摘要：

An anatomic device delivery and positioning system has a stabilizing guide wire for placement of a catheter or other medical device or material into a vessel or cavity of a tissue or organ within a body of a living subject into which the guide wire is insertable. The guide wire includes an elongated member having a proximal end and a distal end, the proximal end to extend out of the body and the distal end to extend into the body, the distal end having an expandable portion that expands from a compressed condition when inside of a delivery tube or catheter to an expanded condition when outside of the delivery tube or catheter. A method is also disclosed of performing a percutaneous procedure within a vessel or cavity of a tissue or organ of a subject using the guide wire, particularly but not exclusively involving a heart procedure.
