Abstract: An Example tool for implanting a pacemaker lead includes a body that includes a recess, a first electrical contact positioned within the recess, and a projection coupled to the body. In addition, the tool includes a second electrical contact positioned on the projection. The recess is configured to receive the pacemaker lead therein such that a first electrode of the pacemaker lead is to engage with the first electrical contact and a second electrode of the pacemaker lead is to engage with the second electrical contact. A rotation of the tool about a central axis of the pacemaker lead is configured to rotate the first electrical contact and the first electrode together about the central axis and to slidingly engage the second electrical contact along the second electrode.

Abstract: A spirometry system operable to measure airflow through an air passage defined by a mouthpiece including one or more contact sensors configured to generate at least one mouth contact signal indicative of user mouth contact with the proximal portion of the mouthpiece. The spirometry system can further include an airflow sensor configured to generate an airflow signal corresponding to airflow within the air passage, and processor circuitry communicatively coupled to the one or more contact sensors and to the airflow sensor. The processor circuitry can be configured to determine an indication of an amount of user mouth contact for use with a measurement of airflow by the processor circuitry.
