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 and/or a removable and/or replaceable shunt portion. Devices may include absorbable materials, the absorption of which directly or indirectly causes alterations of the fluid flow capacities the devices.
Claims23
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, a first side and a second side of the membrane;
- a retainer interconnecting the first and second anchors, the retainer being adapted to permit blood to flow across the membrane at a first flow rate;
- and
- a shunt removably attachable to the retainer, the shunt being receivable within the retainer so as to enable the device to conduct blood across the membrane at a second flow rate, the shunt configured to be percutaneously delivered to the retainer after the retainer is implanted into the membrane of the patient's heart, wherein the shunt comprises a frame having at least one aperture associated with a flap releasably secured in place with a bio-resorbable material so as to partially close the aperture.
