Abstract
Embodiments of a prosthetic valve delivery apparatus are disclosed. The delivery apparatus can include an indicator arm changeable between a first configuration and a second configuration. The second configuration is different from the first configuration in location or shape of the indicator arm. The indicator arm can be configured to remain in the first configuration when a diameter of the prosthetic valve is smaller than a first predetermined size, and change to the second configuration when the diameter of the prosthetic valve is expanded to the first predetermined size.
Claims18
A delivery apparatus configured to provide visual feedback of radial expansion of a prosthetic valve, the delivery apparatus comprising:
- an indicator arm changeable between a first configuration and a second configuration, the second configuration being different from the first configuration in location or shape of the indicator arm;
- wherein the indicator arm is configured to remain in the first configuration when a diameter of the prosthetic valve is smaller than a first predetermined size, and change to the second configuration when the diameter of the prosthetic valve is expanded to the first predetermined size;
- and
- a first actuation component and a second actuation component that are configured to interface with an expansion mechanism of the prosthetic valve such that axially moving the second actuation component relative to the first actuation component in a first direction causes the prosthetic valve to expand from a radially compressed state to a radially expanded state, and axially moving the second actuation component relative to the first actuation component in a second direction opposite the first direction causes the prosthetic valve to compress from the radially expanded state to the radially compressed state.
A delivery apparatus configured to provide visual feedback of radial expansion of a prosthetic valve, the delivery apparatus comprising:
- an indicator arm moveable between a biased position and an unbiased position;
- wherein the indicator arm is configured to remain in the biased position when a diameter of the prosthetic valve is smaller than a first predetermined size, and move to the unbiased position when the diameter of the prosthetic valve is expanded to the first predetermined size;
- and
- a first actuation component and a second actuation component that are configured to interface with an expansion mechanism of the prosthetic valve such that axially moving the second actuation component relative to the first actuation component causes radial expansion or compression of the prosthetic valve.
