Abstract
Embodiments disclosed herein generally relate to an access sheath and access systems. In some embodiments, the access sheath may be non-adjustable access sheath or an adjustable access sheath. For example, a length of the adjustable access sheath may be modified or customized (e.g., before insertion thereof in a patient) to a suitable length for a particular patient. In some embodiments, the access sheath and/or dilator may have a substantially fixed or predetermined length.
