1. A method for deploying an implantable cardiac medical device, the method comprising:
loading an entirety of the implantable medical device into a distal-most portion of an outer tube of a delivery system assembly such that a proximal end of the medical device abuts a distal end of an inner member of the delivery system assembly, the inner member extending within a lumen formed by the outer tube;
advancing the delivery system assembly within a venous system of a patient to locate the distal-most portion of the outer tube, with the medical device loaded therein, within a right atrium of the patient;
orienting the located distal-most portion of the outer tube toward a tricuspid valve of the patient by deflecting a distal end of a shaft of the delivery system assembly independently of the outer tube and the inner member, the shaft extending within the lumen of the outer tube and around the inner member such that the distal end of the shaft is positioned proximal to the distal end of the inner member;
advancing, with respect to the deflected distal end of the shaft, the distal-most portion of the outer tube through the tricuspid valve and into a right ventricle of the patient to a target implant site, such that the distal-most portion of the outer tube abuts the implant site, the advancing carrying the distal end of the inner member and the loaded medical device along with the distal-most portion, by means of an engagement of the distal end of the inner member within the lumen of the outer tube; and
retracting the outer tube with respect to the distal end of the inner member and the shaft to expose a fixation member of the medical device for engagement of tissue at the implant site.
