A heat curable, circular knitted fabric includes reinforcing and meltable resin fibers that can be cured to form a more rigid material form. In one embodiment, the fabric includes a core spun yarn, wherein the core may be made from glass, carbon, basalt, aramid or metal. The wrap surrounding the core may include resin type fibers such as Poly(p-phenylene sulfide) PPS, Polyetherimide (PEI), Polyether ether ketone (PEEK), Polysulfone (PES), Polyphthalamide (PPA), nylon, polyester, or polypropylene.

A catheter for delivering fluids includes a hollow tube having a proximal section, a distal section, and an elongated lumen that extends through the proximal and distal sections of the hollow tube. One or more fluid openings are formed in the distal section of the hollow tube, which are in fluid communication with the elongated lumen of the hollow tube. A visible marker collar is secured to an outer surface of the hollow tube and is located at a junction of the proximal and distal sections of the hollow tube. A visible marker filament is disposed within the elongated lumen of the hollow tube and extends between the junction of the proximal and distal sections of the hollow tube and a distal end of the hollow tube. The visible markers are used to identify a soaker region of the catheter used to infuse fluids or drain fluids from a patient.

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 irrigation sleeve, for use with a surgical system that comprises an irrigation source and a surgical tool having a tube to support a cutting accessory having a head, in turn comprises a body extending between proximal and distal ends. A first lumen formed in the body receives the tube. The head is adjacent the distal end. A second lumen formed in the body is spaced from the first lumen and comprises proximal and distal regions thereof. The proximal region of the second lumen extends from an inlet for fluid communication with the source, to a transition. The distal region of the second lumen is spaced out of fluid communication with the first lumen and extends from the transition to an outlet to direct fluid adjacent to the head.

This invention encompasses a system and a method used in the petrochemical and mechanical engineering area, more specifically in the area of protecting pipes or similarly shaped objects against external or internal damage or wear, which comprises a protective system for the ends and the inside of coated pipes, using the coating itself and other additional devices. The system is comprised of a cup (1), spacer (2), coating (3), external ring (4), and cap (5) used in the production line of the pipe-coating process, using the external coating itself, preventing corrosion and mechanical damage at the ends/bevel, in the sandblasted area of the collar and internal surface, from storage and transport to the location where it will be used, and welding in the field or on the vessel.

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 tie layer, applying a helical coil to the outside of the tie layer, positioning a plurality of tubular segments, heating the tubular segments to form the high flexibility distal zone on the neurovascular catheter; and removing the mandrel.
