Abstract
An electrical-component add-on is provided for use with a prosthetic cardiac valve including a tubular frame. The electrical-component add-on includes a support and one or more electrical components. The support is (a) configured to assume delivery and deployed configurations, (b) configured to be positioned above, at, or below an annulus of a native cardiac valve of a heart, and (c) shaped as a ring when in the deployed configuration, so as to receive the tubular frame of the prosthetic cardiac valve within the support. The one or more electrical components are supported by the support, and include an antenna and one or more electrodes. Other embodiments are also described.
Claims24
A method comprising:
- advancing a support of an electrical-component add-on to a native cardiac valve of a heart of a patient while the support is in a delivery configuration and the electrical-component add-on is disposed within a delivery sheath, the electrical-component add-on further including one or more electrical components, which are supported by the support, and which include an antenna and one or more electrodes, wherein the support includes a tubular stent that (a) comprises interconnected stent struts and (b) is self-expandable and not balloon-expandable;
- positioning the support above, at, or below an annulus of the native cardiac valve and transitioning the support from the delivery configuration to a deployed configuration in which the support is shaped as a ring, by releasing the electrical-component add-on from the delivery sheath such that the tubular stent self-expands;
- and
- thereafter, introducing a prosthetic cardiac valve into a body of the patient and placing a tubular frame of the prosthetic cardiac valve within the support, wherein the prosthetic cardiac valve includes a plurality of prosthetic leaflets coupled to the tubular frame so as to allow blood flow in a proximal downstream direction and inhibit blood flow in a distal upstream direction.
A method comprising:
- advancing a support of an electrical-component add-on to a native cardiac valve of a heart of a patient while the support is in a delivery configuration, the electrical-component add-on further including one or more electrical components, which are supported by the support, and which include an antenna and one or more electrodes;
- positioning the support above, at, or below an annulus of the native cardiac valve using one or more elongate deployment members of a delivery system to hold the support above, at, or below the annulus while the one or more elongate deployment members are reversibly coupled to the support, and while a tubular frame of a prosthetic cardiac valve is unconnected to the support, and transitioning the support from the delivery configuration to a deployed configuration in which the support is shaped as a ring;
- thereafter, introducing the prosthetic cardiac valve into a body of the patient and placing the tubular frame of the prosthetic cardiac valve within the support while the one or more elongate deployment members are reversibly coupled to the support, wherein the prosthetic cardiac valve includes a plurality of prosthetic leaflets coupled to the tubular frame so as to allow blood flow in a proximal downstream direction and inhibit blood flow in a distal upstream direction;
- and
- decoupling the one or more elongate deployment members from the support after placing the tubular frame within the support.
