摘要： A valve system for a catheter, such as an aspiration catheter, is disclosed and includes a valve having a proximal end and a distal end. The distal end of the valve is coupled to the catheter. The valve has a flexible lumen in a first state that is constricted or twisted. The valve system is housed within a hub, where actuation of a button on the hub causes the proximal and distal ends of the valve to rotate relative to each other to put the lumen in a second state that is unconstricted or untwisted state.

摘要： A medical device for removal of an occlusion at an occlusion formation site in 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 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 occlusion formation site. The medical device also includes means for delivering pharmacological and biologically active agents to the vessel occlusion site during and after the occlusion extraction, the pharmacological agents are 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 the vessel, the biologically active agents are also adapted to ameliorate and/or facilitate amelioration of tissue damage to an endothelial luminal wall of the vessel. The aspiration sub-system adapted to remove at least a portion of the occlusion during extraction of the occlusion from the vessel.

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.

摘要： The present specification is directed towards catheter devices having expandable and collapsible lumens. Air or fluid is pumped into the catheter wall to cause it to expand. Alternatively, wires are embedded within the wall and a direction of flow of electrical current through the wires is modulated to enable the catheter device to be in the collapsed or expanded state. For example, a first wire is embedded within the wall and is helically wound along a length of the catheter device. A second wire is provided that can be removably positioned within the lumen. The direction of flow of electric current through the first and second wires is modulated to enable the catheter device to be in the collapsed or expanded state.
