    • The invention is directed to a trocar adapted to form a seal around a surgical instrument, the trocar comprising a cannula having an axis extending between a proximal end and a distal end; a housing having a proximal wall and forming with the cannula a working channel sized and configured to receive the instrument; a septum seal disposed in the housing and extending transverse to the axis of the cannula across the working channel, the septum seal having a normal state when the instrument is absent from the working channel and a stretched state when the instrument is being withdrawn from the working channel; portions of the proximal wall of the housing defining an orifice sized and configured to receive the instrument into the working channel; and an elastomeric ring-shaped projection extending axially distally between the proximal wail and the septum seal, the ring-shaped projection having an axial length adapted to deform to prevent inversion and binding of the septum seal and the orifice upon withdrawal of the surgical instrument. In particular, the septum seal is prevented from reaching the orifice in the proximal wall of the housing when the instrument is withdrawn. The projection may be bonded, insert-molded, or compressively fitted to the proximal wall of the housing. The projection may be formed of an elastomeric material such as natural or synthetic rubber. The projection may further comprise a plurality of portions or fingers extending axially distally from the proximal wall, each of the extending portions or fingers may further include a living hinge. In another aspect, the ring-shaped projection may be formed on the surface of the septum seal instead of the proximal wall of the housing. That is, the ring-shaped projection may be formed to extend axially proximally from the surface of the septum seal toward the proximal wall of the housing.

    • 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.

The ring-shaped elements may include a combination of flexible and rigid ring-shaped elements assembled along different portions or sections of the tubular structure. The ring-shaped elements may be metallic and may be bonded with a resilient, flexible elastomeric adhesive, wherein the ring-shaped elements may have different lengths and may be fused closer or further apart to one another depending on the characteristics of a portion or section of the tubing. In another aspect of the invention, the medical tubing may further comprise a secondary lumen and a pull wire to control the tubular structure. The ring-shaped elements may be truncated to provide a bending bias. In another aspect of the invention, the ring-shaped elements may vary in diameter and/or composition in different portions or sections of the tubular structure. In yet another aspect of the invention, some of the ring-shaped elements may be radiopaque, or the ring-shaped elements may comprise of different colors to operate as indicators along the tubular structure.
