Abstract: A medical device includes a base having a needle channel and a first surface configured to be secured to a patient's skin. An insertable member is configured to be secured to the base with a length portion of the insertable member extending out of the needle channel at the first surface, for insertion through the patient's skin at an insertion site. A septum extends across the needle channel. The septum has a body through which an insertion needle may be selectively extended to facilitate the subcutaneous insertion of the length portion of the insertable member. The septum provides a liquid seal across the needle channel. The needle channel and the septum provide a sealed volume in which a limited amount of blood or other fluid from the insertion site may be held.

Abstract: A sensor introducer for a physiological characteristic sensor assembly includes a sensor introducer body that includes an outer housing that defines an opening to receive the physiological characteristic sensor assembly and an inner housing surrounded by the outer housing. The sensor introducer includes a cradle movable relative to the inner housing from a first position to a second position to deploy the physiological characteristic sensor assembly. The cradle has a cradle flange to receive the physiological characteristic sensor assembly and a cradle body that receives a needle assembly. The cradle body includes at least one locking projection that engages the inner housing to inhibit the movement of the cradle relative to the inner housing in the first position and the at least one locking projection is movable relative to the inner housing to enable the cradle to move from the first position to the second position.
