Personalized Medical Devices Reduce Treatment Time and Improve Healing Rates

Customized additive manufacturing of medical devices significantly improves healing outcomes for complex wounds by providing a superior seal and adapting to changes during treatment.

Bioengineering & Translational Medicine · 2023

Key Findings

01Customized devices successfully isolated the wound from intestinal content for 48–72 hours.
02Weekly wound dressing changes decreased significantly (from 23.63 ± 10.54 to 2.69 ± 0.65).
03Significant reductions in fistula size (longitudinal and transversal) and wound depth were observed.
04The design and manufacturing workflow for each device took an average of 230.50 minutes.

Application

Design takeaway

How to apply

For complex medical conditions requiring precise containment or support, explore patient-specific design using 3D scanning and additive manufacturing to create tailored devices that adapt to individual anatomy and treatment progression.

Project actions

01When designing a product for a specific user need, consider how customization can improve its effectiveness.
02Investigate how emerging manufacturing technologies like additive manufacturing can enable personalized solutions.

Method & Evidence

AimTo evaluate the effectiveness of personalized, additively manufactured devices for managing enteroatmospheric fistulas compared to standard treatments.

MethodCase study with iterative design and manufacturing.

ProcedureWhite light scanning was used to capture patient-specific wound geometry. This data informed CAD designs for custom devices. Devices were then additively manufactured and applied to manage the fistula, with redesigns occurring as the wound evolved during Negative Pressure Wound Therapy (NPWT). Healing metrics were tracked throughout the treatment period.

ContextMedical device design and wound management.

Variables

IVPersonalized additive manufacturing of medical devices.

DVWound isolation success, weekly cure frequency, fistula size reduction, wound depth reduction, treatment duration.

CVNegative Pressure Wound Therapy (NPWT) protocol, patient's underlying condition (enteroatmospheric fistula).

Strengths & Limitations

Strengths

+Demonstrates a novel and effective workflow for personalized medical device creation.
+Provides quantitative data on significant clinical improvements.
+Highlights the adaptability of the design to evolving patient conditions.

Limitations

The time taken for design and manufacturing (around 4 hours) might be a bottleneck for immediate clinical application in emergency situations. The long-term durability and biocompatibility of the additively manufactured materials would require further investigation.

Reliability & validity

The study's findings are supported by quantitative measurements of clinical outcomes (e.g., reduction in cure frequency, size, and depth). However, the lack of a control group and the case-study nature limit generalizability and direct causal claims without further validation.

Think critically

While additive manufacturing offers personalization, what are the potential scalability challenges and cost implications for widespread adoption in the healthcare sector?

Design Principles

"Personalization through advanced manufacturing techniques can optimize product performance and user outcomes in specialized applications."

This research demonstrates the commercial viability of additive manufacturing for producing patient-specific medical devices. By tailoring solutions to individual needs, designers can create products that not only perform better but also reduce overall treatment costs and patient suffering.

What This Means for Your Design

Making special medical devices just for one person using 3D printing can help wounds heal much faster and better than regular ones.
