Abstract
A vascular access system is provided for providing blood flow between two locations in a vascular system of a patient. The vascular access system includes a fluid conduit configured to be fluidly coupled to a first location and a second location in the vascular system of the patient. The fluid conduit includes a peripheral portion comprising a first inner diameter, and a central portion comprising a second inner diameter that is smaller than the first inner diameter.
Claims18
A vascular access system for providing blood flow between two locations in a vascular system of a patient, the vascular access system comprising:
- a fluid conduit comprising:
- a peripheral portion comprising a first inner diameter;
- and
- a central portion comprising a second inner diameter that is smaller than the first inner diameter.
A vascular access system for providing blood flow between two locations in a vascular system of a patient, the vascular access system comprising:
- a first fluid conduit configured to be fluidly coupled to a first location in the vascular system of the patient, the first fluid conduit comprising a wall structure comprising a self-sealing element;
- a second fluid conduit fluidly coupled to the first fluid conduit, the second fluid conduit comprising:
- a lumen;
- a central end configured to be fluidly coupled to a second location in the vascular system of the patient;
- and
- a tapering portion tapering the lumen from a first diameter to a second diameter;
- and
- a connector comprising:
- a peripheral portion configured to engage a central end of the first fluid conduit;
- a central portion configured to engage a peripheral end of the second fluid conduit;
- and
- a lumen extending through the connector, the lumen of the connector configured to provide a fluid pathway from the first fluid conduit to the second fluid conduit.
The vascular access system of 12, wherein the tapering portion is less than 20 percent of the length of the second fluid conduit.
