Abstract: A stented valve including a generally tubular stent structure that has a longitudinal axis, first and second opposite ends, a plurality of commissure support structures spaced from the first and second ends and extending generally parallel to the longitudinal axis, at least one structural wire positioned between each two adjacent commissure support structures, and at least one wing portion extending from two adjacent commissure support structures and toward one of the first and second ends of the stent structure. The stewed valve further includes a valve structure attached within the generally tubular stent structure to the commissure support structures.

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.

Abstract: Selective sensing implantable medical leads include pulsing and sensing portions and pulsing and not sensing portion. Leads and electrodes may be used in defibrillation and as integrated bipolar defibrillation electrodes. An entire electrode can pass charge while a valve metal or valve metal oxide portion of the electrode prevents the entire electrode from sensing, effectively rejecting unwanted signals. Differential conduction pathways, due to the valve metal and/or oxides thereof, cause the portions of the electrodes to conduct differently when used anodically and cathodically. Complex intracardiac electrical gradient can be formed along with a number of virtual electrodes within the tissue. Reentrant loops can thereby be pinned following defibrillation shock.

Abstract: A compressible and expandable stent assembly for implantation in a body lumen such as a mitral valve, the stent assembly including at least one stent barrel that is shaped and sized so that it allows for normal operation of adjacent heart structures. One or more stent barrels can be included in the stent assembly, where one or more of the stent barrels can include a cylinder with tapered edge.

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.
