Abstract
The invention includes a shunt for at least partial implantation into a patient that includes an elongated conduit having at least one lumen therethrough, that includes a proximal end for receipt of bodily fluids for flow through the shunt and a distal end for discharge of the bodily fluids from the shunt, and a long term source of at least one occlusion resistant agent, wherein said at least a portion of the at least one occlusion resistant agent can permeate through at least a portion of the elongated conduit. The invention also includes kits and systems.
Claims33
A shunt for at least partial implantation into a patient having a brain with a ventricular region and having an abdomen, comprising:
- an elongated conduit having a first lumen extending therethrough and a second lumen concentric about said first lumen along at least a part of said first lumen, wherein said elongated conduit comprises a proximal end configured for receipt of bodily fluids from said ventricular region of said brain for flow through said shunt and a distal end for discharge of said bodily fluids from said shunt into said abdomen;
- and
- a long term source of at least one occlusion resistant agent fluidly coupled to said second lumen, wherein said at least one occlusion resistant agent can permeate through a permeable portion of said second lumen into the first lumen.
A kit comprising:
- a shunt for at least partial implantation into a patient having a brain with a ventricular region and having abdomen comprising:
- an elongated conduit having a first lumen extending therethrough and a second lumen concentric about said first lumen along at least a part of said first lumen, wherein said elongated conduit comprises a proximal end configured for receipt of bodily fluids from said ventricular region of said brain for flow through said shunt and a distal end configured for discharge of said bodily fluids from said shunt into said abdomen;
- and
- a long term source of at least one occlusion resistant agent fluidly coupled to said second lumen, wherein said at least one occlusion resistant agent can permeate through a permeable portion of said second lumen into the first lumen;
- a valve;
- and
- a distal catheter.
