Abstract
A catheter for implantation into tissue, the catheter comprising a tubing having a lumen and defining an outer boundary between the catheter and the tissue when the catheter is implanted in the tissue, a healing dummy being insertable in the lumen with clearance so as to prevent tissue ingrowth from the tissue into the lumen when the healing dummy is within the lumen, wherein the healing dummy is removable from the lumen by pulling the healing dummy relative to the tubing out of the lumen, and a perfusion insert being insertable in the lumen when the healing dummy is removed from the lumen, being configured for supplying a perfusion fluid to the tissue so as to initiate interaction between the perfusion fluid and tissue, and being configured for collecting perfusion fluid after interaction with tissue.
