Deflectable sheath for left atrial appendage device, system, and method thereof

A method for axially aligning a distal end of a medical device delivery system with an ostium of a left atrial appendage of a heart, the method comprising:

• positioning a distal end of a sheath adjacent the left atrial appendage of the heart, the sheath having a sheath handle with a pivot location member, the pivot location member moveable linearly distal and linearly proximal relative to the sheath handle, the sheath extending with a wall between a distal end and a proximal end with a central lumen and central axis defined in the sheath along a longitudinal length of the sheath such that an implant and delivery catheter are advanceable through the central lumen of the sheath, the sheath defining a concentric lumen therein so as to extend along the wall, the sheath being deflectable with a first deflectable portion relative to a first pivot location along a distal portion of the sheath and the sheath being deflectable with a second deflectable portion relative to a second pivot location along the distal portion of the sheath;
• and
• adjusting at least one of the first pivot location and the second pivot location of the first and second deflectable portions, respectively, along the longitudinal length of the distal portion of the sheath such that the at least one of the first and second pivot locations is moveable distally with linear movement of the pivot location member to a distal position and the at least one of the first and second pivot locations is moveable proximally with linear movement of the pivot location member to a proximal position.
