  • Patent number: 10842476
    Abstract: A method of treating a heart includes radially expanding a housing component within a native atrioventricular valve. The housing component includes an atrial anchoring mechanism for deployment in the left atrium and ventricular prongs for engagement with native tissue in the left ventricle. The housing component also includes an interior passageway sized for receiving a valve component. After the housing component has been deployed, the valve component is radially expanded within the passageway of the housing component. The valve component includes three leaflets configured for allowing blood to flow from the left atrium to the left ventricle. After expansion within the housing component, the valve component may have an inflow end portion that protrudes above the housing component into the left atrium. The housing component and valve component are preferably collapsible for advancement through a patient's vasculature using one or more catheters.

  • Publication number: 20200201609
    Abstract: Disclosed herein are system, method, and computer program product embodiments for using design-time metadata to dynamically determine properties and actions for user-interface elements. By dynamically determining the properties and actions using the design-time metadata, a design-time tool may remain generic and need not include actual change handlers to process the actions and change the properties. By maintaining its agnosticism, a design-time tool may incorporate any changes to an overarching application framework without requiring code updates to the design-time tool itself.

  • Publication number: 20200129739
    Abstract: Some embodiments are directed to a catheter system comprising an introducer having a main body, an introducer sheath projecting from the main body, and a first seal supported within the introducer and a catheter having a main body, an outer sheath projecting from the main body, a second seal supported within the catheter, and an inner core configured to be advanced axially through the main body, the second seal, and the outer sheath. The introducer can be configured to be selectively engageable with the catheter so that the catheter can be selectively and removably linked with the introducer in the axial direction. The catheter system can also be configured such that, when the introducer and the catheter are linked, the catheter can be rotatable relative to the introducer. The introducer can be configured to radially restrain an endoluminal prosthesis.

  • Publication number: 20190374225
    Abstract: Methods for treatment of aneurysms using a sequential manifold console to deploy multiple filling structures are provided herein. In one aspect, aneurysms are treated by simultaneously filling two double-walled filling structure using a sequential manifold console to guide a user in the steps to be followed in the procedure and to reliably achieve a consistent and durable aneurysmal treatment using a curable medium. The structures may be delivered over balloon deployment mechanisms in order to shape and open tubular lumens therethrough. Pairs of filling structures delivered to the aneurysm from different access openings of a patient can be simultaneously prepared and pressurized from a single treatment console when treating abdominal aortic aneurysms using the described systems and methods.

  • Publication number: 20190167856
    Abstract: A method for forming a material in an in situ medical device by initiating polymerization of water soluble polymer precursors in an aqueous solution during or after transport of the polymerizable solution from its storage container to a space inside the in situ medical device is described. The stored aqueous solution with water soluble precursors lacks a free radical initiator which, in a powder form, is introduced into the aqueous solution during or after its transport into the space inside the in situ medical device. This storage and delivery system provides greater stability to the stored aqueous solution, allowing it to be stored at ambient temperature and providing extended shelf life over the solutions used in existing in situ polymerization systems. The flexibility to store and deliver/transport only one aqueous solution, instead of requiring the use of two different solutions, is also a benefit.

  • Patent number: 10188518
    Abstract: An annuloplasty ring having a three-dimensional discontinuous form generally arranged about an axis with two free ends that are axially offset. The ring is particularly suited for repair of the tricuspid valve, and more closely conforms to the annulus shape. The ring is more flexible in bending about radially extending axes than about the central axis. The ring may have an inner structural support covered by a pliable sleeve and/or a fabric tube. The structural support may have a varying cross-section, such as a C-shaped cross-section in a mid-section between two free ends and a rectangular cross-section at the free ends. A deliver template having a mounting ring with about the same shape as the ring facilitates implant, and may be releasably attached to a delivery handle. The deliver template may include a plurality of cutting guides for releasably attaching the annuloplasty ring thereto while presenting maximum outer surface area of the ring.
