摘要:
Methods, devices and systems are described for treating venous insufficiency in which the vein is compressed at least partially along a treatment zone. A system can be provided including an injection device, such as a glue gun, that is operably connected to a delivery catheter that can be advanced across a treatment zone in the vein. The delivery catheter can be used to deliver one, two, or more boluses of media (e.g., cyanoacrylate) to occlude the vein along different spaced-apart sections of the treatment zone. External compression can also be applied to the vein by a compression element, such as a hand or multifunctional ultrasound transducer, to occlude portions of the vein along the treatment zone prior to or during the introduction of the boluses of media.

摘要:
Methods and devices for providing improved ultrasound visibility of medical devices intended for intravascular use are described. The inclusion of gas/solid boundary regions within a medical devices improves the resolution of the device under ultrasound visualization. Gas/solid boundary regions may be provided through the use of embedded gas-filled microlumens, microwells, or enclosed pockets within the medical device.

A circuit breaker assembly includes a housing, a trip mechanism, a vent channel, and a chamber. The trip mechanism is positioned within the housing can causes a movable contact to separate from a second contact in response to detection by the circuit breaker assembly of an electrical fault. The vent channel is formed in the housing and positioned to exhaust gas and debris produced as the movable contact separates from the second contact during the electrical fault to an aperture in the housing. The chamber has a chamber housing coupled to the housing adjacent the aperture such that the chamber receives the gas and debris exiting the aperture.

A circuit breaker includes a stationary contact, a plug-on half jaw, and a jaw spring. The plug-on half jaw is electrically coupled to the stationary contact and has a single terminal end for receiving a bus bar. The jaw spring is operatively coupled to the half jaw and has a bridge portion connecting two symmetrical spring legs.

A circuit breaker panelboard modular assembly employs a plurality of interdependent molded plastic and metal parts to multifunctionally adapt breakers of different ratings for electrical connection within the panelboard enclosure. Anti-turn connector connects the line strap terminal. Captive bolts or plug-in connections are employed to attach the breakers to the power bus. A novel concealed hinge construction is used to connect the panelboard door to the panelboard housing and the breakers are individually identified within the housing by extruded plastic circuit markers.
