Sterile housing for non-sterile medical device component

An apparatus comprising:

• (a) an electrically powered medical device, wherein the medical device includes a connection feature;
• (b) a compartment selectively attachable and detachable with the electrically powered medical device, wherein an internal portion of the compartment is operable to receive at least one battery;
• (c) a connection feature extending through a wall of the compartment, wherein the compartment forms a seal about a perimeter of the connection feature, wherein the connection feature is formed of an electrically conductive material
• wherein the connection feature of the medical device is structured to selectively couple with the connection feature of the compartment.

A method for providing power to an electrically powered, medical device by using a battery pack and a membrane barrier, wherein the battery pack comprises at least one battery contained therein, wherein the battery pack further comprises at least one electrode, the method comprising:

• (a) maintaining a gap between the membrane barrier and the at least one electrode via a web member;
• (b) positioning the battery pack proximate to the medical device such that the web member and the membrane barrier are positioned between the battery pack and the medical device, wherein the membrane barrier isolates the battery pack from the medical device such that the medical device is substantially isolated from contamination by the battery pack;
• (c) collapsing the web member toward the membrane barrier by pressing the medical device against the exterior of the web member thereby eliminating the gap between the membrane barrier and the at least one electrode and thereby breaching the membrane barrier between the battery pack and the medical device, wherein the act of breaching the membrane barrier comprises urging the at least one electrode against the membrane barrier;
• and
• (d) establishing electrical communication between the at least one battery and the medical device through the at least one electrode after or upon breaching the membrane barrier.
