1. A minimally invasive method of accessing an interior portion of a patient'"'"'s heart, comprising:
- a. providing an elongated treatment instrument having an operative distal portion;
b. providing an accessing port having an inner lumen and a valve within the inner lumen, said valve reducing proximal passage of blood through the inner lumen and allowing distal passage of the treatment instrument through the inner lumen;
c. forming a small passageway through a ventricular wall in an apical region of the patient'"'"'s heart;
d. seating the accessing port within the passageway formed in the apical region of the patient'"'"'s ventricular wall;
e. advancing the treatment instrument having an operative distal portion through the inner lumen of the seated accessing port into an interior of the patient'"'"'s heart until the operative distal portion of the treatment instrument is located in a desired treatment area within the patient'"'"'s heart;
f. treating the patient'"'"'s heart with the operative distal portion of the treatment instrument; and
