Prosthetic cardiac valve sensor devices, systems, and methods with imaging
A method for treating a diseased native valve in a patient includes advancing a distal end of a delivery device that is detachable coupled to an anchor to a first side of a native valve, deploying the anchor from a delivery configuration to a deployed configuration on the first side of the native valve, advancing the anchor in the deployed configuration from the first side of the native valve to a second side of the native valve such that the anchor is located only on the second side of the native valve, rotating the anchor in the deployed configuration around chordae of the native valve, confirming a position of the anchor with an imaging source, and releasing the anchor from the distal end of the delivery device.
1 . A prosthetic cardiac valve device for treating a diseased native valve of a heart, the device comprising:
a frame structure having a compressed configuration and an expanded configuration;
a spiral anchor configured to be positioned around the frame structure, the spiral anchor configured to anchor the frame structure to the native valve; and
an image capture device comprising a camera, the image capture device attached to or positioned within the spiral anchor and configured to confirm placement of the spiral anchor within the heart.
2 . The device of claim 1 , wherein the spiral anchor is configured to be fully advanced in the expanded configuration from an atrium of the heart through the native valve and into a ventricle of the heart.
3 . The device of claim 1 , wherein the camera is disposed within an inflatable membrane filled with an inflation fluid.
4 . The device of claim 3 , wherein the membrane is porous.
5 . The device of claim 4 , wherein the membrane is configured to diffuse saline therethrough.
6 . The device of claim 1 , wherein the image capture device is coupled to an external surface of the spiral anchor.
7 . The device of claim 1 , wherein the image capture device is positioned within a central lumen of the spiral anchor.
8 . The device of claim 1 , wherein the image capture device is coupled to a distal free end of the spiral anchor.
9 . The device of claim 1 , wherein image capture device comprises a plurality of sensors disposed along a length of the spiral anchor.
10 . The device of claim 9 , wherein the plurality of sensors comprise an impedance sensor.
11 . The device of claim 9 , wherein the plurality of sensors comprise a pressure sensor.
12 . The device of claim 9 , wherein the plurality of sensors comprise a radiopaque element.
13 . The device of claim 1 , wherein a distal free end of the spiral wire is configured to extend radially outward from a circumference of the spiral wire when the spiral wire is positioned around the frame structure.
14 . The device of claim 1 , wherein the frame structure is configured to expand within the native valve.
15 . The device of claim 1 , wherein the compressed configuration is sized and dimensioned for percutaneous insertion and the expanded configuration is sized and dimensioned for implantation in the native valve.
16 . The device of claim 1 , wherein the frame structure comprises a first and second opposite ends, the first end configured to extend above the native valve and the second end configured to extend below the native valve when the frame structure is anchored to the native valve.
