Abstract: A delivery device includes a handle, a sheath distally extending from the handle, a capsule distally extending from the sheath, and a pull wire having a proximal end attached to the handle and a distal end attached to the capsule. The sheath defines a central lumen there-through and has a longitudinally-extending lumen formed within a wall of the sheath. The capsule has a tubular body with an intermediate region having a plurality of ribs and a plurality of slots defined therein. The capsule includes an indented segment defined on the tubular body, the indented segment being disposed radially inward relative to the tubular body. The pull wire is tensioned to bend the capsule. The pull wire is slidably disposed within the longitudinally-extending lumen of the sheath and along an inner surface of the tubular body of the capsule with a portion of the pull wire crossing over an outer surface of the indented segment.

Abstract: A system for delivering an implantable medical device to an implant location includes a control handle portion, a catheter portion coupled to the control handle portion, and a distal portion configured to receive the implantable medical device. The catheter portion includes outer shaft including an inner braided layer extending axially along the outer shaft, an outer braided layer extending axially along the outer shaft, wherein the outer braided layer has a lower density of braids relative to the inner braided layer, and an axial spine positioned between the inner braided layer and the outer braided layer extending axially along the outer shaft.
