Prosthetic valve with separably-deployable valve body and tissue anchors

A method of implanting a prosthetic valve within a native heart valve, the method comprising:

• delivering the prosthetic valve into a heart chamber while the prosthetic valve is constrained in a radially-contracted delivery configuration, wherein the prosthetic valve comprises:
• an annular valve body,
• a plurality of ventricular tissue anchors configured to extend from the annular valve body, and
• a plurality of atrial tissue anchors configured to extend from the annular valve body;
• unconstraining the ventricular tissue anchors and the atrial tissue anchors within the heart while maintaining the annular valve body in the radially-contracted delivery configuration;
• and
• while the unconstrained ventricular tissue anchors are positioned downstream of the native heart valve and while the unconstrained atrial tissue anchors are positioned upstream of the native heart valve, unconstraining the annular valve body such that the annular valve body radially expands from the radially-contracted delivery configuration into a deployed configuration,
• wherein the radial expansion of the annular valve body decreases a longitudinal distance between the unconstrained ventricular tissue anchors and the unconstrained atrial tissue anchors to secure the prosthetic valve within the native heart valve.

• delivering the prosthetic valve into a heart chamber while the prosthetic valve is constrained in a radially-contracted delivery configuration, wherein the prosthetic valve comprises:
• an annular valve body,
• a plurality of ventricular tissue anchors configured to extend from the annular valve body, wherein at least one ventricular tissue anchor has a single point of connection to the annular valve body, and
• a plurality of atrial tissue anchors configured to extend from the annular valve body, wherein at least one atrial tissue anchor has a single point of connection to the annular valve body;
• unconstraining the ventricular tissue anchors and the atrial tissue anchors within the heart while maintaining the annular valve body in the radially-contracted delivery configuration, wherein unconstraining the ventricular tissue anchors causes terminal ends of the ventricular tissue anchors to deflect radially outward relative to the annular valve body;
• and
• while the unconstrained ventricular tissue anchors are positioned downstream of the native heart valve and while the unconstrained atrial tissue anchors are positioned upstream of the native heart valve, unconstraining the annular valve body from the radially-contracted delivery configuration.
