Battery with suture hole

A method of implanting a medical device in a patient comprising:

• operatively coupling a lead of the medical device to a biological tissue of the patient;
• introducing a generator of the medical device into the patient;
• and
• coupling a housing assembly of the generator to the patient via an aperture defined in the housing assembly.

A medical device implantable within a blood vessel of a patient comprising:

• a generator with a control assembly having a control case, the generator also including a battery assembly with an anode, a cathode, and a battery case that encloses the anode and the cathode, the control case and the battery case being fixedly coupled, the control case and the battery case being substantially cylindrical, elongate and being coaxial along a straight axis, the battery case including an end;
• a through-hole extending through the end of the battery case in a direction substantially perpendicular to the axis, the anode and the cathode being disposed between the through-hole and the control assembly, the through-hole substantially centered on the axis;
• and
• a suture that extends through the through-hole and couples the battery case to the patient.
