  • Patent number: 11253355
    Abstract: A prosthetic heart valve for functionally replacing a previously implanted prosthetic heart valve is disclosed. The prosthetic heart valve includes a collapsible support structure with leaflets and anchors mounted to the support structure. The support structure also includes an inflow end and an outflow end. The anchors include a radially outwardly extending first anchor proximate to the inflow end and a radially outwardly extending second anchor proximate to the outflow end. The first anchor includes a first configuration and the second anchor includes a second configuration where the first configuration is different than the second configuration. The previously implanted prosthetic heart valve serves as a platform for securement of the prosthetic heart valve to the patient's native tissue.

  • Patent number: 10335280
    Abstract: A method for treating a human patient includes emitting ultrasound energy from an ultrasound transducer positioned remotely from target tissue of the patient. The ultrasound transducer is positioned at a desired location relative to the patient and target tissue using location and imaging techniques. The method further includes focusing the ultrasound energy such that one or more focal points are directed to the target tissue of the patient and ablating the target tissue at each focal point. The target tissue is ablated via the focused ultrasound energy without ablating non-target tissue through which the ultrasound energy passes between the ultrasound transducer and the one or more focal points.

  • Patent number: 9949831
    Abstract: A method for determining whether a medical device is appropriate for implanting into a cardiovascular conduit of a patient is disclosed comprising imaging a first section of the conduit of the patient into which the medical device is to be implanted during a first expanded state occurring at a first portion of a heart rhythm; reimaging the first section of the conduit of the patient during a first contracted state occurring at a second portion of the heart rhythm; deriving, from the imaging and the reimaging, dimensional characteristics of the first section of the conduit; and determining whether the medical device is appropriate for implantation in the first section of conduit based on the derived dimensional characteristics. The first section of the conduit includes a sizing device providing a selected radial force on the patient.

  • Publication number: 20160302925
    Abstract: A method for valve replacement or valve repair is disclosed comprising the steps of acquiring an anatomical image of a patient, correlating the image to the patient, guiding a valve replacement delivery member or a valve repair delivery member within the patient while tracking the position of the delivery member in the patient, positioning the valve replacement member or valve repair member in a desired position to place a valve or repair valve and removing the delivery member from the patient. In one aspect, a method and device are provided that involve imaging a native root using an interoperative technique, then introducing a device that is easily visualized in a chosen imaging modality.

  • Patent number: 8591570
    Abstract: A method of functionally replacing a previously implanted prosthetic heart valve. The method includes positioning a replacement prosthetic heart valve within an internal region defined by the previously implanted prosthetic heart valve. The replacement prosthetic heart valve is then physically docked to the previously implanted prosthetic heart valve. With this technique, the previously implanted prosthetic heart valve serves as a platform for securement of the replacement prosthetic heart valve to the patient's native tissue.

  • Patent number: 8029564
    Abstract: A prosthetic heart valve system including a prosthetic heart valve and a deflection device. The deflection device includes a line and a connector assembly including a tensioning component. The line interconnects and passes through free ends of stent posts associated with the heart valve, and is further connected to the tensioning component. The tensioning component is transitionable to a tensioning state in which the line is tensioned to inwardly deflect the stent posts. In this regard, the tensioning component is self-locking relative to the line in the tensioning state, and an entirety of the line extending distal the tensioning device does not extend beyond a stent portion of the heart valve opposite the stent posts. In a preferred embodiment, a holder body is further included, coupled to the heart valve apart from the deflection device.

  • Patent number: 7637943
    Abstract: A method for evaluating a valve annulus to determine a size of a prosthetic heart valve to be sewn to the valve annulus during heart valve replacement surgery. The prosthetic heart valve includes an annular extension having a first flexibility and a sewing ring having a second flexibility. A flexible sizer body is provided and includes an outer ring and an annular wall coupled to and extending from the outer ring. The annular wall has a flexibility substantially similar to the first flexibility of the annular extension of the prosthetic heart valve. The flexible sizer body is inserted into the valve annulus and a determination made as to fit and conformance. A prosthetic heart valve is selected based on the determination.

  • Patent number: 7468073
    Abstract: A valve system including an aortic valve and a holder. The holder includes a holder body, which has a central portion, engagable with a holder handle, and downwardly extending leg portions that engage the valve in the areas between the commissure posts. The central portion of the holder further includes a spool located between the commissure posts, rotatable by an attached handle. Rotation of the spool draws in a tensile member passing through the commissure posts, drawing the commissure posts inward toward the spool. The tensile member passes through guides formed in the holder, configured such that they define the maximum available inward deflection of the commissure posts at the point at which the portions of the tensile member between the commissure posts assume straight configurations.
