Title: Stent and method for adjusting its treatment by changing amount of heparin applied on the stent
Inventor: LUNN ANTHONY C
IPC: A61F2/82
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To to greatly change the thrombotic resistance of a surface by applying heparin on a stent in such a manner that the level of antithrombin III activity may be changed. SOLUTION: An antithrombin agent, such as heparin, is applied on the wall 12 of the stent 10. A carmeda CH 5 heparin coating is applied on, for example, JJIS Palmaz shatz crown stent. As a result, platelet deposition decreases substantially during the period when the stent 10 is exposed to the flowing blood in an AV-shunt. The suppression of the platelet deposition is greatly changed by the height of the antithrombin III activity of the heparin coating on the surface of the stent 10. Namely, the suppression of the platelet deposition increases as the antithrombin III activity increases to about 0.7, about 0.8... about 5.0 picomol/stent. Then, the stent 10 is more installed to the lesion section as the heparin is applied more on the stent. Thrombus formation is lessened when the stent is expanded beyond its elasticity threshold.

Abstract: PURPOSE:To easily form a small length gate by forming second single crystal semiconductor on a first semiconductor substrate, selectively performing anisotropic etching, and forming a gate by eliminating the second semiconductor in a manner in which the aperture width of the bottom part is made smaller than that of the upper part. CONSTITUTION:An AlGaAs layer 2 is formed on a GaAs substrate 1 by a molecular beam epitaxial method excellent in the controllability of film thickness. Photoresist 3 is selectively formed, and etching shown by figure (c) is performed, by using etching liquid whose etching rate of a lower surface is small as compared with that of an upper surface. When a gate electrode 4 is formed, its gate length becomes 0.25mum. In this manner, because of anisotropy of etching of single crystal, a gate shorter than the gate length formed by a photolithography method can be formed.

Upon receipt of the state code from the memory 84, a CPU 80 compares the state code with the content of a state code table within a control ROM 81, thereby recognizing the state of the printer. The recognized state is displayed by a display device 30. At the same time, the state code and voice patterns for a necessary procedure are extracted from a voice pattern generator 83 in a chain reacting manner in accordance with the content of the control ROM 81, which are then demodulated in a voice synthesizing part 45, changed to analog voice signals by a D/A converter 44 and output from a speaker 40.
