    • 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.

    • A fiducial marker system (210a-c) comprises a first unit and a second unit. The first unit is patient affixable and comprises a partly spherical inner surface having a first center point that is adapted to receive a touch probe measurement head for measuring the spatial position of the center point. The second unit is releasably attachable to an outer surface of the first unit, and has a second center point, wherein the first center point and the second center point are substantially identical when the second unit is attached to the first unit. For stereotactic therapy, a patient is imaged with the first and second unit assembled. Then the second unit is detached. A stereotactic frame (300) is attached to the first units via arms. Thus frameless imaging is provided in a frame based stereotactic surgery system with high precision. Repeated assembly of the frame (300) to the first units, remaining in the patient, provides advantageous fractionized stereotactic radiotherapy.
    • 基准标记系统(210a-c)包括第一单元和第二单元。 第一单元是可耐用的,并且包括部分球形的内表面,其具有适于接收用于测量中心点的空间位置的测头测量头的第一中心点。 第二单元可释放地附接到第一单元的外表面,并且具有第二中心点,其中当第二单元附接到第一单元时,第一中心点和第二中心点基本相同。 对于立体定向治疗,患者以第一和第二单元组装成像。 然后第二个单元是分离的。 立体定向框架(300)通过臂附接到第一单元。 因此,在基于帧的立体定向手术系统中提供无框架成像,其精度高。 保留在患者体内的框架(300)重复组装到第一单元提供有利的分级立体定向放射治疗。
