Abstract
Balloon covers for a delivery apparatus for a prosthetic valve are disclosed. As one embodiment, a balloon cover includes first and second shell members that are configured to matingly engage with each other, each including a first portion defining a first cavity configured to receive a distal end portion of the delivery apparatus and at least a portion of an inflatable balloon. The balloon cover includes one or more depression members, each having a free end configured to move radially inward toward a central longitudinal axis of the balloon cover, and a tubular sleeve configured to be positioned around the depression members and the first portions of the first and second shell members such that the first and second shell members are held in mating engagement with each other and the free ends of the depression members are depressed radially inward and form a negative radial depression in the balloon.
