An apparatus and methods are provided for a double balloon vascular occlusion catheter. The double balloon vascular occlusion catheter includes a catheter for reaching an injury site within an artery. The catheter includes a central lumen for receiving a wire to guide the catheter to the injury site. A distal aspect of the double balloon vascular occlusion catheter includes proximal and distal balloons for being inflated on opposite sides of the injury site. A space between the balloons provides a blood occlusion segment of the catheter when the balloons are inflated. Inflation tubes and luer-locks at a proximal aspect of the double balloon vascular occlusion catheter enable inflation of the balloons. The double balloon vascular occlusion catheter may include a bidirectional lumen that causes unobstructed blood flow to bypass the blood occlusion segment.

A balloon embolization apparatus, system and method include a detachable balloon device mounted to the distal end of a catheter or microcatheter. The balloon device includes an elongated cannula having first and second axial lumens defined in the cannula, one lumen which allows for travel over a wire, an inflatable balloon disposed on the cannula, and a valve sleeve disposed between the balloon and the cannula. An inflation port on the cannula allows fluid to be introduced to the balloon via a channel in the catheter. The valve sleeve includes a vent offset from the inflation port in the cannula. The valve sleeve allows the introduced fluid to inflate the balloon, but prevents the fluid from escaping, thereby forming a check valve. Once inflated, the catheter is detached from the balloon apparatus. When the catheter is withdrawn, the balloon remains in place to allow for embolization.

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 balloon embolization apparatus, system and method include a detachable balloon device mounted to the distal end of a catheter or microcatheter. The balloon device includes an elongated cannula having first and second axial lumens defined in the cannula, one lumen which allows for travel over a wire, an inflatable balloon disposed on the cannula, and a valve sleeve disposed between the balloon and the cannula. An inflation port on the cannula allows fluid to be introduced to the balloon via a channel in the catheter. The valve sleeve includes a vent offset from the inflation port in the cannula. The valve sleeve allows the introduced fluid to inflate the balloon, but prevents the fluid from escaping, thereby forming a check valve. Once inflated, the catheter is detached from the balloon apparatus. When the catheter is withdrawn, the balloon remains in place to allow for embolization.

In some examples, a catheter includes an elongated member including at least one balloon connected to the elongated member, the at least one balloon being configured to inflate to an expanded state. In the expanded state, the at least one balloon forms at least a portion of a cavity with a wall of a vessel of the patient. The catheter including at least one electrode carried by the elongated member and having at least one surface exposed to the cavity formed by the at least one balloon. The electrode is configured to connect to an energy source that is configured to deliver, via the electrode, an electrical signal to a fluid contained in the cavity and in contact with the electrode to cause the fluid to undergo cavitation to generate a pressure pulse wave within the fluid.

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

A medical device and a medical device set are disclosed capable of improving passability of a balloon catheter through a body lumen and protection of a balloon. The medical device is an auxiliary device for the balloon catheter, and the medical device has an elongated base shaft, and a distal end member including an extending portion that extends along a longitudinal direction of the base shaft and a balloon protecting portion that is provided on a distal end side relative to the extending portion and is formed in a spiral shape. The balloon protecting portion includes a space portion configured to at least partially accommodate the balloon of the balloon catheter that is provided inward in a radial direction of the spiral shape, and a tapered portion having an outer diameter which decreases toward the distal end side.

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.

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

Methods, devices, systems of resuscitating a patient including accessing an arterial vessel positioning a catheter into the arterial vessel advancing the catheter through the arterial vessel to position it below a vessel supplying blood to a heart and a brain expanding an expandable portion of the catheter to prevent blood from flowing past the expanded portion and infusing a substance retrograde into the artery within the arterial section between the heart and the expanded portion of the catheter.
