摘要:
Embodiments of the invention include tools and methods for performing thrombectomy in patients' internal carotid arteries. A balloon guiding sheath in accordance with embodiments comprises an elongated 7-9 Fr sheath having a working section length of about ninety centimeters, an access port on a proximal end portion and a distal port on a distal end portion. A 6-8 Fr working lumen extends through the sheath between the access port and the distal port. An inflatable balloon is on the distal end portion of the sheath. An inflation lumen extends in the sheath between the balloon and an inflation port. The guiding sheath is configured with stiffness and other characteristics to enable direct insertion of the working length of the sheath into a patient's vasculature through an arteriotomy in the femoral artery, and to position the balloon in the internal carotid artery.
