摘要： A coaxial guide catheter to be passed through guide catheter having a first lumen, for use with interventional cardiology devices that are insertable into a branch artery that branches off from a main artery. The coaxial guide catheter is extended through the lumen of the guide catheter and beyond the distal end of the guide catheter and inserted into the branch artery. The device assists in resisting axial and shear forces exerted by an interventional cardiology device passed through the second lumen and beyond the flexible distal tip portion that would otherwise tend to dislodge the guide catheter from the branch artery.
摘要翻译：要穿过具有第一腔的引导导管的同轴引导导管，用于可插入从主动脉分支的分支动脉的介入心脏病学装置。同轴引导导管延伸穿过引导导管的内腔并超过引导导管的远端并插入分支动脉。该装置有助于抵抗由介入心脏病学装置施加的轴向和剪切力，所述介入心脏病学装置通过第二腔并超出柔性远侧末端部分，否则其将倾向于将引导导管从分支动脉移开。

摘要： An irrigation catheter having at least two lumens for supplying irrigation fluid in minimally-invasive surgical procedures is revealed. The catheter works alongside but independently of an endoscope or other diagnostic or therapeutic instrument. The catheter may direct flow of the irrigation fluid in the same direction as the body's natural flow, thus enhancing visualization by the endoscope or other instrument.

摘要： A dual lumen aspiration catheter system with an aspiration catheter, a hub and a flexible strain relief, and a suction assembly. The aspiration catheter includes multiple successively connected flexible tubular components each increasing in relative flexibility in the distal direction, the most proximal tubular component connectingly extending from the hub and through the flexible strain relief. The tubular components of the aspiration catheter include, in order proximally to distally, a composite tube, an intermediate tube, a dual lumen tube, and a flexible tip tube. The dual lumen tube includes eccentrically co-located large and small tubular portions forming eccentrically co-located large and small lumens to provide a minimum cross section. The distal end of the dual lumen tube includes a convex beveled edge. The convex beveled edge and the flexible tip tube singly or jointly inflict minimal traumatic contact with a vessel wall when urged along a tortuous vascular path.

摘要： A thrombus suction catheter which is a tube having a distal end opening formed by an angled cut surface. In the distal end opening, at least a part on the proximal end side of the cut surface is formed in a concave shape in an angled direction, and the distal end side of the cut surface is formed to be flat and flexible. With the distal end configuration, suction and crossing are significantly improved.

摘要： A vent cannula includes a tubular base having a primary longitudinal passage therein with a primary distal tip for insertion into a body vessel. The base has a tubular junction interconnected and extending at an acute angle having a secondary passage therein communicating with the primary passage. A flexible tube is slidably retained within the secondary passage. The flexible tube has a flexible distal portion with a flexible distal tip thereon, a flexible proximal portion with a side port therein and with a proximal handle. The flexible tube is initially positioned at a “first position” wherein the flexible distal tip is within the secondary passage; and is slideable to a “second position” wherein the side port of the flexible proximal portion is at the junction of the primary and secondary passages, and the flexible distal tip is inserted into the primary passage and extended from the primary distal tip to thereby extend the functional tip of the cannula. In a first embodiment, the proximal portion of the flexible tube is sealed within the base by a flexible sleeve; and in a second embodiment, the flexible tube is sealed with elastomeric washers retained between the base and an end cap.

摘要： A sheath catheter used to compress and/or retrieve a filter from a body lumen. The sheath catheter includes an elongate proximal shaft and a distal recovery sheath. The proximal shaft includes a central lumen that accommodates a shaft portion of a solid core wire to provide the catheter with better pushability. The solid core wire further includes a coiled portion that extends within the recovery sheath from a distal end of the proximal shaft. The coiled portion of the core wire provides a transition in flexibility from the stiffer proximal shaft to the more flexible recovery sheath. The recovery sheath further includes a sheath lumen that is sized to receive the filter therein.

摘要： Methods are provided for partial aortic obstruction for cerebral perfusion augmentation in patients suffering from global or focal cerebral ischemia. Alternatively, the methods can be used to partially obstruct aortic blood flow to condition the spinal cord to secrete neuroprotective agents prior to abdominal aortic aneurysm repair. Partial obstruction of a vessel can be accomplished by a device comprising an elongate catheter and a distally mounted expandable member. The expandable member may comprise one or two balloons. Other medical devices, such as an angioplasty, stent, or atherectomy catheter, can be inserted distal the expandable member to provide therapeutic intervention.

摘要： A delivery sheath for an intravascular emboli capturing filter including an elongate tube having a distal region having a reduced thickness distal wall region. The delivery sheath, according to the present invention, can have a thinner, softer, distal most portion for superior and more benign interaction with vessel interior walls. The present invention includes an intravascular emboli filter system including an elongate shaft having a distal region, an expandable emboli filter operably coupled to the elongate shaft distal region, and an elongate sheath having a lumen therethrough disposed over the elongate shaft. The elongate sheath can have a distally decreasing outside diameter taper or reduced wall thickness region having improved atraumatic characteristics.
