20100121424 | Stent compression tool - The stent compression tool is used to install a diametrically compressible stent in a delivery catheter. The tool has a tubular configuration with a larger funnel mouth at one end and a narrower opening at the opposite end. The basic steps in the process comprise extending the stent carrying member from its catheter sheath, passing the carrying member through the tool from the narrower end thereof, placing the stent over the carrying member and compressing the stent by pushing it through the funnel mouth of the tool and the narrower lumen of the tool, inserting the stent grip member of the delivery catheter into the stent and further into the tool, pushing the end of the sheath into the end of the tool, using the carrying member and its stent grip to draw the compressed stent from the tool into the sheath, and removing the tool from the carrying member. | 05-13-2010 |
20110087336 | SELF-EXPANDING PLASTIC STENT - The self-expanding plastic stent is a resilient plastic stent with such expansional strength that a small diameter delivery system may be used to implant the stent, thereby minimizing possible complications for the patient. The stent is made from a braided monofilament, which may be polyetheretherketone (PEEK), polyetherketone (PEK), polyetherketoneketone (PEKK), polyaryletherketone (PAEK), polyetherketoneether-ketoneketone (PEKEKK), or any blends and alloys of these particular resins. The plastic stent may or may not be covered with polymer film. When used, the polymer film includes materials based on polyurethanes, silicones, or materials that biodegrade or erode in the body. Specifically the biodegradable materials might include poly-L-lactide, poly-D-lactide, polyglycolide, ε-caprolactone (epsilon-caprolactone), starch, and collagen or its polymer blends, alloys or copolymers. This material is heat-treated. The monofilament preferably has a diameter of 0.2-0.7 mm. The self-expanding plastic stent demonstrates better mechanical features, processibility, and shape memory. | 04-14-2011 |

20080258829 | Integrated quartz oscillator on an active electronic susbtrate - An oscillator having a quartz resonator, and a base wafer containing active electronics, wherein the quartz resonator is bonded directly to the base wafer and subsequently hermetically capped. | 10-23-2008 |
20090189294 | LARGE AREA INTEGRATION OF QUARTZ RESONATORS WITH ELECTRONICS - Methods for integrating quartz-based resonators with electronics on a large area wafer through direct pick-and-place and flip-chip bonding or wafer-to-wafer bonding using handle wafers are described. The resulting combination of quartz-based resonators and large area electronics wafer solves the problem of the quartz-electronics substrate diameter mismatch and enables the integration of arrays of quartz devices of different frequencies with the same electronics. | 07-30-2009 |
20100033062 | LOW FREQUENCY QUARTZ BASED MEMS RESONATORS AND METHOD OF FABRICATING THE SAME - A method for fabricating a low frequency quartz resonator includes metalizing a top-side of a quartz wafer with a metal etch stop, depositing a first metal layer over the metal etch stop, patterning the first metal layer to form a top electrode, bonding the quartz wafer to a silicon handle, thinning the quartz wafer to a desired thickness, depositing on a bottom-side of the quartz wafer a hard etch mask, etching the quartz wafer to form a quartz area for the resonator and to form a via through the quartz wafer, removing the hard etch mask without removing the metal etch stop, forming on the bottom side of the quartz wafer a bottom electrode for the low frequency quartz resonator, depositing metal for a substrate bond pad onto a host substrate wafer, bonding the quartz resonator to the substrate bond pad, and removing the silicon handle. | 02-11-2010 |
