Patents & Inventions

Engineering ideas into medical technologies.

My medical device research has contributed to four international patent families, developed through collaborations with clinicians, engineers, and industry partners. These inventions address practical challenges in clinical procedures, from safer tissue sampling and image-guided interventions to guidewire management and joint reconstruction.

Together, they reflect an approach to innovation in which clinical needs inform engineering design, and engineering ideas are developed towards tangible technologies for patient care.

02

Motion Compensation Platform for Image-Guided Percutaneous Access (2019)

Bringing imaging and intervention into alignment.

An image-guided intervention platform intended to support percutaneous access to internal organs and anatomical structures while accounting for movement. The invention combines medical imaging, anatomical modelling, image registration, and engineering design to support more accurate targeting during minimally invasive procedures.
