    摘要： A multi-seal trocar system includes a plurality of co-axial sealing elements adapted for forming a seal with either a large or small instrument. Small and large sealing elements are disposed in an in-line arrangement such that a-single port is provided for instrument insertion. A zero seal is disposed distally of the sealing elements to seal a working channel of the system and to prevent backflow when no instruments are inserted. The small sealing element is configured such that insertion of a large instrument automatically moves the small sealing element out of its path, thereby avoiding contact with the large instrument.

    摘要： A steerable kink resistant access device is provided having an elongated body and a steerable portion; methods for manufacturing the kink resistant device are also provided. 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： 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 100 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。 悬挂阀可以在细长结构的近端和远端两侧浮动，以进一步减少隔膜阀100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。
