Abstract
Methods and devices are disclosed that enable safe, rapid and relatively short and straight access to the cerebral arteries for the introduction of interventional devices to treat acute ischemic stroke. In addition, the disclosed methods and devices provide means to securely close the access site to the cerebral arteries to avoid the potentially devastating consequences of a transcervical hematoma.
Claims25
A method for accessing a cerebral artery to treat acute ischemic stroke, comprising:
- forming a transcervical puncture opening through a wall of a common carotid artery;
- inserting through the puncture opening an arterial access sheath system configured to be inserted directly into the common carotid artery without previously inserting an introducer sheath through the opening, the arterial access sheath system comprising:
- an arterial access sheath having an internal lumen extending between a proximal end region and a distal end region of the arterial access sheath;
- a dilator inserted through the internal lumen and extending distal from the distal end region of the arterial access sheath;
- and
- a first occlusion element coupled to a distal region of the arterial access sheath;
- providing access to the cerebral artery via the internal lumen of the arterial access sheath;
- and
- expanding the occlusion element of the arterial access sheath to occlude an artery selected from the group consisting of the common carotid artery and an internal carotid artery.
6 more elements
A system for treating acute ischemic stroke, comprising:
- an arterial access sheath comprising an internal lumen extending between a proximal end region and a distal end region, wherein the arterial access sheath is adapted to provide access to a cerebral artery through a puncture opening in a wall of a common carotid artery;
- a dilator adapted to be inserted through the internal lumen and extending distal to the distal end region of the arterial access sheath;
- and
- an occlusion element coupled to the arterial access sheath at a distal region of the arterial access sheath, wherein the occlusion element is adapted to expand and occlude an artery selected from the group consisting of the common carotid artery and an internal carotid artery.
