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.L'invention concerne des dispositifs percutanés (200, 300, 400, 500, 600, 700, 800) et des procédés permettant de mettre en prise de manière amovible un fil-guide (326, 426, 626, 726, 826) contre une surface interne (338) d'un élément tubulaire. Un dispositif percutané peut comprendre un élément tube (214, 314, 414, 514, 615, 714, 814), un élément de poussée (216, 316, 416, 516, 616, 716, 816), et un mécanisme de fixation tel qu'un ballonnet de fixation (334, 434, 534, 634, 734, 834). L'élément tube peut définir une lumière (220, 420), dimensionnée et façonnée pour recevoir un ou plusieurs dispositifs médicaux d'intervention à travers cette dernière et peut présenter un diamètre externe plus petit qu'une lumière (104, 204,
