  • Patent number: 7625337
    Abstract: Novel catheter constructions comprising thin covering or wrapping materials such as polymer films. A catheter provided with a guidewire catheter lumen having a thin covering that is easily punctured by a guidewire at virtually any desired point along the catheter length. The thin covering may be integral with the catheter shaft, or may be a separate component that covers only the portion of the catheter shaft immediately adjacent the outer portion of the guidewire lumen, or may be a thin tubular construct that surrounds the entire catheter shaft. Moreover, polymer film can be used in combination with one or more elements to produce novel catheter constructions.

  • Patent number: 7223253
    Abstract: The present invention is directed to a blood aspiration system that is configured to enable various types of aspiration through a working lumen of a catheter. The blood aspiration system facilitates natural aspiration by providing a circuit between a patient's arterial and venous vasculature, and also comprises a manually actuated pump configured to selectively vary rates of aspiration in the working lumen. The blood aspiration system further comprises an external port that allows suction-assisted aspiration or infusion through the working lumen, and further comprises a detachable filter that removes emboli prior to reperfusing blood into a patient's venous vasculature.

  • Patent number: 7063714
    Abstract: Apparatus and methods for treatment of stroke are provided. In a preferred embodiment, the present invention disposes at least one catheter having a distal occlusive member in either the common carotid artery (CCA) or both the vertebral artery (VA) and the CCA on the hemisphere of the cerebral occlusion. Blood flow in the opposing carotid and/or vertebral arteries may be inhibited. Retrograde or antegrade flow may be provided through either catheter independently to effectively control cerebral flow characteristics. Under such controlled flow conditions, a thrombectomy device may be used to treat the occlusion, and any emboli generated are directed into the catheter(s).

  • Patent number: 7033336
    Abstract: The present invention is directed to a proximal catheter assembly that is configured to facilitate natural or suction-assisted aspiration through a catheter lumen. The proximal catheter assembly comprises a relief valve configured to regulate the level of suction-assisted aspiration provided through the working lumen of the catheter. When the level of suction-assisted aspiration exceeds a predetermined threshold, the relief valve opens to allow fluid to be drawn from tubing coupled to the proximal catheter assembly, thereby mitigating the relatively high levels of aspiration imposed upon the working lumen and the patient's vessel.

  • Patent number: 7029488
    Abstract: Apparatus and methods for treating cerebral occlusions are provided, including a thrombectomy device having at least one deployable element. The deployable element is advanced through the occlusion in a contracted state, then self-deploys distal of the occlusion or, alternatively, may be deployed to a wide range of configurations using a physician-actuated deployment knob. The thrombectomy device then may be retracted to cause the deployable element to snare the occlusion, and/or rotated circumferentially to cause the fibrin strands of the occlusion to be wrapped around the deployable element.

  • Patent number: 7004931
    Abstract: The present invention is directed to a proximal catheter assembly configured to facilitate natural or suction-assisted aspiration through a catheter lumen. The proximal catheter assembly comprises a multi-function valve configured to perform functions associated with conventional check valves and relief valves. The valve is configured to regulate the direction of fluid flow, and further configured to regulate the rate of suction-assisted aspiration provided through the lumen of the catheter. When the rate of suction-assisted aspiration exceeds a predetermined threshold, the valve opens to allow fluid to be drawn from tubing coupled to the proximal catheter assembly, thereby mitigating excessively high rates of aspiration imposed upon the patient's vessel.

  • Patent number: 6960222
    Abstract: Methods and apparatus are provided for removing emboli during an angioplasty, stenting or surgical procedure comprising a catheter having a funnel-shaped occlusion balloon of uniform thickness disposed on a distal end of the catheter. The occlusion balloon is fused to the distal end so that it provides a substantially seamless flow transition into a working lumen of the catheter. Additionally, a distal edge of the occlusion balloon is configured to be in close proximity with an inner wall of a vessel to facilitate blood flow into the catheter and efficiently remove emboli.

  • Patent number: 6960189
    Abstract: The present invention is directed to a proximal catheter assembly that is configured to facilitate aspiration through a catheter lumen. The proximal catheter assembly enables natural aspiration to be achieved within the catheter lumen, for example, using an arterial-venous shunt, and further enables suction-assisted aspiration or infusion to be applied through the catheter lumen. This allows a physician to provide a substantially continuous level of retrograde flow within a vessel during a medical procedure without damaging the vessel wall, while providing the option of suction-assisted aspiration, when necessary, to further influence the level of aspiration within the vessel.

  • Patent number: 6908474
    Abstract: Methods and apparatus are provided for removing emboli during an angioplasty, stenting or surgical procedure comprising a catheter having an occlusion element, an aspiration lumen, and a blood outlet port in communication with the lumen, a guide wire having a balloon, a venous return sheath with a blood inlet port, and tubing that couples the blood outlet port to the blood inlet port. Apparatus is also provided for occluding the external carotid artery to prevent reversal of flow into the internal carotid artery. The pressure differential between the artery and the vein provides reverse flow through the artery, thereby flushing emboli. A blood filter may optionally be included in-line with the tubing to filter emboli from blood reperfused into the patient.

  • Patent number: 6887220
    Abstract: The present invention is directed to a catheter that is configured to self-regulate aspiration rates through a working lumen of the catheter. The catheter comprises a compliant member in communication with the working lumen that is configured to transition from an open position to a closed position when a predetermined aspiration threshold is exceeded. In the closed position, the compliant member is temporarily drawn inward to at least partially occlude flow through the working lumen, thereby mitigating the rate of aspiration imposed upon a patient's vessel. When the rate of aspiration is reduced below the threshold level, the compliant member returns to the open position.
