Abstract

A diagnostic device for determining the amount of change required in a coronary sinus to reduce valve regurgitation. The device includes a distal tube having a distal anchor at a distal end portion of the distal tube, a proximal tube having a proximal anchor at a distal end portion of the proximal tube, and an adjustor to move the distal tube relative to the proximal tube. The proximal tube and the distal tube together form a telescoping elongate body adapted to fit within the coronary sinus, and the device includes a scale to measure the movement of the distal anchor relative to the proximal anchor.

Claims

1. A diagnostic device for determining an amount of adjustment required in a coronary sinus to reduce heart valve regurgitation comprising:

a first elongate body having a distal anchor at a distal end portion of the first elongate body,

a second elongate body having a proximal anchor at a distal end portion of the second elongate body, and

an adjustor to move one of the first and second elongate body relative to the other of the first and second elongate bodies,

wherein the first and second elongate bodies together form a telescoping elongate body adapted to fit within the coronary sinus, and

further comprising a scale to permit measurement of the movement of the distal anchor relative to the proximal anchor, wherein the scale is on the adjustor.

2. The diagnostic device of claim 1, wherein the distal anchor and the proximal anchor are transformable between a compressed state and an expanded state.

3. The diagnostic device of claim 1, wherein movement of the adjustor by a certain distance causes movement of the first elongate body by the same distance.

4. The diagnostic device of claim 1, wherein the distal anchor and the proximal anchor comprise balloons.

5. The diagnostic device of claim 4, wherein the distal anchor and the proximal anchor are transformed from their compressed state to their expanded state by a fluid.

6. The diagnostic device of claim 1, wherein the distal anchor comprises a basket.

7. The diagnostic device of claim 1, wherein each of the first and second elongated bodies contain an inflation lumen and a guidewire lumen.

8. The diagnostic device of claim 1, wherein the adjustor comprises a handle.
