  • Publication number: 20250058124
    Abstract: A prosthetic cardiac valve includes a frame and plurality of prosthetic leaflets coupled to the frame so as to allow blood flow in one direction. An antenna is mechanically coupled to the frame, and includes a magnetic core and one or more coils wound about the magnetic core. At at least one location along a length of the magnetic core, a planar space bound by an outer perimeter of the magnetic core, in a plane perpendicular to a central longitudinal axis of the frame, has (a) a shorter dimension, which is measured along a ray that radiates radially outward from the central longitudinal axis and intersects a centroid defined by the planar space, and (b) a longer dimension, which is measured perpendicular to the shorter dimension in the plane, and is at least 150% of the shorter dimension. Other embodiments are also described.

  • Patent number: 11975203
    Abstract: A prosthetic aortic valve is provided including a frame including interconnected stent struts arranged so as to define interconnected stent cells. A plurality of prosthetic leaflets are coupled to the frame so as to allow blood flow in a downstream direction and inhibit blood flow in an upstream direction when the prosthetic aortic valve is in an expanded deployment configuration. Circuitry is mechanically coupled to the frame. An electrode is mechanically coupled to the frame. A printed circuit board (PCB) is shaped so as to define an elongate portion. An electrical lead electrically couples the electrode to the circuitry, and is integral with the elongate portion of the PCB. The elongate portion of the PCB is mechanically coupled to some of the interconnected stent struts of the frame. Other embodiments are also described.

  • Patent number: 11931255
    Abstract: A prosthetic aortic valve is provided including a frame including interconnected stent struts arranged so as to define interconnected stent cells. Upstream ones of the stent cells are located in an upstream half of the frame and define respective upstream peaks. An electrode is disposed at or near an upstream peak of one of the upstream stent cells. First and Second upstream stent struts of the one of the upstream stent cells are joined at the upstream peak. Coupling material is shaped so as to define a first strip that is mechanically coupled to the first upstream stent strut, a second strip that is mechanically coupled to the second upstream stent strut, and a junction, which couples together the first and the second strips, such that the first and the second strips together couple the electrode to the frame at or near the upstream peak. Other embodiments are also described.

  • Patent number: 11291844
    Abstract: A prosthetic aortic valve is provided, which is configured to be delivered to a native aortic valve of a patient in a constrained delivery configuration within a delivery sheath. The prosthetic aortic valve includes a frame, which includes interconnected stent struts arranged so as to define interconnected stent cells; a plurality of prosthetic leaflets coupled to the frame; a cathode and an anode, which are mechanically coupled to the frame; and a prosthetic-valve coil, which is in non-wireless electrical communication with the cathode and the anode, and is coupled to a plurality of the stent struts, running along the stent struts so as to surround a plurality of the stent cells when the prosthetic aortic valve is in an expanded fully-deployed configuration upon release from the delivery sheath. Other embodiments are also described.

  • Patent number: 11065451
    Abstract: A prosthetic aortic valve is configured to be delivered to a native aortic valve of a patient in a constrained delivery configuration within a delivery sheath. The prosthetic aortic valve includes a frame; a plurality of prosthetic leaflets coupled to the frame; a cathode and an anode, which are mechanically coupled to the frame; and a prosthetic-valve coil, which is coupled to the frame and is in non-wireless electrical communication with the cathode and the anode. When the prosthetic aortic valve is in an expanded fully-deployed configuration upon release from the delivery sheath, (a) a line defined between upstream-most and downstream-most points of mechanical coupling between the prosthetic-valve coil and the frame and (b) a central longitudinal axis defined by the frame form an angle of between 20 and 70 degrees. Other embodiments are also described.

  • Patent number: 11013597
    Abstract: A valve prosthesis system includes a prosthetic aortic valve and a non-implantable unit. The prosthetic aortic valve includes a plurality of prosthetic leaflets; a frame; a cathode and an anode, which are mechanically coupled to the frame; and a prosthetic-valve coil, which is in non-wireless electrical communication with the cathode and the anode. The prosthetic aortic valve does not include any active electronic components. The non-implantable unit includes an energy-transmission coil; sensing skin ECG electrodes; and non-implantable control circuitry, which drives the cathode and the anode to apply a pacing signal to a heart, detect at least one cardiac parameter using the sensing skin ECG electrodes, and, at least partially responsively to the detected cardiac parameter, to set parameters of the pacing signal, by wirelessly transferring energy from the energy-transmission coil to the prosthetic-valve coil by inductive coupling. Other embodiments are also described.
