Catheter system and methods of using same

A delivery catheter comprising:

• a main body having a proximal end portion and a distal end portion;
• a delivery catheter sheath projecting distally from the distal end portion of the main body;
• a handle member supported by the main body of the delivery catheter;
• and
• an adjustment member supported by the main body, the adjustment member being configured such that rotation of the adjustment member causes the adjustment member to move axially along the main body;
• wherein the handle member is axially moveable along the main body of the delivery catheter by either axially sliding the handle member relative to the main body or rotating the adjustment member relative to the main body.
