Abstract
Medical devices including vascular access kits and related system and methods are disclosed. In some embodiments, a vascular access system may include a first conduit, a second conduit, and an expandable stent that is coupled to both the first and second conduits such that there is a continuous lumen between the first conduit and the second conduit. Methods of deploying the vascular access system within the body of a mammal, more particularly, a human patient are disclosed. Methods of bypassing a section of vasculature of a mammal, more particularly, a human patient are disclosed. The vascular access system, when implanted and assembled, may be a fully subcutaneous surgical implant.
Claims14
A vascular access system, comprising:
- a first conduit comprising a second central end;
- a second conduit comprising a first central end;
- an expandable stent configured to be deployed to couple to the second central end of the first conduit and to the first central end of the second conduit;
- and
- a first pull sting operably coupled to the expandable stent and configured to allow expansion of the expandable stent when pulled,
- wherein in an expanded configuration, a first portion of the expandable stent is disposed within the second central end of the first conduit so that an outer surface of the first portion is in contact with an inner surface of the first conduit and a second portion of the expandable stent is disposed within the first central end of the second conduit so that an outer surface of the second portion is in contact with an inner surface of the second conduit, such that there is a fluid-tight continuous lumen from the first conduit to the second conduit,
- wherein one or both of the first conduit and the second conduit is configured to be accessed extravascularly for hemodialysis, and
- wherein the expandable stent is a self-expanding stent.
