摘要： Guide catheter exchange device and method of exchanging a guide catheter. The guide catheter exchange device includes a magnetically responsive segment located on a proximal end for maintaining a previously placed guide wire in position across a stenosis, while performing a guide catheter exchange procedure. The guide catheter exchange device allows a guide catheter exchange procedure to be performed by a solo physician.

摘要： The present invention is a device and method for controlling longitudinal movement of a tube relative to a shaft slidably disposed within the tube, especially in the catheterization of a patient. An operative segment on the shaft cooperates with an ancillary tool to create a coupling force field between the shaft and the tool. The tube can then be moved over the shaft while the coupling force field operates through the tube to restrict the movement of the shaft. In the preferred embodiment, the shaft is a guide wire and the tube is a catheter with a lumen for slidably receiving the guide wire, while the coupling force field is created magnetically. In one embodiment, the operative segment is borne on a short guide wire extension which is selectively securable to a standard guide wire.
摘要翻译：本发明是一种用于控制管相对于可滑动地设置在管内的轴的纵向运动的装置和方法，特别是在患者的导管插入中。轴上的操作段与辅助工具协作以在轴和工具之间产生联接力场。然后，管可以在轴上移动，同时耦合力场通过管操作以限制轴的运动。在优选实施例中，轴是导丝，并且管是具有用于可滑动地接收导丝的内腔的导管，而耦合力场是磁力产生的。在一个实施例中，操作段承载在可选择性地固定到标准导丝的短导丝延伸部上。

摘要： Instrumentation for facilitating cutting an opening in a side wall of a body conduit in a patient. A tubular structure defines a lumen and has a sharpened distal end portion configured to cut a section of the body conduit to create the opening. A tissue holding structure is provided which is axially movable within the lumen of the tubular structure. The tissue holding structure includes a piercing portion to permit passage of the tissue holding structure through the body conduit from an entrance side to an exit side thereof. The tissue holding structure also includes a retention member to secure the section of the body conduit to the tissue holding structure during movement of the tissue holding structure to approximate the entrance side of the body conduit with the sharpened distal portion of the tubular structure to enable the sharpened distal structure to cut the body conduit. A connector is also provided for attaching a new length of tubing to the body conduit at the opening made by the cutting.
摘要翻译：用于促进切割患者体内导管侧壁中的开口的装置。管状结构限定内腔并且具有被设计成切割身体导管的一部分以形成开口的锋利的远端部分。提供组织保持结构，其可在管状结构的内腔内轴向移动。组织保持结构包括刺穿部分，以允许组织保持结构通过体导管从入口侧到出口侧。组织保持结构还包括保持构件，用于在组织保持结构的移动期间将身体导管的部分固定到组织保持结构，以与管状结构的锋利的远端部分接近体导管的入口侧，使得能够削尖的远端结构切割体导管。还提供连接器，用于在通过切割制成的开口处将新长度的管连接到主体导管。
