Abstract

Diagnostic and surgical procedures may be performed on a beating heart using an assembly which includes a port and a fluid transport device. The port has a housing for insertion through a wall of the heart chamber and may include one valve disposed in the housing and an inlet connected to the housing. Methods for repair and diagnosis of the heart are also described. A specific method for repairing a mitral valve uses staples which may be banded together with a strip of material.

Claims

1. A method of accessing an interior of a heart chamber of a heart, comprising:

inserting a port into a chamber wall of the heart chamber while the heart remains beating, the port having a lumen therethrough for accessing the interior of the heart chamber from exterior of the heart chamber;

inserting a stapling device through the lumen of the port; and

positioning staples from the stapling device into at least a portion of a mitral valve annulus to reduce a length of the portion of the mitral valve annulus.

2. The method of claim 1, wherein the inserting step comprises securing the port in an atrial wall to access an interior of the heart.

3. The method according to claim 1, further comprising the step of connecting the staples together with a strip of material.

4. The method according to claim 1, wherein the positioning step comprises placing staples into the posterior mitral annulus.
