    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 a multitude of shapes and sizes allows users to access to a 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允许用户在手术或治疗期间不改变导管的情况下进入多个解剖区域。 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。

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: The present invention is directed toward a locking mechanism for aiding in the prevention of accidental or unintentional disengagement of the nozzle assembly from a needleless injection device. In one embodiment of the locking mechanism, a stud positioned on the nozzle assembly engages a recess in the injector to help to deter the nozzle assembly from rotating during firing of the injector. In another embodiment of the locking mechanism, a nib on the nozzle assembly engages a recess in the injector to deter the nozzle assembly from rotating during firing of the injector. A retaining element may be utilized within the injector to provide the recesses for engagement with the locking mechanisms.
