Abstract: Perfusion systems and methods are provided for increasing peripheral blood flow to reduce limb ischemia, in which an extracorporeal pump having a controller, and catheter/tubing set, employed alone or in conjunction with an interventional or circulatory assist device, withdraws blood from a patient's vasculature and reintroduces that blood at another location within the patient's vasculature at a controlled local pressure or flow rate, without interfering with operation of the interventional or circulatory assist device or surgical intervention.

Abstract: Endovascular variable aortic control catheters (EVACC) are provided that are adapted to augment upstream blood pressure and regulate downstream blood flow for patients in shock. The EVACC devices provide improved treatment for truncal wounds, which may be used for example on a battlefield, thereby increasing survivability of injured soldiers. The devices are a catheter-based system having a proximal hand piece for controlled deployment of the device through a delivery sheath. A collapsible, wire framework supports an expandable and collapsible occlusion barrier. The wire basket and occlusion barrier expand to fit within the lumen of the aorta. Various movable elements are used to adjust an adjustable passageway to regulate controlled anterograde blood flow.

Abstract: A blood pump assembly comprises a balloon defining an elongated inflatable chamber with an opening at the proximal end. The proximal region of the balloon is substantially cylindro-conically shaped, and tapering toward the proximal end of the balloon, the central region of the balloon is substantially cylindrically shaped with a substantially uniform exterior diameter. The distal region of the balloon is substantially cylindro-conically shaped, the distal region of the balloon tapering toward the distal end of the balloon. The length of the distal region of the balloon is greater than approximately 15% of the combined length of the proximal and central regions of the balloon. A driveline may be coupleable to the opening and have a connection element disposed at a proximal end of the driveline. A radio opaque marker may be integrated into the driveline at a distal end of the driveline.

Abstract: The invention relates to a catheter assembly for the intermittent occlusion of the coronary sinus (CS, 60). The catheter assembly comprises a shaft (17, 126). The shaft (17, 126) has a plurality of lumens (7A, 7B, 35, 38, 40, 40A, 40B), a distal end (22) with a distal tip (20A, 20B, 20C), an occlusion device (24, 56, 142) fixed to the distal tip (20A, 20B, 20C) and operable through at least one of the plurality of lumens (7A, 7B, 35, 38, 40, 40A, 40B) and a proximal handle (10). The catheter assembly further having at least one of the following:

the occlusion device (24, 142) having a diameter of 5 - 20 mm and adapted to occlude the coronary sinus ostium,
means of measuring the pressure at the distal tip (20 a, 20B, 20C) of the catheter assembly and distally to the occlusion device (24, 142), preferably using an optical pressure sensor (28),
an anchoring device (30, 54, 65, 80, 90A, 122) for anchoring the occlusion device (24, 142) in a predefined position in the coronary sinus (CS, 60), preferably in the ostium,
the distal end (22) being deflectable/steerable with deflection being controlled by an actuator arranged at the proximal handle (10).

Abstract: A circulatory assist apparatus comprises an inflatable pumping balloon having a proximal end joined to an elongated balloon catheter, the catheter having a distal end joined to the pumping balloon and a proximal end, separated from the distal end by a length sufficient to extend from within the circulatory lumen to the outside of a patient's body, for receiving positive and negative pressure pulses from a pump to inflate and deflate the pumping balloon; a proximal expandable frame comprising a distal portion of an elongated shaft surrounding the catheter; and a distal expandable frame. The distal end of the elongated shaft is abuttable against a stopping element surrounding the catheter as the shaft is advanced towards the inflatable pumping balloon, or is joined to the catheter in which case the proximal expandable frame is heat set to deploy spontaneously to a predetermined diameter upon release of the elongated shaft.
