  • Patent number: 12337163
    Abstract: A circulatory support device includes a flexible cannula having a fluid outlet at a proximal end, and a pump assembly disposed at a distal end of the flexible cannula. The pump assembly includes a pump housing having a fluid inlet defined therein, a motor disposed within a distal end of the housing, and an impeller, driven to rotate by the motor, and configured to push blood toward the fluid outlet. A method of deploying the device to a subject's heart using an insertion manifold that prevents a protective tube from advancing with the device into a delivery shaft, is also disclosed. Pushing the device into and then out of the shaft expands and secures a cage at a location in the vasculature.

  • Publication number: 20230149670
    Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an elongate shaft having a proximal end region and a distal end region. A first lumen may be defined in the shaft. A second lumen may be defined in the shaft. The distal end region may include a common lumen region in fluid communication with the first lumen and the second lumen. A deflectable member may be disposed within the shaft. The deflectable member may be designed to shift between a first configuration where the deflectable member directs a first medical device disposed within the common lumen region into the first lumen and a second configuration where the deflectable member allows a second medical device to move between the common lumen region and the second lumen.
