John R Liddicoat, Gregory H Lambrecht, Richard B Streeter, Steven B Woolfson: Automated annular plication for mitral valve repair. Viacor, Pandiscio & Pandiscio, July 5, 2005: US06913608 (410 worldwide citation)

A novel system for performing a heart valve annuloplasty. The system involves the use of a plication band. In one embodiment, the annulus of the valve is reduced by constriction of the plication band itself. More particularly, each plication band enters the tissue at two or more points which are spa ...
