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.

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： An access device comprises a thin-walled sheath that is insertable into a patient through a small surgically created incision. The incision may be created using a cutdown or a percutaneous method such as that known as the Seldinger technique. Once inserted and advanced to the target surgical site, the sheath is selectively, and controllably, expanded to a desired diameter. The thin wall of the sheath is fabricated from a rectangular piece of material such as metal or plastic with two cut edges. The rectangular piece of metal or plastic is rolled tightly to create the small diameter configuration that is inserted into the patient. A cam or control member is affixed to the innermost edge of the rectangular piece of metal or plastic. The control member extends to the proximal most portion of the sheath. By rotating the control member, the operator causes the thin wall piece of rolled material to unfurl into a larger or smaller diameter, depending on the direction of rotation. A mechanical lock at the distal end of the sheath permits the control member to be selectively constrained from rotation and thus lock the sheath diameter in place.
摘要翻译：进入装置包括薄壁护套，其通过小的外科手术切口切入患者体内。可以使用切割或经皮方法（例如称为Seldinger技术）来创建切口。一旦插入并推进到目标手术部位，护套被选择性地且可控地扩张到期望的直径。护套的薄壁由诸如具有两个切割边缘的金属或塑料的矩形材料制成。将金属或塑料的矩形片材紧紧地卷起以产生插入到患者体内的小直径构型。凸轮或控制构件固定在矩形金属或塑料件的最内边缘上。控制构件延伸到护套的最近部分。通过旋转控制构件，操作者根据旋转方向使薄壁轧制材料展开成更大或更小的直径。在护套的远端处的机械锁允许控制构件被选择性地限制旋转，从而将护套直径锁定在适当的位置。

摘要： A transluminal sheath is disclosed that permits instrumentation to be passed therethrough. The transluminal sheath comprises a composite structure with an inner layer, an outer layer, and a reinforcing layer. The materials comprising the inner and outer layer are plastically deformable and maintain their shape, once bent into a specific configuration. The reinforcing layer further has radiopacity enhancing coatings to improve visibility under fluoroscopy and a system of flutes running longitudinally, to enhance fluid transport and reduce friction.
