<p>Present and future for technologies to develop patient-specific medical devices: a systematic review approach</p>

Abstract

The main purpose of this investigation was to systematically review the literature regarding case studies on patient-specific implants and devices, with the goal of analyzing the process of developing custom-made medical devices. A content analysis was performed to identify design processes and methodologies implemented to develop devices such as implants adapted to bone geometries. Reverse engineering, computer-aided design, simulation of assets, and rapid prototyping technologies were selected according to their interoperability in a process framework for developing new products. Finally, results from the case studies and process stages identified in the consulted research were analyzed. These results showed a relationship between the scope and complexity of the process and the stage of technology integration of the patient-specific device development. The analyzed case studies were characterized by technical, scientific, and multidisciplinary components to achieve research goals. Likewise, integration of technologies using patient-specific technologies is needed for product development that converges into designing devices, such as implants, biomodels, and cutting drilling guides.

Application of Computer-Aided Reverse Engineering System in the Design of Orthotic Boots for Clubfoot Patients

“…Therefore, the product is expensive and needs high skills of a shoemaker. It was demonstrated previously [10,[28][29][30][31] that the customized design and production methods for orthotic shoe insoles utilized such technology: namely digital surface capture, CAD / CAM, CNC, and adaptive manufacturing. However, all of these works were not integrated from the design stage to the fabrication process and product testing on patients [8,18,24,32].…”

“…Alternatively, the implementation of CARE system technology and the RID method is proposed to design and to manufacture approaches to customize shoes with a specific size and shape. Hence, the prosperous use of technology for creating products has also been reported by several previous researchers [7][8][9][10]. Modern reverse engineering (RE) technology offers the product design process quick, precise, duplicating an actual physical model.…”

“…Further, foot deformities are congenital disabilities found in different types such as flat feet, metatarsalgia, high heels, and clubfoot [6][7][8][9][10]. In daily activities, persons with clubfoot frequently need shoes (sandals and shoes) to walk, run, jump and stand.…”

A Conceptual Blueprint for Making Neuromusculoskeletal Models Clinically Useful

“…Second, it is worth trying since the same computational design approach has revolutionized the design of products in the aerospace, automotive, heavy equipment, medical device, and numerous other industries [45][46][47][48][49][50]. In the early 1990s, Boeing was faced with the challenge of bringing a new long-range commercial airplane to market with significantly reduced development time and cost.…”

Structure, properties, and bioactivity of 3D printed PAEKs for implant applications: A systematic review

“…Yet, these implants provide limited solutions in addressing patient‐specific complexities 9,10 . Customized implants, on the other hand, are designed to fit precisely in the patient's anatomical defects or malformations 11 . In the future, POC AM as an advanced technology will allow individualized reconstruction in such complex cases considering its high adjustability, cost‐effectiveness, and shorter lead time, which is crucial for trauma cases or other time‐critical medical interventions and not feasible with traditional manufacturing methods 12 .…”
