摘要： A expandable prosthesis having an imageable structure comprising one or more elements visually distinguishable by an external (e.g., radiographic or ultrasonic) imaging system, the structure being located about a first axis that corresponds to a structural feature of the prosthesis that is configured to perform a specific function particular to that axis. The imageable structure is configured to assist in the rotational orientation of the prosthesis during placement within the implantation site. In one embodiment the prosthesis comprises a venous valve that includes imageable elements or structure, such as a pair of radiopaque markers, that defines the orifice of the valve structure such that the orifice can be oriented with a particular anatomical feature under imaging, such as to align the orifice with the long axis of the vessel. In another embodiment, the imageable structure is configured to permit an aperture located about a stent graft to be oriented with a anatomical feature of the vessel, such as a branch vessel opening. The invention includes a method for using imageable structure to confirm that the orientation of the prosthesis within a delivery apparatus is consistent the desired delivery approach to be used.
摘要翻译：一种具有可成像结构的可扩张假体，其包括可由外部（例如，射线照相或超声）成像系统在视觉上区分的一个或多个元件，所述结构围绕与假体的结构特征对应的第一轴定位，所述第一轴被配置为执行特定于该轴的特定功能。可成像结构构造成在放置在植入部位期间有助于假体的旋转取向。在一个实施例中，假体包括静脉瓣，其包括可成像元件或结构，例如一对不透射线的标记，其限定瓣结构的孔，使得孔可以在成像下具有特定的解剖特征，诸如将孔与容器的长轴对齐。在另一个实施例中，可成像结构被配置为允许围绕支架移植物定位的孔与容器的解剖特征（例如分支血管开口）定向。本发明包括一种使用可成像结构来确认假体在输送装置内的取向与所要使用的输送方法一致的方法。

摘要： A flexible kink-resistant introducer sheath (10). The introducer sheath includes an inner liner (31), a coil (33) and an outer tube (20). The inner liner includes a passageway (30) extending longitudinally therethrough, where a catheter can be advanced through the passageway. The coil (33) has a plurality of turns positioned longitudinally and compression fitted around the inner liner (31), where the turns have a predetermined spacing therebetween. The outer tube (20) is positioned longitudinally around the coil (33) and the inner liner (31), and is connected to the inner liner through the spaces between the turns. A diameter difference between the inner liner and the catheter is in a range of about 0.0005 to about 0.004 inch (0.013 to about 0.10 mm).

摘要： A expandable prosthesis having an imageable structure (12) comprising one or more elements (13, 14) visually distinguishable by an external (e.g., radiographic or ultrasonic) imaging system (91), the structure being located about a first axis (97) that corresponds to a structural feature (24, 82) of the prosthesis that is configured to perform a specific function particular to that axis. The imageable structure is configured to assist in the rotational orientation of the prosthesis during placement within the implantation site. In one embodiment the prosthesis comprises a venous valve that includes imageable elements or structure, such as a pair of radiopaque markers, that defines the orifice of the valve structure such that the orifice can be oriented with a particular anatomical feature under imaging, such as to align the orifice with the long axis of the vessel. In another embodiment, the imageable structure is configured to permit an aperture located about a stent graft to be oriented with a anatomical feature of the vessel, such as a branch vessel opening
