Minimally Invasive Sentinel Lymph Node Biopsy
Finding a less invasive alternative to an existing procedure
Sentinel lymph node biopsy (SLNB) is a procedure that is used to determine the stage of disease of melanoma patients and determine further treatment. However, the morbidities accompanied with this procedure are not negligible (e.g., wound infection, lymphoedema and seroma). With

Prototyping a novel wearable device for post-stroke hand rehabilitation
The human brain integrates tactile sensory information from the fingertips to efficiently manipulate objects. Sensory impairments due to neurological disorders, e.g. stroke, largely reduce hand dexterity and the ability to perform daily living activities. Several feedback augment

The MyoGrab Hand
Development of a functional low cost myoelectric upper limb 3D printed prosthesis
Background: Last decades myoelectric prostheses have become more usable, functional and reliable. Yet, the cost of myoelectric upper limb prostheses are still a hindering factor of widespread usage of the prostheses. In developing countries, where the demand for prostheses is rel
...
Background: The majority of the amputated population is living in low-resource countries, but only a small minority has access to rehabilitating services. The accessibility of upper limb prostheses in these countries is poor due to limited technical and medical resources. 3D prin

Transcended Manufacturing
The mass-production of one-of-a-kind products
The project is divided into three sub-assignments: - A future manufacturing context must be envisioned and the most important requirements synthesized. - An implementation of this envisioned manufacturing system must be developed and validated. - An exemplary-product producibl

A New Take on Prosthetic Wrists
The Development of a 3 DoF, Hydraulically Powered Wrist Prosthesis
Background: While new prosthetic hands are developed to increase functionality and allow more complex movements, prosthetic wrists are researched less. Although there are wrists available, primarily featuring 1 degree of freedom (DoF), only a few prototype 3 DoF wrists are curren

Radiofrequency ablation (RFA) is a localized thermalintervention technique with the purpose to destroy small tumours (< 3 cm) byheating the tumour tissue. Due to various challenges with targeting andvisualisation during RFA, the clinical need of steerable ...
Lab-on-a-chip for individual cell response to light stimulation
A three-layer MEMS device
Analyzing the different signaling pathways of cells is key in understanding the basic functions of the cells in all organic systems from algae to humans. Not only do they help solve our questions on how organisms function, they also allow for new cures to be explored. A large var

Calcification & Fibrous Tissue Characteristics in Atherosclerotic Plaques
A Combined Analysis and Modeling Approach
Atherosclerotic plaque rupture is the main cause of acute myocardial infarction and stroke, the two leading causes of death worldwide. Rupture of plaque tissue is a mechanical event, where plaque stress or strain locally exceeds its strength. Biomechanical studies agree with hist

Highly Automated Driving
Transitions of control authority using Haptic Shared Control
The arrival of highly automated vehicles introduces a new interaction between the vehicle and driver. System limitations during highly automated driving require the driver to be ready to take back control at request.
Previous studies on the take-over process concluded that th ...

Medical Instrument Tray Optimization
Combining Use Rates, Expert Opinions and Risk Analyses
The operating room and central sterile supply department (CSSD) are two
resource-intensive healthcare departments. Reducing the environmental and financial impact of these departments is of great importance in the global debate on sustainability. Removing unnecessary items fr ...

A BIO-INSPIRED FINGERTIP
3D Printed Surface Patterns and Their Role in Surface Friction: An Experimental Study
In the field of prostheses, significant developments have been accomplished so far in low-cost prosthetic limbs using 3D printing technology. However, when it comes to prosthetic hands, 3D printed prosthetic hands are still limited in their grasping ability, such as the adaptabil

A sit-snowboard is a weight supporting mechanism that allows people with lower extremity impairments to perform the sport of snowboarding. Comfort and control of the Twinrider (the only sit-snowboard on the market) are insufficient for advanced riders who rea ...
The design of a single-insertion multiple specimen biopsy instrument
The development and evaluation of a novel core-needle biopsy device
Background: When a suspicious lesion is detected, a thorough examination is essential for the diagnostics of the lesion. Information about the nature and character of the lesion is crucial for the determination of the disease and an appropriate corresponding treatment plan. Takin

The NeuroPunch
A single-handed rotatable neurosurgical punch capable of storing multiple bone pieces
During endonasal pituitary surgery - an approach of skull base surgery - long slender instruments are inserted through the nose of the patient, in order to remove a pituitary lesion. One of the instruments which is repeatedly used is the surgical punch, which is able to remove pi
