    摘要： An expandable medical sheath is configured to be introduced into a body in a first, low cross-sectional area configuration, and expanded to a second, enlarged cross-sectional configuration. The sheath is maintained in the first, low cross-sectional configuration by structures or elements within the sheath wall that maintain a collapsed shape. Upon expansion with a dilator, the sheath maintains a second, enlarged cross-sectional configuration by elements or structures within the sheath tubing wall that resist re-collapse. The sheath includes a nose cone or tapered fairing to deflect tissue from entering the collapsed distal end of the sheath during introduction. The fairing collapses following expansion and subsequent deflation of the dilator, thus allowing the tapered fairing to be withdrawn proximally through the central lumen of the sheath. In one application, the sheath is utilized to provide access for a diagnostic or therapeutic procedure such as percutaneous nephrostomy or urinary bladder access.

    摘要： An expandable sheath is insertable into a patient through an incision. Once inserted and advanced to the target surgical site, the sheath can be expanded to an enlarged diameter. The wall of the sheath is fabricated from a tubular structure comprising filamentous elements that extend axially and at least partially circumferentially along the length of the sheath. The tubular filamentous material is drawn or expanded axially to create the small diameter configuration that is inserted into the patient. A standoff attaches the distal end of the tubular filamentous material to the sheath hub by way of radially movable anchors. Additional filamentous tubular material extends out the proximal end of the hub. A compression mechanism forces the additional filamentous tubular material in the distal direction which causes axial compression and radial or diametric dilation of the working length of the sheath, that part of the sheath that extends beyond the proximal end of the hub. Radial dilation is accomplished with no substantial change in sheath working length.

    摘要： Disclosed is a hub for a transluminal sheath. The hub provides a handle for grasping the sheath, provides connections for fluid inlet and outlet lines, and provides for attaching mechanisms between the sheath and a dilator. The hub can be used on a non-radially expandable sheath, or it can be used on a sheath having a radially expandable configuration. In an exemplary application, the hub is fitted to a sheath, which provides access for a diagnostic or therapeutic procedure such as ureteroscopy or stone removal.

    摘要： Disclosed is an expandable percutaneous sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The sheath is configured for use in the upper gastrointestinal tract and has utility in the performance of procedures in the esophagus and stomach. The access route is through the anterior abdominal wall to the stomach. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement through the abdominal wall and into the stomach. The distal end of the sheath is subsequently expanded using a radial dilatation device. In an exemplary application, the sheath is utilized to provide access for a diagnostic or therapeutic procedure such as diagnosis and repair of gastro esophageal reflux disease. The sheath further can be secured within the gastrointestinal system and be used to draw the stomach wall against the abdominal wall.

    摘要： Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The sheath is configured for use in the vascular system. The access route is through the inferior vena cava to the right atrium, where a trans-septal puncture, followed by advancement of the catheter is completed. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement through the atrial septum into the left atrium. The distal end of the sheath is expanded using a radial dilator. In one application, the sheath is utilized to provide access for a diagnostic or therapeutic procedure such as electrophysiological mapping of the heart, radio-frequency ablation of left atrial tissue, placement of atrial implants, valve repair, or the like.
