Patent number: 6718100Abstract: A flexible fire resistant innerduct structure is configured to contain a cable within a conduit. The innerduct structure includes a pair of adjacent strip-shaped layers of flexible material that are joined along their longitudinal edges to define a channel through which the cable can extend longitudinally through the innerduct structure between the layers. The adjacent layers have differing widths between their longitudinal edges, whereby the wider layer bulges away from the narrower layer to impart an open configuration to the channel. Other features of the innerduct structure relate to the material of which it is formed. Such features includes the structure of the material, such as a woven structure, and further include properties such as melting point, tensile strength, fire resistance, elongation, coefficient of friction, crimp resistance and compression recovery.Type: GrantFiled: March 28, 2002Date of Patent: April 6, 2004Assignee: Milliken & CompanyInventor: David Drew Morris

Patent number: 6702517Abstract: The present invention includes a pipe assembly for collecting water runoff. The pipe assembly includes a plurality of elongated primary pipes disposed in adjacent contact along their lengths. Each pair of adjacent elongated primary pipes define upper and lower elongated voids between adjacent pipe haunches and upper and lower imaginary planes tangential thereto. An elongated secondary pipe is disposed in each void in tangential contact along its length with the two adjacent elongated primary pipes defining the void. A material transversely encompasses the plurality of elongated primary pipes and elongated secondary pipes. The pipe assembly may be used in a water storage system and methods for installing such a system. The pipe assembly may also be used in a method for collecting surface water. The pipe assembly may be used in a system for use in a water flow path.Type: GrantFiled: November 21, 2001Date of Patent: March 9, 2004Assignee: Advanced Drainage Systems, Inc.Inventor: James B. Goddard

Patent number: 6702782Abstract: This is a balloon catheter having at least two lumens. One of the lumens is a large working lumen. The balloon catheter is especially useful as a guide catheter and may be used in a variety of therapeutic and diagnostic procedures. In particular, it has value in treating neurovascular embolic strokes in combination with other devices which are delivered to the stroke site through that working lumen. The remainder of the lumens typically are used to inflate and to deflate the balloon. It is highly preferable that the balloon or inflatable member be situated in a recess in the outer wall of the inventive catheter. Additionally, the distal end of the catheter past the balloon is preferably tapered. The catheter has a very low profile as compared to other catheters of the neurovascular balloon catheter genre. It may include other features such as variable stiffness along the axis of the device and anti-kinking components. The balloon is preferably compliant in nature.Type: GrantFiled: June 26, 2001Date of Patent: March 9, 2004Assignee: Concentric Medical, Inc.Inventors: John Miller, Martin Dieck, Maria Aboytes, Ryan Pierce

Publication number: 20030116212Abstract: The present invention relates to a fluid conduit, and to a multi-conduit umbilical for use in the transportation of chemicals with small molecular size and shape e.g. methanol ethanol and other hydrocarbon fluids used in the oil industry. The conduit comprises a flexible fluid hose encapsulated by at least one metallized layer which is formed and arranged to minimise permeation of a fluid being transported in the fluid hose. In use in a multi-conduit umbilical the metallized layer minimises permeation into adjacent fluid hoses containing chemicals. The invention is characterized in that the fluid hose(s) have differing levels of encapsulation and thereby permeation, along a given length according to the operational requirements of the fluid conduit/umbilical. Typically such fluid conduits/umbilicals will have lengths in excess of 100 km.Type: ApplicationFiled: December 20, 2002Publication date: June 26, 2003Inventor: Fraser Hynd Thomson

Patent number: 6571794Abstract: A respirator hose for connection between a ventilator and a breathing appliance during respiratory therapy includes a tubular body defining a first lumen for conveying a breathing gas from the ventilator, and a helical reinforcement member with a hollow core coiled around the tubular body to define a second lumen for conveying a second fluid in support of the respiratory therapy. The helical reinforcement member has a configuration to resist kinking and crushing of the tubular body that would close-off flow of the breathing gas. A fitting at one end of the hose can be keyed to simplify connections between the lumens and fluid communication ports of the ventilator.Type: GrantFiled: October 19, 2000Date of Patent: June 3, 2003Assignee: Mallinckrodt, Inc.Inventor: Gary Hansen
