Abstract

A prosthetic device for implanting in a patient'"'"'s heart includes (i) a therapeutic device capable of restoring function to a native heart valve; and (ii) at least one sensor including a body, an inductor coil disposed within the body, and a capacitor in communication with the inductor coil, the at least one sensor being coupled to the therapeutic device, and being configured to monitor proper function of the therapeutic device within the patient'"'"'s heart.

Claims

1. A collapsible prosthetic device for implanting in a patient'"'"'s heart, comprising:

a stent having a plurality of struts, a proximal end, a distal end, a lumenal surface and an ablumenal surface;

a valve assembly coupled to the stent, the valve assembly including a cuff and a plurality of leaflets, the cuff being disposed only over a portion of the stent so that the stent has an exposed portion in which neither the lumenal surface nor the ablumenal surface of the stent are covered by the cuff and a covered portion in which at least one of the lumenal surface or the ablumenal surface of the stent is covered by the cuff; and

at least one sensor coupled to the exposed portion of the stent distal of the valve assembly such that the at least one sensor is spaced from the cuff and the plurality of leaflets, the at least one sensor being configured to monitor the function of a therapeutic device within the patient'"'"'s heart, the sensor including a body, an induction coil disposed within the body and a capacitor in electrical communication with the induction coil.

2. The prosthetic device of claim 1, wherein the stent includes an aortic section at the distal end of the stent, and the at least one sensor includes a plurality of sensors circumferentially disposed about the aortic section of the stent.

3. The prosthetic device of claim 1, wherein the stent includes a plurality of commissure features for coupling to the valve assembly, and the at least one sensor includes a plurality of sensors circumferentially disposed between adjacent ones of the plurality of commissure features.

4. The prosthetic device of claim 1, wherein the at least one sensor includes a plurality of sensors disposed on at least one of the proximal end and the distal end of the stent.

5. The prosthetic device of claim 1, wherein the at least one sensor is disposed on the lumenal surface of the stent.

6. The prosthetic device of claim 1, wherein the at least one sensor is disposed on the ablumenal surface of the stent.

7. The prosthetic device of claim 1, wherein the body includes a protrusion formed from fused silica projecting inwardly toward an interior of the body, and the induction coil comprises a plurality of electrically conductive windings wrapped around the protrusion.

8. The prosthetic device of claim 7, wherein the plurality of electrically conductive windings defines a gap of between about 3 microns and about 35 microns between adjacent windings.
