    摘要： An access device adapted for use in a body conduit is provided comprising an outer tube having a proximal end and a distal end, an inner tube disposed coaxially with the outer tube having a proximal end and a distal end, and an expandable portion having a first end coupled to the distal end of the outer tube and a second end coupled to the distal end of the inner tube. The outer tube and the inner tube are movable relative to each other to transform the expandable portion between a low-profile state and a high-profile state, and at least one of the outer and inner tubes comprises a wire-reinforced tube or is formed from a plurality of individual, discrete, generally ring-shaped elements arranged in series and fused or bonded together to form a continuous tubular structure. The access device may further comprise an actuator coupled to one of the outer and inner tubes and being movable relative to the other of the outer and inner tubes to transform the expandable portion between the low- and high-profile states. The expandable portion may be formed with a braid material and has the shape of a cone. The ring-shaped elements may be formed of a thermoplastic or a thermoset material, and they may include at least one of plastic rings, metallic rings, un-reinforced plastic rings and metal reinforced plastic rings assembled along the length of at least one of the tubes to provide variable flexibility and kink-resistance. The wire-reinforced tube is formed by coating a wire with a plastic material, wrapping the coated wire around a mandrel forming a plurality of windings, and heating the wound coated wire until the plastic material melts and bonds the windings forming the wire-reinforced tube.

    摘要： A drainage catheter is adapted to drain fluid from the body cavity through a body conduit and includes an elongate tube and a retention member disposed at the distal end of the elongate tube. The retention member is adapted for movement between a low-profile state facilitating insertion of the catheter and a high-profile state facilitating retention of the catheter in its operative position. A woven mesh forms at least a portion of one of the tube and the retention member. The woven mesh can be formed of filaments heat-settable so that the catheter automatically moves to the high-profile state. Insertion of the catheter can be facilitated using a stylet which can be removed after insertion to permit the catheter to automatically return to its high-profile state.

    摘要： Rolls for generally conveying sheets, such as of steel or glass over a roller typically have a steel mandrel and fiber-containing roll cover, with the fiber roll cover pressed between end plates. In a roll end assembly including the end plates there is now provided an axial shaft beyond the end plate. The shaft incorporates a roll compression means. The compression means includes a compression element which element engages the end plate. Pressure from the compression means, which may be exerted from beyond the shaft, can thereby be transmitted to the fiber roll.

    摘要： A fluid controlled device is adapted for disposition in a body conduit where it controls the flow of body fluids within the conduit. A sleeve is provided with a wall of separation having a first surface which defines a flow passage facilitating the flow of body fluids, and a second surface which defines an exclusion chamber sealed from the flow passage. Various dilators have properties for moving the seal between a low-profile state facilitating insertion of the device, any high-profile state defining the flow passage and exclusion chamber. The dilator may be skeletal, inflatable, and/or porous. An associated method includes the step of dilating a dilation assembly to move a wall from a low profile, insertible state, to a high-profile wherein the wall defines a flow passage and an exclusion cavity.

    摘要： The invention is directed to a trocar seal adapted to form a seal around a surgical instrument, the trocar seal comprising a housing having an axis extending between a proximal end and a distal end and forming a working channel sized and configured to receive the surgical instrument; an elastomeric septum seal having a proximal face and a distal face, the septum seal being disposed in the housing and extending transverse to the axis of the housing across the working channel; portions of the septum seal defining a hole having a diameter less than or equal to the diameter of the surgical instrument so that during insertion of the instrument along the working channel the septum seal forms a seal with the instrument; and at least one structure formed integrally with or proximate to the septum seal to prevent inversion of the septum seal upon withdrawal of the surgical instrument. The septum seal or the housing may further comprise a sidewall to include the structure extending from the sidewall to the distal face of the seal to tether the seal distally. The structure may be integrally formed with the proximal face of the septum seal to reinforce the seal, or the structure may be integrally formed with the distal face of the septum seal to tether the seal distally. The structure may be an annular reinforcement or rib, and is formed so as to allow side-to-side movement or floatation of the seal. The trocar seal may further comprise a plurality of radially extending ribs formed on the proximal or distal face of the septum seal to reinforce the seal. The trocar seal may further comprise a tensile element formed on the distal face of the septum seal.

    摘要： A surgical clip having a sliding state and a crimped state is adapted for use in a surgical procedure initially to slide along suture ends to an operative position and ultimately to crimp the suture ends at the operative position. a sub straight, bendable between the sliding state and the crimped state carries at least one coating having either lubricious or traction enhancing properties. A second coating can be added to form a coating laminate with the outer coating having lubricious properties facilitating the sliding state and the inner coating having traction enhancing properties facilitating thee crimped state.
