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

主权项 1. An endoluminal medical access device, devised for endoluminal delivery to an extravascular target site at a vasculature site of a human or animal body vasculature, wherein said device comprises: a hollow body that is arranged around a continuous channel that ends in an opening at a distal end of said device; wherein said hollow body comprises: a detachable elongate distal portion that is configured to perforate a tissue wall of said vasculature at said vasculature site in said body, to provide communication with said extravascular target site through said channel, and for positioning at least partly in apposition to said tissue wall, anda proximal portion, which proximally adjoins said distal portion at a proximal connection section; and a hollow separation section that is arranged at said hollow body for controlled separation of said distal portion from said proximal portion of said hollow body at said proximal connection section while said distal elongate portion is at least partly in apposition to said tissue wall to provide said communication with said extravascular target site through said channel.
