Abstract:
A prosthetic heart valve (e.g., a prosthetic aortic valve) is designed to be somewhat circumferentially collapsible and then re-expandable. The collapsed condition may be used for less invasive delivery of the valve into a patient. When the valve reaches the implant site in the patient, it re-expands to normal operating size, and also to engage surrounding tissue of the patient. The valve includes a stent portion and a ring portion that is substantially concentric with the stent portion but downstream from the stent portion in the direction of blood flow through the implanted valve. When the valve is implanted, the stent portion engages the patient's tissue at or near the native valve annulus, while the ring portion engages tissue downstream from the native valve site (e.g., the aorta).

Application number: 17/507,268

Abstract:
A system and method are provided for determining a pressure associated with a lumen of a body. A wireless sensor is positioned in the lumen of the body. The sensor comprises an LC resonant circuit having a resonant frequency configured to vary in response to changes in pressure in the lumen. One or more sensor calibration parameters are stored at an external base unit. The external based unit generates and transmits an energizing signal. A ring down response is received from the wireless sensor. The system and method determine the resonant frequency of the LC resonant circuit from the ring down response and calculate the pressure in the lumen from the resonant frequency of the LC resonant circuit utilizing the one or more sensor calibration parameters associated with the LC resonant circuit.

Application number: 17/481,845

Abstract:
In various embodiments, a catheter comprising an expandable electrode assembly or basket is provided. In specific embodiments, the basket is particularly useful for mapping electrical activity at one or more locations within the heart. The basket can comprise a plurality of bendable or deflectable arms. At least one of the arms may have varied flexibility over its length in the form of one or more discontinuities of stiffness or flexibility at an elbow region or other variances in flexibility over the arm's length. Such variance in flexibility may allow the arm to assume a different bent configuration or respond to external factors more positively than possible with an arm having a static or near static flexibility or stiffness over its length.
