Abstract

A method of placing an electrical lead of an implantable cardiac device inside a heart of a patient. The method includes securing a tool to an atrial appendage of the heart to hold onto the atrial appendage, piercing the atrial appendage, and creating an aperture in the atrial appendage while holding the atrial appendage with the tool. The method also includes moving a distal end of the electrical lead into the heart through the aperture in the atrial appendage and into a ventricle of the heart. Furthermore, the method includes coupling the distal end of the electrical lead to cardiac tissue in the ventricle and delivering an electrical signal to the cardiac tissue in the ventricle of the heart to maintain a predetermined heartbeat of the heart.

Claims

1. A system for delivering an electrical lead to a ventricle of a heart of a patient, the system comprising:

a securing means for securing and holding onto an atrial appendage of the heart;

a piercing means for piercing and forming an aperture in the atrial appendage while the securing means holds onto the atrial appendage;

an electrical lead having a distal end, the distal end insertable through the aperture in the atrial appendage and into the left ventricle of the heart, the electrical lead connectable to an implantable cardiac device, the electrical lead delivering an electrical signal to the cardiac tissue to maintain a predetermined heartbeat; and

an abutment member that is implantable in the heart, the abutment member surrounding the electrical lead and positionable between the heart and the electrical lead to inhibit direct contact between the heart and the electrical lead.

2. The system of claim 1, wherein the securing means includes an adhesive.

3. The system of claim 1, wherein the securing means includes a suction device.

4. The system of claim 1, wherein the securing means includes a passage for passing the distal end of the electrical lead through the securing means.

5. The system of claim 1, wherein the securing means includes a passage for passage of the piercing member through the securing member.

6. The system of claim 1, wherein the abutment member is a sleeve having a lumen that receives the electrical lead.

7. The system of claim 6, further comprising a compression member that compresses the abutment member against the electrical lead to hold the electrical lead in place relative to the abutment member.

8. A system for delivering an electrical lead to a ventricle of a heart of a patient, the system comprising:
