Abstract
A vascular access device includes a sheath body defining an outer surface and a lumen extending between a first end of the sheath body and a second end of the sheath body. The sheath body has a length of at most 7 cm. Further, the sheath body has a vessel opening defined through the first end in communication with the lumen and an access opening defined through the second end in communication with the lumen. A plurality of perfusion windows extend between and are open to the lumen and the outer surface of the sheath body, each of the plurality of perfusion windows being located within about 3 cm of the first end of the sheath body.
Claims20
A vascular access device, comprising:
- a sheath body defining an outer surface and a lumen extending between a first end of the sheath body and a second end of the sheath body, wherein:
- the sheath body has a length of at most 7 cm;
- the sheath body has a vessel opening defined through the first end in communication with the lumen and an access opening defined through the second end in communication with the lumen;
- a plurality of perfusion windows extend between and are open to the lumen and the outer surface of the sheath body.
A vascular access system, comprising:
- an access sheath including a body extending between a first end and a second end, having a length of at most 7 cm, and defining a lumen therethrough open between the first end at a vessel opening and the second end at an access opening, an outer surface of the access sheath extending between the first end and the second end coaxially with the lumen, and a plurality of perfusion windows extending between and open to the lumen and the outer surface of the sheath body;
- and
- an introducer assemblable within the lumen of the access sheath through the access opening thereof so as to extend outwardly through the vessel opening.
A vascular access sheath, comprising:
- a sheath body defining an outer surface and an interior lumen, the sheath body defining a first end and a second end opposite the first end, the outer surface and the interior lumen extending coaxially therebetween, a plurality of perfusion windows extending between and open to the lumen and the outer surface of the sheath body, all of such perfusion windows being positioned within about 3 cm of the first end;
- wherein the lumen defines:
- an access path between an access opening through the second end and a vessel opening through the first end;
- and
- a perfusion path between the vessel opening and the perfusion windows.
