<p>A device for reducing the pulmonary pressure by forcing controllable tricuspid valve regurgitation, using a catheter assembly (10), comprising, a catheter tube (12) having a proximal end and a distal end, the distal end fitted with a navigation balloon (18) inflatable through an inflation lumen. The catheter assembly further comprises an expander (20) surrounding a section of the catheter and a manipulating sleeve (30) slidingly enveloping a portion of the tube extending rearwards from the expander and forming a gap between the tube and the sleeve, whereby the expander is adapted to radially expand and contract through manipulation of the sleeve. The tube further comprises a first pressure lumen (26), a second pressure lumen (28), and a third pressure conduit (32); wherein the first and second pressure lumens and the third pressure conduit terminate at pressure outlet couplings of the tube's proximal end.</p> |
