摘要： 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.

摘要： A blood pump assembly has a balloon disposed at a distal region and a driveline disposed at a proximal region and is capable of being employed to provide mechanical circulatory support (e.g., counterpulsation). A blood pump support apparatus has a support structure with a head region and a tail region that is removably disposable in the blood pump assembly. When the support structure is disposed in the blood pump assembly, the head region is disposed within the balloon. When the blood pump assembly is implanted in the descending aorta and the support structure is disposed in the blood pump assembly, forces act on the balloon that would cause the balloon to roll or fold upon itself along an angle with respect to the balloon's longitudinal axis. The head region of support structure opposes these forces.

摘要： 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.

摘要： A percutaneous assembly is provided with a percutaneous sheath and a percutaneous dilator tip. The percutaneous sheath has a tubular wall extending to a distal end portion thereof and defines a lumen having an inner diameter. The percutaneous dilator tip includes a radially expandable member and an elongated control member. The radially expandable member is either removably engageable or fixedly attached to the distal end portion of the tubular wall and is also adjustable in an expanded and a contracted configurations. The elongated control member is disposed longitudinally along the tubular wall, positioned eccentrically relative to the lumen, and is operatively coupled to the radially expandable member for adjusting same in at least one of the expanded and the contracted configurations. A percutaneous sheath is also provided as kits.

摘要： In a method for intermittently occluding the coronary sinus, in which the coronary sinus is occluded using an occlusion device, the fluid pressure in the occluded coronary sinus is continuously measured and stored, the fluid pressure curve is determined as a function of time, and the occlusion of the coronary sinus is triggered and/or released as a function of at least one characteristic value derived from the measured pressure values. The pressure increase and/or pressure decrease per time unit each occurring at a heart beat are used as characteristic values.

摘要： The invention relates to a fluid pump having a housing delimiting a fluid chamber and having a conveying element for the fluid disposed in the fluid chamber, the housing, with respect to the shape and/or size thereof, being able to be changed between at least a first, expanded state and a second, compressed state. The object, to stabilise adequately a corresponding housing, is achieved according to the invention by the housing having at least one stabilisation chamber which can be supplied with a fluid pressure and is different from the fluid chamber, the first state of the housing being assigned to a first fluid pressure in the stabilisation chamber and the second state of the housing being assigned to a second fluid pressure.

摘要： Methods and apparatuses for pumping blood within a blood vessel are described. The methods and apparatuses can be used for renal decongestion by pumping blood through the kidney(s), thereby increasing a pressure gradient across the kidney(s). The apparatuses can include one or more inflatable elements that can be repeatedly inflated and deflated to cause a pumping action within the blood vessel. In some embodiments, the one or more inflatable elements are positioned within one or more stents.
