摘要：
Percutaneous devices and methods for releasably engaging a guidewire against an inner surface of a tubular member are disclosed. A percutaneous device can include a tube member, a push member, and a fixation mechanism such as a fixation balloon. The tube member can define a lumen sized and shaped to receive one or more interventional medical devices therethrough and can have an outer diameter smaller than a lumen of a guide catheter. The push member can be attached at least to a proximal end portion of the tube member for slidably positioning a distal end portion of the tube member within and beyond a distal end of the guide catheter. The push member can include a lumen in fluid communication with an interior of the fixation balloon for delivering inflation fluid to, or removing fluid from, the balloon. The fixation balloon can be positioned on a portion of the push member and can be configured to engage a guidewire against the inner surface of the guide catheter or the tube member when inflated.
