Methods for reducing distal embolization

InactiveUS7033344B2Reducing distal embolizationSufficient pressureBalloon catheterCannulasDistal embolizationLesion
A method for reducing distal embolization during insertion of devices to treat plaque, thrombi and other intravascular occlusions. Using a guide catheter, a guidewire is delivered to a site proximal to the lesion. An aspiration catheter is then introduced over the guidewire, and the two are moved together in a distal to proximal direction across the occlusion. The aspiration catheter is then moved in a proximal to distal direction while continuously aspirating, which prevents embolization of any particles which may be created during the crossing of the guidewire.

Automated warehousing and cargo loading system

A warehousing system for palletized cargo, and an automated loading / unloading system for use with the same. The warehousing system includes a feed conveyer and a plurality of storage racks. A traveling conveyor carries the cargo from the feed conveyor to the individual racks, and from the racks to a loading / unloading conveyor which carries the cargo to the loading / unloading docks. The traveling conveyor rides on a wheeled chassis that is guided between the receiving and discharge locations on tracks. The storage racks are stackable in tiers, and the traveling conveyor has a deck that raises and lowers to be level therewith. The automated loading / unloading dock includes a rigid, extensible plate having an upper surface for supporting a load of palletized cargo, with a drive mechanism being mounted to the inner end of the plate to translate it in and out of the transport vehicle. The plate carries a load of palletized cargo into or out of the transport vehicle en masse. For loading, restraining doors hold the loaded cargo within the interior of the vehicle as the extensible dock is withdrawn. When unloading, a paddle is deployed above the upper surface of the lock member and is translated towards its inner end so as to push the cargo onto the loading / unloading conveyor.

Nano-Titanium For Making Medical Implantable Hermetic Feedthrough Assemblies

Ferrules made of nano-titanium for incorporation into feedthrough filter capacitor assemblies are described. The feedthrough filter capacitor assemblies are particularly useful for incorporation into implantable medical devices such as cardiac pacemakers, cardioverter defibrillators, and the like, to decouple and shield internal electronic components of the medical device from undesirable electromagnetic interference (EMI) signals. Nano-titanium experiences significantly less grain growth after high temperature brazing in comparison to commercially pure (CP) titanium and the titanium alloy Ti-6Al-4V. For that reason, nano-titanium is an ideal material for use in implantable medical applications where high strength, structural integrity even after heating and corrosion resistance are desired.

Coaxial Cable Connector with RFI Sealing

A coaxial cable connector and method that will direct the electromagnetic field carrying the electrical signal in a coaxial cable to the inner surface of a conductive layer of the foil of the cable, as opposed to the outer surface. With the electrical signals traveling on the inner surface of the foil conductive layer, the foil conductive layer serves as a contiguous gap-free shield to prevent the ingress and / or egress of RFI.

Fire-barriers for straight-line and intersecting expansion-spaces having male and female coupling-ends

Fire-barriers systems, including pre-assembled intersecting and straight-line fire-barriers having either all male-, all female-, or both types of coupling ends eliminate on-site cutting and construction of barriers required for intersection-spaces and provide easy, rapid, and safe one-step, drop-in installation and coupling. All male / female ended fire-barriers are constructed as single-piece units. All adjacent laid-flat layers are continuously connected having no gaps or folds. Straight-line and L-shaped barriers are certified according to the criteria mandated by both the ASTM E 1399-97 (Reapproved 2005), Standard Test Method for Cyclic Movement and Measuring the Minimum and Maximum Joint Widths of Architectural Joint Systems and the UL 2079 Fire Resistance of Building Joint Systems Test for air leakage (Revised and relocated as 1.14 Mar. 10, 2006).

A screening method can be used to determine whether a subject is a suitable candidate for interventional therapy. The method can be used to determine the likelihood the subject will receive a therapeutic effect from denervation therapy. The determination is based, at least in part, on lung information obtained by performing lung function tests with and without treating the subject's lungs with a test agent. Based on the response to a test agent, the subject's response to a therapy is predicted.

Variable-rate transport fees based on hazardous travel conditions

A system and method are responsive to actual or anticipated weather changes that are likely to have an adverse effect on roadway driving conditions in a given vehicle use area. Based on the anticipated severity of the weather condition, transport-related road and / or parking tolls and fees are increased in order to discourage unnecessary vehicle travel. Using a communication system such as a transponder network, changes in the tolls and fees can be transmitted to toll collection agencies, public parking facilities and other governmental and private enterprises responsible for the collection of vehicle transport fees. Rate change information and details of weather changes can also be transmitted to vehicles likely to be affected by the adverse condition and the consequent change in these fees.

Functionally graded coatings for lead wires in medical implantable hermetic feedthrough assemblies

A feedthrough filter capacitor assembly is described. The feedthrough filter capacitor assembly comprises an outer ferrule hermetically sealed to an insulator of a dielectric material seated within the ferrule. The insulative material is also hermetically sealed to at least one lead wire. Instead of being made of platinum or platinum / iridium, the lead wire comprises a core of a non-noble metal supporting a functionally graded coating. The metal core has an inner layer of the same the non-noble metal of the core and an outer layer of a noble metal. A gradient transition zone exists between the non-noble metal and the outer noble metal. Consequently, lead wires having all the beneficial attributes of platinum and platinum / iridium wire can be built into hermetic feedthroughs, but at a significantly reduced cost. In a preferred form, a filter capacitor is mounted on the insulator and electrically connected to the lead wires and to the ferrule to prevent unwanted EMI signals from traveling along the wires and entering the interior of the medical device.

Machine start controlling apparatus

An immobilizer ECU (20) compares an internally stored reference code with a key code transmitted from a key (10). An engine ECU (24) transmits a rolling code A when an engine speed reaches 500 rpm. The immobilizer ECU (20) transmits a rolling code B when the codes coincide with each other. The engine ECU (24) will stop an engine if it cannot receive the rolling code B within a prescribed period of time. Further, there is provided a counter CIMMOF which is incremented at the beginning of such a process. The counter CIMMOF is reset only when the process is normally completed. If an ignition is turned off prior to transmission and reception of the rolling codes, the counter CIMMOF will be counted up. According to a value of the counter CIMMOF, a period of waiting for the rolling code B is gradually shortened. Further, when the process is completed or a backup power supply to a backup memory (24d) is cut off, a time to transmit and receive the rolling codes is advanced. Thus, the situation where the engine will be able to start due to disconnection of a communication line or the like is prevented.
