Catheter blood pumps that include an expandable pump portion. The pump portions include an collapsible blood conduit that defines a blood lumen. The collapsible blood conduits include a collapsible scaffold adapted to provide radial support to the blood conduit. The pump portion also includes one or more impellers.

Catheter blood pumps and collapsible pump housings

Catheter blood pump that include an expandable pump portion extending distally from an elongate shaft. The pump portions include an expandable impeller housing including an expandable blood conduit that defines a blood lumen between an inflow and an outflow. The pump portions include one or more expandable impellers disposed at least partially within the blood lumen.

Intravascular blood pumps and methods of manufacture and use

Intravascular blood pumps and methods of use. The blood pump include a pump portion that includes a collapsible blood conduit defining a blood flow lumen between an inflow and an outflow. The pump portion includes a distal collapsible impeller axially spaced from a proximal collapsible impeller, at least a portion of each of the distal and proximal collapsible impellers disposed between the inflow and the outflow.

Intravascular blood pumps and methods of use

Catheter blood pumps that include an expandable pump portion, which include an expandable impeller housing. The housings include an expandable blood conduit that defines a blood lumen, and one or more pluralities of expandable struts extending axially from an end region of the expandable blood conduit. At least one of the pluralities of struts are non-unitary with a blood conduit at the end region.

Intravascular blood pumps with struts and methods of use and manufacture

Catheter blood pumps that include an expandable pump portion. The pump portions include a collapsible blood conduit that defines a blood lumen. The collapsible blood conduits include a collapsible scaffold adapted to provide radial support to the blood conduit. The pump portion also includes one or more impellers.

Apparatus for endovascularly replacing a patient's heart valve, including: a replacement valve adapted to be delivered endovascularly to a vicinity of the heart valve; an expandable anchor adapted to be delivered endovascularly to the vicinity of the heart valve; and a lock mechanism configured to maintain a minimum amount of anchor expansion. The invention also includes a method for endovascularly replacing a patient's heart valve. In some embodiments the method includes the steps of: endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve; expanding the anchor to a deployed configuration; and locking the anchor in the deployed configuration.

Replacement valve and anchor

The invention includes methods of and apparatus for endovascularly replacing a heart valve of a patient. One aspect of the invention provides a method including the steps of endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve in an unexpanded configuration; and applying an external non-hydraulically expanding or non-pneumatically expanding actuation force on the anchor to change the shape of the anchor, such as by applying proximally and/or distally directed force on the anchor using a releasable deployment tool to expand and contract the anchor or parts of the anchor. Another aspect of the invention provides an apparatus including a replacement valve; an anchor; and a deployment tool comprising a plurality of anchor actuation elements adapted to apply a non-hydraulically expanding or non-pneumatically expanding actuation force on the anchor to reshape the anchor.

Methods and apparatus for endovascularly replacing a heart valve

A replacement heart valve commissure assembly may include a locking mechanism including a first locking portion spaced apart from a second locking portion in a delivery configuration and configured to engage with the second locking portion in a deployed configuration, wherein the first locking portion is longitudinally actuatable relative to the second locking portion between the delivery and deployed configurations. The commissure assembly may include a first valve leaflet and a second valve leaflet each secured to the first locking portion. A first sleeve portion of the first valve leaflet may be fixedly attached to a first fabric sleeve wrapped around a first leg of the first locking portion by a first filament, and a second sleeve portion of the second valve leaflet may be fixedly attached to a second fabric sleeve wrapped around a second leg of the first locking portion by a second filament.

Replacement heart valve commissure assembly

Medical devices and delivery systems for delivering medical devices to a target location within a subject. In some embodiments the medical devices can be locked in a fully deployed and locked configuration. In some embodiments the delivery systems are configured with a single actuator to control the movement of multiple components of the delivery system. In some embodiments the actuator controls the independent and dependent movement of multiple components of the delivery system.
