Abstract:
A Retrograde Entry Antegrade Placement (REAP™) method and apparatus facilitate the antegrade (i.e., in the direction of blood flow) placement of endovascular devices for treatment of lower extremity arterial disease. Initially, a retrograde entry is made into the arterial system of a patient at an entry point with a curved needle, which then exits at an exit point proximal to the entry point, with a first wire then passed through the lumen of the curved needle. From the skin exit point, a Dual-Lumen Access Director (DAD) device is advanced in the antegrade direction down the first wire in a first lumen and enters the CFA 1 lumen. A second wire is passed down a second lumen in the DAD device and follows the SFA lumen in the antegrade direction. The DAD device is removed, and a standard dilator and sheath is inserted over the second wire and the endovascular treatment begins.
