Abstract
A transcatheter device for treating the tricuspid valve regurgitation. The transcatheter device comprises a main shaft, a proximal device could be used for treating tricuspid valve regurgitation in a patient's heart. All or part of the transcatheter device is supported by the main shaft. The spacer body is mounted on the shaft, which travels through the spacer body. Also disclosed are a coaptation assembly that comprises the transcatheter device, and a method of treating tricuspid valve regurgitation using the transcatheter device.
Claims20
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.
A transcatheter device comprising:
- a main shaft;
- a proximal portion comprising a proximal segment of the main shaft and an intravascular anchor;
- a distal tail comprising a distal portion of the main shaft, wherein the distal tail has a length in the range of 10-40 cm long;
- a spacer body mounted on the main shaft and located between the proximal segment of the main shaft and the distal tail.
