Abstract
An ambulatory medical device including a reservoir, a fluid transfer device operably connected to the reservoir, and a pressure regulator that has a valve seat and a valve element movable between a closed position where the valve element engages the valve seat and prevents fluid flow and an open position where the valve element is in spaced relation to the valve seat and does not prevent fluid flow. One of the valve seat and the valve element includes a main portion and a seal portion that is less tacky than the main portion and is engaged by the other of the valve seat and the valve element when the valve element is in the closed position.
