Abstract: In one example, a medical device includes a housing having a channel configured to receive an electrical lead. The medical device can further have a rotatable member having a longitudinal axis about which the rotatable member is configured to rotate. The rotatable member can have an outer surface having a first radius from the longitudinal axis. The rotatable member can also have a cam lobe extending farther from the longitudinal axis than the first radius of the outer surface. The cam lobe can have a substantially planar surface parallel to the longitudinal axis. The substantially planar surface of the cam lobe can be configured to retain the electrical lead within the channel. The medical device can further have a slider having a central portion substantially parallel with the cam lobe. The slider can further have a slider protrusion on the central portion of the slider.

Abstract: This disclosure is directed to systems and methods that facilitate the removal of tissue for implantation of an implantable medical device into bone or other substantially rigid tissue of a patient. An example system may include a shroud for a bone drill, the shroud including a housing extending along an axis and defining an inner surface around the axis. The inner surface may terminate at an edge of the housing and defining a cavity. The cavity may be configured to receive a drill bit having a shank and a primary cutting surface extending substantially parallel to the axis. The shroud also may include a collar coupled to the housing and configured to engage a distal portion of the bone drill.
