Deployment handle for a medical device deployment system

A method of deploying a medical device comprising:

• advancing the medical device to a treatment region with a delivery system including a deployment handle, the deployment handle including a first actuation member positioned at a first longitudinal position, a second actuation member, and a cover positioned at a second longitudinal position and operably coupled to the first actuation member and disposed over the second actuation member in the second longitudinal position such that the second actuation member is inaccessible;
• and
• actuating the first actuation member such that the cover is transitioned from the second longitudinal position to a third longitudinal position, the third longitudinal position including the second actuation member being accessible, wherein actuating the first actuation member includes rotating the first actuation member about a longitudinal axis of the deployment handle.

A method of deploying a medical device comprising:

• advancing the medical device to a treatment region with a delivery system including a deployment handle, the deployment handle including a first actuation member at a first longitudinal position along the handle, a second actuation member, and a cover positioned at a second longitudinal position along the handle and operably coupled to the first actuation member, the cover being disposed over the second actuation member in the second longitudinal position rendering the second actuation member inaccessible;
• and
• transitioning the cover from the second longitudinal position to a third longitudinal position where the second actuation member is rendered accessible, wherein the first actuation member is operable to rotate relative to the cover.
