Abstract

An implantable device for reducing pulsatile pressure within a blood vessel is described herein, for example to treat pulmonary hypertension. The implantable device may include a fluid reservoir, a compliant member (e.g., a balloon), and a conduit coupled to the fluid reservoir and the compliant member. Advanced designs for anchoring the compliant member in the blood vessel are described. In addition, enhanced reservoir, conduit, and balloon designs, as well as methods for implanting/using the same, are provided.
