Transventricular implant tools and devices
View Patent ↗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.
1. 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.
2. The method claim 1 , further comprising:
advancing a shaft through the opening in the heart wall; and
positioning the shaft within the opening in the heart wall;
wherein advancing the catheter through the opening in the heart wall comprises advancing the catheter through the shaft.
3. The method of claim 2 , further comprising:
applying suture to the heart tissue proximate the apex to limit bleeding around the shaft.
4. The method of claim 3 , wherein applying suture to the heart tissue proximate the apex comprises applying a purse-string suture to the heart tissue proximate the apex and around the shaft.
5. The method of claim 1 , wherein the device comprises a tension member.
6. The method of claim 5 , wherein deploying the device from the distal end of the catheter to implant the device comprises passing the tension member through a ventricular wall of the heart at position away from the apex of the patient's heart.
7. The method of claim 6 , further comprising:
placing one or more anchors on the tension member to thereby secure the tension member to the ventricular wall.
8. The method of claim 1 , wherein deploying the device from the distal end of the catheter to implant the device comprises implanting the device at a position away from the apex of the patient's heart.
9. A minimally-invasive surgical procedure comprising:
performing a partial thoracotomy to create an opening through a patient's chest wall between ribs thereof to create a chest access point;
creating an opening through a heart wall of the patient's heart proximal the apex of the heart;
positioning a shaft within the opening in the heart wall;
advancing a catheter into the patient and through the shaft and through the heart wall and into a ventricle of the patient's heart, wherein the catheter comprises a catheter distal end;
positioning the catheter distal end adjacent a deployment site within the patient's heart, wherein the deployment site is away from apex of the heart;
deploying a device from the distal end of the catheter and into contact with heart tissue at the deployment site within the patient's heart; and
removing the catheter from the patient's heart while leaving the device in contact with the heart tissue.
10. The method of claim 9 , wherein the device comprises a tension member.
11. The method of claim 10 , wherein deploying the device from the distal end of the catheter to implant the device comprises passing the tension member through a ventricular wall of the heart.
12. The method of claim 11 , further comprising:
placing one or more anchors on the tension member to thereby secure the tension member to the ventricular wall.
13. The method of claim 9 , further comprising:
applying suture to the heart tissue proximate the apex to limit bleeding around the shaft.
14. The method of claim 9 , wherein applying suture to the heart tissue proximate the apex comprises applying a purse-string suture to the heart tissue proximate the apex and around the shaft.
