Abstract
An introducer for providing intravascular access to a patient is disclosed, and includes a dilator and sheath that are configured to prevent peelback, or 'fishmouthing,' of the sheath during introducer advancement. In one embodiment, the introducer comprises a dilator including a distal tapered region, and a sheath including an inner bore that receives the dilator such that a portion of the tapered region of the dilator extends from the sheath distal end. A distal outer surface of the sheath includes a first curved portion defined by a first radius and extending proximally from the distal end of the sheath to a first end point, and a second curved portion defined by a second radius and extending proximally from the first end point to a second end point. Additionally, an interference fit is established between the dilator tapered region and the sheath distal end to further prevent sheath end deformation.
