    摘要: An introducer assembly (60) is provided with a dilator tip (40) which has at least one portion (46) which is asymmetric in transverse cross-section, preferably being flattened or oval. A dilator tip (40) which is asymmetric over at least a part of its length gives the tip different flexure characteristics in different radial directions (54, 56). This provides advantages in trackability of the dilator tip (40) and thus of the introducer assembly (60) as well as providing for self-orientation of the dilator tip (40), useful in orienting medical devices or treatment tools.

    摘要: An introducer assembly (10) is provided with a sheath (12) and carrier element (20). The sheath (12) is oval in axial cross-section and has an oval internal wall (24). The carrier element (20) has an outer wall (22) which is oval and which has a shape corresponding to the shape of the internal wall (24) of the sheath (12). The non-round shapes of the sheath (12) carrier element (20) extend the whole length of the introducer (10).

    摘要: An introducer assembly (100) including at its distal end a dilator tip (20) and an inner catheter for supporting an implantable medical device (1) for deployment, is provided with a plurality of strut elements (102, 202) extending from the dilator tip (20) to the proximal end of the medical device (1). The strut elements (102, 202) act to apply both a pulling and a pushing force against the proximal end of the medical device (1), having the effect of assisting in the correct positioning of the proximal end of the medical device in a patient's lumen, particularly where this is curved such as with the aortic arch. The strut elements (102, 202) form part of the introducer assembly and are removed from the patient following the deployment procedure. The device avoids the need for bare stents at the end of a stent graft.
