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. The aspiration sub-system is adapted to remove at least a second portion of the unwanted material from the vessel. The aspiration sub-system also includes a pressure sensor adapted to monitor internal vessel pressure proximate an internal region of the vessel.

Abstract: A system for dislodging and removing occlusions from a vascular vessel. The system includes a handle and an elongate member, the elongate member including an occlusion dislodging member adapted to axially move, radially expand and contract, and rotate to dislodge vessel occlusions. The handle is adapted to selectively induce the axial movement, radial expansion and contraction, and rotation of the occlusion dislodging member.

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. The medical device also includes means for delivering a pharmacological agent composition to the vessel occlusion site during and after the occlusion extraction, the pharmacological agent composition adapted to at least partially lyse and/or disassociate the occlusion from the vessel wall or ameliorate and/or facilitate amelioration of tissue damage to an endothelial luminal wall of an obstructed vessel in vivo and/or enhance the flow rate of blood through the vessel. The aspiration sub-system being in communication with the retriever sub-system and adapted to remove at least a portion of the occlusion from the vessel.

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. The handle has at least one actuation mechanism and at least one of the following applies: a) the first expandable member is coupled to the at least one actuation mechanism and is configured to be moveable relative to the second expandable member upon manipulation of the at least one actuation mechanism; b) the first expandable member is configured to mechanically expand or contract by manipulating the at least one actuation mechanism; c) the second expandable member is coupled to the at least one actuation mechanism and is configured to be moveable relative to the first expandable member upon manipulation of the at least one actuation mechanism; or d) the second expandable member is configured to mechanically expand or contract by manipulating the at least one actuation mechanism.
