摘要： Described are methods and systems for transcervical access of the cerebral arterial vasculature and treatment of cerebral occlusions, including ischemic stroke. The methods and devices may include methods and devices which may provide aspiration and passive flow reversal, those which protect the cerebral penumbra during the procedure to minimize injury to brain, as well as distal catheters and devices to remove an occlusion. The methods and devices that provide passive flow reversal may also offer to the user a degree of flow control. Devices and methods which provide a way to securely close the access site in the carotid artery to avoid the potentially devastating consequences of a transcervical hematoma are also described.

摘要： A total artificial heart for a mammalian cardiovascular system is provided. The total artificial heart has a pump casing including an outer housing and an integral hollow support shaft extending therethrough. The casing defines a first flow path within the outer housing about an exterior of the hollow support shaft and a separate second flow path extending within the hollow support shaft. An annular impeller is housed within the outer housing of the casing for rotation about the hollow support shaft to provide a centrifugal flow pump in the first flow path, and an axial flow impeller is housed within the hollow support shaft of the casing for forming an axial flow pump in the second flow path.

摘要： A mechanical circulatory support system for a heart having a cooling element and a method for using the system to treat the effects of a cardiac episode. The support system has a pump having a distal end and a proximal end, the pump comprising a rotor, the rotor having at least one blade. The system also has a catheter having a distal end, a proximal end, and inner surface, and an outer surface, the catheter extending proximally of relative to the pump housing. The outer surface of the catheter is configured to contact blood when disposed within patient vasculature. The outer surface of the catheter comprises a heat transfer surface configured for cooling blood that comes in contact with the outer surface. The cooling element can be either a helix or double helix extending along a catheter surface or a Peltier element on the surface. The support system is operated to provide a temperature selected to cool the circulating blood in contact with the outer surface of the catheter to a temperature selected to reduce or prevent an effect of a cardiac episode

摘要： The invention relates to a rotor for a compressible fluid pump, in particular a blood pump that can be introduced through a blood vessel into a patient's body, wherein said rotor comprises one or more conveying elements (15), is compressible and expandable between a first compressed state and a second radially expanded state, is made at least partially from a plastic reinforced with reinforcing elements, in particular fibers (10, 11, 13, 18, 19, 55, 56, 62, 63) and is provided for rotation about an axis of rotation (14). According to the invention, the rotor is tensioned in the first, compressed state and free from external stresses in the second, expanded state. A third state exists, which the rotor (42) occupies in the operating state under load. The reinforcing elements, in particular fibers, extend in the rotor in the third state at least in sections in a stretched manner.

摘要： An apparatus for starting operation of a motor of an implantable blood pump including a memory storing one or more default parameters for at least one of controlling and monitoring the startup operation. A processor operatively coupled to the motor is included, the processor is configured to: commence the startup operation based on the one or more default parameters; detect an error during the startup operation; adjust at least one of the one or more default parameters in response to the detected error; store the at least one adjusted parameter in the memory; and commence subsequent startup operations based at least in part on the at least one adjusted parameter.

摘要： A connection apparatus for sealing to a pathway of a mounting structure includes a body; and a port including a threaded portion extending from the body and a non-threaded portion extending from the threaded portion, the non-threaded portion carrying a gasket, the gasket positioned along the non-threaded portion such that the mounting structure to which the connection apparatus is mounted contacts the gasket prior to the threaded portion engaging a mating threaded portion of the mounting structure, the port providing fluid communication between the body and the pathway of the mounting structure. The body may be that of a valve that supplies any of air, water or oil as an operating fluid to, for example, inlet and outlet valves and a pump chamber of a medical fluid pump of a medical fluid delivery machine.

摘要： A system for treating heart disease, such as pulmonary hypertension or right heart failure, including an implantable component and external components for monitoring the implantable component is provided. The implantable component may include a compliant member, e.g., balloon, coupled to a reservoir via a conduit. Preferably, the compliant member is adapted to be implanted in a pulmonary artery and the reservoir is adapted to be implanted subcutaneously. The external components may include a clinical controller component, monitoring software configured to run a clinician's computer, a patient monitoring device, and a mobile application configured to run on a patient's mobile device.

摘要： A catheter pump assembly is provided that includes a proximal a distal portion, a catheter body, an impeller, and a flow modifying structure. The catheter body has a lumen that extends along a longitudinal axis between the proximal and distal portions. The impeller is disposed at the distal portion. The impeller includes a blade with a trailing edge. The flow modifying structure is disposed downstream of the impeller. The flow modifying structure has a plurality of blades having a leading edge substantially parallel to and in close proximity to the trailing edge of the blade of the impeller and an expanse extending downstream from the leading edge. In some embodiments, the expanse has a first region with higher curvature and a second region with lower curvature. The first region is between the leading edge and the second region.

摘要： An implantable device for improving the pump function of the heart of a human patient by applying an external force on a first position of the heart muscle following the heart's contractions. The implantable device comprising a first pump device adapted to assist the pump function of the heart. The pump device comprises a first reservoir having a first volume and adapted to varying said first volume, a second reservoir having a second volume and adapted to varying said second volume, a fluid connection adapted to fluidly connect said first reservoir with said second reservoir, such that fluid can flow between said first reservoir and said second reservoir. The reservoir, said second reservoir and said fluid connection form a fully implantable pump device adapted to maintain a fluid in a closed system, when in operation and wherein said fully implantable pump device is adapted to transfer force by transferring fluid from said first reservoir to said second reservoir to directly or indirectly apply an external force on the first position of the heart muscle, following the heart's contractions, for improving the pump function of the heart, when said device is implanted. The implantable device further comprises a sensor sensing muscle contractions of the heart.
