| 20080312432 | Stabilizers for Use in Nvp Synthesis - A process for preparing N-alkenyl compounds by reacting the corresponding NH compounds with alkynes in the liquid phase in the presence of a catalyst, wherein the reaction is carried out in the presence of at least one stabilizer, and the use of stabilizers for increasing the selectivity in a process for preparing N-alkenyl compounds by reacting the corresponding NH compounds with alkynes in the liquid phase in the presence of a catalyst. | 12-18-2008 |
| 20090253938 | Method for Producing 1,2-Diamino-3-Methylcyclohexane and/or 1,2-Diamino-4-Methylcyclohexane - A process for preparing 1,2-diamino-3-methylcyclohexane and/or 1,2-diamino-4-methylcyclohexane by reacting 2,3- and/or 3,4-diaminotoluene with hydrogen at elevated pressure and elevated temperature in the presence of a heterogeneous rhodium catalyst, wherein a mixture comprising 2,3- and/or 3,4-diaminotoluene, a dialkyl ether and/or alicyclic ether as a solvent and ammonia is initially charged in an autoclave in the presence of the catalyst and subsequently hydrogenated while supplying hydrogen. | 10-08-2009 |

| 20100082059 | RADIAL COIL EXPANDABLE MEDICAL WIRE - An expandable medical wire can be used to entrain biological or foreign material during a medical procedure, such as lithotripsy. The wire also can be used to remove the material safely from the body. Generally, the wire includes a sleeve and a core, where the sleeve, the core, or both include a portion or portions that can be deployed to form an expanded coiled configuration. The expanded coiled configuration can be collapsed to facilitate positioning the wire within an anatomical lumen. In addition, the wire can be used as a conventional guide wire or as a self-anchoring guide wire. | 04-01-2010 |
| 20100121279 | Apparatus and Method for Establishing Access to the Body - An apparatus and method for access to the inside of a body includes a transparent sheath with a radiopaque marking and fastener for securing a guidewire or catheter. The transparent sheath permits objects located within and near the sheath to be visualized with an external imaging system. Objects located near the sheath can also be observed with an imaging device disposed inside the sheath. The radiopaque marker permits accurate positioning of the sheath in the body. The sheath can be inserted into the body over an interventional device. A fastener prevents migration of a guidewire or catheter during the procedure. | 05-13-2010 |

| 20090035447 | METHODS OF MAKING DISPOSABLE GLOVES - A disposable glove and a method for making the disposable glove that reduces or eliminates glove cuff roll-down. The disposable glove includes a coating on the interior surface of the glove that extends from the hand area to a portion of the wrist-forearm area of the glove but does not include coating on the portion of the wrist-forearm area containing the beaded cuff and cuff portion. The uncoated portion of the interior surface of the disposable glove resists glove cuff roll-down when the glove is positioned on a user's hand and forearm. | 02-05-2009 |
