Methods for determining likelihood of thrombosis based on patient-specific anatomic, valve, and flow parameters are disclosed herein. Such methods are used to select a transcatheter aortic valve that decreases likelihood of thrombosis after TAVR procedures. The methods correlate a number of fluid flow and geometric parameters such as stasis volume, neo-sinus volume, kinematic viscosity, dynamic viscosity, heart rate, the circulation, ejection time, velocity of the main jet, wall shear stress, total kinetic energy in the neo sinus volume, width of the neo-sinus, height or depth of the neo-sinus, the angle between the velocity direction and the stent of the transcatheter valve, the distance from the tip of the leaflet perpendicular to the leaflet edge and intersecting the sinotubular junction, and the cross-sectional area of the neo-sinus taken from a longitudinal or axial perspective. Such parameters are used to derive empirical or semi-empirical mathematical models to determine the likelihood of thrombosis.

Systems and methods for predicting thrombosis for heart valve replacements

Various embodiments of the present invention provide a conduit system including an outer lumen, an inner lumen, and an attaching device. In other embodiments, a multiple access port device adapted for communication with at least one of an outer lumen, an inner lumen, or an attaching device of a conduit system is provided. In yet other embodiments, a system including an inner lumen that is collapsible is provided. Means for closing a conduit system are also provided, including a plug for insertion through an attaching device and a variable radius coiled member associated with an attaching device.

Systems for implanting and using a conduit within a tissue wall

The devices and methods relate to surgical and percutaneous repair of heart valve regions. The devices may be structured to conform to the desired shape of a specific patient. The devices may include a frame and an artificial body onto which leaflets of the valve may coapt or rest.

Devices and methods for surgical and percutaneous repair of heart valve lesions

Various embodiments of the present invention provide a conduit system including an outer lumen (), an inner lumen (), and an attaching device (). In other embodiments, a multiple access port device adapted for communication with at least one of an outer lumen, an inner lumen, or an attaching device of a conduit system is provided. In yet other embodiments, a system including an inner lumen that is collapsible is provided. Means for closing a conduit system are also provided, including a plug for insertion through an attaching device and a variable radius coiled member associated with an attaching device.

An annuloplasty ring, configured for implantation in the annulus of a heart valve, comprising multiple segments each of which are geometrically shaped from a three dimensional perspective to conform to the anatomic shape of the valve annulus. In one embodiment, at least one of the multiple segments of the annuloplasty ring is configured to facilitate a reduction of tension on heart valve tissue and eliminate a substantial portion of potential pressure or force that may be applied to the atrio-ventricular node by the annuloplasty ring when inserted into a heart valve. In another embodiment, at least one of the multiple segments of the annuloplasty ring are configured to include an assembly that facilitates selective adjustment of a segment's respective length and/or shape. The adjustment of the length of one of the ring segment's results in an adjustment of at least one angle between at least one set of other ring segments, thereby causing an adjustment to the geometric characteristics of the ring.
