  • 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.

  • Publication number: 20200397574
    Abstract: Embodiments of the present disclosure provide a delivery apparatus for a prosthetic heart valve. Disclosed delivery apparatuses can include a housing, a steerable shaft, a slide nut, and a threaded shaft disposed over the slide nut. The slide nut can have an external threaded surface and an internal surface comprising a slot. The threaded shaft can have an internal threaded surface engaging the external threaded surface of the slide nut. The delivery apparatus can further include an elongated nut guide extending into the slot of the nut to restrain the slide nut against rotation relative to the housing, and a pull wire having a proximal end portion extending into the housing and coupled to the slide nut, and a distal end portion coupled to a distal end portion of the steerable shaft. The threaded shaft can be rotatable relative to the housing to produce axial movement of the slide nut within the threaded shaft.

  • Publication number: 20200060822
    Abstract: A method of delivery a prosthetic heart valve includes inserting a delivery apparatus and a prosthetic heart valve into a patient's vasculature. The delivery apparatus includes a steerable guide catheter, a balloon catheter, and a flex indicator. The balloon catheter extends coaxially through the guide catheter, the prosthetic heart valve is mounted on a distal end portion of the balloon catheter, and the flex indicator is movably coupled to a handle of the guide catheter. The method further includes adjusting flexion of a steerable section of the guide catheter to position the prosthetic heart valve. The flex indicator moves relative to the handle of the guide catheter as the flexion of the steerable section is adjusted, and the handle comprises one or more visual indicators adjacent the flex indicator to provide visual indication of an amount of flexion of the steerable section of the guide catheter.

  • Publication number: 20190328512
    Abstract: Pinch devices and access systems that can be used to secure a prosthetic heart valve to a heart valve annulus and to treat valvular insufficiency. A pinch device can be a separate expandable element from the prosthetic heart valve that is first advanced to the annulus and deployed, after which an expandable prosthetic heart valve can be advanced to within the annulus and deployed. The two elements can clamp/pinch the heart valve leaflets to hold the prosthetic heart valve in place. The pinch device can have a flexible, expandable annular frame. A combined delivery system can deliver the pinch device and prosthetic heart valve with just a single access point and aid more accurate coaxial deployment. The pinch device can be mounted near distal end of an access sheath, and a catheter for delivering the prosthetic heart valve can be passed through a lumen of the same access sheath.
