Abstract
A system for delivery of a medical device to a target site within the body of a patient includes an introducer sheath, and a delivery assembly receivable within a passageway of the sheath. The delivery assembly comprises an inner tubular and an outer tubular member. At least a distal portion of the inner tubular member has a diameter such that the medical device is receivable thereover. The outer tubular member is generally coaxial with the inner tubular member, and has a length such that the outer tubular member distal end terminates proximal to the inner tubular member distal portion. The outer tubular member has a first outer diameter at the proximal end and extends for a length of the outer tubular member to a first diameter boundary point. The outer tubular member has a gradual inward taper in the distal direction from the boundary point to a second outer diameter, and has an abrupt outward taper in the distal direction from the second diameter to the first diameter.
