Abstract
In a particular embodiment, the present disclosure provides a delivery apparatus for delivering a medical device. The delivery apparatus includes an elongated component with an engagement portion and a disengagement portion. Rotating the elongated component in a first rotational direction moves the travelling component along the engagement portion in a first axial direction. When the travelling component is located within the disengagement portion, continued rotation of the elongated component in the first rotational direction does not cause further movement of the travelling component in the first axial direction. A biasing member is located proximate the disengagement portion and urges the travelling component to reengage the engagement portion. The delivery apparatus can reduce or prevent damage to the delivery apparatus, or a patient with whom the delivery apparatus is used, by reducing or eliminating torque transfer from the travelling component to an end of the elongated component.
