    摘要： A steerable kink resistant access device is provided having an elongated body and a steerable portion. The access sheath has an outside diameter sufficiently small so that it may be inserted into a body cavity or conduit. The access sheath typically has two internal lumen, a first lumen sized and configured as an access to a surgical site and a second lumen sized and configured to contain a tensioning device that, when acted upon, will deflect the steerable portion. The tensioning device may be directly or remotely attached to an actuation device that operates to control the tensioning and loosening of the tensioning device.

    摘要： The invention primarily is directed to a medical tubing adapted for insertion into a body tissue or cavity and method of manufacturing different variations of the tubing along a length of the tubing. The tubing comprises a plurality of individual, discrete, generally ring-shaped elements arranged in series and fused or bonded together forming a continuous tubular structure. The ring-shaped elements may be formed of a thermoplastic or a thermoset material. The ring-shaped elements may include plastic rings, metallic rings, un-reinforced plastic rings and/or metal reinforced plastic rings assembled along the length of the tubular structure to provide variable flexibility and kink-resistance. The tubular structure may have a cross-section of any geometric shape and it may be bent, twisted or curved without kinking. The ring-shaped elements may have different flexural modulus. 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.

    摘要： A surgical access device, such as a trocar, includes a pendent valve having an elongate structure extending from a proximal end to a septum valve disposed at a distal end. In operation, the elongate structure follows the angle of the instrument to pre-position the septum valve into the path of the instrument where it is not significantly challenged during instrument insertion or manipulation. The pendant valve can be made to float at both the proximal end and the distal end of the elongate structure, to further reduce the vulnerability of the septum valve. Since the valve is less vulnerable to instrument insertion, it can be formed to minimize friction and maximize the functional range of the access device.

    摘要翻译： 手术进入装置，例如套管针，包括具有从近端延伸到设置在远端的隔膜阀的细长结构的侧悬阀。 在操作中，细长结构遵循仪器的角度，以将隔膜阀预先定位到仪器的路径中，在仪器插入或操纵期间，隔膜阀不会受到严重的挑战。 悬挂阀可以制成在细长结构的近端和远端两侧浮动，以进一步降低隔膜阀的脆弱性。 由于阀门不易受仪器插入的影响，因此可以形成最小化摩擦力并最大化进入设备的功能范围。

    摘要： The trocar system includes a cannula insertable through a body wall using an obturator having a distal tip. A traction tread disposed interiorly of the obturator inverts at the distal tip and extends proximally along the outer surface of the obturator or cannula. At the distal tip the tread can facilitate parting rather than cutting the tissue Along the outer surface, the tread can engage the tissue to pull it proximally along the advancing obturator. This produces counter forces which can result in a net proximal force facilitating distention of the abdominal wall and separation of the abdominal wall from internal organs The traction tread can be axially and/or radially continuous. An associated method of operation includes the steps of contacting the body wall with the traction tread at the distal tip, and engaging the body wall with the traction tread along wall portions facing the outer surface
