Method and system for placement of electrical lead inside heart

A method for maintaining a predetermined heartbeat of a patient, the method comprising:

• introducing a tool through a chest wall of the patient;
• securing the introduced tool to an outer surface of a left atrial appendage of the heart to hold onto the left atrial appendage;
• piercing a wall of the atrial appendage with a piercing tool that is operably coupled to the tool to create an aperture through the wall of the left atrial appendage while holding onto the left atrial appendage;
• moving a distal end of an electrical lead through the chest wall and the aperture and into a left ventricle of the heart via a passage in the tool, while holding onto the left atrial appendage;
• mounting a sleeve within the aperture, such that a lumen of the sleeve receives the electrical lead, when moved through the aperture, the sleeve preventing direct contact between the heart and the electrical lead;
• compressing the sleeve to hold the electrical lead in place relative to the heart;
• connecting the distal end of the electrical lead to cardiac tissue inside the left ventricle of the heart;
• connecting the electrical lead to an implantable cardiac device;
• delivering an electrical signal to the cardiac tissue via the electrical lead to maintain the predetermined heartbeat;
• manipulating the tool to resiliently stretch a resilient ring over an outer surface of the left atrial appendage;
• and
• manipulating the tool to release the resilient ring to resiliently recover and occlude the left atrial appendage.
