In recent years, more and more medical operations are done minimally invasive. Intervention radiology is a medical specialty which uses minimally invasive techniques to diagnose, or treat diseases. Instruments like needles and catheters are used by radiologists to enter the network of veins and arteries guided by image modalities. A complex...

Sensory nerve roots (DRGs) that emerge from the spinal cord can be stimulated with electrodes to prevent neuropathic pain. Proper functionality of DRG stimulation strongly depends on electrode placement, and conventional pre-curved introduction shafts limit DRG coverage of the implanted electrode lead. The goal of this thesis is to design an...

Brain cancer is a major health problem and currently used treatment methods are considered suboptimal. Micro-brachytherapy with radioactive Holmium-166 showed to be an effective palliative care method for primary and metastatic brain tumors and intratumoral administration with holmium microspheres (HoMS) showed very promising results with...

Flexible steerable needles can follow curved paths inside the human body, allowing to steer around objects, to adjust for mispunctures, and to reach multiple targets. However, the designs of existing ultra-thin (diameter < 1 mm) steerable needles require axial rotation of the needle to steer in 3D space causing needle twisting, which results...

High accuracy and precision in reaching target locations inside the human body is necessary for the success of percutaneous procedures, such as tissue sample removal (biopsy), brachytherapy, and localized drug delivery. Flexible steerable needles may allow the surgeon to reach targets deep inside solid organs while avoiding sensitive structures ...

Flexible steerable needles can follow complex curved paths inside the human body. In a previous work, we developed a multiple-part steerable needle prototype with a diameter of 1.2 mm, inspired by the ovipositor of parasitoid wasps. The needle consisted of seven nickel-titanium longitudinally aligned wires held together at the tip by a...

In many percutaneous interventions, such as biopsies and brachytherapy, accuracy in reaching a specific target inside the human body is necessary for the success of the procedure. Maneuvering to the target site is challenging, particularly if sensitive structures such as blood vessels have to be avoided. For maneuvering along a curved trajectory,...

Percutaneous procedures are minimally invasive medical procedures that use needles to locally operate on a target in a patient’s body. The precise placement of the needle in the body is a challenging task that can affect the quality and efficiency of these procedures. Needle insertion accuracy may be improved by robot-assisted control of...
