New Publication – A biomimetic urethral model to evaluate urinary catheter lubricity and epithelial micro-trauma

A new paper from the Medical Device Design Group entitled A biomimetic urethral model to evaluate urinary catheter lubricity and epithelial micro-trauma has been published in Journal of the Mechanical Behavior of Biomedical Materials. In the study, Owen Humphreys et al. developed a human urethral epithelial cell-seeded model of the urethra which was then used to measure the Coefficient of Friction (CoF) of four brands of commercially-available hydrophilic-coated intermittent catheters.

Group Member Oisín Byrne receives Fulbright Irish Student Award

Group member and 3rd year PhD candidate Oisín Byrne has received a Fulbright Irish Student Award to conduct research over in the Therapeutic Technology Design and Development Laboratory of Professor Ellen Roche at Massachusetts Institute of Technology. Oisín’s PhD research focuses on 3D printing medical grade polymers onto cylindrically shaped substrates with applications in coronary artery bypass grafting. As a Fulbright Student to Massachusetts Institute of Technology, he will conduct research into ways to promote the mechanical coupling of medical devices to tissue.

 

 

New Publication – Kinematic error modeling and error compensation of desktop 3D printer

A new paper entitled Kinematic error modeling and error compensation of desktop 3D printer has been published in Nanotechnology and Precision Engineering. In this paper Shane Keaveney et al. investigate how higher accuracy can be achieved on low-cost 3D printers, enabling the impact and functionality of produced components to improve considerably.  The paper has recently been featured in the article Irish Researchers Examine Benefits of Kinematic Error Modeling & Error Compensation in 3D Printing on the popular 3D printing website 3dprint.com.

PhD student Oisín Byrne wins BOC Gases Symposium 2018

Second year biomedical engineering PhD student Oisín Byrne has been announced as the winner of the BOC Gases Symposium 2018. He presented a pitch of his work to a multidisciplinary audience of engineering staff and students from the School of Mechanical and Materials Engineering on March 12th.
His presentation entitled “3D printing of polymers onto the abluminal surface of cylindrical tissue samples” secured him the BOC Gases sponsored prize fund of €1300 and consequently, he participated in the prestigious Sir Bernard Crossland Symposium which was hosted by UCD this year on April 25th.
Competing with 23 posters from other Mechanical Engineering Institutions across Ireland, he received 3rd prize at this event and €200. As a member of Dr. O’ Cearbhaill’s Medical Device Design group, the aim of Oisín’s project (co-funded by Cúram, the SFI Centre for Research in Medical Devices and Neograft Technologies Inc.) is to provide an intra-operative method for improving the mechanical performance and longevity of saphenous vein grafts that are routinely used in Coronary Artery Bypass Grafting (CABG) procedures. He seeks to harness the unique benefits of additive manufacturing technology to provide a patient-specific graft reinforcement method in order to improve graft performance compared to the current state of the art reinforcing methods.
