  • Patent number: 11172921
    Abstract: A heart valve anchor has a body that includes a distal portion, a distal end, a proximal portion, and a proximal end. The distal end and the proximal end define a longitudinal axis. The body has an expandable portion that includes a first radially expandable portion at the distal portion of the body, a second radially expandable portion at the proximal portion of the body, and a root portion disposed between the first and second radially expandable portions. The body has a first configuration adapted to be housed at least partially within a tissue penetrating device, and a second configuration in which the first and second radially expandable portions are partially or fully expanded such that the anchor engages tissue in a region between the first and second radially expandable portions.

  • Publication number: 20160220357
    Abstract: Devices provided herein can include implantable transseptal flow control components adapted to be implanted in an opening in a septal wall. In a closed configuration, the implantable transseptal flow control components provided herein prevent blood from flowing through the opening. In an open configuration, the implantable transseptal flow control components provided herein allow blood to flow from the left atrium to the right atrium. In a closed configuration, implantable transseptal flow control components provided herein can be configured such that blood does not stagnate at a location proximate to a left atrium flow control component side when the pressure differential is below a second predetermined threshold pressure value. Implantable transseptal flow control components provided herein can remain in a closed configuration when a pressure differential between the left atrium and the right atrium is less than a first non-zero predetermined threshold pressure value.

  • Publication number: 20150360009
    Abstract: Multifunctional occlusion crossover devices include features to improve the crossover balloon occlusion technique used during transcatheter aortic valve replacement procedures, for example. The devices include a compliant balloon incorporated with a highly flexible and lubricous sheath system. The balloon is capable of safely occluding from the common iliac artery and down to an access site in the femoral artery. The devices can simplify the CBOT technique and replace multiple devices currently used for the procedure.
