A catheter for mapping and / or ablating continuous linear or circumferential lesions at the intersection of a generally flat structure, such as the left atrium, and the ostium of generally cavernous regions of the heart, including pulmonary vein and the pulmonary venous antrum, comprises a catheter body with an intermediate section that is connected to a tip assembly by a highly flexible section. The intermediate section has at its distal end a preformed section, e.g., a curve, the intermediate section being deflectable in a direction opposite to the curve. The highly flexible section presets the tip assembly at an off-axis and / or off-plane angles from the preformed section. Accordingly, the preformed section is adapted to sit in the region and the preset angles of the ablation assembly enable contact with surrounding tissue. A high bending modulus enables the flexible section absorb displacement force applied to the ablation assembly, such as when the tip assembly encounters uneven tissue surface, without displacing the curve from the region. The tip assembly can be irrigated as enabled by a plurality of irrigation ports, a coil electrode, and a porous covering to disperse fluid over the outer surface of the tip assembly.

An improved modular heat exchanger suitable for automotive applications, and particularly radiators for heavy duty equipment, and methods for forming the modular heat exchanger. The modular heat exchanger construction incorporates a brazed core assembly composed of flat-type cooling tubes and sinusoidal centers. The ability to use a brazed core assembly within a modular heat exchanger construction promotes enhanced heat transfer efficiencies associated with the use of flat tubes and sinusoidal centers, as compared to mechanically-joined round tubes and fins. The required positional tolerances of the tubes for mating with the remainder of the heat exchanger are maintained within the brazed core assembly by eliminating core shrinkage attributable to the use of clad aluminum alloy components to construct the core assembly. In two embodiments, core shrinkage is physical suppressed through the use of an expandable brazing fixture or the inclusion of sub-headers in the brazed core assembly. In a third embodiment, a clad slurry containing a braze alloy is deposited prior to brazing on a core assembly composed of unclad tubes and centers.

A transuterine cannula through which an endoscope can be advanced into the peritoneal space to provide visualization of tissue cutting in the peritoneal space pursuant to a vaginal hysterectomy.

A modular heat exchanger suitable for automotive applications, and methods for forming the modular heat exchanger. The modular heat exchanger construction incorporates a monolithic brazed core assembly composed of flat-type cooling tubes and sinusoidal centers. The required positional tolerances of the tubes for mating with the remainder of the heat exchanger are maintained within the brazed core assembly by minimizing core shrinkage resulting from the brazing operation during which the tubes are brazed to the centers.

An inexpensive, endo-tracheal intubation device is disclosed. Methods of making and using the inexpensive, endo-tracheal intubation device are also disclosed.

A device for the non-destructive testing of parts of a turbomachine motor, including a longitudinal rod carrying at its distal end a longitudinal finger carrying a retractile or deployable flexible blade supporting an inspection probe, this blade being guided in axial translation on the finger between a retracted position in which it extends along the finger and an advanced or deployed position in which it extends in front of the finger.

A conical washer having a crush zone wherein the inner annular projection comprises a top and bottom elevation where the top elevation lies at an approximately 100 to 165 degree angle to the inner annular wall of the washer and the bottom elevation is substantially flush with the bottom surface of the washer. The inner annular projection forms a crush zone, which collapses and crushes when an attachment device passes through the washer and is tightened down by a user. The crush zone provides a tight engagement of fastener to the bearing surface, and one which eliminates looseness in the fastener upon thermal expansion of the metal of the elements.

The present invention is related to spacers that can create fluid flow space at a variety of structural interfaces, particularly in building construction. The spacers of the present invention include unique hinges that can physically couple one panel of the spacer to another panel of the spacer in a manner that substantially distortionally separates the two panels. Preferred embodiments include a folded hinge having at least two folds. The spacers of the present invention also include unique panel dimples that help control the rigidity of the panel. In preferred embodiments, elongated dimples are used to help control rigidity.

A curable aqueous binder composition comprising one or more amine reactant selected from the group consisting of: a protein, a peptide, an amino acid, an ammonium salt of a polycarboxylic acid, an ammonium salt of a (poly)hydroxy-(poly)carboxylic acid; one or more carbohydrate; and one or more emulsion polymer; and the use thereof as thermosetting binders. Also described are composite materials comprising the curable binder composition, and methods of application.

A polymer prosthesis with lumen and an axial length and having in a pre-delivery condition a plurality of relatively stiff stenting segments spaced from each other along the length of the prosthesis, the spaces between the relatively stiff stenting segments of a first polymer being bridged by relatively flexible linking segments of a second polymer, different from the first, the relatively stiff stenting segments and the relatively flexible linking segments being alternately arranged along the length of the prosthesis.

The present invention provides aqueous binder compositions that are free of nitrogen-containing Maillard reactants comprise a carbohydrate component of one or more mono- or di-saccharide and an oligosaccharide having at least three saccharide groups, a polymeric polyacid and a bleaching agent provide cured binders from carbohydrates that enable the provision of thermosets with low color or white color and acceptable physical properties.

A leather bicycle saddle includes a leather cover, an arc support supporting the leather cover and having a front end terminating in a head abutment portion and a rear end affixed to a rear bottom side of the leather cover, and an adjustment device including a screw bolt holder affixed to a front bottom side of the leather cover, an adjustment screw bolt abutted against the screw bolt holder. The adjustment seat includes a seat block defining a mounting slot and a screw hole, and a stop block. The stop block is engaged into the open end of the mounting slot and stopped at the head abutment portion of the arc support against the closed end of the mounting slot. The screw hole of the seat block receives the adjustment screw bolt.

In a coiled tubing assembly for use in a wellbore, the tubing assembly uses longitudinally spaced apart clamping members to clamp two or more coiled tubing members alongside one another. Each clamping member includes a clamping portion extending circumferentially about each coiled tubing member so as to be rotatable in relation thereto, and a connecting portion joined between the clamping portions. A longitudinal positioning element is fixed relative to one of the tubing members in association with each clamping member such that the clamping member remains pivotal relative to the positioning element and the tubing members upon which it is fixed. The longitudinal positioning element thus only restricts the respective clamping assembly in the longitudinal direction along the tubing members without restricting relative twisting between the tubing members.
