Abstract
Vascular access systems and devices for facilitating repeated access to a blood vessel for the external treatment of blood, such as dialysis, and in intra-venous administration of medicines, such as heparin, for extended periods of time. The vascular access systems comprise an anastomosis graft vessel, an occlusal balloon, and a port device for accessing the occlusal balloon. Occlusal balloons can be nonpermeable or permeable to drive an osmotic gradient and to deliver agents, such as heparin, into the blood stream. In addition, occlusal balloons can adopt a distended and a collapsed configuration, the latter allowing for blood flow through the anastomosis graft vessel.
Claims37
A vascular access system for facilitating repeated access to a blood vessel, the apparatus comprising:
- (a) a graft vessel means for providing a fluid conduit, the graft vessel means having an anastomosis end and an opposite port end, the graft vessel means being adapted for anastomosis at its anastomosis end with a blood vessel;
- (b) means for selectively occluding an opening in a blood vessel at the anastomosis end of the graft vessel means, said occluding means being positioned at the anastomosis end of the graft vessel means, said occluding means being adapted for distension and contraction at the anastomosis end of the graft vessel means to enable the occluding means to block fluid communication between the graft vessel means and a blood vessel when expanded in a distended position and to permit fluid communication between the graft vessel means and the blood vessel when contracted to a contracted position;
- and
- (c) means for selectively providing access to the occluding means, the means for selectively providing access being attached in a leak proof manner to the occluding means to provide fluid communication, the means for selectively providing access being configured to remain within a patient's body after anastomosis of the graft vessel means to the blood vessel while being accessible from outside of the patient's body to deliver and withdraw fluids and cause selective distention and contraction of the occluding means.

A vascular access system for facilitating repeated access to a blood vessel, the apparatus comprising:
- (a) a graft vessel with an anastomosis end and an opposite port end, the graft vessel being adapted for anastomosis at its anastomosis end with a blood vessel;
- (b) an occlusal balloon having an interior capable of receiving a fluid, said occlusal balloon being positioned and adapted for distension and contraction to enable the occlusal balloon to block fluid communication between the graft vessel and the blood vessel at the anastomosis en of the graft vessel when the occlusal balloon is expanded in a distended position and to permit fluid communication between the graft vessel and the blood vessel when contract to a contracted position;
- and
- (c) a port device attached in a leak proof manner to the occlusal balloon to provide fluid communication, the port device being configured to remain within a patient's body after anastomosis of the graft vessel to the blood vessel while being accessible from outside of the patient's body to deliver and withdraw fluids and cause selective distension and contraction of the occlusal balloon.

- (a) a graft vessel means for providing a fluid conduit, the graft vessel means having an anastomosis end d an opposite port end, the graft vessel being adapted for anastomosis at its anastomosis end with a blood vessel;
- (b) means for selectively occluding an opening at the anastomosis end, said occluding means extending integrally from the graft vessel, said occluding means being positioned and adapted for distension and contraction in a manner that enables the occluding means to block fluid communication between the graft vessel means and a blood vessel at the anastomosis end of the graft vessel when the occluding means is expanded in a distended position and that permits fluid communication between the graft vessel and the blood vessel hen contracted to a contracted position;
- and
- (c) means for selectively providing access to the occluding means, the means for selectively providing access being attached in a leak proof manner to the occluding means to provide fluid communication, the means for selectively providing access being configured to remain within a patient's body after anastomosis of the graft vessel means to a blood vessel while being accessible from outside of the patient's body to deliver and withdraw fluids and cause elective distention and contraction of the occluding means.
