摘要： A system and method for monitoring the placement of a feeding tube in the jejunum of a patient includes a system comprising a feeding tube and a tubular member received in a passageway extending through the feeding tube. The tubular member is sized relative to the feeding tube such that an echogenic distal length of the tubular member extends distal to the open distal end of the feeding tube. The distal end of the assembly is advanced into the small intestine of the patient, and a negative pressure is drawn through an opening in the distal length of the tubular member to draw the tubular member distal length into juxtaposition with a wall of the small intestine. The position of the assembly in the small intestine may be observed in real time via ultrasound visualization of the echogenic portion.

摘要： The disclosure provides a catheter for positioning in a contralateral femoral approach in highly angulated iliac bifurcations. The catheter comprises an elongate shaft, an adjustable element, and a wire entrance port on the elongate shaft. The elongate shaft has a proximal portion, an intermediate portion, a curved portion, and a distal portion. The curved portion connects the intermediate portion and the distal portion. The adjustable element is configured to encompass the distal portion and the intermediate portion together in a closed position. The adjustable element can be removed away from the distal portion permitting the distal portion in an open position. The wire entrance port is disposed in the intermediate portion near the curved portion. The distal portion is biased to be spaced away from the intermediate portion in the open position. The adjustable element is connected to an operating wire configured to advance and retreat through the wire entrance port.

摘要翻译： 本公开提供了用于在高度角度的髂骨分叉中定位在对侧股骨方法中的导管。 导管包括细长轴，可调元件和细长轴上的线入口。 细长轴具有近端部分，中间部分，弯曲部分和远端部分。 弯曲部分连接中间部分和远端部分。 可调元件构造成将远端部分和中间部分一起包围在关闭位置。 可调节元件可远离远侧部分移开，允许远端部分处于打开位置。 线入口设置在靠近弯曲部分的中间部分。 远端部分被偏压以在打开位置与中间部分间隔开。 可调元件连接到被配置为通过导线入口端口前进和后退的操作线。
