Lymph node replacement construct

A method of installing a lymph node replacement construct, comprising the steps of:

• implanting the lymph node replacement construct into a lymphoid drainage system of a subject, the lymph node replacement construct comprising:
• a body comprising at least one first access port on an exterior of the body, at least one second access port on the exterior of the body, and a plurality of first conduits within the body, wherein the plurality of first conduits are parallel or substantially parallel to one another within an interior of the body to provide a plurality of separate parallel or substantially parallel flow paths within the interior of the body, wherein a flow pathway through the lymph node replacement construct comprises each first access port, each second access port, and the plurality of first conduits, wherein each first access port is fluidly connected with at least one second access port using at least one first conduit of the plurality of first conduits;
• wherein the implanting comprises positioning the lymph node replacement construct within the subject to provide a fluid connection between at least one lymph vessel of a first type and the at least one first access port, wherein each first access port is fluidly connected with a lymph vessel of the first type;
• wherein the implanting further comprises positioning the lymph node replacement construct within the subject to provide a fluid connection between at least one lymph vessel of a second type and the at least one second access port, wherein each second access port is fluidly connected with a lymph vessel of the second type.
