  • Patent number: 11311397
    Abstract: An iliac branch device has an external iliac body, a common iliac branch, and an internal iliac branch. A diameter of the proximal opening of the common iliac branch is greater than a diameter of a distal opening of the external iliac body. The iliac branch device is configured to be deployed without going up and over the aortic bifurcation and without using some form of supra-aortic antegrade access such as through brachial or axillary artery access. This simplifies the procedure and reduces procedure time thus maximizing the success rate of the procedure and allows the procedure to be performed on a broad patient population.

    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.

  • Patent number: 11234816
    Abstract: In a particular embodiment, the present disclosure provides a delivery apparatus for delivering a medical device. The delivery apparatus includes an elongated component with an engagement portion and a disengagement portion. Rotating the elongated component in a first rotational direction moves the travelling component along the engagement portion in a first axial direction. When the travelling component is located within the disengagement portion, continued rotation of the elongated component in the first rotational direction does not cause further movement of the travelling component in the first axial direction. A biasing member is located proximate the disengagement portion and urges the travelling component to reengage the engagement portion. The delivery apparatus can reduce or prevent damage to the delivery apparatus, or a patient with whom the delivery apparatus is used, by reducing or eliminating torque transfer from the travelling component to an end of the elongated component.

  • Patent number: 11220059
    Abstract: 2-manifold structures are structures having continuously curvilinear surfaces, with no kinks or sharp angles. Methods for building strong, lightweight 2-manifold structures include a computer implemented strength optimization process. The computer implemented process includes a structure optimization sub-routine in which a plurality of rod-like members, constituting an irregular scaffold, is constrained into a volume corresponding to the 2-manifold structure. The strength of the irregular scaffold is then optimized by application of an algorithm that maximizes strength as a function of variations in the ratio of the largest macroscopic dimension of the panel to the average length of the members; the aspect ratio of the members (diameter divided by length); the average or maximum number of times a member can contact another member; and the distribution of member lengths. Strength maximization can be simultaneous to minimization of total length of the members.

The proximal end portion can be coupled to the handle and the distal end portion can be releasably coupled to the prosthetic heart valve. The delivery apparatus can also have a delivery sheath and a hydraulic power source operatively connected to the delivery sheath. The prosthetic heart valve can be positioned within the delivery sheath in a radially compressed state. The hydraulic power source can be configured to move the delivery sheath longitudinally relative to the valve to allow the valve to self-expand from the radially compressed state to a radially expanded state.

  • Patent number: 11096811
    Abstract: A handle for an implant deployment device converts rotational movement into longitudinal movement in order to provide controlled release of one or more trigger wires. The handle also allows the trigger wire to be withdrawn into the device so that it does not need to be separately removed. A preferred handle includes a rotatable portion and a slidable portion. Releasable locks ensure that the handle is used to carry out implant deployment steps in a specific order.

    Abstract: Various features and associated advantages are described for diametrically adjustable support structures, adjustable valve structures, removable/replaceable valve structures, and associated systems and methods. Although some examples are directed toward prosthetic valve that is a conduit having a valve structure, or a “valved conduit” (e.g., used to replace a pulmonary valve and a portion of the corresponding pulmonary artery or an aortic valve and the aortic root), and other examples are directed toward prosthetic valves implanted native valve orifices (e.g., to replace an aortic or mitral valve), the features and advantages of the structures associated with those examples are interchangeable regardless of a particular application for which the examples are described.

  • Patent number: 11071638
    Abstract: An implantation method of a stent system, and the implantation method including implanting a main stent; introducing a catcher; introducing a long sheath and a guiding catheter along a preset guide wire, so as to make the distal end of the long sheath and the distal end of the guiding catheter extend out from the distal end of the inner branch; the distal end of the long sheath and the distal end of the guiding catheter to respectively enter a target branch blood vessel; withdrawing the guiding catheter, and introducing a branch stent delivery along the long sheath to complete the implantation of the branch stent. The method greatly shortens the implantation time of the stent system by simplifying the path of the preset guide wire in the implantation process and fully utilizing the characteristics of the preset guide wire with double soft heads.
