Abstract: A system and method are provided for vascular access, enabling repetitive vascular access while preventing damage to the blood vessel wall, reducing hematomas, improving flow in a vessel, preventing back-wall perforation, and enabling improved fistula maturation and care. The system includes an implanted conduit that is incorporated into surrounding fibrous tissue that can guide a needle and/or catheter from a puncture site on the skin to a vessel wall, which may be used to provide repetitive vascular access for persons requiring hemodialysis or chemotherapy.

Abstract: A vascular access device is disclosed including a needle insertion guide having a proximal end and a distal end a the guide including a needle insertion guide having a proximal end and a distal end and a vessel interface configured for attaching the distal end of the guide to a target on an unbroken outer wall of a blood vessel of a living subject and a skin interface configured for attaching the proximal end of the guide to a skin of the living subject. Optionally the vessel interface is connected to the guide by a flexible joint configured. Optionally two vascular access devices are connected by an electrically conductive connection. Optionally the vascular access device includes a sensor to determine when a needle enters the blood vessel. Optionally the vascular access device serves as a marker for a sensor determining a status of the blood vessel.
