Endoluminal medical access device

摘要: An endoluminal medical access device (1) is disclosed that devised for delivery to an extravascular target site (5) at a vasculature of human or animal body vasculature, such as the microvasculature. The (1 ) comprises hollow (112) arranged around continuous channel (113) ends in distal end (100) and penetration portion (102) extend across tissue wall said microvasculature (4) provide communication with through least partly apposition wall, proximal connection section (101 ), which proximally adjoins (102), optionally intrusion depth limit unit (116, 118) and/or separation (115) controllable from connected (110) body.
