1. A device comprising:
- a shunt portion comprising a distal end, a proximal end, and a central lumen,a distal anchoring portion connecting to the distal end of the shunt portion, anda proximal anchoring portion connecting to the proximal end of the shunt portion,wherein the device has a first configuration where the shunt portion, the distal anchoring portion, and the proximal anchoring portion approximately align along a longitudinal axis, andthe device has a second configuration where the distal anchoring portion and the proximal anchoring portion turn radially away from the longitudinal axis and the device assumes a general “
U”
shape.

Abstract
The present teachings provide a device and method of making and using thereof. Specifically, one aspect of the present teachings provides a device comprising a shunt having a distal end and a proximal end and the shunt positionable across the septum of a heart. Certain embodiments of the present teachings also include a distal anchoring portion connecting to the distal end of the shunt portion and a proximal anchoring portion connecting to the proximal end of the shunt portion. Another aspect of the present teachings provide methods of using thereof to modify the pressure difference in a heart chamber.

13. A delivery assembly comprising:
-
a delivery sheath comprising a distal portion and a lumen, a delivery catheter comprising a distal end, wherein the delivery catheter is disposed within the lumen of the distal portion of the delivery sheath, and a device disposed within the lumen of the distal portion of the delivery sheath, wherein the device comprises a shunt portion, a distal anchoring portion, and a proximal anchoring portion, wherein the shunt portion comprising a distal end, a proximal end, and a central lumen;
the distal anchoring portion is connected to the distal end of the shunt portion;
the proximal anchoring portion is connected to the proximal end of the shunt portion;
the device has a first configuration where the shunt portion, the distal anchoring portion, and the proximal anchoring portion of the device approximately align with a longitudinal axis; and
the device has a second configuration where the distal anchoring portion and the proximal anchoring portion turn radially away from the longitudinal axis and the device assumes a general “
U”
shape; andthe distal end of the delivery catheter engages the proximal anchoring portion of the device. - View Dependent Claims (14, 15, 16, 17)

18. A method of implanting a device between the left and right atria of a heart comprising:
-
providing a delivery assembly comprising a delivery system comprising a lumen and a device disposed within the lumen of the delivery system, wherein the device comprises a shunt portion, a distal anchoring portion, and to proximal anchoring portion, wherein the shunt portion comprising a distal end, a proximal end, and a central lumen;
the distal anchoring portion is connected to the distal end of the shunt portion;
the proximal anchoring portion is connected to the proximal end of the shunt portion;
the device has a first configuration where the shunt portion, the distal anchoring portion, and the proximal anchoring portion of the device approximately align with a longitudinal axis; and
the device has a second configuration where the distal anchoring portion and the proximal anchoring portion turn radially away from the longitudinal axis and the device assumes a general “
U”
shape; andadvancing the delivery assembly through an aperture in the septum between the left and right atria of a heart, exposing the distal anchoring portion of the device so that the distal anchoring portion of the device turns radially away from the longitudinal axis, retracting the delivery assembly proximally so that the distal anchoring portion of the device contacts the left atrial side of the septum, exposing the proximal anchoring portion of the device so that the distal anchoring portion of the device turn radially away from the longitudinal axis, retracting the delivery system from the body, leaving the device positioned across the aperture in its second configuration with the distal anchoring portion contacting the left atrial side of the septum, the proximal anchoring portion contacting the right atrial side of the septum, and the shunt portion positioned across the aperture. - View Dependent Claims (19)
