A multiple balloon catheter designed to quickly and easily obtain hemostasis during open and minimal access surgery in the event of venous injury.

A device for secluding a body vessel may include a distal balloon, a proximal balloon, an aspiration port positioned adjacent to the distal balloon, an injection port positioned adjacent to the proximal balloon, and a lumen assembly. The lumen assembly may comprise a central lumen, a distal balloon lumen operably coupled to the distal balloon, a proximal balloon lumen operably coupled to the proximal balloon, an aspiration port lumen operably coupled to the aspiration port, and an injection port lumen operably coupled to the injection port. The distal balloon and the proximal balloon may define a treatment chamber therebetween, and the aspiration port and the injection port may be positioned within the treatment chamber on the lumen assembly.

A method for treating tissue of at least one of an internal carotid artery, an ophthalmic artery, or an ostium between the internal carotid artery and the ophthalmic artery of a subject may include expanding a first expandable device of a first device in the internal carotid artery. The method also may include delivering a second device in the ophthalmic artery via the first device and expanding a second expandable device of the second device in the ophthalmic artery. Further, the method may include adjusting a radial position of the second expandable device relative to the first expandable device.

A mechanotransductive bowel extender device that can be used to correct short bowel syndrome by applying tension to the bowel tissue which, via the process of mechanotransduction, grows in length in response to the applied tension. Such a device is placed within the small bowel and applies tension over a period of several days or weeks by attaching to the lumen of the bowel at two different locations and moving those two points apart, stretching the tissue between. The extender device further capable of localized application and/or evacuation of medically relevant liquid and other material within the bowel.

A system for use in prevention of stroke is provided that has a shaft that carries an occluding balloon. The occluding balloon is inflated to occlude blood flow through at least one of a right carotid artery and a left carotid artery. An actuation device for causing inflation of the occluding balloon is present. The inflation is applied in a cyclical nature based upon a cardiac cycle. The cyclical inflation of the occluding balloon in turn causes a resulting cyclical occlusion.

A double-balloon catheter device for gastrointestinal anastomosis. The double-balloon catheter device for gastrointestinal anastomosis includes a liquid injection assembly, a double-balloon assembly, and a supporting device (15) connecting the liquid injection assembly and the double-balloon assembly. The liquid injection assembly includes a first balloon liquid injection connection port (2), a guide wire connection port (3), and a second balloon liquid injection connection port (4). The double-balloon assembly includes a double-balloon catheter device (5), and includes a first balloon (6) and a second balloon (7) that can expand-and that are respectively disposed on the two ends of the double-balloon catheter device (5). The double-balloon catheter device (5) is provided with a first balloon liquid injection channel (51), a guide wire channel (52), and a second balloon liquid injection channel (53).

Some implementations of an endovascular device include a stent graft with an expandable tubular metallic frame and a covering material disposed on at least a portion of the metallic frame. The stent graft defines a lumen therethrough. In a particular embodiment, a first balloon is disposed around an outer periphery of the stent graft, a second balloon is disposed around the outer periphery of the stent graft and spaced apart from the first balloon, and a third balloon is disposed within the stent graft lumen between the first balloon and the second balloon. The third balloon can be inflated to fully or partially occlude the lumen. The first and second balloons can be individually inflated to fully or partially shunt blood flow from a blood vessel through the stent graft. In some embodiments, sensors and an automated control unit are included to automate the operations of the endovascular device.

A medical device for temporary deployment into a bodily lumen is provided. The medical device comprises: a guide wire cannula having a proximal end and a distal end; a tip attached to the proximal end of the guide wire cannula; a pusher having a proximal and a distal end, the pusher having a through-bore disposed around the guide wire cannula; and a temporary stent assembly having a proximal end attached to the tip and a distal end adjacent to the proximal end of the pusher. The temporary stent assembly comprises a covered portion. The covered portion has a proximal sealing zone, a distal sealing zone and a recess between the proximal and distal sealing zones.

A treatment of obstructive lung disease includes aiming a condensable vapor towards the airway wall, causing a band-shaped lesion to grow to a depth into the airway wall. Ablation parameters are set to control the depth of the band-shaped lesion to encompass the epithelial layer and exclude the smooth muscle layer of the airway. A wide variety of configurations of the vapor delivery are described to create ablation patterns in the airways of the patient with particular emphasis on treating chronic bronchitis.

In one aspect, an arteriovenous access valve system may generally include a first valve configured to be positioned at or adjacent to an end of arteriovenous graft and a second valve configured to be positioned at or adjacent to an opposite end of the arteriovenous graft. In addition, the system may include an actuator assembly in fluid communication with the first and second valves. The actuator assembly may include a housing, a driver assembly positioned within the housing and a drive magnet positioned within the housing. The drive magnet may be rotatably coupled to the driver assembly such that, when the drive magnet is rotated, the driver assembly is configured to be rotatably driven so as to supply fluid to the first and second valves or to draw fluid out of the first and second valves depending on a rotational direction of the driver assembly.
