摘要:
A device for performing therapeutic or diagnostic procedures within the cerebrovasculature includes a catheter having a distal portion, a proximal portion and a lumen extending therebetween, the catheter including an expandable region for engaging the vessel wall, thrombus, atheroma, or other structures. The device further includes an elongate stretching member, which can be a guidewire, insertable longitudinally through the lumen of the catheter, the elongate stretching member being configured for stretching at least a portion of the catheter and causing the expandable region to transition from an expanded state to a collapsed state, and wherein the elongate stretching member is retracted proximally relative to the catheter causes the expandable region to transition from the radially collapsed state to a radially, or laterally expanded state.
