Abstract: A clot removal device for removal of an occlusion from a lumen in a patient's body is provided. The clot removal device has a lumen, an elongated member positioned within the lumen and extending axially from a proximal end to a distal end of the lumen, a handle attached to the proximal end of the lumen, a first expandable member positioned along a length of the elongated member, a second expandable member positioned along the length of the elongated member, wherein the second expandable member is distal to the first expandable member relative to the handle.

Abstract: A method for retrieving a mixture of clot material and blood from a vessel of a patient and isolating the blood from the mixture for reinfusion into the patient. The method including the step of providing a blood reinfusion system adapted to extract the mixture of clot material and blood from the vessel and isolating the blood for reinfusion into the subject.

Abstract: A medical device for removal of an occlusion from a vessel in a patient’s body. The retrieval device having a retriever sub-system and an aspiration sub-system. The retriever sub-system having a delivery catheter and an elongated delivery member that includes proximal and distal expandable elements, the proximal element being removably engaged to the elongated delivery member and the distal element being fixed to the elongated delivery member. The proximal element adapted to move axially along the elongated delivery member in a distal direction toward the distal element when the proximal element is released from the elongated delivery member, whereby, when the proximal element is disposed on a distal side of the vessel occlusion and the distal element is disposed on a proximal side of the occlusion, the proximal and distal elements surround, isolate and contain the occlusion between the proximal and distal elements at the vessel occlusion site.

Abstract: A retriever device for removal of unwanted material from a vessel in a patient's body comprising a retriever sub-system and an aspiration sub-system. The retriever sub-system comprising a delivery catheter and a delivery wire having first and second expandable bodies disposed thereon that are adapted to expand from a pre-expansion configuration to an expanded configuration. The second expandable body is further adapted to slidably translate along the delivery wire in a distal direction toward the first expandable body when the second expandable body is released from the delivery wire, whereby, when the first expandable body is disposed on a distal side of at least a first portion of the unwanted material in the vessel and the second expandable body is disposed on a proximal side of the first portion of the unwanted material, the first expandable body and the second expandable body surround and contain the first portion of the unwanted material between the first expandable body and the second expandable body.
