US 11,766,331 B2 · Device and assembly to repair a heart valve

Abstract

An assembly for reshaping a cardiac ventricle in a patient comprising an implantable device for reshaping a ventricle comprising a tether, a non-implantable tool which is detachably connectable to said implantable device and has a proximal portion and a distal portion opposite to said proximal portion; the implantable device further comprises an active anchor adapted to be detachably connected to the distal portion of the tool; the active anchor comprises an abutment portion adapted to abut against a structure of the ventricle; the active anchor of the implantable device comprises an adjustment device adapted to adjust the tensional state of the tether; the distal portion of the tool comprises an adjustment key adapted to cooperate with the adjustment device of the active anchor; the proximal portion of the tool comprises a maneuvering interface which is operatively connectable to said adjustment key for adjusting the tensional state of the tether by acting on the maneuvering interface of the proximal portion of the tool.

Dependent claims

An assembly adapted to be implanted by a tool having a proximal portion and a distal portion, the assembly adapted for reshaping a cardiac ventricle of a heart in a patient, the assembly comprising:

an active anchor including a locked configuration, a released configuration, and a biasing mechanism for biasing the active anchor in the locked configuration, the active anchor further including an abutment portion adapted to abut against a wall of the ventricle of the heart and a tether portion rotatably coupled to the abutment portion, the abutment portion and tether portion defining an interior space;
an interventricular septum anchor for coupling to a septum of the heart;
and
a tether having a working portion having a first length, extending between the active anchor and the septum anchor, and a proximal portion having a second length disposed substantially within the interior space;
wherein the active anchor is configured such that a force applied to the tether portion overcomes the biasing mechanism and transitions the active anchor into the released configuration;
and
further wherein the abutment portion and the tether portion are configured such that a relative rotation of the portions adjusts the first length of the working portion and the second length of the proximal portion.

A system assembly adapted for reshaping a cardiac ventricle of a heart in a patient, the system comprising:

an active anchor including an abutment portion adapted to abut against a wall of the ventricle of the heart and a tether portion rotatably coupled to the abutment portion, the abutment portion and tether portion defining an interior space;
an interventricular septum anchor for coupling to a septum of the heart;
a tether having a working portion having a first length, extending between the active anchor and the septum anchor, and a proximal portion having a second length disposed substantially within the interior space;
and
a tool including a shaft and an adjustment key adapted to couple with and impart a rotational force upon the tether portion;
wherein the abutment portion and the tether portion are configured such that a relative rotation of the portions adjusts the first length of the working portion and the second length of the proximal portion, such that when the system is implanted in the patient, decreasing the first length of the working portion adjusts a tension in the working portion of the tether so as to reshape the cardiac ventricle;
and
further wherein the tool includes an outer case adapted to engage the abutment portion so as to support the abutment portion during the relative rotation.
