductive property in a thickness direction thereof under a predetermined condition, and includes: insulative matrix members having a dielectric constant value of at most 2. Thus, an output buffer circuit capable of driving an output pad with optimal driving capabilities in a normal operation mode and in a test operation mode in a semiconductor device for use in a system in package is implemented. There is a top isolation diaphragm member which is convoluted and to which a force is applied which applied force is transmitted to the thin flexible beams. The guide tube has an end in communication with the channel and an opposite end positioned on the blade to guide the adhesive dissolving liquid contained in the channel to the blade.
