摘要： The invention provides a deflectable catheter capable of forming many variable radius spiral forms from a single, flexible, distal end section. In one aspect, the catheter employs a variable radius control wire to extend or deform a pre-formed loop structure into a three dimensional spiral-like form or geometry. The ability of a single catheter to create the multitude of shapes and sizes possible allows users to access a greater number of anatomical areas without changing the catheter during a procedure or treatment. In another aspect, the invention encompasses methods of producing deflectable variable radius catheters, where two or more regions of the catheter having common control wires are fused or formed onto one another.
摘要翻译：本发明提供了一种能够从单个柔性远端部分形成许多可变半径螺旋形状的可偏转导管。在一个方面，导管使用可变半径控制线来将预成形的环结构延伸或变形为三维螺旋形的形状或几何形状。单个导管创建多种形状和尺寸的能力可能允许用户在手术或治疗期间不更换导管的情况下进入更多数量的解剖区域。在另一方面，本发明包括生产可偏转可变半径导管的方法，其中具有公共控制线的导管的两个或更多个区域彼此熔合或形成。

摘要： Disclosed herein is a tool for implanting a medical lead. In one embodiment, the tool includes a body, an electrode, and a conductor. The body includes a distal end and a proximal end. The electrode is supported by the body. The conductor is in electrical contact with the electrode and extends along the body from the electrode to the proximal end. The electrode and conductor form an electrically conductive path that extends from a surface of the electrode to a proximal most point of the conductor on the body. The electrical resistance of the electrically conductive path is at least approximately 100 Ohms.

摘要： An implant tool for use with an endocardial or other implantable lead having an extendable/retractable active fixation tip includes a housing, a shaft rotatably supported by the housing, and a shaft rotation mechanism for rotating the shaft through a predetermined angular travel. The shaft includes a lead attachment portion for selectively coupling a lead to the shaft such that the lead is rotatable with the shaft. The implant tool may include a control tab slidably supported by the housing, wherein longitudinal movement of the control tab actuates the shaft rotation mechanism. The shaft rotation mechanism may include a gear train, an electric motor, a double acting spring mechanism, or a retractable tape wound around the shaft. The gear train includes an input member coupled to the control tab and an output gear coupled to the shaft. The input member meshes with an input gear supported by the housing.
