Abstract: 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.

Abstract: The present invention is directed to a system for monitoring the functional status of an implantable heart valve. The system includes wireless pressure sensors that are embedded in the implantable heart valve. An external device receives signal transmitted from the wireless pressure sensors. The external device reads and analyzes these signals and then transmits the data to a healthcare provider.

Abstract: A passive implantable medical device for controlling a flow of fluid through a tube within a patient includes a first component and a second component movably coupled to one another and defining a central passage configured for receiving a portion of the tube therethrough. The passive implantable medical device is configured for moving between a first configuration and a second configuration to constrict a portion of the tube. An active implantable medical device for controlling a flow of a first fluid through a tubing includes a flow control cuff comprising a stiff outer wall and a deformable inner wall which defines a central opening sized such that the tubing can extend therethrough. A pump is configured to modulate a pressure of the second fluid within the interior space to apply a constrictive force to a section of the tubing.
