Abstract

See full text

An introducer assembly (10) includes a sheath (18) having a proximal portion (26) with a greater wall thickness and a distal portion (30) with a smaller wall thickness. A transition portion (28) may be provided to give a gradual transition between the proximal and distal portions (26, 30). The outer surface (32) of the sheath (18) has a substantially smooth and preferably even form and preferably constant diameter. The sheath (18) can thus have a greater flexibility at its distal end that at its proximal end, to improve trackability and thus to facilitate deployment of an implantable medical device (16) carried by the introducer (10). The smooth outer surface (22) prevents snagging of the introducer assembly (10) during and after the deployment procedure.
