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 in a first configuration into a coronary sinus;
manipulating the prosthesis to a second configuration different from the first configuration to exert a compressive force on the mitral valve annulus;
monitoring hemodynamic function while the prosthesis is in the second configuration;
assessing mitral valve regurgitation in response to the monitoring step; and
adjusting the prosthesis to a third configuration different from the second configuration in response to the assessing step.

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.

19. A method of remodeling a mitral valve annulus to reduce mitral valve regurgitation, comprising the steps of:
-
advancing an adjustable prosthesis in a first configuration into a coronary sinus; manipulating the prosthesis from the first configuration toward a second configuration for exerting a compressive force against the mitral valve annulus to reduce mitral valve regurgitation; monitoring the degree of regurgitation while manipulating the prosthesis from the first configuration toward the second configuration; assessing the degree of regurgitation in response to the monitoring step; and fixing the prosthesis in the second configuration in response to the assessing step. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
