WASP: a Wasp-inspired Surgery needle for Prostate cancer procedures: Design and prototyping of a low-friction actuation mechanism

Prostate cancer is the second most frequently diagnosed cancer in men. A minimal invasive treatment for prostate cancer is transperineal laser ablation (TPLA), which involves inserting a needle containing a laser fibre into the prostate to induce local cell death. The ovipositor of the parasitoid wasp offers a solution to challenges in TPLA, as...

Erectiometer: A diagnostic device to measure nocturnal erections

The idea for this project was created by two Urologists at the Erasmus MC in Rotterdam. The design goal was to develop a diagnostic device that can be used to measure nocturnal (i.e. nightly) erections. The current device used to measure nocturnal erections was developed in the 1980s. There is a need for a modern tool that can be used in the...

Design of a Steerable Laparoscopic Aspirator-Irrigator: FlowFlex

Laparoscopy is a type of minimally invasive surgery in which instruments with long, slender shafts between handle and end effector are inserted through small incisions in the abdominal wall. A laparoscopic aspirator-irrigator (LAI) has a hollow shaft used to evacuate undesirable substances using a vacuum pressure, rinse tissue using a stream of...

AR-assisted craniotomy planning for tumor resection

A craniotomy is a procedure were a neurosurgeon has to open the skull to gain direct access to the brain. When a brain tumor has to be removed from a patient, the craniotomy position is of great importance. This mostly defines the access path from the skull surface to the tumor and thus also what healthy brain tissue will be removed to access to...

Towards improved orthopaedic drilling at hard to reach bone sites: The design of a compact Self-Feeding Angled Drill Attachment (SFADA)

Bone drilling is a crucial part of orthopaedic surgery. Internal fixation is a ommon orthopaedic procedure that requires drilling to improve healing of bone fractures. Tight spaces around hard to reach bone fractures impede the surgeon during the procedure. As a result there is an increased risk of complications such as thermonecrosis, overshoot...

Design the Next-generation Atrial Fibrillation Diagnosis Device: An off-hospital, continuous, long-term heart monitoring product

This is a 5-month master graduation project in collaboration with Praxa Sense to design the next generation Atrial Fibrillation diagnosis device. A long-term (more than one month) continuous, off-hospital diagnosis device is designed with the focus on user experience and diagnosis accuracy. There are several phases in this project including...

An Ultra-Low Power Temperature to Digital Converter: for Medical Applications in 180 nm CMOS

This thesis describes the design of an ultra-low power temperature to digital converter. It is intended to monitor the excess heat produced during the wireless charging of implantable medical devices such as pacemakers. The TDC is designed to achieve an accuracy of ±0.1 °C (3 sigma) from 27 °C to 47 °C, and ±0.3 °C (3 sigma) from -40 °C to 85 °C...

Design for the intraoperative assessment of tissue perfusion

Because of cancer in the colon, parts of this organ might be surgically cut out to eliminate this disease. After removal, the residual parts are connected by means of a suture. A leakage of such connection is a severe complication and potentially life-threatening for the patient and associated with a poor healing of this surgical wound. Adequate...

Null subtraction imaging for small aperture phased array transducers

In medical ultrasound imaging phased array transducers are used for non-invasive imaging. For 3D intra-cardiac-echography technical borders are reached since blood vessel size limits the dimensions of the array. This dimensional limitation lowers lateral resolution. To solve part of the problem, non conventional ways of lateral resolution...

Non-intrusive patient monitoring for pressure ulcer prevention: Group F - Test Group

Problem Definition<br/>This bachelor final project was an assignment given by the start up Momo Medical named: "Improving health care with technology". This project was to use their existing technology and ideas to create a system to prevent pressure ulcers. Pressure ulcer are the medical condition that happens when a patient is left too long in...

Creating a comfortable working environment for cath lab physicians: Design of a body support

This project is about developing a solution for cath lab physicians. A cath lab physician is a medical doctor, with a background in cardiology, neurology, electro physiology or radiology, who performs cath lab procedures. A cath lab procedure is a minimal invasive procedure in which a catheter is brought into the body of a patient via a small...

Health Dashboard: Improving telemonitoring and self-management of heart failure patients by design.

This project presents the result of a new proposal to improve telemonitoring and self-management for heart failure patients: The Health Dashboard. The Health Dashboard is designed for Philips in collaboration with the Reinier the Graaf hospital in Delft. It aims to reduce the chance on readmissions, to reassure heart failure patients about their...

The Haermonic Flush. Designing the next Pericardial Flushing Device

The goal of this graduation project was to design the next pericardial flushing device. The whole “Post Pericardial Flushing project (PPF)” was initiated by Dave Koolbergen and Johan Manshanden as a clinical study to introduce a new technique to actively flush the pericardial section of the human body after open heart surgery. The key...
