Abstract
Abstract Devices and methods for treating heart disease by normalizing elevated blood pressure in the left and right atria of a heart of a mammal are disclosed. Devices may include an adjustable hydraulic diameter shunt portion which can be manually adjusted in vivo. Methods are provided for adjusting the flow rate of the devices in vivo.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
1 . 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.
Claim 2
Dependent Claim
142 words
1 . 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.
Claim 3
Dependent Claim
25 words
2 . The device of claim 1 , wherein the stent further comprises a cylindrical liner disposed within and attached to the inner cylindrical body.
Claim 4
Dependent Claim
28 words
3 . The device of claim 1 , wherein the outer cylindrical body has hooks and the hooks connect the outer cylindrical body to the inner cylindrical body.
Claim 5
Dependent Claim
16 words
4 . The device of claim 1 , wherein the plastically deformable material is stainless steel.
Claim 6
Dependent Claim
14 words
5 . The device of claim 1 , wherein the superelastic material is nitinol.
Claim 7
Dependent Claim
20 words
6 . The device of claim 1 wherein each of the first and second anchors comprises a plurality of segments.
Claim 8
Dependent Claim
20 words
7 . The device of claim 1 wherein the first anchor, the second anchor, and the stent are integrally connected.
