1. A method of treating tricuspid valve regurgitation in a patient's heart, comprising:
having a transcatheter device comprising (i)-(iv) below;
(i) a main shaft;
(ii) a proximal portion comprising a proximal segment of the main shaft and an intravascular anchor;
(iii) a distal tail comprising a distal portion of the main shaft;
(iv) a spacer body mounted on the main shaft and located between the proximal segment of the main shaft and the distal tail;
inserting the transcatheter device into a femoral vein;
advancing the transcatheter device through 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;
advancing the distal tail into the pulmonary artery for a distance of at least 10 cm into the pulmonary artery;
positioning the spacer body between leaflets of the tricuspid valve;
lodging the intravascular anchor within the inferior vena cava.
