Abstract
A catheter assembly for delivering a medical implant may include an inner shaft around which a compartment is defined, the compartment being adapted to receive the medical implant therein. The catheter assembly may include an outer shaft coaxially surrounding at least a portion of the inner shaft and movable in longitudinal directions relative to the inner shaft. The outer shaft may define a lumen therein, the inner shaft and the outer shaft together defining a space therebetween, the space providing liquid communication between a proximal end of the catheter assembly and the compartment. The catheter assembly may include a distal sheath fixedly connected to the outer shaft, the distal sheath being movable between a closed condition covering the compartment and an open condition uncovering the compartment for deployment of the medical implant. A lubricant containing albumin may be disposed within at least a portion of the space.
