Delivery device for prosthetic heart valve with capsule adjustment device

A delivery device for percutaneously delivering a stented prosthetic heart valve, the stented prosthetic heart valve being radially expandable from a radially compressed configuration to a radially expanded configuration, the delivery device comprising:

• a sheath defining a lumen, wherein the sheath is configured to compressively constrain the stented prosthetic heart valve;
• a handle including a housing, a housing extension extending from a distal end of the housing along a handle longitudinal axis, and an actuator, wherein the actuator is coupled to a proximal portion of the sheath within the housing and is configured to selectively move the sheath relative to the housing to release the stented prosthetic heart valve;
• and
• an adjustment device coupled to the handle, the adjustment device including
• an adjustment housing having an adjustment lumen, the adjustment lumen surrounding an adjustment housing longitudinal axis which is aligned with the handle longitudinal axis, wherein the sheath and a portion of the handle extension slidably extend through the adjustment lumen longitudinally along the adjustment housing longitudinal axis, and
• a fine adjustment mechanism rotatably disposed around the adjustment housing such that the fine adjustment mechanism rotates parallel to the adjustment housing longitudinal axis, wherein rotating the fine adjustment mechanism moves the handle and the sheath relative to the adjustment housing.
