Telescoping neurovascular catheter with enlargeable distal opening
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.
Electromagnetic induction welding of fluid distribution systems
Installation fittings for use with induction weldable pipe connectors for assembling multi-layer pipe fluid distribution systems. Induction welding pipe connectors including a major central pipe connector section and a minor lateral pipe connector section pair having reduced thickness relative to the major central pipe connector section. Induction welding pipe connectors with integral solder flow barrier for assembling fluid distribution systems. Electromagnetic induction coil reverse action pliers for use with induction weldable pipe connectors for assembling fluid distribution systems.
LIQUID STORAGE BOTTLE AND METHOD OF MANUFACTURING THE SAME
A liquid storage bottle includes a bottle body having a resin-made first cylindrical part at one end, the first cylindrical part having an opening at its front end, and a tubular nozzle for pouring out the liquid contained in the inside of the bottle body by way of the opening, the tubular nozzle having a resin-made second cylindrical part bonded to the bottle body. The inner peripheral surface of the second cylindrical part is welded to the outer peripheral surface of the first cylindrical part. The outer peripheral surface of the first cylindrical part is provided with an annular groove extending in the circumferential direction and the annular groove is made to contain a part of the resin that is molten during the bonding operation.
Double shear bonded joint and method for making same
Channel joints (1) can permit bonding a tube or tubular member (30) to an end fitting (20) in double shear. The channel joint may include a receiving channel (25) in the end fitting (20) that is complementary in shape to the tube, tubular member, or other hollow member (30) that is to be fitted and bonded with the end fitting. The use of a channel joint allows for simplified assembly because the receiving channel acts as a reservoir for the bonding agent or adhesive (50). Upon insertion of the tube, tubular member, or other hollow member into the adhesive-loaded receiving channel, the adhesive will backflow to fill the voids in the joint and expel the excess adhesive.
Leak-proof connection fitting
An apparatus and process by which a leak-proof connection with a polymeric tube is described herein. Particular embodiments of the present invention include a leak-proof connection fitting inserted into a bore of a overmolded attachment piece wherein the overmolded attachment piece is overmolded onto the polymeric tube. The leak-proof connection fitting includes multiple surfaces in various configurations. The multiple surfaces include barb(s), raised surface(s), reduced surface(s), and channel(s). O-rings may be further added to the leak-proof connection fitting. In some embodiments, the overmolded attachment piece or the tube itself is secured to the fitting by shape memory.
DEVICE FOR CONNECTING A TUBULAR ELEMENT, A COMBINATION OF A DEVICE WITH A TUBULAR ELEMENT AND A BONDING COMPOUND, AS WELL AS A METHOD FOR CONNECTING THE DEVICE WITH A TUBULAR ELEMENT
A device for connecting a tubular element such as a hose or pipe to a part of a hydraulic or pneumatic system includes: a body having a connection end and a tubular element insertion end, the body having a cylindrical channel extending from the connection end to the tubular element insertion end, the connection end being connecting to the part of the hydraulic or pneumatic system, the cylindrical channel including a first part and a second part, the first part being arranged in the tubular element insertion end and the second part being arranged in the connection end. The tubular element insertion end includes at a middle section a recess extending radially from the first part of the cylindrical channel, along an entire circumference, the recess bordering the second part of the cylindrical channel. The tubular element insertion end includes at least one bore.
PROCESS FOR JOINING OVERLAPPING THERMOPLASTIC MEMBRANE COMPONENTS
A method of joining overlapping thermoplastic membrane components in which a first thermoplastic membrane component and a second thermoplastic membrane component are positioned in overlapping relationship between a pair of complementary molding surfaces, with at least one of the complementary molding surfaces being defined by an electrically conductive metal susceptor. Heat is generated in the metal susceptor and transferred by thermal conduction from the metal susceptor to overlapping portions of the first and second thermoplastic membrane components to locally melt and coalesce at least a portion of the thermoplastic material of the first thermoplastic membrane component and at least a portion of the thermoplastic material of the second thermoplastic membrane component. The molten thermoplastic material of the first and second thermoplastic membrane components forms a zone of coalesced thermoplastic material that, upon cooling, forms a solid weld joint that fusion welds the first and second thermoplastic membrane components together.
Plug for an undersea cable
A plug for joining a polyethylene (PE) jacketed cable to a PE tube is provided. The plug includes first and second heating wires and a PE body. The PE body includes a first section and a second section. The first section is insertible into the PE tube and includes a first surface to engage with the PE tube. The first heating wires are embeddable in the first surface. The second section is within the first section and the PE jacketed cable is insertible into the second section. The second section includes a second surface to engage with the PE jacketed cable. The second heating wires are embeddable in the second section.
HIGH TEMPERATURE COMPOSITE SEAL
A method of sealing a first component to a second component comprising the steps of locating at least one fiber reinforced polyimide resin layer against a first sealing surface on a first component and against a second sealing surface on a second component. At least one fiber reinforced polyimide resin layer is compressed against the first sealing surface and the second sealing surface prior to curing at least one fiber reinforced polyimide resin layer. At least one fiber reinforced polyimide resin layer is heated to promote flow and conformation to the first sealing surface and the second sealing surface. At least one fiber reinforced polyimide resin layer is cured to provide a fluid tight seal between the first component and the second component.
Method of pulsatile neurovascular aspiration with telescoping catheter
A method of aspirating a vascular occlusion from a remote site is provided. The method includes the steps of advancing a first elongate tubular body through a vascular access site and into a body vessel, advancing a second tubular body distally to extend beyond the first elongate tubular body to reach the remote site, and aspirating thrombus from the site into the lumen by applying pulsatile vacuum to the first elongate tubular body. The second tubular body has a lumen and a length that is shorter than the first elongate tubular body. The pulsatile application of vacuum may cause the distal tip of the second tubular body to open and close like a jaw, which facilitates reshaping the thrombus or biting or nibbling the thrombus material into strands or pieces to facilitate proximal withdrawal under negative pressure through the lumen of the second tubular body.
