20090313798RUGGED PIEZOELECTRIC ACTUATORS AND METHODS OF FABRICATING SAME - Processes of fabricating an actuator comprises bonding an unpolled element to a substrate and thereafter poling the bonded element for providing the element with an electro-active response property. In differing modes of the process, the unpolled element can comprise one or more of (for example) a piezoelectric material (e.g., lead zirconate titanate); a piezorestrictive material; and/or a ferroelectric material. Actuators fabricated by the processes are also described.12-24-2009

20100145306Various Catheter Devices for Myocardial Injections or Other Uses - A catheter device comprising a proboscis shaft and a proboscis disposed within the proboscis shaft. In certain embodiments, the catheter device further comprises an elongate tubular member, wherein the proboscis shaft is disposed within the elongate tubular member. In certain embodiments, the catheter device comprises a tissue surface engagement structure, which has a first configuration and a second configuration. In the second configuration, the tissue surface engagement structure presents a larger transverse profile in comparison to the first configuration. The tissue surface engagement structure may have any of various designs, including an expandable assembly and a hinged assembly. In certain embodiments, a deformable cushion is positioned at the distal end of the proboscis shaft. The deformable cushion comprises a pocket that is filled with a reshapeable material. In certain embodiments, the proboscis shaft comprises a longitudinally compressible portion.06-10-2010

20090301480DIAGNOSTIC SAMPLE COLLECTION SYSTEM AND METHOD OF USE - A bronchoalveolar lavage instillation/aspiration system which includes (i) a needleless bronchoalveolar lavage instillation/aspiration device with a barrel member including a barrel lumen having a distal aperture and a self-sealing member configured for maintaining a fluid-disruptable, resealable barrier to the distal aperture; and (ii) a catheter assembly configured to provide a patent path of fluid communication between the instillation/aspiration device and a patient bronchial passage, where the catheter includes a wedging structure configured to engage a patient bronchial passage. In another aspect, embodiments of the present invention may include one or more methods of making and using a system or component described herein.12-10-2009
20090306545BRONCHOALVEOLAR LAVAGE CATHETER ASSEMBLY - A catheter assembly configured for use in a non-bronchoscopic bronchoalveolar lavage procedure. The catheter assembly may include an inner catheter member having an inner catheter lumen and an outer catheter member having an outer catheter lumen, where the inner catheter member is disposed longitudinally and coaxially through at least a lengthwise portion of the outer catheter lumen, a distal end portion of the outer catheter includes an atraumatically-shaped disruptable seal—which seal includes at least a pair of overlapping slits that extend at least partially through an internal distal end wall portion of the outer catheter—and where a distal end portion of the inner catheter includes a wedging structure configured to at least partially sealingly contact an inner circumference of a passage in a lower portion of a patient lung.12-10-2009

20080265700High current capacity rectifier package - Disclosed is a dynamoelectric machine having improved heat dissipation capabilities. The dynamoelectric machine includes a three-phase stator winding with a rectifier assembly electrically connected to the stator winding. The rectifier assembly includes an end frame having at least one negative diode contained therein and a positive heat sink which has at least one positive diode disposed therein. Connecting the negative diodes and positive diodes is a terminal assembly. The terminal assembly includes one or more electrically conductive and heat dissipative straps. The straps electrically connect one or more negative diodes and one or more positive diodes. Also disclosed is a method for dissipating heat from a rectifier of a dynamoelectric machine.10-30-2008
20100072838COIL SUPPORT FOR ROTATING ELECTRICAL MACHINE - Disclosed is a coil support for an electrical machine including a shank having a first outer diameter configured to support a field coil of the electrical machine and a base located at one end of the shank. The base has a second outer diameter greater than the first outer diameter and includes a plurality of recesses configured to increase a cooling flow through the electrical machine. Further disclosed is an electrical machine including the coil support and a method for cooling an electrical machine.03-25-2010
