摘要： A bioabsorbable stent for placement at the locus of a stenotic portion of a body passage, such as a blood vessel, which is flexible and compliant for safe and effective delivery to the site of the stenotic portion of, for example, a blood vessel, and so as to avoid the disadvantages of chronic implantation, such as arterial rupture or aneurism formation while exposed to the continuous stresses of a beating heart. The stent is formed from a bioabsorbable material and is porous or has apertures defined there through to facilitate tissue ingrowth and encapsulation of the stent. The stent is encapsulated and biodegrades or bioabsorbs within a period of days, weeks or months as desired following encapsulation to thereby minimize the likelihood of embolization or other risks of the dissolved material and to avoid the disadvantages of chronic implantation.

摘要： A method and apparatus is disclosed to reduce power consumption of a load. In one embodiment a power control system selectively routes power directly to a load or to a power reduction device. A delay may occur prior to introduction of the power reduction device to fully energize the load. The power reduction device may operate in conjunction with signal modification device. The signal modification device modifies the signal provided to the load to achieve desired operation of the load. In one embodiment the power reduction device comprises a step-down transformer and the signal modification device comprises a capacitor. In one embodiment the power reduction device is selected to remove unwanted frequency components from the signal provide to the load. In various other embodiments the power control system may be configured to stagger start the load to minimize the peak draw of the load.
