Innovative medical devices

Sensile Medical AG, a medical devices company based in Haegendorf, Switzerland, develops and produces innovative rotary pumps for highly precise dosing and application of liquids. Starting from the first development, the company has used Solid Edge® software from product lifecycle management (PLM) specialist Siemens Digital Industries Software for 3D computer-aided design (CAD). Later it was supplemented by Femap™ software for simulation and NX™ software for computer-aided manufacturing (CAM) for numerical control (NC) programming.

Using the industry-leading Teamcenter® software for product data management (PDM), the company is heading for future success: the Siemens Digital Industries Software applications empower strong growth and compliance to various international requirements and standards of the industry.

When the company was founded, it focused on the SenseCore technology for precise drug delivery: the core element consists of only two micromechanical plastic parts – a housing and rotary pump shaft. ”The main benefit is simplicity,“ explains Daniel Grossenbacher, head of mechanical engineering at Sensile Medical. ”Without any additional valves, the pump sucks the fluid in one stroke and injects it during the same rotation.“

When the company was evaluating CAD systems, many of the solutions failed to model the complex geometry of the housing. ”Comprehensive features for surface creation were an important criterion when selecting Solid Edge,“ recalls Gerhard Eimer, managing director of Quadrix AG in Flawil, Switzerland, a market-leading value-added reseller for Siemens Digital Industries Software.

A startup company, Sensile Medical holds a family of more than 30 patents concerning this technology. The small, compact injection-molded parts require manufacturing accuracy within hundredths of millimeters. Today, a broad range of innovative products has evolved from the core technology.
