Elastomeric balloon support fabric

Balloon catheter covers are elastic fabric structures of interconnected yarns, the structure having a high degree of stretch and recovery in the circumferential direction with little change in dimension in the longitudinal direction during multiple pressurization cycles over full range of inflation and deflation of the balloon catheter. The covers have longitudinal yarns positioned at about zero degrees to the balloon axis and reversibly-stretchable, circumferential yarns positioned at a high angle Ø to the axis. A method for making the balloon catheter covers allowing nearly orthogonal placement of circumferential and longitudinal yarns involves triaxial braiding a minimum number of elastomeric braid yarns with multiple axial yarns to provide maximum convergence angle (approaching 90 degrees).

Bimodal pore size nonwoven web and wiper

The present invention provides a nonwoven web laminate having at least a bimodal pore size distribution. The laminate has a first layer with pores having a mean equivalent pore radius greater than about 100 μm and a second layer with pores having a mean equivalent pore radius less than about 100 μm. Generally, the first layer has a mean equivalent pore size radius in the range of about 1 μm to about 100 μm and the second layer has a mean equivalent pore size radius in the range of about 100 μm to about 1000 μm. The layer having an average pore size radius greater than 100 μm provides rapid fluid release from the laminate to facilitate cleaning by providing a cleaning solution to solubilize particles or viscous liquids on the surface. In addition, the large pore size allows particles and viscous liquids to be captured and trapped within the pores of the laminate, thereby effectively cleaning the surface to be cleaned. The layer with the small pore size provides a fluid reservoir function by absorbing fluid and holding the fluid in the laminate, or by holding a cleaning fluid to be released during a cleaning operation. The nonwoven web laminate of the present invention is an effective wiper.

The long, chopped fibers can be distributed continuously or only along portions of the width of the fabric. The disclosed methods of manufacturing a liner include alternative processes by which the liner can be made. The fabric is manufactured in the form of a continuous roll. One method involves winding the roll in a helical pattern about a fixed mandrel. Another method involves mounting several rolls circumferentially about a mandrel. The rolls are mounted so that strips of fabric from each roll overlap a portion of adjacent fabric strips to provide a continuous liner surface on the mandrel.

Multiple pig subsea pig launcher

The pig launcher is installed subsea by coupling it to a launcher manifold. The launcher manifold is installed substantially permanently subsea as a part of a pipeline. The pig launcher includes a dual bore collet connector for coupling to the launcher manifold, and a rotary storage magazine for storing the pigs. The launcher manifold can be manufactured, for example, as part of an inline lateral tie-in sled or as part of a pipeline end manifold (PLEM). A branch connection from the pipeline to the pig launcher is provided in the launcher manifold via a piggable Y connection to a dual bore collet connector male hub. The pig launcher is landed and latched to the launcher manifold to complete the pig launching system. A closure valve between the Y connection and the hub prevents a pressure loss when the pig launcher is not installed, and the closure valve is opened to permit passage of the pigs during launching. A throttle valve upstream of the Y connection allows the pipeline pressure to be dropped downstream so that a pig can be launched using upstream pressure. During launching, a kicker valve is opened to bypass the throttle valve and direct the higher upstream pressure through the secondary bore of the dual bore collet connector and into the rotary magazine.

Method for making a porous Polymeric material

Porous polymers having a plurality of openings or chambers that are highly convoluted, with each chamber being defined by multiple, thin, flat partitions are produced by a new gel enhanced phase separation technique. In a preferred embodiment, a second solvent is added to a polymer solution, the second solvent causing the solution to gel. The gel can then be shaped as needed. Subsequent solvent extraction leaves the porous polymeric body of defined shape. The porous polymers have utility as medical prostheses, the porosity permitting ingrowth of neighboring tissue. The present technique also enhances shape-making capability, for example, of bifurcated vascular grafts, which feature a common entrance region but two or more exit regions.
