Claims7
An expandable device adapted for percutaneous delivery into a membrane of a patient's heart, the device comprising:
- first and second anchors adapted to contact, respectively, first and second surfaces of the membrane;
- and
- a stent having a longitudinal axis and being connected to the first and second anchors, the stent comprising an outer cylindrical body comprising a superelastic material and an inner cylindrical body comprising a first diameter and disposed within and connected to the outer cylindrical body and comprising a plastically deformable material, the stent being adapted to permit blood to flow across the membrane at a first rate;
- wherein the inner cylindrical body is stent-like and radially expandable to a second diameter greater than the first diameter so as to permit blood to flow across the membrane at a second rate that is different from the first rate.
