Abstract: A device (2) for capturing and removing particles (58) from a body canal or vessel includes a sack (12) having a mouth (14) and a closed bottom (16) opposite mouth (14). A guide wire (4) is received through mouth (14) of sack (12) and is connected to closed bottom (16) of sack (12). A collapsible frame (8) is connected between guide wire (4) and mouth (14) of sack (12), with collapsible frame (8) biasing mouth (14) of sack (12) opened around guide wire (4). A containment collar (32) slidably receives guide wire (4), collapsible frame (8), and at least part of sack (12) therein. A pull wire (34) is connected to containment collar (32). Collapsible frame (8) can move from inside containment collar (32) where mouth (14) of sack (12) is closed and outside containment collar (32) where mouth (14) of sack (12) is biased open by collapsible flame (8).

Abstract: A method of upgrading a 1,500 rpm reactor coolant pump motor having a vertically oriented rotor shaft supported by a lower guide bearing disposed in an oil reservoir. The method includes removing a lower guide bearing support to enhance circulation of the oil to facilitate cooling of the oil and operating the reactor coolant pump motor at 1,500 rpm without the lower guide bearing support or the oil baffle or flinger ring attached to the lower guide bearing support. The method further includes thickening a keeper to support the guide bearing.

Abstract: A device (2) for capturing and removing one or more particles (58) from a body canal or vessel includes a sack (12) having a mouth (14) and a closed bottom (16) opposite mouth (14). A guide wire (4) is received through mouth (14) of sack (12) and is connected to closed bottom (16) of sack (12). A collapsible frame (8) is connected between guide wire (4) and mouth (14) of sack (12), with collapsible frame (8) biasing mouth (14) of sack (12) opened around guide wire (4). A containment collar (32) slidably receives guide wire (4), collapsible frame (8), and at least part of sack (12) therein. A pull wire (34) is connected to containment collar (32). In response to relative movement between guide wire (4) and pull wire (34), collapsible frame (8) moves from inside containment collar (32) where mouth (14) of sack (12) is closed and outside containment collar (32) where mouth (14) of sack (12) is biased open by collapsible frame (8).

Abstract: A dynamic port that extends from the bottom wall of an oil reservoir that surrounds the lower guide bearing of a reactor coolant pump and is in fluid communication within an oil level gauge. The dynamic port is rotatable into and out of the oil flow path to adjust the dynamic oil level shown by the oil level gauge when the pump is at operating speed to be substantially equal to the static oil level when the motor is at rest.

Abstract: A device for capturing and removing particles from a body canal or vessel includes a sack having a mouth and a closed bottom. A guide wire received through the sack mouth is connected to the closed sack bottom. A collapsible frame biases the sack mouth opened around guide wire. A containment collar slidably receives guide wire, collapsible frame, and at least part of sack therein. A pull wire is connected to the containment collar. In response to relative movement between guide wire and pull wire, collapsible frame moves from inside the containment collar where the sack mouth is closed and outside the containment collar where mouth of sack is biased open by collapsible flame.

Abstract: An apparatus for removing a solid object from a body canal or vessel includes a coil of wire configured to slidably receive a guide wire and a sack having a mouth and a closed bottom opposite the sack. A resilient frame is connected between the coil of wire and the sack for biasing the mouth of the sack open around the coil of wire. The resilient frame is positionable between a collapsed state where the mouth of the sack is closed against the bias of the resilient frame and a deployed state where the mouth of the sack is biased open by the resilient frame.

Abstract: An implantable distractor that provides controlled forceful movement either to facing bone ends created by osteotomy or across cranial sutures for the purpose of fostering bone deposition to support bone growth (distraction osteogenesis). The improved Distractor adjusts separation of such through precise, forceful, incremental movements. The mechanism has an actuator powered by intermittent electrical current flow through a shape-memory-effect (SME) actuation component. The SME component deforms forcefully. This force is amplified to result in incremental separation of two plates affixed to bone on either side of the osteotomy or suture.
