Implantable actuators

In collaboration with urology and orthopaedic specialists, MPS Microsystems develops implantable actuators, an implant system or implant drive. The screw-nut assembly of these actuators, placed in a moist environment, is made from components and materials already approved for use in active implants, to reduce regulatory red tape. The drive system is placed in a dry environment and comprises a motor and reducer gear, the energy source and the electronic control; it is enclosed in a sealed biocompatible titanium shell. The motor torque is transmitted to the screw-nut assembly by a carefully sized coupling.

Heart pump

In collaboration with its customer, MPS Microsystems is working on a hydraulic system that ensures the pumping function of an artificial heart. Through the selection of suitable materials, perfect surface finishes and a complex, micrometer-precise geometry, this pump system is able to reproduce the natural heartbeat. The system is designed for approximately 230 million pulsating cycles, which corresponds to a service life of about 5 years.

Part of the components are assembled by material pairing and shrinkage to ensure perfect dimensional accuracy. The bonded joints of this heart pump (PEEK/aluminum and PEEK/steel) are made on plasma-prepared surfaces, which ensures the high requirements and reproducibility over time.

Implantable pump

MPS Microsystems has developed an implantable peristaltic pump with variable delivery based on customer specifications. Among other things, this programmable pump administers painkillers via a catheter directly into the patient's cerebrospinal fluid space. It consists of three arms, each with a titanium ball bearing in the tip. This keeps friction as low as possible when the pump rotates. Dosing accuracy is ensured, among other things, by a pressure spring that applies precisely the force required to close the flexible peristaltic tube connected to the catheter. The permanent guarantee of uniform pressure force and low friction is ensured by high individual part quality and careful assembly of the components in ISO Class 7 clean rooms. Torque, spring stiffness and geometry of the assembly are 100% controlled.

Microrobot

Placing pedicle screws or other implants in the spine requires procedures of extreme precision. To reduce the risk of human error and further develop minimally invasive microsurgical techniques, a company has developed a new surgical procedure using a miniature hexapod. MPS Microsystems was contracted to design and manufacture the unique microrobot. The Hexapod is the smallest of its kind on the market, measuring 50 mm in diameter, 80 mm in height and weighing 330 grams. The unique structure of the miniature Hexapod consists of 6 linear actuators.
