Abstract
The medical device can comprise a manipulation member, a mechanical thrombectomy apparatus attached to a distal end of the manipulation member, and flow-restricting apparatus attached to the manipulation member to a location proximal to the mechanical thrombectomy apparatus. A method, for retrieving thrombus from a blood vessel, can comprise advancing a single elongate delivery member carrying a mechanical thrombectomy apparatus and a flow-restricting apparatus through a catheter to the blood vessel, expanding the thrombectomy apparatus and capturing the thrombus with the thrombectomy device, expanding the flow-restricting apparatus to at least partially occlude blood flow toward the thrombus, retracting at least a portion of the thrombectomy apparatus into the flow-restricting apparatus, and retracting the flow-restricting apparatus and the thrombectomy apparatus into the retrieval catheter.
