Abstract

A method and implantation tools for placing a transventricular splint including a tension member. The method includes gaining access to the patient's hearts and identifying entry or exit points for the tension member, marking those locations and delivering the tension member. Anchors for the tension member are also delivered. The length of the tensions member is measured and the walls of the heart drawn together. The pads are secured to the tension member and the tension member is trimmed to length. The pads are secured to the heart surface.

Claims14

Dependent claims

A minimally-invasive surgical procedure comprising:

forming an incision through a patient's chest wall to create a chest access point;
advancing a catheter through the chest access point toward a target location on an exterior surface of a patient's heart, wherein the target location is proximate an apex of the patient's heart;
penetrating heart wall tissue at the target location on the patient's heart to create an opening in the heart wall and into a ventricle of the patient's heart, wherein the opening in the heart wall extends entirely through the heart wall from the outside of the heart and into the ventricle;
advancing the catheter through the opening in the heart wall;
deploying a device from the distal end of the catheter to implant the device in contact with heart tissue to restore heart functionality;
and
removing the catheter from the patient's heart while leaving the device implanted in the heart tissue.
