TDMG was chosen to help develop surgical equipment for a startup Canadian company
offering novel surgical procedures. The surgical equipment developed is related to
specialized suturing and ways of applying these sutures. This project is currently
underway with initial prototypes already made. The concepts in this development program
involve minute features which can only be produced using micro-injection molding
techniques. The project is shifting to testing, after which, it is expected that
final fine-tuning will be performed on the design prior to beginning the regulatory
approval process and manufacturing process development.
In related fields, TDMG has assisted a number of medical and pharmaceutical companies
in developing some of their products. Another project involved the design and
development of a heat exchanger unit for an intra-vascular temperature management
system. This system provides cooling or heating to patients who may be in critical
condition or undergoing surgery. TDMG’s role consisted of developing the heat exchanger
part of the system by performing CFD (flow and thermal) analysis of the system. The
results were used to optimize the heat exchanger section of the unit.
Yet another medical project involved the analysis of a collet feature on a dental
device. The collet had specific requirements in terms of when it needed to engage
and disengage. These requirements involved load application as well as centrifugal
force effects due to rotation. In order to optimize the collet geometry, a finite
element analysis was performed to estimate deflections under various applied forces.
The results of this work allowed the customer to properly dimension the collet so
that it would perform as requested under all operating loads and conditions.
