Title: EXPANDABLE CARDIAC SHUNT AND DELIVERY SYSTEM
Abstract:
Disclosed are cardiac shunts and method of delivery, and in particular, to a shunt to reduce elevated left atrial pressure (LAP). The methods include forming a puncture hole between the left atrium and the coronary sinus, widening the puncture hole, and placing an expandable shunt within the widened puncture hole. A first catheter having a side-extending needle may be used to form a puncture into the left atrium. A second catheter extends along a guide wire and an expandable shunt with distal and proximal flanges is expelled therefrom into the puncture. The shunt defines a blood flow passage therethrough that permits shunting of blood from the left atrium to the coronary sinus when the LAP is elevated. The shunt is desirable formed of a super-elastic material and manipulated with control rods. The shunt defines a tilted flow tube that facilitates collapse into the catheter.
