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 surgical cutting device for performing a minimally-invasive surgical procedure and which includes an external hub including a housing and a cutter actuator housed within the housing, wherein the cutter actuator, a catheter including a first end coupled to the external hub, a second end opposite the first end, and an internal passage, a cutting tool coupled to the second end of the catheter and including a cutting element moveable relative to the second end of the catheter by the cutter actuator, and a motion transfer assembly extending through the internal passage of the catheter from the cutter actuator to the cutting tool, wherein the motion transfer assembly is configured to transfer motion from the cutter actuator to the cutting element of the cutting tool in response to the activation of the cutter actuator.

Abstract: An implantable device comprises a plurality of electrode pairs, a sensing unit, and a pacing unit. The electrode pairs comprise a first electrode pair. The first electrode pair is configured to implant at or near a first location of a heart. The sensing unit is configured to sense electrical activity in the heart, determine that the electrical activity indicates an abnormal rhythm, determine a feature of the electrical activity, and select the first electrode pair from the electrode pairs based on the feature. The pacing unit is configured to cause, in response to the abnormal rhythm and the feature, the first electrode pair to provide a first electrical pulse at a first time.
