Method and Apparatus for Mitral Valve Annuloplasty

A method for mitral valve annuloplasty, comprising:

• inserting a catheter apparatus across an aortic valve, the catheter apparatus including a tissue penetration member having a distal fixation end, the tissue penetration member surrounded by a sheath;
• penetrating an aortomitral continuity and tissue of a fibrous trigone with the catheter apparatus from a left ventricular outflow tract beneath the aortic valve;
• advancing the catheter apparatus along annular tissue of a mitral valve annulus;
• retracting the sheath to deploy the distal fixation end and engage the annular tissue;
• calibrating a desired distance for reduction of the annular tissue;
• retracting the tissue penetration member within the catheter apparatus to compress the annular tissue the desired distance;
• and
• deploying a grommet along the tissue penetration member to secure the retracted tissue penetration member and anchor the annular tissue reduction at the aortomitral continuity.

A catheter apparatus for mitral valve annuloplasty, comprising:

• a housing;
• a retractable tissue penetration member disposed within the housing and having a distal fixation end configured to engage annular tissue of a mitral valve annulus in a deployed position;
• a retractable sheath surrounding the tissue penetration member operable to retract with respect to the tissue penetration member to provide the deployed position of the distal fixation end;
• and
• a one-way grommet disposed along the tissue penetration member for securing the tissue penetration member in a retracted position to anchor the annular tissue at a desired distance.
