Intro

Design Collaboration Journey

Designest collaborated with Innoventric to elevate their groundbreaking TRILLIUM™ medical device, transforming a complex surgical tool into a refined, user-centric instrument for treating severe tricuspid regurgitation.

Our partnership with Innoventric focused on enhancing the device's visual and ergonomic potential, bringing a fresh perspective to medical device design that prioritizes both functionality and user experience.

Design Strategy

Agile Design: From Concept to Precision

Our design journey with Innoventric embodied a dynamic, iterative approach. Continuous prototyping became our methodology, with dozens of physical and digital iterations. Each prototype underwent rigorous testing, bringing us closer to the optimal design. We engaged in:

  • Frequent design sprints

  • Rapid physical prototyping

  • Surgical environment simulations

  • Extensive feedback loops with medical professionals


The process was relentless – breaking down, rebuilding, refining. Every prototype brought us closer to the perfect balance of functionality, ergonomics, and surgical precision.

DFM & Production

Design for Manufacturing: Engineering Excellence

Transforming innovative design into a manufacturable product requires deep technical expertise. Designest worked closely with Innoventric to:

  • Optimize designs for injection molding

  • Minimize manufacturing complexities

  • Maintain design integrity throughout production


Our long-standing manufacturing partner brought critical capabilities:

  • Medical-grade material expertise

  • Stringent quality control processes

  • ISO 13485 medical device manufacturing certifications

  • Advanced injection molding technologies

Human Factors & Mechanical Design

Mechanical Development: Handle Precision Engineering

We tackled critical mechanical challenges across three key handle components:

​​

  1. Threaded Drive Rod Transformation & Main Handle Optimization

​​

  • Converted from CNC-milled metal to injection-moldable component

  • Reduced manufacturing costs and lead times

  • Simplified supply chain complexity

  • Engineered a slim, low-diameter handle to maximize grip and force transfer

  • Added specialized texture to enhance handling during critical surgical moments

  • Designed for the most demanding surgical interaction point​​​

   2. Proximal Handle: Surgical Intuition

​

  • 360-degree angle printing for real-time positioning

  • Rectangular profile enabling angle understanding without visual confirmation

  • Integrated Innoventric brand language into functional design

​

   3. Distal Handle: Precision Grip

 

  • Crafted hard-edged ribs for firm, precise grip

  • Optimized for the critical final deployment twist

  • Ensured maximum control during the most crucial surgical stage

Design Language

Drawing from Innoventric's core brand identity, we developed a holistic design language that creates visual harmony across the entire device system. By carefully implementing consistent angle proportions and geometric principles inspired by the company's visual DNA, we ensured that each component speaks a unified design dialect - from the intricate handle textures to the precise mechanical interfaces. This deliberate approach transforms the medical device from a collection of parts into a cohesive, visually integrated system that communicates precision, intentionality, and professional sophistication.
