摘要： A guidewire steering device includes a gripping member and a compression member. The gripping member includes opposed first and second gripping surfaces positioned for selective engagement of a guidewire positioned therebetween. The first gripping surface includes a first end and a second end and the second gripping surface includes a first end and a second end. The first and second gripping surfaces being oriented to permit selective gripping of a guidewire positioned therebetween. The second end of the first gripping surface and the second end of the second gripping surface are spaced apart in a manner defining a lateral access slot through which a guidewire may be passed for positioning between the first and second gripping surfaces. The compression member is positioned about the gripping member for controlling movement of the first and second gripping surfaces between a gripping orientation in which the first and second gripping surfaces engage a guidewire positioned therebetween and a sliding orientation in which the first and second gripping surfaces are sufficiently spaced to permit free movement of a guidewire therebetween. The compression member includes first and second outwardly extending arms which respectively wrap about an exterior surface of the gripping member adjacent the first and second gripping surfaces to force the first and second gripping surfaces toward each other when the compression member is moved toward the gripping member.

摘要： A biopsy needle for collecting a tissue specimen includes an outer cannula that is at least partially received within a handle housing and an inner tube received within the outer cannula and configured to receive a stylet. A snare coil is attached between the inner tube and the outer cannula and a movable base is disposed within the handle housing. The outer cannula is fixedly coupled to the base and the movable base is axially movable within the handle housing. An inner driven structure that is coupled to the inner tube is configured to travel axially across an upper surface of the movable base. The coupling between the inner driven structure and the inner tube is such that the axial driving of the inner driven structure imparts rotation to the inner tube relative to the outer cannula.
