REALISTIC SIMULATION FOR LIFE SCIENCES
The application of simulation in early days of life sciences was bit less as it was more innovation-oriented field. But in present scenario where life sciences and medicinal research requires high end technology for the cure for the different diseases, the simulation plays a significant role. The benefits of using simulation software for life sciences include understanding the organ system, control of a disease and predicting the behavior of stents on body to name a few.
The solutions from SIMULIA products can be utilized by life science researchers for simulation for multiple equipments related to surgery and medicine. Also, various procedures are available in suite for simulation of human body. So, the researchers can understand the interaction of multiple devices with the organs and tissues of human body. Some biological processes and interactions that can be studied using simulation suite from SIMUSERV include Biology-related acoustics, bio-fluid dynamics, electromagnetic fields, tissue models and various others. Also, Abaqus solution can be used for examining the application of devices for monitoring blood, brain injuries and tissue modeling etc.
Implanted devices utilized in medical sciences to create a passage in some part of the body are referred to as stents. Esophageal stents, coronary stents, prostatic stents and vascular stents are some of the stent types. A catheter is normally utilized for delivering the stent through the skin in the body. Tantalum, stainless steel, polymers (silicones) and nitinol are some of the materials from which stents are produced.
SIMUSERV provides CAD-integrated FEA and SIMULIA solutions for efficient simulation of different types of stents. Various companies have utilized this simulation software for submissions related to the US FDA device approvals. Different phases of stent’s lifecycle can be simulated with processes including
- Production (constitutes annealing, laser cutting and insertion)
- Insertion (torsion, extension and bending)
- operation / Expanding
Due to rate-dependent and non-linear response, tissue modeling is generally considered complicated by researchers. Extended range of tissue types like connective, muscular, nervous and epithelial tissue adds to the complexity of tissue modeling.
Abaqus integrated FEA from SIMULIA can be utilized for elastic-hyperelastic nonlinear models. Various researchers have utilized these solutions for studying soft tissue deformation using connectors which is quite effective in cases of laparoscopic surgery. Motion and assembly of joints can be analyzed through contact capabilities in the simulation software.
There is a broad library for related to add-in subroutines for effective tissue modeling in the simulation suite.
There are multiple challenges that are faced during design and development of surgical instruments. Also, surgical tools and equipments face the issues related to efficiency, ease of application, dependability and safety. Design of these biomedical devices needs a combination of engineering principles along with computer simulation and biomedical technology.
SIMUSERV provides simulation solutions which ensure effective design and development of biomedical apparatus along with its assembly and use. Using support for DMP and SMP systems, researchers can design state-of-the-art surgical instruments. The simulation suite comprises of piezoelectric structural interaction which is vital for design of various instruments. Also, product assembly and development related simulation is part of the solution provided by our company.
Common joints which undergo replacement in present scenario include knee, shoulder, hip and ankle etc. Zirconia, silicon nitride, alumina and silica are some of the commonly utilized materials in joint replacement. Other materials for joint replacement comprises of complex materials lie titanium, stainless steel and UHMWPE (Ultra High Molecular Weight Polyethylene) to name a few. It is made sure that the materials have features like medical imaging related compatibility, toughness and biocompatibility.
The designers of these artificial joints have a challenge to develop and deploy without spending a fortune. Also, simulation of these devices is complex due to friction, wear and contact characteristics of these devices.
SIMULIA’s Abaqus integrated with FEA suite comes as a solution for all challenges faced by artificial joint designers. It provides simulation related mechanics, assembly of joints and failure modes which decreases the complexity to a greater extent. Also, these simulations have been already utilized by our clients to receive approval from regulatory authorities. Numerous material models are present in the library of the suite for simulation.
