摘要： A valve assembly includes a valve collar, a rotatable valve control member, and a flexible valve member disposed therebetween. The valve control member and the valve collar are aligned to define an elongated passageway, and the flexible valve member is disposed along the passageway. The valve collar is structured such that at least a portion thereof is capable of radial flexure upon engagement with a mechanism on the rotatable valve control member. One end of the valve member is secured to the valve collar, and the other end is secured to the rotatable valve control member. Upon rotation of the rotatable valve control member relative to the valve collar, the mechanism of the rotatable valve control member engages the valve collar portion in a manner such that the valve collar portion flexes in a radial direction and a tactile sensation is produced thereby, and the flexible valve member constricts from an open position to a position wherein the flexible valve member opening is at least partially closed to passage of fluid therethrough.

摘要： An endoluminal prosthesis having a tubular graft comprising a first biocompatible material having a first weave density comprising yarns aligned in a first direction interwoven with yarns aligned in a second direction, and a second biocompatible material having a second weave density less than the first weave density comprising yarns aligned in a first direction interwoven with yarns aligned in a second direction, the second biocompatible material spirally positioned throughout the entire length of the tubular graft around a central axis with respect to the first biocompatible material. An elongate member is attached along the length of the tubular graft. The tubular graft includes first regions comprising the first biocompatible material and second regions containing the second biocompatible material. The elongate member is attached to the first regions of the tubular graft.

摘要： An endoluminal prosthesis may include a tubular graft extending in a longitudinal direction, where the graft has an inner surface forming a lumen extending a length of the graft. An elongate member may be attached to the graft in a circumferentially and longitudinally extending manner such that the elongate member forms a series of longitudinally spaced apart turns, each turn extending substantially around a circumference of the graft. The elongate member may torsion the graft in at least the circumferential direction and cause the graft to form circumferentially and longitudinally extending folds in the portions of the graft disposed between longitudinally adjacent turns of the elongate member.

摘要： An oroesophageal introducer assembly for atraumatically introducing a relatively large instrument such as an echotransducer positioned on the distal end of a gastroscope for performing an echocardiographic procedure. The introducer assembly includes an outer sheath having a tapered distal end and a passageway extending therethrough for passing the large instrument therethrough. The assembly further includes a dilator extending from the tapered distal end of the outer sheath for atraumatically dilating the esophagus during introduction. The assembly further includes an introducer guide for initial oral introduction into the esophagus and stomach of the patient. The outer sheath and dilator are interconnected at the proximal ends thereof for extending the tapered distal end of the dilator from the tapered distal end of the outer sheath. The interconnected outer sheath and dilator are then introduced atraumatically into the esophagus over the introducer guide. When positioned in the esophagus, the dilator is disconnected from the outer sheath, and the dilator and introducer guide are removed from the outer sheath and patient. A relatively large diagnostic instrument is introduced through the outer sheath for performing various diagnostic or treatment procedures. The inner and outer sheaths are comprised of a flexible material, with the outer diameter of the inner sheath being substantially less than the inner diameter of the outer sheath to maintain flexibility of the assembly during introduction into the esophagus.
摘要翻译： 一种食道导入器组件，用于无菌地引入位于胃镜远端的相对较大的器械，例如echotransducer，用于执行超声心动图。 导引器组件包括外护套，其具有锥形远端和延伸穿过其中的通道，用于使大器械通过其中。 组件还包括从外护套的锥形远端延伸的扩张器，用于在引入期间无损伤地扩张食道。 组件还包括用于初始口服引入患者的食道和胃的导引器引导件。 外护套和扩张器在其近端处互连，用于使扩张器的锥形远端从外护套的锥形远端延伸。 然后将相互连接的外护套和扩张器无创地引入到导引器引导件上的食道中。 当定位在食道中时，扩张器与外鞘分离，并且扩张器和引导器引导件从外护套和患者移除。 通过外鞘引入相对较大的诊断仪器，用于执行各种诊断或治疗程序。 内护套和外护套由柔性材料构成，内护套的外径基本上小于外护套的内径，以在引入食道期间保持组件的柔性。
