A neurovascular catheter is provided, such as for distal neurovascular access or aspiration. The catheter includes an elongate flexible tubular body, having a proximal end, a distal end and a side wall defining a central lumen. A distal zone of the tubular body includes a tubular inner liner, a tie layer separated from the lumen by the inner liner, a helical coil surrounding the tie layer, an outer jacket surrounding the helical coil, and an opening at the distal end. Adjacent windings of the helical coil are spaced progressively further apart in the distal direction. The opening at the distal end of the tubular body is enlargeable from a first inside diameter for transluminal navigation to a second, larger inside diameter to facilitate aspiration of thrombus into the lumen.

An enhanced flexibility neurovascular catheter is provided, such as for distal neurovascular access or aspiration. The catheter includes an elongate flexible body, having a proximal end, a distal end and a side wall defining a central lumen. A distal zone of the side wall includes an outer jacket surrounding a helical coil, and the outer jacket is formed from a plurality of tubular segments positioned coaxially about the coil. A proximal one of the tubular segments has a durometer of at least about 60D, and a distal one of the tubular segments has a durometer of no more than about 35D. An axially extending filament within the side wall extends at least about the most distal 10 cm of the length of the catheter. The axially extending filament serves as a tension support and resists elongation of the catheter wall under tension, such as when the catheter is being proximally retracted through tortuous vasculature.

A telescoping catheter is provided such as for distal neurovascular aspiration or access. The catheter includes an elongate, flexible tubular body, having a proximal section with at least one lumen and a distal section which is axially movably positioned within the lumen. A control is provided for advancing the distal section from a first, proximally retracted position within the proximal section to a second extended position, extending distally beyond the proximal section. The distal end of at least one of the proximal and distal sections may be provided with at least one active feature, such as at least one movable jaw or rotatable agitator, to assist in the capture of vascular obstruction. The jaw may be operable in response to application of pulsatile negative pressure through the catheter.

A method of making a high flexibility distal zone on a neurovascular catheter is provided. The method includes the steps of dip coating a removable mandrel to form a tubular inner layer on the mandrel, coating the tubular inner layer with a soft tie layer, applying a helical coil to the outside of the tie layer, positioning a plurality of tubular segments on the helical coil, heating the tubular segments to form the high flexibility distal zone on the neurovascular catheter; and removing the mandrel. The plurality of segments have durometers that decrease in a distal direction. The flexural load profile of the catheter as a function of catheter length is configured to provide enhanced distal flexibility while maintaining high backup support.

A method of making a cabinet for refrigerators and the like. The method includes forming a liner and a wrapper. The method further includes providing a vacuum insulated core that includes a filler material disposed inside a substantially impermeable envelope that is evacuated to form a vacuum inside of the envelope. The vacuum insulated core includes a first wall and a second wall extending transversely relative to the first wall. The core is adhesively secured to the wrapper, and the liner is adhesively secured to the core. The wrapper and the liner are sealed together at the peripheries thereof.

Protective coverings herein have a coated woven material with a first edge parallel with a warp direction and a second edge opposite the first edge, and have a first edge band proximate the first edge and a second edge band proximate the second edge. The coated woven material has a woven scrim made of a plurality of weft tapes and a plurality of warp tapes, but the warp tapes positioned in the first and second edge bands are high-shrinkage warp tapes and the warp tapes positioned in between the first and second edge bands have a shrinkage that is less than a shrinkage of the high-shrinkage warp tapes, and has a coating on at least one major surface of the woven scrim. The plurality of high-shrinkage warp tapes shrink upon application of heat. Methods of covering a load, such as stacked lumber, with the protective covering are also disclosed.

A kit for encapsulating a length of pipe features first and second foam sections cooperatively shaped to form a cavity with open ends in a working configuration of the foam sections for receiving the length of pipe therein. A low density foam, which is lower in density than the material of the foam sections, fills an unoccupied space in the cavity so as to provide cushioning for the length of pipe such that movement of the length of pipe within the cavity is permitted and stress on the length of pipe is reduced. The foam sections may be reinforced with reinforcing membranes carried in a main body of the respective foam section. The reinforcing membranes may act to hold the foam material of the respective section together and to prevent puncture along a full thickness of the foam sections from abrasive debris in the ground.

A method of coating a field joint of a pipeline places at least one body having a thermoplastics material around the field joint. The body is heated in a mould cavity around the field joint to effect thermal expansion of the thermoplastics material. Thermal expansion of the body in the mould cavity is constrained to apply elevated pressure between the body and pipe sections joined at the field joint. The elevated pressure improves bonding and fusing between the body, which forms a field joint coating, and the parent coatings and the exposed pipe sections of the pipe joints. The body need not be fully molten, which reduces the mould residence time including in-mould heating and cooling phases.

The present techniques are directed to systems and methods for forming a pipe-conforming structure. The pipe-conforming structure includes a polymer material and one or more optic fibers embedded within the polymer material. The polymer material is formed into a structure that is conformed to the shape of a pipe. A method includes forming a polymer material into a structure including an edge region and a center region. The center region has a greater thickness than the edge region. The method includes inserting one or more optic fibers into the polymer material.
