Abstract
A fixation device for securing together leaflets of a heart valve is provided. The fixation device may comprise two plates that are disposed on either side of the tricuspid valve. The plates may be secured to one another by a locking clip, thereby securing the valve leaflets between the plates.

A method of performing a procedure in a heart, comprising:
- providing a delivery catheter to a heart;
- passing a distal plate through the delivery catheter and into a right ventricle of the heart;
- drawing the distal plate against a leaflet of a tricuspid valve;
- passing a proximal plate through the delivery catheter and into a right atrium of the heart;
- positioning the distal and proximal plates such that the leaflet of the tricuspid valve is compressed between the distal and proximal plates;
- aligning the distal and proximal plates;
- and
- advancing a locking clip comprising an open end and a closed end initially over the proximal plate and subsequently over the distal plate to secure the distal plate to the proximal plate.
