摘要： A medical device may include an insertion device having a proximal end, a distal end, and a lumen extending therethrough. The medical device may further include a snare device configured to transition between a contracted state within the lumen of the insertion device, and an expanded state extending distally of the insertion device. The snare device may include a loop including a pair of legs and a distal tip. The distal tip may include a plurality of stabilizers between the pair of legs.

摘要： A medical device may include an insertion device having a proximal end, a distal end, and a lumen extending therethrough. A snare device may be configured to transition between a retracted state within the lumen of the insertion device, and an extended state extending distally of the insertion device. The snare device may comprise a wire. A member may be disposed within the lumen of the insertion device. The member may be configured to maintain legs of the snare device in an open snare loop configuration in the extended state. In the open snare loop configuration, the wire may include an arcuate loop.

摘要： Various aspects of the present disclosure are directed towards apparatuses, systems, and methods that system for delivering a blood pump. The system may include a blood pump that may include one or more impellers configured to cause blood to flow through the pump. The system may also include one or more guidewires. The guidewires may include one or more proximal sections and one or more distal sections, and the distal sections may have first dimensions and the proximal sections may have second dimensions, and the first dimensions may be greater than the second dimensions. The guidewires may also be tapered, geometrically shaped, have a curved profile, a combination thereof, or other configurations.

摘要： Various aspects of the present disclosure are directed towards apparatuses, systems, and methods that may include a blood pump. The blood pump may include a magnetic field source and an impeller assembly. The impeller assembly includes an impeller and a driven magnet. The driven magnet is longitudinally offset and distally disposed relative to the magnetic field source, and the driven magnet is rotatable and longitudinally controlled by the magnetic field source. The driven magnet includes a distal side, the distal side faces the impeller. The blood pump further includes a bearing assembly near the distal side of the driven magnet.

摘要： A percutaneous circulatory support device includes a housing having an inlet and an outlet. A shaft is rotatably fixed relative to the housing. An impeller is disposed within the housing and is rotatably supported by the shaft. The impeller is configured to rotate relative to the shaft and the housing to cause blood to flow into the inlet, through the housing, and out of the outlet. A keeper is coupled to the shaft distally relative to the impeller, and the keeper inhibits axial motion of the impeller relative to the shaft.
