Abstract: Systems, methods, and apparatus for securing nasal tubes are disclosed. An exemplary system includes a bridle, a magnetic portion connected to the bridle, a delivery probe, a retrieval probe, and a clamp. The delivery probe includes an elongated member having proximal and distal ends, the distal end configured to deliver the magnetic portion, and a bridle lock configured to release the bridle upon actuation of an actuator. The retrieval probe includes an elongated member having proximal and distal ends, the distal end including a magnetic portion configured to magnetically couple with the other magnetic portion, and a magnetic coupling indicator configured to provide an indication in response to a magnetic coupling. The clamp includes a channel portion with an inside diameter larger than an outside diameter of a nasal tube. The clamp is configured to secure the nasal tube following placement of the bridle by the delivery and retrieval probes.

Abstract: A balloon catheter has an inner tube communicating with a blood introduction port provided at a tip of the balloon portion. The inner tube is affixed to the inner wall of the catheter tube by adhesion, melt-bonding, or integral formation. The balloon catheter has a small channel resistance in the channel where the pressurized fluid which expands and contracts the balloon portion flows, even when the catheter tube has been bent, and enables expansion and contraction of the balloon portion with a good response. Another balloon catheter has the balloon portions at a range of the end sides of the balloon portions smaller in sectional area compared with the balloon portions at the tip sides. The catheter is able to effectively prevent side effects which occur only rarely but which are serious when they do occur. The catheter impairs as little as possible the effect of assisting the heart action inherent to the IABP method without special measurement of the diameter of the patient's blood vessels.
