Abstract

Claims (46)

1. A transcatheter device comprising:

a connecting tube having a proximal segment having a proximal end, a distal segment having a distal end, and a middle segment between the proximal and distal segments wherein the connecting tube has a lumen for insertion of a guidewire; and

a blocking part mounted on the middle segment of the connecting tube,

wherein the proximal end of the proximal segment comprises a fixing member for anchoring in an inferior vena cava;

wherein the distal end of the distal segment comprises a fixing member for anchoring in a pulmonary artery; and

wherein the distal segment of the connecting tube has only a single pre-determined natural bend.

2. The transcatheter device of claim 1 , wherein the blocking part is an inflatable balloon.

3. A method of treating tricuspid valve regurgitation in a patient's heart, comprising:

having a transcatheter device comprising below;

(i) a connecting tube having a proximal segment having a proximal end, a distal segment having a distal end, and a middle segment between the proximal and distal segments; and

(ii) a blocking part mounted on the middle segment of the connecting tube,

(iii) wherein the proximal end of the proximal segment comprises a fixing member for anchoring in an inferior vena cava;

(iv) wherein the distal end of the distal segment comprises a fixing member for anchoring in a pulmonary artery;

inserting the transcatheter device into an inferior vena cava;

advancing the transcatheter device through a right atrium of the heart;

advancing the transcatheter device across a tricuspid valve and into a right ventricle of the heart;

advancing the transcatheter device towards a pulmonary artery;

positioning the blocking part between the leaflets of the tricuspid valve;

anchoring the fixing member of the distal segment in the pulmonary artery;

anchoring the fixing member of the proximal segment in the inferior vena cava.

4. The method of claim 3 , the method further comprises:

advancing a guidewire through the inferior vena cava;

advancing the guidewire through the right atrium;

advancing the guidewire to traverse the tricuspid valve and into the right ventricle;

introducing the guidewire into the connecting tube;

advancing the transcatheter device over the guidewire.

5. The method of claim 3 , the method further comprises:

inserting the transcatheter device into a sheath tube;

removing the transcatheter device from the sheath tube.

6. A method of positioning a transcatheter device having a blocking part, the method comprises:

inserting the transcatheter device into an inferior vena cava;

advancing the transcatheter device through a right atrium of a patient's heart;

advancing the transcatheter device across a tricuspid valve and into a right ventricle of the heart;

advancing the transcatheter device towards a pulmonary artery;

positioning the blocking part between the leaflets of the tricuspid valve;

anchoring a distal end of the transcatheter device in the pulmonary artery;

anchoring a proximal end of the transcatheter device in the inferior vena cava.

7. The method of claim 6 , the method further comprises:

advancing a guidewire through the inferior vena cava;

advancing the guidewire through the right atrium;

advancing the guidewire to traverse the tricuspid valve and into the right ventricle;

introducing the guidewire into the transcatheter device;

advancing the transcatheter device over the guidewire.

8. The method of claim 6 , the method further comprises:

inserting the transcatheter device into a sheath tube;

removing the transcatheter device from the sheath tube.
