Percutaneous mitral annuloplasty with hemodynamic monitoring
First Claim
Patent Images
1. A method of treating a patient, comprising the steps of:
- transluminally advancing a prosthesis into the coronary sinus;
manipulating the prosthesis to exert a compressive force on the mitral valve annulus;
locking the prosthesis to retain a compressive force on the annulus following the manipulating step; and
monitoring hemodynamic function to assess mitral valve regurgitation.

Abstract
A minimally invasive method of performing mitral annuloplasty is disclosed. An implantable device is positioned within the coronary sinus and tightened around the mitral annulus. Mitral valve regurgitation is monitored before, during, and/or after the tightening step. An on-going drug therapy may be determined, taking into account post-implantation hemodynamic function.

21. A method of remodeling a mitral valve annulus to reduce mitral valve regurgitation, comprising the steps of:
-
providing a prosthesis which is adjustable between a first configuration for transluminal deployment within the coronary sinus and a second configuration for exerting a compressive force against the mitral valve annulus from within the coronary sinus;
transluminally advancing the prosthesis to a position at least partially within the coronary sinus;
tightening the prosthesis to reduce mitral valve regurgitation;
locking the prosthesis to retain a compressive force on the annulus following the tightening step; and
monitoring the degree of regurgitation. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
