摘要： 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.

摘要： 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.
摘要翻译：本发明涉及一种导管，其被配置成通过导管的工作腔自我调节吸气速率。导管包括与工作内腔连通的顺应构件，其构造成当超过预定吸气阈值时从打开位置转换到关闭位置。在关闭位置，柔顺构件暂时向内拉，以至少部分地阻塞通过工作腔的流动，从而减轻施加在患者血管上的抽吸速率。当吸气速率降低到阈值水平以下时，顺从构件返回到打开位置。

摘要： Apparatus and methods for treatment of stroke are provided. In a preferred embodiment, the present invention disposes at least one catheter (41) having a distal occlusive member (42) 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 (41) independently to effectively control cerebral flow characteristics. Under such controlled flow conditions, a thrombectomy device (200) may be used to treat the occlusion, and any emboli generated are directed into the catheter(s).

摘要： Methods and apparatus are provided for removing emboli during an angioplasty, stenting or surgical procedure comprising a catheter having a funnel-shaped occlusion balloon (42) of uniform thickness disposed on a distal end of the catheter (41). The occlusion balloon is fused (67) to the distal end so that it provides a substantially seamless flow transition (72) into a working lumen of the catheter (Fig 3A). Additionally, a distal edge (68) 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.

摘要： Methods and apparatus are provided for removing emboli generated during a surgical procedure comprising a catheter (21) having proximal and distal ends, a lumen (35) extending therethrough, an occlusive member affixed to the distal end, and at least one blood intake port disposed in a lateral surface of the catheter. The occlusive member (22) preferably is disposed in a treatment vessel, and the blood intake port (25), when uncovered, permits a portion of the antegrade flow from a host vessel to be diverted into the lumen (35) of the catheter (21). A pressure differential caused by the blood intake from the host vessel establishes a venturi-effect suitable for manipulating flow in the treatment vessel. The flow .characteristics may be manipulated via the intake port (25) to direct emboli into the lumen (35) of the catheter (21) for subsequent removal.

摘要： The device comprises a guide wire (14) having a lumen (34) inside the guide wire (14). The guide wire (14) has one end occluded (24), the other end open (36), and has a balloon (20) at the occluded end (24). A core segment (30) is inserted into the open end (36) of the guide wire (14), and may be removed from the guide wire (14) when the open end (36) of the guide wire (14) is inside a basin full of normal saline mixed with non-ionic contrast media. When the core segment (30) is removed, it creates a vacuum inside the lumen (34) of the guide wire (14) which is filled immediately with the solution. Then, the core segment is gently advanced until the guide wire balloon (20) is fully distended. Through a locking mechanism the core segment is kept in position. Coaxial systems, such as balloon catheter, and stent delivery systems, can be applied over the guide wire (14) without deflating the guide wire balloon (20).
