Methods and apparatus using an anchored balloon for treating pulmonary arterial hypertension
First Claim
1. A system for treating pulmonary hypertension, said system comprising:
- an implantable port configured for subcutaneous implantation and having an internal chamber;
a guide conduit attached at one end to the implantable port;
an inflatable balloon attached at another end of the guide conduit to receive an inflation medium therefrom;
an actuating wire having a distal end with at least one tissue-penetrating element for anchoring within the heart chamber; and
a catheter having a T-branch that is configured to lie within the heart chamber, wherein (1) one branch of the T extends into the pulmonary artery and has a passage that slidably receives the guide conduit to deploy the guide conduit and the inflatable balloon from the catheter within the pulmonary artery and (2) the other branch of the T has a passage that slidably receives the actuating wire to deploy the at least one tissue-penetrating element from the catheter to anchor the catheter within the heart chamber, wherein the tissue-penetrating element is movable independently of the balloon.

Abstract
A device (1) includes at least an inflatable balloon (2), an implantable port (2A), and a conduit (3) intended for connecting the balloon (2) and the implantable port in a sealed manner. The balloon (2), the port (2A), and the conduit (3) are filled with a gas, and the pressure is such that the balloon (1) is normally inflated but is capable of being compressed during systole. A catheter (5) slidingly carries the balloon (2) in a deflated condition. At least one anchoring member (6) is connected to an actuating wire (7) which is slidable in the catheter independently of the balloon (2). The conduit (3) and said actuating wire (7) are connected to the catheter (5) to either prevent or allow sliding of this conduit and of this actuating wire relative to the catheter (5).
