Abstract: In one aspect there is provided a gas flare comprising a hollow cylindrical member having a bottom end, a top end, a discharge end at said top end, and defining an interior volume having a mixing region. The gas flare further comprises a gas inlet to receive waste fluids, an air inlet to receive and direct air into the interior volume, and an internal riser having an outlet. The mixing region is located above the air inlet and below the discharge end. The internal riser fluidly and sealably connects to the gas inlet and directs all waste fluids from the gas inlet, out through the outlet, into the mixing region.

Abstract: A composite intraluminal prosthesis which is preferably used as a vascular prosthesis includes a layer of ePTFE and a layer of textile material which are secured together by an elastomeric bonding agent. The ePTFE layer includes a porous microstructure defined by nodes interconnected by fibrils. The adhesive bonding agent is preferably applied in solution so that the bonding agent enters the pores of the microstructure of the ePTFE. This helps secure the textile layer to the ePTFE layer.

Abstract: A multiple braid exterior tube having a composite structure which includes an inner tubular layer, reinforcing layers and a polymer matrix layer. The exterior tube is formed with polymeric materials and metallic reinforcing braiding configured to provide greater tensile strength and stiffness. The exterior tube is used for a variety of medical devices such as a sheath component for intravascular devices and catheters.

Abstract: A stent may be formed of at least one structural material having a pattern including at least one serpentine structure, which extends about the longitudinal axis of the stent. The structure is formed of a plurality of struts. Adjacent struts are interconnected by end portions having inner turns and outer turns. At least some of the end portions are elongated and other end portions are non-elongated and have a predetermined length. At least one of said elongated end portions is configured to serve as a fiducial marker.

Abstract: A stent comprises a plurality of connected serpentine circumferential bands. Adjacent serpentine circumferential bands are connected via a plurality of longitudinal connectors extending between peaks on one serpentine circumferential band and troughs on the serpentine circumferential band adjacent thereto. The struts of the serpentine bands are arranged such that on expansion of the stent, peaks and troughs which are substantially circumferentially aligned with one another, but not connected with one another, on adjacent serpentine circumferential bands are circumferentially displaced from one another.

Abstract: A stent may be formed of at least one structural material having a pattern including at least one serpentine structure which extends about the longitudinal axis of the stent. The structure is formed of a plurality of struts. Adjacent struts are interconnected by end portions having inner turns and outer turns. At least some of the end portions are elongated and other end portions are non-elongated and have a predetermined length. The inner turns of the elongated end portions are substantially unaligned longitudinally with the inner turns of the non-elongated end portions. At least one of said elongated end portions is configured to serve as a fiducial marker.

Abstract: A multi-section filamentary stent comprises a braided section, which is a cylindrical mesh of a first set of filaments, connected to at least one wound section comprising a second set of one or more filaments having a repeating configuration with a bent portion. The two sections are preferably connected by at least one continuous filament extending into both sections. The two sections may be connected by a weld, a suture, a common graft, an overlapping portion of the two sections, or one or more filaments of one section looping through portions of the other section. The stent may comprise a first section, having a braided first stent architecture with a first flexibility and a first radial force, and a second section, having a non-braided second stent architecture with a second flexibility less than the first flexibility and a second radial force greater than the first radial force, in which at least one continuous filament is integral to both the first and second sections.

Abstract: In at least one embodiment, a stent comprises a plurality of serpentine bands and a plurality of connector struts. Adjacent serpentine bands are connected by at least one connector strut. Each serpentine band comprises a plurality of alternating straight band struts and turns. Each connector strut is connected at one end to a turn of one serpentine band and connected at the other end to a turn of another serpentine band. The turns of a serpentine band comprise connected turns that connect to a connector strut and unconnected turns that do not connect to a connector strut. At least one of the serpentine bands comprises a repeating pattern of three band struts and then five band struts extending between connected turns as the serpentine band is traversed.

Abstract: The invention relates to a stent-graft with a bioabsorbable structure and a permanent graft for luminal support and treatment of arterial fistulas, occlusive disease, and aneurysms. The bioabsorbable structure is formed from braided filaments of materials such as PLA, PLLA, PDLA, and PGA and the graft is formed from materials such as PET, ePTFE, PCU or PU.

Abstract: An introducer deploys an endoluminal device in a distal location from a proximal location. The introducer comprises a retrograde portion, an anterograde portion axially moveable relative to the retrograde portion, a shaft having a distal tip and an anterograde sheath attached to the distal tip, and anchoring means in at least one of the retrograde portion or the anterograde portion for anchoring the device during deployment from its proximal end to its distal end. An inner sheath may be mounted concentrically over the shaft with the endoluminal device mounted concentrically over the inner sheath. The anchoring device may comprise an inflatable balloon mounted radially inside the retrograde portion, a tether, or an extended portion of the endoluminal device confined by a notch in the interface of two sheaths in the retrograde portion of the introducer, or may comprise a holder in the anterograde portion.

Abstract: A venous valve with a tubular frame that includes an outer surface and an inner surface opposite the outer surface and defining a lumen, and a cover over at least the outer surface of the tubular frame, where the cover includes surfaces defining a reversibly sealable opening for unidirectional flow of a liquid through the lumen. A system with the venous valve and a catheter including a proximal end and a distal end, the venous valve located between the proximal end and distal end of the catheter. A method including forming the venous valve and reversibly joining the venous valve and a catheter. A method including positioning at least part of the catheter including the venous valve at a predetermined location and deploying the venous valve from the catheter at the predetermined location.
