Vascular access system with connector
First Claim
1. A system for providing continuous flow of blood between two locations in a cardiovascular system of a patient, comprising:
- a blood conduit having a distal portion and a proximal portion, the distal portion configured to be inserted into a blood vessel at an insertion site and to be advanced therethrough to a location spaced apart from the insertion site; and
a connector comprising;
a tubular body comprising a proximal portion and a distal portion, wherein the distal portion of the tubular body is configured to engage the proximal portion of the blood conduit, and wherein the proximal portion of the tubular body is configured to be inserted into an end of a vascular graft;
a flange extending from the tubular body between the proximal portion of the tubular body and the distal portion of the tubular body; and
a connecting device comprising first and second members pivotably connected together at one end by a hinge mechanism having one axis of rotation mounted to the flange, wherein the first and second members comprise an open configuration and a first closed configuration providing a first gap between an inner surface of the first and second members and an outer surface of the proximal portion of the tubular body and a second closed configuration providing a second gap between the inner surface of the first and second members and the outer surface of the proximal portion of the tubular body;
wherein the first gap accommodates a first vascular graft having an inner perimeter matching the outer perimeter of the proximal portion of the tubular body and a first wall thickness and the second gap accommodates a second vascular graft having an inner perimeter matching the outer perimeter of the proximal portion of the tubular body and a second wall thickness different than the first wall thickness;
whereby continuous flow is provided from grafts of different wall thicknesses through the connector and into the blood conduit.

Abstract
A connector for fluidly coupling proximal and distal tubular segments of a fluid conduit is provided. In one embodiment, the connector can include a connector body having an outer surface defining a first outer perimeter and an inner surface defining a lumen. The connector can also include a connecting device having an open configuration and a plurality of closed configurations. The connecting device can include first and second members configured to engage each other to secure the fluid conduit to the connector. The connecting device can also include a plurality of closed configurations for securing fluid conduits of different sizes.
