发明名称 Catheter device for support of a guidewire in crossing a lesion
摘要 A catheter device selectively provides additional support to a guidewire for aiding the guidewire in crossing a narrowing in a body lumen. The catheter device includes an elongate outer tubular member having a tapered distal end. An elongate guidewire gripping member is slidably disposed within the outer tubular member. The guidewire gripping member has a lumen for slidably receiving the guidewire and a distal end having a plurality of longitudinal fingers. When the guidewire gripping member is advanced distally against the tapered distal end of the outer tubular member, a the fingers of the guidewire gripping member are forced to engage with the guidewire to thereby prevent movement of the guidewire relative to the catheter device. The catheter device may include a steering mechanism for steering the combined catheter device and guidewire component to an optimum starting point for crossing the lesion.
