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.
Claims45
An access system, comprising:
- an access handle including:
- a wall including an interior surface defining a funnel having an opening at a proximal end of the access handle;
- and
- a lip positioned near the opening of the funnel and extending outward from an exterior surface of the wall;
- a tubular access sheath secured to the access handle;
- a retainer including:
- a base;
- a plurality of clips operably connected to the base, the plurality of clips being sized and configured to clamp about the lip of the access handle;
- and
- a tapered section that has a generally conical shape and extends outward in a distal direction from the base;
- and
- a dilator sized and shaped to be positioned inside the access sheath, the dilator being secured to the retainer.

An access system, comprising:
- an access handle including:
- a wall including a first interior surface defining a funnel having an opening at a proximal end of the access handle and a second interior surface extending proximally from the first interior surface;
- and
- a lip positioned near the opening of the funnel and extending outward from an exterior surface of the wall;
- a tubular access sheath secured to the access handle;
- a retainer including:
- a base;
- a plurality of clips operably connected to the base, the plurality of clips being sized and configured to clamp about the lip of the access handle;
- and
- an outer surface extending distally relative to the base, the outer surface having a complementary size and shape to the second interior surface of the wall of the access handle;
- and
- a dilator sized and shaped to be positioned inside the access sheath, the dilator being secured to the retainer.
