摘要： A multi-lumen catheter comprising a loop-like structure at the distal portion of the catheter is disclosed herein. In one variation, the loop-tip catheter comprises a dual lumen catheter and a loop-like structure at the distal end of the catheter. The loop-like structure includes at least one lumen, which is in fluid communication with at lease one of the two lumens in the dual lumen catheter. One or more ports are provided on the loop-like structure for accessing the lumens within the loop. In another variation, the loop-tip catheter is configured with an arterial inlet positioned on an inner surface of the loop, while a venous outlet is positioned on an outer surface of the loop. Methods for making and using variations of the loop-tip catheter are also disclosed herein.

摘要： Apparatus is provided for accessing a body cavity comprising a tubular member having a deflated insertion configuration and an inflated expanded configuration that facilitates viewing within the body cavity. The apparatus is formed by everting a length of material upon itself to form a tube having a single circumference seam at the distal end, and includes an inflation tube that is sufficiently rigid to assist in inserting the tubular member into a body cavity in the deflated insertion configuration. The tubular member further includes a pattern of staggered contact areas that configured so as to avoid the creation of longitudinal features that preferentially bend when loaded, thereby ensuring that tubular member provides a substantially circular central lumen.

摘要： A catheter, having a substantially fluid-tight seal is provided. The seal can be used in a number of catheters, including an angioplasty catheter. The seal includes surfaces that are independently movable relative to one another. The effectiveness of the seal depends on the proximity of the surfaces, the surface are at the interface, pressure differential and viscosity of the fluid. The seal is used in connection with providing fluid-tight channels with surfaces that are relatively movable and to circumvent the need to separate hydraulic channels from other channels so that catheters can be provided with fewer channels. Further, catheters and catheter systems with smaller shaft dimensions or larger hydraulic channel dimensions is made possible. Balloon catheters using this seal have enhanced torque delivery and directional control.
摘要翻译：提供了具有基本上流体密封的导管。该密封件可用于多个导管，包括血管成形术导管。密封件包括彼此独立地可移动的表面。密封的有效性取决于表面的接近度，表面在界面处，压差和流体的粘度。密封件用于提供具有相对可移动的表面的流体密封通道，并且避免了将液压通道与其它通道分开的需要，使得导管可以设置有更少的通道。此外，具有较小轴尺寸或较大液压通道尺寸的导管和导管系统成为可能。使用该密封的气球导管具有增强的扭矩传递和方向控制。
