  • Patent number: 10561496
    Abstract: Disclosed herein are designs for improved inflatable structures for use during minimally invasive cardiovascular procedures. These inflatable structures facilitate the perfusion of blood through an anatomical structure, such as a heart valve, during the cardiovascular procedure. The inflatable structures are formed of a plurality of balloons arranged radially around a central location. The plurality of balloons form a lumen through which blood flows. Each balloon of the plurality is shaped or configured to stabilize the adjacent balloons, limiting their movement relative to each other. For example, some embodiments can feature balloons with a keystone shape that limits movement of the balloons inward toward the lumen. Some implementations can also include a support coil running through the lumen. The support coil holds enables the lumen to be open to perfusion even in the early stages of balloon inflation.

  • Patent number: 10463481
    Abstract: A prosthetic heart valve includes a collapsible and expandable frame having a main body, an atrial portion, and at least one ventricular anchor. The atrial portion extends radially outwardly relative to the main body and the ventricular anchor extends from a ventricular end of the main body. The main body and the atrial portion are preferably separate metal components that are coupled together via sutures or a fabric member. The prosthetic heart valve also includes a valve structure that is supported in the main body of the frame. The valve structure has a plurality of leaflets for regulating the flow of blood in one direction.

  • Publication number: 20190298518
    Abstract: A method of implanting a prosthetic heart valve includes advancing a distal end portion of a catheter shaft through a patient's vasculature. The distal end portion of the catheter shaft includes an expansion device. A prosthetic heart valve is mounted on the expansion device with the expansion device and the prosthetic heart valve in a compressed configuration. The method further includes positioning the distal end portion of the catheter shaft and the prosthetic heart valve to an implantation location, and expanding the prosthetic heart valve and the expansion device from the compressed configuration to an expanded configuration. The expansion device includes an inner expandable member and a plurality of outer expandable members. The outer expandable members are distributed such that there are gaps providing perfusion passageways between the expansion device and the prosthetic heart valve when the expansion device is in the expanded configuration.

  • Publication number: 20190060073
    Abstract: An exemplary valve repair device is released from tissue of a valve of a patient by applying tension to a movable arm of a clasp in a retraction direction. A fixed arm of the clasp is attached to an inner paddle portion of a paddle of the valve repair device. The inner paddle portion is connected to an outer paddle portion of the paddle of the valve repair device. Pulling the moveable arm of the clasp flexes the inner paddle portion to allow the moveable arm to move in the retraction direction and thereby release the clasp from the valve tissue.

  • Publication number: 20190021852
    Abstract: An exemplary valve repair device for repairing a native valve of a patient includes a coaption element, a collar, a pair of paddles, a cap, and a shaft. The coaption element has a first end portion and a second end portion. The collar is connected to the first end portion of the coaption element. The pair of paddles each include an inner paddle portion and an outer paddle portion that are movable between an open position, a closed position, and a bailout position. The cap is connected to the pair of paddles. The shaft extends through the collar and the coaption element and is connected to the cap. Movement of the cap by the shaft causes the inner paddle portions and the outer paddle portions of the pair of paddles to move between the open position, the closed position, and the bailout position. When the paddles are in the bailout position, a bailout angle between each inner paddle portion and the shaft is greater than or equal to 120 degrees.
