Patent ID: 8235916

Claim:
A method of transferring a guidewire from one insertion site to another insertion site, comprising: introducing a first guidewire to a femoral access site, wherein said first guidewire has a proximal and a distal end; introducing the distal end of said first guidewire to a target site; introducing a catheter having a proximal end and a distal end from a subclavian access site and advancing the distal end to a proximity of said femoral access site; introducing a second guidewire, wherein said second guidewire has a proximal and a distal end, through the proximal end of said catheter such that the distal end of said second guidewire extends out through said femoral access site; emerging the distal end of said catheter through said femoral access site by advancing said catheter over said second guidewire; and exiting the proximal end of said first guidewire through the proximal end of the catheter at the subclavian access site by removing said second guidewire entirely from said catheter and inserting the proximal end of said first guidewire into the distal end of said catheter.
