  • Patent number: 10959848
    Abstract: A pair of paddles are moved laterally away from one another in an exemplary method of repairing a native valve of a patient during a non-open-heart procedure. After the paddles are moved laterally away from one another, first and second gripping members are moved from an open position to a closed position to grasp valve leaflets. The paddles are then moved laterally toward one another. A cam can be used to move the paddles away from one another.

  • Patent number: 10940000
    Abstract: A delivery catheter is in various embodiments configured to deliver an anchoring device to a native valve annulus of a patient's heart, where the anchoring device can better secure a prosthesis at the native annulus. The delivery catheter can includes a distal section that includes one or more spines or is laser cut to assume a particular shape for better facilitating delivery of the anchoring device at the implant site and can include a flexible tube, a first pull wire, and a second pull wire. The flexible tube can comprise a bore extending between the first end and the second end sized for passing the anchoring device therethrough. The distal portion can comprise a first flexing section and a second flexing section. Actuation of the first pull wire and the second pull wire can cause the flexible tube to move from a first configuration to a second configuration.

  • Patent number: 10925734
    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.

  • Publication number: 20210030540
    Abstract: Embodiments of the present disclosure provide an introducer device and method for introducing a delivery apparatus into a patient's vasculature. Disclosed methods can include positioning a sleeve of an introducer sheath in a blood vessel of a patient, the sleeve having a lattice layer with a lumen therethrough, inserting a distal end portion of the delivery apparatus and a prosthetic heart valve into the lumen, and advancing the distal end portion of the delivery apparatus through the lumen from the proximal end to the distal end. The method can then include expanding the lumen from a first diameter smaller to a second diameter at least equal to the diameter of the prosthetic heart valve to allow passage of the prosthetic heart valve through the lumen, and returning the lumen of the sleeve to a diameter smaller than the second diameter after advancing the prosthetic heart valve through the lumen.
