A main body (10) of a percutaneous administration device is formed from a resilient biodegradable resin, such as an elastomer resin or a silicone rubber, and includes a substrate (12) and multiple micropiles (14) formed on the substrate. The leading ends of each micropile (14) is shaped with a flat contact face (14A) that stops upon the contact with the skin and does not perforate the skin. Depressed portions (18) are formed in the contact face (14A). The depressed portions hold a functional substance (16) having a whitening effect, such as powdered or liquid vitamin C or provitamin C, or fine ceramic particles impregnated with vitamin C.


A device for isolating periphery circulating tumor cells or rare cells includes a metal filter having depressions that can capture periphery circulating tumor cells or rare cells that are in a body fluid, and pores that are formed at the depressions and that can pass therethrough body fluid cells other than periphery circulating tumor cells or rare cells.

A stent that is extremely useful in practice, with excellent proof stress (elastic limit stress). The stent (1) is in a tubular shape that is expandable in a radial direction, the stent being placed in a tubular vessel of a living body. The stent (1) is formed of a main stent element (2) that is formed at an imaginary cylinder surface. The main stent element (2) is fabricated of an alloy with a proof stress of from 500 to 2700 MPa, or is fabricated of an electroformed alloy with a repetition fatigue strength at least 1.5 times the strength of a nickel member or a nickel/cobalt alloy member, which is an alloy containing any of gold, silver, copper, nickel, cobalt and palladium. Therefore, the stent (1) may be easily and uniformly expanded in the radial direction, and is not easily crushed in the radial direction after being expanded.

To provide a probe card that is used when carrying out electrical inspection of a high-density fine circuit board to be measured. A probe card has plural probe pins, an insulator having plural through-holes through which the probe pins pass, and a pair of substrates that are positioned at both sides of the insulator and that have supporting holes into which end portions of the probe pins are inserted respectively. The pair of substrates and the insulator are provided so as to be slidable. One substrate is formed of a material having a same value as or an approximate value of a coefficient of thermal expansion of a fine circuit board to be measured, and another substrate is formed of a material having a same value as or an approximate value of a coefficient of thermal expansion of a wiring board for signal input/output. By doing so, even if the fine circuit board to be measured and the wiring board for signal input/output thermally expand, the probe pins can always be made to contact the respective electrodes of the fine circuit board to be measured and the wiring board for signal input/output, and the probe pins that are adjacent do not short circuit. Therefore, electrical inspection of a high-density fine circuit board to be measured can be carried out at one time, and furthermore, precisely.
