Abstract

According to the present invention, an alignment device for marking and aligning selected positions on a heart'"'"'s surface is provided. The device includes a handle assembly having upper and lower handle portions which are detachable from one another. Each handle portion is connected to a tissue engaging member which may be secured to the surface of the heart via a vacuum. The tissue engaging members are articulatable with respect to the handle portions, such that movement of the handle portions after the tissue engaging members are secured to the heart'"'"'s surface will not dislodge or displace the tissue engaging members. The tissue engaging members may be permanently or detachably connected to the handle portions. The tissue engaging members may also be used to locate and mark desired positions on the heart. In use, after the tissue engaging members are secured to the surface of the heart, the handle portions are manipulated to connect to one another.

Claims

1. A method of implanting an elongate member transverse a heart, comprising:

selecting first and second locations on the heart;

placing a first heart engaging member at the first location;

placing a second heart engaging member at the second location while the second heart engaging member is not connected to the first heart engaging member;

passing a path-creating member through the first and second heart engaging members and through the heart; and

placing an elongate member through the heart along a path created by the path creating member.

2. The method of claim 1, further including securing the first heart engaging member to the first location via suction.

3. The method of claim 2, further including securing the second heart engaging member to the second location via suction.

4. The method of claim 1, further including connecting a first arm connected to the first heart engaging member with a second arm connected to the second heart engaging member.

5. The method of claim 4, wherein the connecting includes connecting a first handle portion supporting the first arm to a second handle portion supporting the second arm.

6. The method of claim 1, further including articulating a first arm relative to the first heart engaging member.

7. The method of claim 6, further including articulating a second arm relative to the second heart engaging member.

8. The method of claim 7, further including connecting the first and second arms via a handle assembly.
