| 20090053101 | Sterilization Method and Plasma Sterilization Apparatus - An object to be sterilized is disposed inside a vacuum chamber, and the inside of the vacuum chamber is evacuated. When the pressure inside the vacuum chamber reaches 3 Pa, a cutoff valve disposed between the vacuum chamber and the vacuum pump is closed. High-frequency power is supplied to an electrode. Oxygen gas is introduced into the vacuum chamber for 0.1 sec. Thereafter, the pressure is held constant for 3 sec. Until the pressure inside the vacuum chamber reaches 10 kPa, introduction of oxygen gas into the vacuum chamber is repeated. When the pressure reaches 10 kPa, the cutoff valve is opened to evacuate the inside of the vacuum chamber and the supply of the high-frequency power is stopped. Introducing the oxygen gas and determining pressure inside the vacuum chamber is repeated, and after 90 min, the pressure inside the vacuum chamber is returned to atmospheric pressure. | 02-26-2009 |
| 20090074610 | METHOD OF STERILIZING POLYMERIC STRUTS AND STENTS - It has been determined that gamma sterilization of biodegradable polymer stents does not cause significant polymer cross-linking and collapse. Using sufficient spacing can lead to stents that display little if any detrimental effects from the procedure. In certain embodiments, using structures in the general region of about 100 micron spacing between the struts leads to highly functional stents that do not fuse. Further, the resulting stent has radially homogenous mechanical properties. Therefore, the stent has a uniform expansion within the lumen. | 03-19-2009 |
