Embodiments can provide an expandable nasogastric intubation assembly, comprising a tube subassembly and an expander subassembly, comprising an inflatable balloon comprising a proximal expander component section and a distal expander component section wherein the proximal expander component section is located between the proximal end of the intubation assembly and the distal expander component section; wherein the distal expander component section is located between the distal end of the intubation assembly and the proximal expander component section; wherein the inflatable balloon is coupled to the tube subassembly, the proximal expander component section is configured to be inflated from an injection of fluid into at least one first opening located in the second passageway, and the distal expander component section is configured to be inflated by the injection of fluid into at least one second opening located in the second passageway.

An airway catheter (AC) includes a catheter tube having proximal and distal tube end faces in fluid communication with a tube lumen. The distal tube end face and a portion of the tube wall collectively form a distal tube end region. A plurality of side holes extend laterally through the tube wall. An inflatable cuff is secured to the outer tube wall surface with an inner cuff volume in fluid communication with the tube lumen via the side holes. A resistor plug has proximal and distal plug end faces in fluid communication with a plug lumen and is defined laterally by a plug wall. The resistor plug is maintained within at least a portion of the tube lumen in the distal tube end region with an outer plug wall surface being at least partially in compressive contact with the inner tube wall surface.

Expandable intubation assemblies and methods for using and making the same are provided.

An occluding catheter for preventing stroke by occluding blood flow to right and left carotid arteries is provided. The occluding catheter includes a shaft that has a proximal end and a distal end, and a proximal occluding balloon carried by the shaft. The proximal occluding balloon is inflated to occlude blood flow through one of the right carotid artery and the left carotid artery. A distal occluding balloon is carried by the shaft and is inflated to occlude blood flow through one of the right carotid artery and the left carotid artery that is not occluded by the proximal occluding balloon. The shaft has a segment that is located between the proximal occluding balloon and the distal occluding balloon. Also provided are alternative arrangements with a single or dual inflation and/or guidewire channel, single occluding balloon, and an associated method of diverting emboli from cerebral circulation.

A stent delivery balloon catheter assembly includes a catheter that defines exactly one or two lumens, which includes an inflation lumen that extends from an inflation port at a proximal end to open through a distal end of the catheter. The catheter defines a wire guide channel that terminates at a wire guide exit located a distance from the distal end of the catheter. A balloon with a closed distal end is attached to the catheter distally of the wire guide exit, and extends distally beyond the distal end of the catheter. The balloon is in fluid communication with the inflation lumen. A column strength stiffener has a proximal end attached to the catheter distally of the wire guide exit, and has a balloon support segment extending distally away from the distal end of the catheter within the balloon. A distal end of the column strength stiffener is attached to the closed distal end of the balloon

A method and device for positioning an expandable support in a blood vessel is disclosed herein. The device may include a handle, a catheter assembly, a core wire, and an expandable support. The expandable support may be used to position the device relative to the arteriotomy, as well as to provide temporary hemostasis. The expandable support may be attached to the catheter assembly at a first end, and to the core wire at a second end to optimize the width of the expandable support based on the function being performed by the expandable support at a given time. The catheter assembly may be able to move relative to the handle and the core wire, thereby moving the first end of the expandable support relative to the handle and the core wire.

A coil-reinforced medical device delivery mechanism including a stiff proximal end for enhanced pushability and a soft distal end, including a free floating tip portion, for increased maneuverability and decreased breakage. The system utilizes a non-compliant balloon mounted on a flexible, single lumen shaft device with a support mandrel construction.

In intervertebral operative spinal procedures, using separate or pre-attached spreader blocks to control the directional growth of a distracting balloon.
