20090247724POLY(ARYLENE ETHER) COPOLYMER - A poly(arylene ether) copolymer is the product of oxidative copolymerization of monomers including a monohydric phenol and a dihydric phenol. It has an intrinsic viscosity of about 0.04 to about 0.15 deciliter per gram and, on average, about 1.8 to about 2 hydroxyl groups per molecule. The poly(arylene ether) copolymer is enriched in low molecular weight copolymer chains and copolymer chains that include a terminal unit derived from the dihydric phenol.10-01-2009

20090043327Split sheath for trocar assembly - A trocar assembly including a trocar and a trocar sheath and methods for accessing an intracorporeal site, e.g. biopsy or trocar site, using the trocar assembly. The trocar has a tissue penetrating distal tip, an elongated shaft and a proximal handle portion. The distal portion of the trocar sheath forms a releasable connection, such as a friction fit, with the shaft of the trocar and a slit that extends from the distal portion to the proximal end of the trocar sheath. The trocar assembly is advanced through the patient's tissue until the distal end of the trocar sheath is located at the desired site and then the trocar is removed. A treatment device such as a radiation balloon catheter is advanced through the interior of the sheath until the treatment component thereof is at the desired site.02-12-2009

20110290859RIBBON BONDING TOOLS AND METHODS OF USING THE SAME - A ribbon bonding tool including a body portion is provided. The body portion includes a tip portion. The tip portion includes a working surface between a front edge of the tip portion and a back edge of the tip portion. The working surface includes a region defining at least one of a plurality of recesses and a plurality of protrusions. The working surface also defines at least one of (1) a first planar portion between the region and the front edge of the tip portion, and (2) a second planar portion between the region and the back edge of the tip portion.12-01-2011

20090297786RIBBON BONDING TOOL AND PROCESS - An ultrasonic bond is formed using a bond tool foot having a waffle shape of thin protrusions and gaps between the protrusions. The tool is brought in contact with the ribbon to a depth to create depressions in a ribbon approximately 150 μm or less from the underlying bonding surface. The tool is then brought down further into the ribbon to contact the portions of the ribbon between the depressions, such as an additional 25 to 50 μm. The result is lightly bonded regions underneath the groove portions and highly bonded regions underneath the protrusions and around the perimeter of the bond. In another embodiment, an ultrasonic bond is formed along a partial width of a ribbon.12-03-2009
