摘要： The invention relates generally to a de-aeration apparatus and system, and more particularly, to an apparatus and system suitable for de-aerating highly viscous fluids comprising a vacuum chamber, an annular disk for rotating within the chamber, and a fixed baffle covering a portion of the surface of the annular disk and thereby defining a predetermined path by which the fluid to be de-aerated is spread more quickly into a thinner layer on the disk, exposing a greater amount of air/gas bubbles from the fluid in a shorter amount of time and resulting in a higher quality product than conventional de-aeration systems allow.

摘要： A multistage balloon catheter that uses a single lumen to inflate a balloon in stages is disclosed. A fluid port provides fluid communication from an inflation lumen in the balloon catheter to the inner volume of a distal balloon. The distal balloon expands as fluid in delivered to the inner volume of the distal balloon. Once inflated, the pressure continues to rise until a threshold pressure is exceeded. A pressure sensitive inflation valve provides fluid communication into an inner volume of a second balloon disposed at least partially proximal to the distal balloon. The pressure sensitive valve allows fluid communication into the second balloon once the threshold pressure is reached in the first balloon thereby inflating the second balloon.

摘要： The disclosure provides an apparatus and methods for removing thrombosis in vessels. The apparatus includes a sheath catheter combined with an aspiration catheter. The sheath catheter includes a first sheath opening in a proximal end of the sheath catheter, a second sheath opening in a distal end of the sheath catheter, a first balloon disposed on an outer surface of the distal end of the sheath catheter, and a passageway extending between the first and second sheath openings. The aspiration catheter is configured to pass through the first and second sheath openings and the passageway of the sheath catheter. The aspiration catheter includes a second balloon, a plurality of infusion ports, and an aspiration port disposed on an outer surface of a distal portion of the aspiration catheter. A relative position between the sheath catheter and the aspiration catheter controls the number of unblocked infusion ports.

摘要： A medical device delivery system includes a retention sheath having a proximal portion and a bi-furcated distal portion having first and second sheath branch portions. The proximal ends of the sheath branch portions are joined together at a sheath branch junction. The system also includes an inner catheter disposed within the retention sheath. The inner catheter includes a proximal portion and a bi-furcated distal portion with first and second catheter branch portions. The proximal ends are joined together at a catheter branch junction. When the sheath is in an initial position, the catheter branch junction is displaced proximally from the sheath branch junction by a distance that is greater than or equal to the larger of a length of a first medical device and the length of a second medical device.
