Patent ID: 8529504

Claim:
A catheter comprising: an elongated flexible shaft including: a distal bending segment; a proximal bending segment; a main shaft that is proximal to the proximal bending segment; an activation element main lumen extending along at least a portion of the proximal bending segment and the main shaft; a first activation element satellite lumen which extends along at least a portion of the distal bending segment; and a second activation element satellite lumen which extends along at least a portion of the proximal bending segment; a first activation element anchored at a first anchoring point and extending proximally from the first anchoring point, through at least a portion of the distal bending segment within the first satellite lumen, through the proximal bending segment and into the main shaft; and a second activation element anchored at a second anchoring point and extending proximally from the second anchoring point, through at least a portion of the proximal bending segment within the second satellite lumen, and into the main shaft; wherein: the first satellite lumen starts a transition to the main lumen distal to the second anchoring point.
