<p>The disclosure provides a catheter (100) for positioning in a contralateral femoral approach in highly angulated iliac bifurcations. The catheter comprises an elongate shaft (20), an adjustable element (30), and a wire entrance port (22) on the elongate shaft. The elongate shaft has a proximal portion (40), an intermediate portion (50), a curved portion (60), and a distal portion (80). The curved portion connects the intermediate portion and the distal portion. The adjustable element is configured to encompass the distal portion and the intermediate portion together in a closed position. The adjustable element can be removed away from the distal portion permitting the distal portion in an open position. The wire entrance port is disposed in the intermediate portion near the curved portion. The distal portion is biased to be spaced away from the intermediate portion in the open position. The adjustable element is connected to an operating wire (70) configured to advance and retreat through the wire entrance port.</p> |
