No. 13/632,104 entitled “Trans-Catheter Ventricular Reconstruction Structures, Methods, and Systems for Treatment of Congestive Heart Failure and Other Conditions,” filed Sep. 30, 2012, which is related to and claims the benefit of the following U.S. Provisional Patent Applications: Application No. 61/541,624 entitled “Trans-Catheter Ventricular Reconstruction Structures, Methods, and Systems for Treatment of Congestive Heart Failure and Other Conditions,” filed Sep. 30, 2011, Application No. 61/541,975 entitled “Remote Pericardial Hemostasis for Ventricular Access and Reconstruction or Other Organ Therapies,” filed Sep. 30, 2011; Application No. 61/541,980 entitled “Over-The-Wire Cardiac Implant Delivery System for Treatment of CHF and Other Conditions,” filed Sep. 30, 2011; and U.S. Provisional Patent Application No. 61/541,978 entitled “Cardiac Implant Migration Inhibiting Systems,” filed Sep. 30, 2011; the full disclosures of which are incorporated herein by reference in their entirety.
1. A method for treating a heart within a patient, the heart having a right ventricle and a left ventricle with a septum there between, the method comprising:
advancing a first catheter from a first position outside the patient, through the vasculature, and into the right ventricle so that a distal end of the first catheter is disposed in the right ventricle;
advancing a first member from the distal end of the first catheter so that the first member is positioned within the right ventricle;
advancing a needle from a second position outside the patient and penetrating tissue of an exterior wall of the left ventricle and tissue of the septum so that a distal end of the needle is disposed in the right ventricle;
advancing a second catheter from the second position outside the patient, through the penetration in the exterior wall of the left ventricle, and through the penetration in the septum so that a distal end of the second catheter is disposed in the right ventricle;
advancing a second member from the distal end of the second catheter so that the second member is positioned adjacent the first member;
coupling the first member and the second member to form a path from the first position outside the patient, through the vasculature, through the septum and exterior wall, and to the second position outside the patient;
advancing a first anchor and an elongate tension member into the right ventricle, via a delivery catheter, along the formed path so that the first anchor is positioned against the septum with the tension member extending from the first anchor, through the septum, through the left ventricle, and through the exterior wall with a distal end of the tension member disposed outside the heart;
coupling a second anchor to the tension member outside the heart;
advancing the second anchor, via an anchor engagement tool, into engagement with the exterior wall; and
applying tension between the first and second anchors via the tension member so that the first and second anchors urge the septum and the exterior wall toward one another.
2. The method of claim 1, wherein the first member is advanced from the distal end of the first catheter so that the first member is positioned adjacent a pulmonary artery of the heart.
3. The method of claim 2, wherein the first member is a snare device that is positioned adjacent the pulmonary artery, the snare device being configured to snare the second member adjacent or within the pulmonary artery.
4. The method of claim 3, wherein the second member is advanced from the distal end of the second catheter in a manner so that the second member flows with blood into the pulmonary artery.
5. The method of claim 4, wherein the second member includes a component that enables the second member to flow with blood into the pulmonary artery.
6. The method of claim 4, wherein the second member is a guidewire or a third catheter.
7. The method of claim 1, wherein the second member is a snare device that is positioned adjacent the pulmonary artery, the snare device being configured to snare the first member adjacent or within the pulmonary artery.
8. The method of claim 7, wherein the first member is a guidewire or a third catheter.
9. The method of claim 1, wherein coupling the first member and the second member together comprises pulling the second member through the first catheter so that a distal end of the second member is disposed at the first position outside the patient.
10. The method of claim 1, further comprising inhibiting migration of the first and second anchors by applying a desired anchor force between the tension member and the second anchor while the second anchor is slidably moveable along the tension member, the second anchor being reconfigurable to inhibit sliding movement of the second anchor along the tension member after the desired anchor force is applied.
11. The method of claim 1, wherein the first anchor and the tension member are advanced into the right ventricle while the heart is beating and with the first anchor axially aligned with the tension member in a low profile configuration, and wherein the first anchor is pivotable to a deployed configuration in which the first anchor is not axially aligned with the tension member.
12. The method of claim 1, wherein the delivery catheter is the first catheter.
13. A method for treating a heart within a patient comprising:
advancing a first elongate shaft from a first position outside the patient and into a right ventricle of the heart;
advancing a first member from the first elongate shaft to a position within the right ventricle;
advancing a second elongate shaft from a second position outside the patient and through a left ventricle wall and a septal wall so that a distal end of the second elongate shaft is disposed in the right ventricle;
advancing a second member from the second elongate shaft to the position adjacent the first member;
coupling the first member and the second member to form a path from the first position outside the patient, through the heart, and to the second position outside the patient;
advancing, via a delivery catheter, a first anchor and an elongate tension member into the right ventricle along the formed path so that the first anchor is positioned against the septal wall with the tension member extending from the first anchor and through the sepal wall and the left ventricle wall;
advancing, via an anchor engagement tool, the second anchor into engagement with the left ventricle wall; and
applying tension between the first anchor and the second anchor via the tension member to urge the septal wall and left ventricle wall toward one another.
14. The method of claim 13, wherein the second elongate shaft is a needle that is configured to penetrate through the left ventricle wall and the septal wall.
15. The method of claim 13, wherein the second elongate shaft is a catheter that includes a tissue penetrating distal end that is configured to penetrate through the left ventricle wall and the septal wall.
16. The method of claim 13, wherein the first member is advanced from the first elongate shaft to a position adjacent a pulmonary artery of the heart.
17. The method of claim 16, wherein the first member is a snare device that is configured to snare the second member adjacent or within the pulmonary artery.
18. The method of claim 17, wherein the second member is a catheter.
19. The method of claim 17, wherein the second member is advanced from the distal end of the second elongate shaft in a manner so that the second member flows with blood into the pulmonary artery.
20. The method of claim 13, wherein the delivery catheter is the first elongate shaft.
