摘要： Percutaneous devices (200, 300, 400, 500, 600, 700, 800) and methods for releasably engaging a guidewire (326, 426, 626, 726, 826) against an inner surface (338) of a tubular member are disclosed. A percutaneous device can include a tube member (214, 314, 414, 514, 615, 714, 814), a push member (216, 316, 416, 516, 616, 716, 816), and a fixation mechanism such as a fixation balloon (334, 434, 534, 634, 734, 834). The tube member can define a lumen (220, 420), sized and shaped to receive one or more interventional medical devices therethrough and can have an outer diameter smaller than a lumen (104, 204, 304, 604, 704, 804) of a guide catheter (102, 202, 302, 602, 702, 802). 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 (218, 318) 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.
